Can SpaceX Put A Man On Mars By 2031?
SpaceX (which is short for Space Exploration Technologies) is either the most brazen company ever formed by man or America’s last great hope for expanding free civilization across the star system.
Either way the company has announced plans to conquer the red planet before 2031, which is about six years before NASA’s original plan and four years before Russia’s.
The only question is, “do they have the right stuff?”
Note: Fast forward to 13:05
“We’ll probably put a first man in space in about three years,” Elon Musk told the Wall Street Journal Saturday. “We’re going all the way to Mars, I think… best case 10 years, worst case 15 to 20 years.” [...]
“Our goal is to facilitate the transfer of people and cargo to other planets, and then it will be up to people if they want to go,” said Musk, who also runs the Tesla company which develops electric cars. (Physorg.com)
With NASA nervous about landing anything over a ton upon Mars (let alone dealing with the side effects of cosmic radiation), one has to wonder how SpaceX plans on achieving this goal when the US government themselves are hesitant about the idea.
While SpaceX does have the fortitude to encounter Mars within our lifetime, there are at least a few problems the company will have to address if they want to see someone survive the trip towards Mars (let alone return home from it).
Exiting The Home World
Truthfully this should be SpaceX’s least difficult task, as their upcoming rocket (the Falcon Heavy) not only out performs their rivals, but their rocket is even less expensive than China’s (who usually have the cheapest price around).
While Falcon Heavy lacks the lift to help humanity break Earth orbit (let alone land on the Moon), it wouldn’t be surprising to see the company develop a Mars bound rocket within a decade (or even 15 years).
Into The (Radioactive) Black
Despite the celestial heaven’s serene appearance, the blackness of space harbors deadly cosmic radiation that can reduce an astronauts IQ to the level of a vegetable (not to mention wreak havoc upon the heart as well).
If SpaceX aspires to trek the vastness of space in order to help humanity migrate upon Mars, they will need adequate shielding to protect them from being microwaved by the universe.
Although layers of lead around the craft would suffice, it might be wiser to use magnetic shields instead which would help reduce the amount of weight SpaceX has to launch into orbit.
The private space firm might also want to ponder patients using anti-radiation drugs too, although building a radiation safe cabin (surround by lead) would be advisable.
Micro Gravity Blues
Despite the joys of weightlessness, the fact is that humans were not designed to thrive in micro gravity.
The lack of gravity can not only cause our muscles to waste away, but also weaken our bones as well. Worse, our immune system tends to slack off while at the same time provoking dangerous bacteria to become even more lethal.
While electrical shocks and omega-3 seafood could save future explorers muscles and bones (as exercise is not enough), SpaceX will need to figure out a sensible way of mimicking gravity upon their rocket lest future explorers skip landing upon Mars due to being too weak to survive Martian gravity.
Note: Do any readers have any ideas on tackling the gravity problem? Aside from spinning techniques that is.
Final Destination: Crimson Soil
Even if SpaceX finds a way to cheaply exit our homeworld and avoids succumbing to the effects of radiation and micro gravity, finding a way to safely land upon Mars will prove to be a daunting challenge.
It might be wiser for SpaceX to simply land their larger craft upon the Martian moon known as Deimos instead, and ferry astronauts to the surface using smaller space craft.
Since the red planet lacks an abundance of water in liquid form, SpaceX could use Ballutes to slow the craft down, enabling a human vessel to gently touch down upon the red planet instead of smashing into its surface.
Note: Future red planet residents might want to consider building a Skyhook (aka space elevator) upon Phobos, which could reduce the cost of landing upon Mars, as well as launching off of the crimson world.
Can SpaceX Put A Man On Mars?
Truthfully only time will reveal whether SpaceX can send a man (or woman) to Mars within the next two decades.
However if SpaceX is successful we could witness a new age for humanity, one that envisions us leaving our Earthen cradle in order to explore the solar playground around us.

Could Solar Wind Power Martian And Lunar Colonies?
When it comes to settling our nearest neighbors, both Mars and Luna (aka the Moon) present unique challenges as far as energy goes.
Although one could always import numerous mini-nuclear reactors upon each respective world from Earth (controversy aside), it may make more sense to rely upon the fiery breathe from our Sol star.
Instead of physically rotating a blade attached to a turbine, the proposed satellite would use a charged copper wire to capture electrons zooming away from the sun at several hundred kilometers per second.
According to the team’s calculations, 300 meters (984 feet) of copper wire, attached to a two-meter-wide (6.6-foot-wide) receiver and a 10-meter (32.8-foot) sail, would generate enough power for 1,000 homes.
A satellite with a 1,000-meter (3,280-foot) cable and a sail 8,400 kilometers (5,220 miles) across, placed at roughly the same orbit, would generate one billion billion gigawatts of power.
That’s approximately 100 billion times the power Earth currently uses. (Discovery News)
Although this idea is being proposed for usage upon our home world, it might be easier (not to mention wiser) to adapt it to power future colonies upon the Moon as well as for Mars.
Even though the first explorers of Mars and Luna will use solar power to help keep the lights on, using our Sun’s solar wind could allow us to power cities without having to rely upon nuclear fuel imports from Earth.
Perfecting this technology would allow Lunar settlements to operate during the 2 weeks of darkness while Martian outposts might be able to transform one of their asteroid moons (preferably Deimos) into a gigantic power station that could help power Martian cities every few days.
While it’s skeptical that something like this would be allowed near Earth (due to the environmental consciousness of our global governments), it would make more sense when used for off world colonies upon Luna, Mars and beyond.

Read MoreVideo: VASIMR May Be The Only (Safe) Way To Reach Mars
(Image Credit: NASA)
Before we can build homes, fertilize the soil and raise up forests upon the red planet (not to mention bring our animal friends as well), we are going to have to figure out a way to safely get to Mars.
Despite the advances of chemical rockets, taking a 6 month journey to that crimson world would not only be unreasonable (as you would have to pack a lot of food and water for the journey) but dangerous as well due to space radiation.
In order to shorten the time span between the blue and red worlds, we may have to resort to Variable Specific Impulse Magnetoplasma Rocket’s (aka VASIMR).
(video via Spaceports)
(Space.com) Future Mars outposts or colonies may seem more distant than ever with NASA’s exploration plans in flux, but the rocket technology that could someday propel a human mission to the red planet in as little as 40 days may already exist.
A company founded by former NASA astronaut Franklin Chang-Diaz has been developing a new rocket engine that draws upon electric power and magnetic fields to channel superheated plasma out the back. That stream of plasma generates steady, efficient thrust that uses low amounts of propellant and builds up speed over time. [...]
A mission trajectory study estimated that a VASIMR-powered spacecraft could reach the red planet within 40 days if it had a 200 megawatt power source. That’s 1,000 times more power than what the current VASIMR prototype will use, although Ad Astra says that VASIMR can scale up to higher power sources.
Although VASIMR could help shorten the trip towards Mars, future astronauts would probably still need a magnetic shield to protect them from the ravages of space radiation.
It may be wise for NASA to team up with Ad Astra in order to perfect this rocket, as it could enable us to not only reach and settle Mars within our life time, but perhaps Callisto, Ganymede and Saturn’s Titan as well.
Read MoreTerraforming Mars Impossible Due To The Sun?
(Image: Terraformed Mars, Artist: Ittiz)
It looks like humanities hope of turning Mars into a second Earth may never translate into reality thanks in part to the red planet’s lack of a magnetic field.
Scientists have discovered that our Sun’s solar radiation may thwart all attempts at increasing the atmospheric pressure of the crimson world, which means we may never get the chance of witnessing a green Mars, let alone a blue one.
(Discovery News) Scientists have identified a sort of double-whammy solar super wave that is responsible for blowing away air from Mars and keeping its atmosphere thin, frigid and downright inhospitable for any possible future travelers.
The waves happen when one stream of solar wind is overrun and amped up by another, faster gale of solar particles. That creates a flying traffic jam of particles that slam into Mars as one large pulse. [...]
When Edberg and his colleagues compared these events at Mars to the flow of heavier atoms blowing past Mars Express, they discovered that fully a third of Martian air loss happens during the 15 percent of the time when doubled-up solar wind pulses hit the planet.
Although this means that Mars may never become a second eden (unless we can create a global magnetic field), it does not mean that humanity will never settle the planet en mass.
Future colonists will have to adapt to living within specialized biospheres (with portable magnetic shields to protect them from radiation), although doing so is probably much cheaper than terraforming the entire planet.

Read MoreCould ‘Peepoo Bags’ Help Fertilize Martian Soil?
(Image Credit: Peepoople.com)
Unlike our beloved Earth, Martian soil is very hostile to terrestrial plants.
While this may not hinder our efforts to visit the red planet, it will prevent us from raising crop and planting forests upon this barren dusty world.
Fortunately there seems to be an innovative invention that may resolve this issue–although it may turn a few noses.
(Physorg.com) While efforts have been made to design inexpensive toilets, Swedish inventor Anders Wilhelmson is taking an even more low-tech approach to the problem. He has designed the “Peepoo,” a biodegradable plastic bag that serves as a single-use toilet for individuals in the developing world. After the bag is used and buried in the ground, urea crystals coating the bag sterilize the solid human waste and break it down into fertilizer for crops. Wilhelmson says that his company, Peepoople, can sell the bags for about 2 or 3 cents.
Not only would this be much cheaper than importing fertilizer from Earth, but I could also enable us to raise a few animals off world (like pigs, chickens and of course man’s best friend).
While utilizing our own waste would require the first Martians to maintain a high level of sanitization (perhaps via plasma gas?), it could be the only practical way for us to conquer the crimson world.

Read MoreThe 7 (Future) Wonders Of The Solar System
Two hundred years after the first man and woman graced the plains of Mars, humanity is still isolated to just one star system.
Despite an intense campaign by the Alpha Centauri Society, humans overall have little desire to travel between stars due to cost and technology.
Although this rowdy species has yet to claim their interstellar inheritence, they have transformed their solar playground around them, producing seven wonders that will go down in galactic history.
The Silver Stripes of Mercury
Originally conceived as a penal colony, industrial corporations decended upon Mecury after discovering large deposits of minerals and metals upon its surface.
While its close proximety to the Sun has made Mercury famous for its Magsail races, it’s the billions of solar panels that encircle the planet on the surface (in “neat” rows varying between 1-10 km wide) that make this world an engineering wonder.
The planets 100,000 residents use the energy produced during the Mecurian day to power the ores and cities on the dark side of the planet when it’s safe to work above ground (due to the Sol Star’s radiation).
The Bio Gardens of Luna Maria

Officially designated Luna Maria after the failed Lunar revolution (condemned by government and religious leaders on Earth), Luna Maria has transformed its appearence from a white barren wasteland into a “second Eden,” which now boasts 60 million residents.
After generating enormous wealth from exporting oxygen throughout the Sol System, Luna Maria has erected hundreds of thousands of enormous, interconnected biospheres upon 87% of its surface, giving Luna Maria the appearence of a miniture Earth from space.
Luna Maria’s artificial planetary magnetic field (the only one in existance due to cost) has allowed the moon to use bees instead of ants to pollinate its crops, producing gardens unrivaled throughout the star system (due to it’s 16.7% Earth norm gravity).
The Phobian Skyhook (Or Martian Space Elevator)
(Image Credit: Steve Bowers)
After failed attempts to construct a space elevator on Earth (due to infrequent yet devestating global wars), humanity was finally able to construct a skyhook on the Martian moon of Phobos.
This engineering feat has enabled Mars to inexpensively export its vast supply of water throughout the asteroid belt and inner Sol System, bringing mixed prosperity to the 8 million residents of Mars.
While the red planet’s globacanes prevent a space elevator touching the ground from ever being built, the Phobian Skyhook is an impressive site to see when orbiting this crimson world.
The Jovian Jewel Callisto
(Image Credit: Thomas Guilpain)
Originally established as a way station world during the Helium-3 rush (in which thousands sought to harvest the isotope for profit), Jupiter’s moon Callisto attracted millions of residents after being declared the safest radiation world after Earth.
Using its brother moon Ganymede as an agricultural world (due to it’s natural magnetic field), Callisto developed the means to feed its enormous population of 750 million, who built cities covering 96% of the entire surface.
Using robots to harvest radioactive materials from both Io and Europa to power its cities (as they are too dangerous to be visited by humans), Callisto brilliantly shimmers in the dark whenever it falls underneath Jupiter’s shadow.
The Beacon Towers Of Titan
Often declared as “an astronomer’s hell” due to it’s cloudy covering, Saturn’s moon Titan is considered a musicians heaven due to the richer sound that’s a result of it’s atmospheric presure and composition.
While Titan eventually became wealthy by exporting methane and ethane to the Sol System, the cloudy moon was extremly difficult to navigate as its crust rested upon a methane/ethane mix, causing it to “slightly drift” and rotate due to the worlds strong winds.
Since traditional forms of GPS were utterly useless, numerous 1.5 kilometer tall Beacon towers (beaming out intense radio waves) were constructed thoughout the moon, giving its 4 million residents a faux GPS system (making travel and commerce throughout the world a lot easier for all).
The Floating Cities Of Uranus
(Image Credit: Star Wars, original artist unknown)
Originally built by various Terrian corporations to harvest methane and helium-3 within the clouds of this ice giant, these floating cities soon became tourist attractions for the more affluent seeking to escape the low gravity life of lunar worlds orbiting gas giants.
These giant orbital space stations boast near Earth gravity, and mimic the daylight cycle on Earth by floating around the enormous ice giant which its residents call home.
While estimates put the total population between 80,000 wealthy souls, these floating cities are known to have hundreds of thousands of visitors pass through their space ports each standard year, many of them heading towards the Neptunian Lagrange asteroid fields.
The Plutonian Ice Bridge (aka Solar Bridge of Pluto And Charon)
Boasting no more than 50,000 brave souls, this world was originally settled upon by government scientists from various Terrian, Martian and Callistian nations seeking to conduct experiments considered too hazardous (and/or controversial) on their respective home worlds.
While the world and its smaller moon hold little value (both visually and economically), one interesting feature of this binary system is the solar bridge connecting both Pluto and Charon together.
This engineering feat was originally built to reduce the cost of travel between both worlds via rockets although conspiracy theorists have their own conclusions for its existence (none of which will be cited here).
What about Earth?
Although the human race has made great strides in establishing colonies throughout the Sol System, most of its 20 billion individuals reside on the birth planet Earth.
While Earth is still home to some of the greatest scientific discoveries known to man (and women), there are no great engineering wonders to speak of, aside from the beautiful beaches, mountains and vast blue oceans that distinguish our home world from every other sphere that orbits our star.
Update (11/24): Corrected grammatical errors. Thanks!
Read MoreMoon: Oxygen, Oxygen Everywhere, But We’ll Need Hydrogen To Drink
The discovery of water within the lunar soil earlier set off a buzz amongst the space geek community.
While Luna’s revelation inspired dreams of interplanetary conquest, the fact is that the Moon’s soil is far too dry for us to use as a fountain, let alone for watering crop.
Instead of digging through 10 million tons of soil in order to get 10,000 liters of water, it might be easier (and cheaper) to simply ship tanks of hydrogen instead.
Unmanned space craft could help open up the lunar frontier by steadily seeding Luna with thousands upon thousands of hydrogen tanks upon it’s surface.
Since about 40% of the lunar soil is composed of oxygen, future explorers could extract it from the Moon dirt, and then mix it with hydrogen dropped off by previous unmanned rockets.
(Image Credit: Crystal Links- Lunar Mining)
Water can then be heavily filtered and recycled, allowing humanitiy to establish independent lunar outposts without the need of frequent supplies.
As a bonus, future settlers could use the spare hydrogen and oxygen to also create rocket fuel, which could help reduce the cost of missions elsewhere (whether it’s Mars, Ceres or even the moons of Jupiter).
Read MoreMars: A Paradise For Plants (But Not Animals And People?)
Update (12/23): Credited image (full of microscopic life) below.
Regardless of whether or not you believe that the red planet is the future of humanity, one thing is probably certain–whether it takes a decade or a millennium, humanity will probably settle upon that dusty crimson world.
If humanity ever does gain the necessary technology to terraform Mars into a habitable world (air pressure and temperature wise), we may discover that although the red planet makes an excellent habitat for terrestrial vegetation, it may make an extremely poor one for colonists and animals.
One of the key ingredients for animal life on our planet is oxygen. Without it, most creatures would experience a short (but painful) death, leaving the insects to rule the planet.
Thanks to the laws of photosynthesis, plants are able to produce a large enough volume of oxygen to enable animals, space geeks and people to thrive upon planet Earth.
Most of this oxygen however does not come from land plants, such as trees, grass, etc., but rather from a single celled organism called Phytoplankton which contributes between 70% and 90% of the worlds oxygen from the ocean.
Image Credit: Prof. Gordon T. Taylor, Stony Brook University, USA (via NOAA Photo Library)
While land plants do contribute their fare share of oxygen for our planetary survival, they may not be as effective on Mars which receives half the amount of sunlight as Earth (which could easily translate into less oxygen for our lungs).
Although Mars currently lacks large oceans like its bigger bluer brother, the red planet does contain an abundance of water that if melted could flood the planet.
While this may make it an ideal candidate to host Phytoplankton within Martian waters, it may not be a realistic scenario considering that the red planet could contain an abundance of perchlorate within its soil, which is deadly to most terrestrial life forms.
Image: Soil samples from “Snow White” trench, taken on July 8, 2008, were found to contain perchlorate after analysis in the Phoenix Mars Lander’s Wet Chemistry Laboratory. (Photo by NASA/JPL-Caltech/University of Arizona/Texas A&M University)
If Phytoplankton were to even survive within future Martian oceans, humanity would probably have to find some way to heavily filter out perchlorate from the soil in order to prevent it from contaminating the future “red” oceans of Mars.
Although these two dilemma’s may not be enough to discourage humanity from creating an eden out of this crimson world, the lack of a sizable moon may present a unique challenge for our rowdy species.
On Earth, the Moon (via gravitational tugging) helps our oceans distribute oxygen rich water to stagnant areas critical for some organisms to survive.
Image Credit: How Stuff Works.com
Without a strong gravitational pull future Martian oceans could eventually become stagnant overall, making it extremely difficult (if not impossible) for certain species to survive, which could limit which animals we could bring thanks to the circle of life.
Even though these three challenges may prevent humanity from turning Mars into a second Earth, it probably would not be enough to prevent the masses from settling this planet.
While large forests may be able to survive on the planet due to a (future) rich atmosphere of COs, humans may have to be content living within biospheres along with their animal friends (pets and pigs alike).
Read MoreAre Traditional Space Elevators The Wrong Way Up?
After being first envisioned by Konstantin Tsiolkovsky, then perfected by Yuri Artsutanov, Jerome Pearson and Brad Edwards, the space elevator has captured the imaginations of thousands of individuals who believe it’s humanities best hope for colonizing the solar system en masse.
This radical space concept led to the creation of two startups (LiftPort and Blackline Ascension), as well as support from NASA who (despite their skepticism) is offering $4 million in prize money towards successful teams/companies (thanks in part to their Centennial Challenge).
Despite the momentum that the space elevator community has built up over the years, their dreams of a 100,000 km “beanstalk” stretching into the heavens may not come to pass as the earliest plans for a structure coming into being hover around 2030.
Rather than spend decades perfecting carbon nanotubes and power climbers (key ingredients if a traditional space elevator is to become a reality), it may be better to focus on Skyhooks (aka orbital space elevators) instead.
Instead of grasping the Earth’s surface from either a seaport or a mountain top, a Skyhook would hover 150 km above our home world, giving it several advantages over its earth bound cousins.
While a traditional space elevator would require a massive counterweight at the end (i.e. an asteroid or a large space station), a Skyhook would only need a light counterweight at the top of the structure, which might be feasible with today’s technology (not to mention this economy as well).
A Skyhook would also be much shorter than their traditional brethren, spanning a length of no more than 4,000 km compared to 100,000 km for a traditional space elevator. Even if a Skyhook’s cable had to be fashioned from carbon nanotubes (which may not be needed as Kevlar and/or Spectra might be sufficient), it would be much easier to fashion due to its shorter length.
Last but not least, Skyhooks would probably not need to beam power to their transport climbers from below, a feat that may be extremely difficult for traditional space elevators (especially 100,000 km away!). Instead, climbers transporting cargo on a Skyhook could be powered by miniature nuclear reactors or via solar power from the rays of the sun.
Although Skyhook’s have a significant advantage over their earth bound friends, their Achilles heal lies in the fact one would need to construct a rocket/jet hybrid capable of “breathing air” when flying through our atmosphere, and later on switching to rocket engines when they reach the edge of space.
Fortunately the British are in the process of developing a new craft called Skylon (by Reaction Engines Limited) which may help remove that hurdle, making the construction of a Skyhook possible.
While space elevator enthusiasts may still opt to construct their terrestrial beanstalk in an attempt to link heaven and earth, it may be wiser to focus their efforts on Skyhooks instead–especially now that companies like Lockheed Martin may seriously pursue building a Skyhook which in the end could help open the final frontier to the masses.

One Solar Space Power To Rule Them All?
Image Credit: Loony Tunes
Note: Article inspired by NASA Watch, The Planetary Society and 21st Century Waves
Warning: This is an extremely long article, so you may want to grab a quick snack as you read through this post.
Anyone who has ever played board games such as Risk and Monopoly knows that the overall purpose of the game is for one player to dominant the board by either taking territory or securing financial resources ahead of their rivals.
The same rule also applies to the final frontier as evidenced by the space race emerging in Asia, as well as between the US and China.
While every nation probably has their own “road map” for conquering the final frontier, there are no less than five critical locations (ranging from asteroids to dwarf planets to even moons) that a space faring nation must secure if they desire to remain (or become) a solar space power in our star system.
First Stop: Luna
Orbiting a mere light second away from Earth, the Moon could easily be described as humanities second home due to its proximity towards our birth world.
Although the lunar surface may lack water (at least in abundance), its white regolith can be “easily” converted into breathable oxygen, allowing our species to survive beyond our earthen cradle without the need to constantly borrow air from our home world.
Often seen as free on planet Earth, oxygen in space will be literally worth its “weight” in gold, and any nation that can find a way to inexpensively produce lunar oxygen will have an advantage later on over its rivals (and may even be able to sell the precious gas for a profit).
While its oxygen rocks could enable humanity to live off world, its reduced gravity may make the tiny sphere appealing to asteroid miners seeking out near earth objects (aka NEO’s).
Since micro-gravity has a way of eroding bones and muscles, destroying immune systems, weakening hearts and strengthening deadly bacteria, asteroid miners may prefer to live lunar side (with frequent trips to mine these NEO’s), than to spend the majority of their time floating next to a space rock in micro-gravity.
Even though a space faring nation (both current and aspiring) could develop a sustainable presence around the Moon (and nearby space rocks) due to its resources and location, it may be wise to travel beyond Earth’s orbit towards more promising worlds (in order maintain its status a future space power).
Next Stop: The dwarf planet Ceres
Although some would consider it “insane” to skip the red planet, heading to Ceres first will ensure that a future space power has the resources to fund its expansion (note: despite the fact that doing so means sacrificing the prestige of sending the first man or woman to Mars).
Ceres strategically orbits within the metal rich region of the asteroid belt, making this dwarf planet prime real estate (at least to asteroid mining corporations).
Any nation establishing a colony on Ceres would be able to send teams of astronauts to secure nearby metallic space rocks as their own, potentially selling them to future allies or harvesting the mineral resources for themselves.
While the dwarf planet lacks any resources of its own, Ceres is suspected of hosting more “fresh water” than Earth itself, which would enable future asteroid minors to potentially grow their own food off world without depending on frequent supplies from Earth.
It would also allow Ceres to act as a interplanetary rest stop between Mars and Jupiter, not to mention a safe haven as well (just in case the asteroid belt becomes infested with space pirates).
Since most of humanities attention will probably be focused on Mars after the Moon, there will probably be very little competition establishing a dominant presence on Ceres (if not conquer it entirely for themselves).
Third Stop: The Martian moon called Phobos
Despite its popularity in science fiction, Mars will probably attract very few visitors due to the extreme difficulty in landing large payloads on the surface of the red planet.
Coupled with the fact that Mars lacks major resources of any kind (note: at least that we know of), the crimson world may only be inhabited by scientists, various cults and individuals disillusioned by Earthen (and Lunar) governments.
Even though the red planet may not be of much economic worth (at least initially), one of its asteroid moons Phobos could be converted into an enormous space station in order to make it easier to process metals harvested from the asteroid belt.
Since the sunlight on Mars is much stronger than in the asteroid belt, a future mining corporation could use the Sun’s rays to melt asteroid metals en mass before exporting them towards Earth (and Luna).
Although working on an asteroid moon may be profitable, living upon one may not due to the side effects of micro-gravity.
Even though a future miner could always counter the effects of micro-gravity with various drugs and electronic shocks, it may be wiser to settle upon the red deserts below as Mars’s gravity is approximately 38% Earth norm.
In order to reduce the cost of transporting personal (and equipment) to and from the Martian surface, a future space power may need to construct an “orbital space elevator“ on the near side of Phobos.
While constructing this would ultimately open up Mars to the rest of humanity (which a future space power could charge a fee for rivals to use), it would also allow them to import water from the Martian surface (instead of depending upon either Earth or Ceres for supplies).
Fourth Stop: The Jovian moon Callisto
Often regarded as a dead world, the Jovian moon Callisto may be of high worth to any space faring nation, due to the fact that it is one of the few radiation safe worlds in our star system.
Even though Mars and the Moon may have “celebrity status” throughout our solar system, neither of the worlds has a global magnetic field to protect their spheres from the wrath of the Sun.
Callisto on the other hand is not only protected by Jupiter’s magnetic field, but it orbits just beyond the gas giant’s radiation belt, enabling future colonists to raise families (and pets) upon this world without fear of growing a third eye ball.
While Callisto may not have any immediate value outside of being a midway point between the inner solar system and Saturn, establishing an outpost here would enable a future space power to “easily explore” its brother Ganymede.
Although Ganymede’s orbit takes it into the heart of Jupiter’s radiation belts, a properly shielded colony could use Ganymede’s global magnetic field to raise an abundance of crops with the help of bees (instead of relying upon ants who may not need a magnetic field to pollinate our green friends).
While it would probably be impossible for one space faring nation to conquer both of these worlds for themselves, conquering these moons early on (especially Callisto) could give a rising space power significant influence over the future of the Jupiteran system (not to mention the next gas giant as well).
Last Stop: The methane moon called Titan
Even if humanity finds a way to harvest the helium-3 locked away within Luna’s crust (not to mention the atmosphere of Uranus), the cost of mining it m
ay put it out of reach for most interplanetary commercial spacecraft.
Since supplies of Uranium and Plutonium could easily become unavailable for space travel (as many nations on Earth may need them for energy or defense), finding an inexpensive alternative could determine whether or not a space faring nation thrives or merely survives in the depths of our star system.
One way to guarantee that a future space power has the neccessary fuel to maintain its fleet (at least inexpensively) is to establish outposts near Titan’s methane lakes (which may contain an abundance of methane/ethane within them).
While it would not be surprising to see Titan heavily colonized in the fairly distant future (by various countries), securing this world early on would enable a space faring country to establish tremendous influence throughout the solar system (or at least within the ringed system of Saturn).
What about the other worlds?
Although their are plenty of other interesting worlds ranging from the burning crust of Mercury to the frozen wasteland of Neptune’s moon Triton, these worlds may not attract that much interest in the future (at least as far as we can tell right now).
Even though everyone probably hopes that humanity would put aside their differences and explore the final frontier in peace, six thousand years of recorded history seems to hold a dim view regarding this viewpoint (as one can glimpse the wars that have raged upon our planet).
Whether or not humanity decides to conquer every sphere and space rock within our solar system only time will tell.
But either way, these four worlds (plus one asteroid moon) may be the key that determines which space faring nation not only dominates our solar system, but perhaps guides us unto the next one as well.

Uranus: One Planetary System To Fuel Them All?
Orbiting almost 3 billion kilometers away from the Sun, Uranus is an ice giant that gathers little attention from the creatures that currently rule Earth.
Except for being used as the butt of astronomy jokes, the lopsided wonder gathers little press (if any at all), often being overlooked by both Saturn and Neptune.
Although the blueish-green giant may lack large lunar children like Titan and Triton (not to mention a set of dazzling rings), Uranus may be the key that enables humanity to not only conquer the outer limits of our own solar system, but perhaps enable us to reach the next one as well.
Even though Uranus contains a considerable amount of methane (located in the stratosphere), many scientists suspect that the cold ice giant may contain up to 16 trillion tons within its atmosphere, which may make it a prime target energy corporations (not to mention space faring nations of the future).
Often seen as the future of fusion power, Helium-3 could be the fuel that allows interstellar ships to trek through the dark void in between the star systems.
While scientists suspect an abundance of Helium-3 on the Moon, sifting through millions of tons of lunar regolith may not appeal to many people–especially as one would have to compete with other lunar businesses (like tourism) who may have other uses for the white “soil” beneath their feet.
Since claiming land (or atmosphere) on Uranus would be nearly impossible (unless one is able to set foot on the Uranian core), an orbiting space station would be free to collect the precious element, without the need to haggle neighbors with lawyers (or petition the government to take away property via eminent domain).
Despite its massive size when compared to Earth, Uranus’s gravity is only 89% Earth norm (at least at the top of the atmosphere) which means that humans may be able to create floating space stations within the atmosphere of Uranus, without the fear of being crushed by its gravitational forces.
Although other gas giants such as Jupiter and Saturn also have an abundance of helium-3, respectively, their deep gravity wells and strong winds would make mining the resource from the atmospheres incredibly dangerous (if not suicidal).
While Uranus’s heftier brother, Neptune would also be a potential source for helium-3, its violent winds may also dissuade would be helium minors from sending robotic probes beneath its icy blue clouds.
Uranus’s wind speeds on the other hand are a lot more tolerable, which may enable robotic probes (as well as future explorers) to travel beneath its clouds without the fear of being torn apart by Earth sized hurricanes.
Although it may be a century (or two) before we see humanity develop the technology (as well as the political will) to eventually reach this distant ice giant, it may not be surprising to see Uranus become the OPEC of the solar system, providing enough energy to not only keep lights on, but also to propel our species towards the next star system.

Melting Asteroid Metals With Martian Sunlight
(Hat Tip: Gizmodo and Dark Roasted Blend)
Whether or not we head to the asteroid belt before Mars, one thing is clear–while we may have the means to land upon and (hopefully) sift the metal from “the rubble” (or useless rocky material), we probably will be unable to inexpensively melt the metals on site.
Even though lasers are always an option, future colonists may not be too thrilled with using extra power to melt down the space metals, as that would only add to the overall cost of shipping the material elsewhere.
While some may be content to pass the cost onto the customer, it may be cheaper (and wiser) to ship the metals to the red planet in order to have the metals melted down via Martian sunlight.
Since Martian sunlight operates at half the strength of Earth’s, the solar furnace would probably have to be slightly altered to achieve the same strength as its bluer big brother.
Although some may suggest that the future asteroid mining industry could simply ship the metals to Earth, it may be wiser to divert the route towards Mars, as the red planet orbits about 100 million kilometers closer (at Aphelion) than Earth.
Martian colonists would also have the advantage of utilizing the crimson worlds two orbiting moons, allowing mining fleets to melt their metals upon either Phobos or Deimos without having to land on the Martian surface (which has a fairly steep gravity well).
Either way, Mars may play a critical role in our quest to colonize the solar system (which may make it a prime spot for future real estate).

Dogs: The Number One (Future) Solar Pet?
Image Credit: The Jetsons
(Image Credit: Mzelle Laure via Wikipedia)
Space is big. Its “vastly, hugely, mind-bogglingly big.” It can also be a lonely place as well.
Scientists have been previously warning that long term trips on the Moon (or towards Mars) may place undo psychological burdens on future astronauts, especially if they can not see Earth.
Since launching astronauts with their families may not be an ideal solution (although this would resolve the loneliness factor), it may be wise to include Fido in order to help combat the feelings of isolation off world.
While some countries may look to dogs as their next meal, in the west canines are often regarded “as man’s best friend.”
So whether you are known to befriend the canine (or are indifferent towards it), here are several reasons why this hairy beast may dominate our solar system (as the number one pet that is).
The Love Factor
Regardless of whether an astronaut is stationed on the outskirts of Callisto or observing the stars from Mars, living hundreds of millions of kilometers away from the home world can easily make one depressed.
A future colonist will probably feel frustrated with their commanders on Earth (for whatever reasons), and may have a similar attitude towards their crew mates–especially if they are confined to live within radiation safe houses for extended periods.
In order to help prevent cabin fever from breaking out off world, allowing dogs to accompany future colonists may be a wise idea, as most canines are known to show enthusiasm around the presence of their owners, which may help them feel appreciated millions of kilometers from home.
Although other animals may purr or even cuddle, dogs will often shout (or rather bark) their praises at seeing their owners again–a feat that somehow does not get old for our canine friends.
Superior Intelligence
(Image Credit: Ang on Aclaire.vox.com)
Many animals on our planet are known to boast measurable intelligence, but only one species seems to have the discipline to “master” digital technology.
(Suite 101) In a study at the University of Vienna in Austria, dogs used touch screen computers to show that they could categorize photographs. They were trained with treats to select a dog picture over a landscape picture. When they were shown a different set of dog and landscape pictures, they continued to select the dog pictures, demonstrating that they could apply earlier learning to a different situation. Researchers tested further by presenting the dogs with contradictory information to see if they were capable of forming concepts. When shown pictures of an empty landscape and a landscape with a dog, they continued to select the picture with the dog.
While this may seem like a non-factor to pet owners favoring other species, the fact that these canines can be trained to handle technical equipment may make them favorable pets when compared to their feline friends (and perhaps even pigs).
Safety And Security
(Image Credit: Kjetil via Wikipedia)
It does not matter whether one establishes large colonies upon Jupiter’s Ganymede or on the Sun baked world of Mercury, crime (however small) will always be a factor when establishing outposts on another world.
Since its likely that most colonies will probably reside within biodomes (assuming they are not underground altogether), which means using weapons slinging projectiles (i.e. guns) may not be a good idea, as punching too many holes in the walls could endanger the entire colony.
Even though one could always train the future colony’s security force in martial arts, it may be easier to use canines to help enforce the law.
Often seen as a major deterrent against crime, dogs can help off world security forces control raging crowds (in case the settlers ever decide to riot), as well as headbutt potential criminals (in order to avoid severely injuring the would be offender).
The Nose Knows
(Image Credit: Paul167 via Wikipedia)
Although a few worlds like Callisto and Titan may provide offer some relief from space radiation (from our Sun as well as beyond), many outposts will probably have to create portable magnetic shields to protect themselves above ground.
While artificial magnetic fields may enable us to survive off world, it may not provide full protection for future settlers which means that cancer rates on more radioactive worlds will probably be a lot higher than on Earth.
Since importing cancer detecting equipment to every facility (on every moon, planet and asteroid) may be extremely expensive, it may be easier to train (and deploy) dogs to sniff out the cancer instead.
(Nation Geographic) “Our study provides compelling evidence that cancers hidden beneath the skin can be detected simply by [dogs] examining the odors of a person’s breath,” said Michael McCulloch, who led the research. [...]
“Cancer cells emit different metabolic waste products than normal cells,” Broffman said. “The differences between these metabolic products are so great that they can be detected by a dog’s keen sense of smell, even in the early stages of disease.” [said Nicholas Broffman, executive director of the Pine Street Foundation.] [...]
By scent alone, the canines identified 55 lung and 31 breast cancer patients from those of 83 healthy humans.
The results of the study showed that the dogs could detect breast cancer and lung cancer between 88 and 97 percent of the time.
Using dogs to identify cancer within patients early can go a long ways to helping future doctors treat the disease and hopefully cure it as well.
Conclusion
While it would be silly to suggest that other species on Earth would not ultimately find themselves exported off world across the solar system (like pigs), the future may see the canine family accompany humanity not only throughout the outer reaches of our solar system, but perhaps into the next star system as well.

Will Geothermal Energy Power Our Solar System?
Image Credit: Apogee.net
Regardless whether one intends to dwell upon a dusty world, or an icy one, living on another planet, moon, or dwarf planet is going to require energy. Without a dependable power source, off world settlements will become nothing but fantasy, regulated to the imaginations of Star Wars, Star Trek and Serenity.
While a few worlds such as Mercury, Luna (aka the Moon) and Saturn’s Titan are blessed with an abundance of energy in the form of solar energy, helium-3 and methane-ethane lakes, respectively, most of the other spheres that dance around the sun (or their respective planets) seem to lack an ample supply of energy.
Without an lush supply of energy nearby, colonists living on other worlds will be forced to import energy from abroad, making these outposts not only expensive, but also small (as increased energy demand may make large cities unreasonable).
In order for our species to truly create independent colonies elsewhere, we may have to drill down beneath the soil in order to acquire the neccessary energy to power our future interplanetary cities.
Despite the fact that this technology is a little over a century old, geothermal energy has the potential to not only power our own home world, but the other globes that “roam” the vacuum of space as well.
For those unfamiliar with the technology, a geothermal power plant basically uses heat from the Earth’s core to turn water (or a “watery mix”) pumped from above into steam. This steam in turn spins the turbine engines, creating electricity for nearby communities to use.
A geothermal power plant can also pump up hot water trapped below, as in the case of the Calpine Corporation’s geyser power plant.
While the technology may not be as glamorous as solar power satellites, it does have the potential of fueling our energy dependent world.
While this technology is promising, one may wonder whether or not this technology would be feasible off world. After all, in order for geothermal power to have any relevance, it would have to reside on a world that is not only somewhat geologically active, but also contains water (or another liquid substitute) to turn the turbine engines.
Fortunately for our species, it seems that most of the worlds in our solar system seem to be blessed with both.
Mars
Upon first glance, the surface of the red planet appears to be (for lack of a better word) dead. While boasting the largest volcanoes in our solar system, the crimson globe apparently changes little, aside from a “global-cane” that covers the surface every six (earthen) years.
Despite its passive appearance, the Martian depths may be more active than we think beneath the surface, as evidenced by its semi-active core that seems to be generating a “lumpy magnetic field” that barely pops up above the surface (in some spots).
Mars also is known to host geysers in its southern pole, which may indicate that the red planet may a lot warmer underneath than we can imagine. Combined with the abundance of water, Mars may become fertile ground for future geothermal power plants.
Ganymede
With its parent world orbiting almost
780 million kilometers away from the Sun, solar power is not an option for any future colony settling on Jupiter’s largest moon.
Boasting a global magnetic field which is ironically three times larger than the planet Mercury, a future outpost on Ganymede may be a prime candidate for a geothermal plant.
While future “Jupiterans” would have to live within “aquarium houses” in order to survive the intense radiation surrounding the moon, their ability to “tap” into the Jovian moons center, providing enough energy to turn this frozen globe into a second Earth.
Saturn’s Icy Moons
Despite its size, the tiny ice world of Enceladus contains geysers that are spewing icy crystals above its surface.
While scientists remain baffled on how such a tiny world can contain a core warm enough to produce geysers on top, this tiny world could become a prime candidate for a geothermal power plant (by tapping into the “warm crevices” beneath).
But Enceladus is not the only ice world orbiting Saturn with geysers. Last year scientists discovered that both Tethys and Dione are also spewing ice particles into space, which may hint toward a warmer than anticipated core underneath.
Triton
Often known for its retrograde orbit around Neptune, Triton may become a major settlement in the future by harvesting helium-3 from the atmosphere of its paternal planet.
But before colonists can exploit the blue gas giant for profit, they will need to find a way to acquire energy upon that frozen world. Fortunately, Neptune’s “favorite son” does boast nitrogen geysers, whose erupting pressure may help keep an advance turbine engine spinning (thus keeping “the lights on” for a future colony.
Charon
While the debate rages on whether or not its “bigger brother” can join the planet club, scientists suspect that Pluto’s moon Charon may also have geysers on its surface, which could point towards a warmer core underneath.
Even though off world colonies will probably have to adjust their technology in order to make geothermal power plants feasible (perhaps by using the geyser pressure from the worlds to turn the turbine engines instead of simply using steam heat), future settlements may consider it more reasonable to power their cities from energy below, rather than importing it from afar.

Living Off World May Stink
Image Credit: Discovery Space
We are a unique species. We spend billions of dollars in order to launch satellites to orbit distant worlds (or rovers to explore across their surface) in order to bring back images of what the horizon may look like on another planet (or Moon).
Often, we imagine what it must be like to live on the red planet, or dance through the smog world of Titan, or even (if we are lucky) what it would be like to have a picnic on the Moon.
Unfortunately, our dreams of humanity expanding throughout our native star system may ultimately come to naught, due to the simple fact that living off world may irritate one of our key bodily members, also known as the nose.
Despite the romantic images off the dozens of worlds that dance around their paternal planets and stars, the reality is that many of these rocky spheres have unique odors to them, which may be encountered after a future settler returns to the outpost (after exploring the surface of their new home).
One prime example of this is the Moon, in which astronauts reported as smelling like gun powder after tracking in lunar dust from the outside.
Even though this scent may please those associated with the NRA, it may irritate would be lunar residents, convincing many that the view of the stars is not worth dealing with the smell of the lunar dust.
If one thought the smell of gun powder is bad, then they may have second thoughts about living on Mars after discovering that the red planet may actually smell like sulfur.
While many space scientists would probably be willing to deal with the stench in order to live upon a world hundreds of millions of kilometers away from our terrestrial home, most Earthen citizens may choose to simply skip even visiting the crimson planet, opting for a post card instead.
While these unique smells may not keep some people from abandoning Earth for a new orb to explore, it will (unfortunately) be more than enough to convince the vast majority to stay put on the home world.
Worse, it could also translate to more women avoiding living off world, since their sense of smell is usually greater than their masculine friends. After all, if women (en masse) decide that off world planets are not worth the “tribulation of the nose,” then the only large space settlements humanity may see will be penial colonies (as prisoners usually have very few rights–at least in most countries).
Since changing the aroma of extraterrestrial soils smells would be difficult (even if one were able to terraform it), it may be easier (and less expensive) to simply import air fresheners (or even scented candles where permitted) in order to mask the offending odors entering the space habitats.
While not every world humanity lands on will contain an unpleasant odor (that may make its way into the future outpost), we should do everything in our power to ensure that living off world long term is not only safe, but a pleasent experience for all five of our senses as well.

Moon Base Plus Amor Asteroids Equals Solar Powered Satellites?
(Note: Inspired by Ken Murphy of Out of the Cradle)
If extraterrestrials were (un)fortunate enough to visit our rowdy planet, they would realize that our civilization is powered by death. For our civilization to survive, to expand, and to literally keep the lights on our species must harvest the compressed liquid of billions of dead things–also known as fossil fuels.
While alternative energy sources such as solar, wind and “bio-fuel” do exist, they may not be enough to keep up with the future energy demand (hat tip: Life After the Oil Crash) of our ever growing population.
With energy supplies on Earth finite at best, some individuals have looked beyond the heavens above in order to satisfy our “energy cravings” below.
By simply constructing solar powered satellites (aka SPS) above our blue world, proponents argue that we would be able to not only meet energy demand, but hopefully create a greener environment at the same time.
(Video: A presentation to both Presidential Candidates of 2008 about the need to develop SPS for our planet).
Unfortunately one of the major obstacles to constructing an SPS is the cost of launching material into space, which may make an SPS unreasonable unless a space elevator is constructed (although by the time one is built, it may already be too late).
Since launching building material from Earth may be too expensive, our species may have to hunt for (and utilize) precious metals off world in order to reduce the cost of constructing these massive behemoths–which means future colonists may have to harvest not only lunar soil, but nearby asteroids as well.
Even though the Moon’s surface is composed of mostly oxygen, it also contains silicon, a key ingredient for producing solar cells.
While the Moon also contains other elements such as iron and aluminum (which could provide extra resources for constructing these massive solar panels), lunar colonists may prefer to harvest these elements elsewhere as both of these elements would have practical uses “lunar side” (iron for construction and aluminum for radiation shielding).
Instead of scouring the lunar surface in search of extra building material, humanity instead may choose to harvest nearby space rocks orbiting between our homeworld and the red planet–also known as Amor asteroids.
Unlike the asteroids located in the main belt, Amor asteroids orbit much closer towards Earth, with many of them traveling around in stable orbits.
While their proximity towards our Earthen cradle may make them attractive for scientists, its their abundance of minerals and metals that may make them priceless for space minors.
One Amor asteroid in particular, 433 Eros may have enough precious metals within its tiny frame to be worth trillions of dollars (which should provide more than enough material to construct several SPS’s in space–with cash to spare for financing the project as well).
Even though there are still many challenges to building an SPS (not to mention where to locate the rectenna), our species may have to wait until we begin to harvest our “local neighborhood” before we have enough funds to actually create these energy wonders (without bankrupting our civilization).

Welcome To Venus (Your Interplanetary Way Station)
(Inspired by Nancy Atkinson of Universe Today)
Venus, a world shrouded in dense clouds of sulfuric acid holds little promise of ever hosting future settlers.
Once thought to harbor a dense jungle underneath its “steamy atmosphere,” Venus is now known to be an inhospitable world due to its crushing atmosphere and deadly climate.
Even though living upon the planet may be impossible (if not impractical), Venus may have a significant purpose for future space travelers beyond using the barren world as a convenient garbage dump.
Orbiting the sun at approximately 108 million kilometers, a space station orbiting Venus would have the opportunity to help resupply traveling shuttles, rocket ships, etc., braving the vaccum of space.
This would help not only cut down the cost of traveling to Mercury, but time as well (since spacecraft could always use the planet as a sling shot towards Mercury or Earth).
Since these future space stations would probably serve as interplanetary rest stops, they would probably have to be built with artificial gravity in mind, lest colonists suffer the side effects of micro gravity.
While Venus will unlikely boast a large population when compared to Mars, Ganymede and Callisto, its economy may rival that of its more “fertile” siblings orbiting the Sun.

Solar Bamboo Forests
Image Credit: China Daily BBS
(Note: Inspired by Ian O’Neill of AstroEngine, Image Credit: Paul Vlaar)
If one were able to measure the breadth of our solar system from the surface of the Sun to the distant orbit of Pluto, it would measure approximately 7 billion kilometers (or just under 50 Astronomical units).
While most of these worlds will probably be inhabited sparsely, some of the larger worlds in our solar system will probably be home to tens of millions (if not billions) of colonists, not to mention “zillions” of plants and animals.
Whether future residents choose to terraform their global habitats, or reside within biospheres instead, they will probably need a way to import some organic beauty and insert it upon their barren new homes.
Even though future settlers could simply grow a few flowers or bushes, they may choose to raise a forest in order to mimic life upon their Earthen cradle. Since many trees take decades to reach maturity, future colonists may opt to grow bamboo forests instead.
Sometimes seen as a pest in the west, bamboo is highly respected within Eastern cultures, which may have something to do with bamboos unique ability to grow very fast, ranging from 30 centimeters a day to (in one case) over four feet in 24 hours.
Their fast growth rate would make it easy for settlers to establish dense forests within a year (or two), making these outposts more appealing to not only families, but scientists needing a break from “all things metal.”
While their fast growth and beauty may appeal to the artist, the bamboo’s practicality may appeal to the pragmatist.
Despite the fact that other trees may grow thicker (and sometimes higher) than bamboo, very few (if any) can match the amount of oxygen generated by this eastern tree.
(Image Credit: Environmental Bamboo Foundation)
Bamboos are known to produce 35% more oxygen than their tree companions, as well as absorb more CO2.
If included within future space habitats, these fast growing trees could help reduce the cost of living away from Earth, as settlers would not have to import as much oxygen from Earth or the Moon.
Although off world inhabitants will probably view metal as the primary building material for outside the outpost, bamboo wood may prove to be an excellent source for building material within space colonies.
Often known for its “strength and toughness” (at least with some species), bamboo could enable settlers to build furniture (such as chairs, desks and tables), eliminating the need for importing these items from Earth (which can be quite expensive).
If building furniture appeals to the future solar craftsman, then eating bamboo shoots may appeal to the stomach.
(Image: Bamboo shoots (or sprouts) at a Japanese Supermarket. Credit: Chris 73 via Wikipedia)
Despite the fact that most bamboo species would be considered toxic to ones health, there is at least one species that may provide a source of nourishment for future settlers.
Since most worlds orbiting our star system lack a global magnetic field, scientist would have to depend upon ants to pollinate the flowers of these future bamboo forests, not to mention provide plenty of water for them to drink.
While it would not be surprising to see colonists importing (and planting) other trees upon worlds like Mars, Ganymede and Callisto, it may not be an uncommon sight to behold thousands of bamboo forests upon dozens of solar worlds.
Update: Edited a few words for grammar and clarity.

Mercury Before Mars Equals Space Faring Civilization?
Orbiting a little over one light second away from the surface of Earth, the Moon is an obvious choice in our quest to revisit the stars.
Harboring helium-3 withing its crust, the Moon could help “jump start” our journey into the cosmos financially, if not pay for itself by selling future space stations oxygen via its lunar rocks.
Even though the Moon may benefit our species tremendously, visiting Mars may be harder to justify economically.
For corporations, stock holders may not see the value in visiting the red planet for short term gains (or profits). Meanwhile tax payers may grumble at politicians spending money on another world without seeing any immediate benefits towards Earth.
Such a scenario could easily lead towards humanity delaying (or even skipping) Mars, opting instead to visit the asteroid belt in order to harvest its precious metals.
While mining the asteroid belt would benefit humanity financially, it may not motivate our species to choose a second home en mass outside of the gravitational influence of Earth.
In order to justify Mars, our species may have to look towards the first “rock” from the sun, Mercury.
Described by some as “A Mini-Earth in Moon’s Clothing,” the planet Mercury shares a few similarities with Earth’s Moon.
Orbiting “recklessly close” towards the surface of the Sun, solar energy on Mercury is about 6 1/2 times greater than that on the Moon (or Earth), making the world a prime location for solar powered satellites.
Its close proximity towards the Sun has a few scientists predicting that its crust may be loaded with helium-3, which would make it an ideal “next step” after humanity is done depleting reserves on the Moon.
Mercury may also have an abundance of metals within its crust as well, which could make it an attractive location for future mining corporations (who may consider asteroid mining too dangerous for their employees).
Despite the fact that this world has a global magnetic field, this sun baked world may not attract a large population due to the fact that it lacks an abundance of water.
While lunar colonists would probably be able to import water from Earth, Mercurian settlers may have to look elsewhere as Earthen gravity could make importing water (not to mention food) from the homeworld very expensive.
Since Mars has an abundance of water (in the form of ice), future Mercurian corporations could easily contract explorers to filter and export this precious liquid “sun-ward,” launching a whole new industry on Mars.
This could make Mars economically attractive to future Earthlings, who may consider settling the planet en mass in order to reap the benefits of interplanetary trade.
This ultimately could help push our species towards other promising worlds (such as Callisto, Ganymede and Titan), enabling our species to become a space faring civilization.

Conquering The Frozen Frontier (Kuiper Belt Objects)
(Image: Size comparison between largest Kuiper Belt Objects, sometimes called Trans-Neptunians, against Earth. Credit: NASA)
Whether it takes 50 years–or five thousand–humanity seems destined to expand beyond their earthen cradle and conquer the solar neighborhood around them.
Our species may in the distant future find ourselves settling on worlds ranging from the burning crust of Mercury, to the desert world of Mars. From conquering our own lunar body towards colonizing other moon worlds such as Ganymede, Callisto and Titan.
We may even venture as far as settling upon Neptune’s Triton, but beyond that humanity may see little incentive on settling beyond the classical eight planets (sorry Pluto).
While some may see little value of going beyond the gas giants, they may not realize that the Kuiper Belt, located on the “outer frozen edges” of our solar system may play a vital role for humanity–especially if we become an interstellar species.
Imagine if you will you are traveling on a star ship heading towards Alpha Centauri from the Epsilon Eridani star system. You need to make a pit stop in order to not only pick up a few supplies, but to also power down your craft in order to fix a few engines that keep creating a weird pining sound.
If you were the captain of that interstellar vessel, would you rather take your ship deep inside the Sol star’s gravity field, or would it make more sense to dock near a Kuiper Belt object located between 30 and 50 astronomical units away?
Unless a star ship desired to take a tour of the solar system it would probably be wiser if humanity established trade settlements upon these frozen worlds in order to help space craft traveling between the stars refuel (or repair) before heading towards another star system.
Since trade upon a Kuiper Belt Object would probably be sparse at best (considering the enormous distances between nearby stars), their main inhabitants will most likely be astronomers and astrophysicists (with space entrepreneurs probably in the minority).
Located far way from the major worlds that dance around our sun, the Kuiper Belt objects would find little appeal among the vast majority of people, who would probably prefer living upon a world with “some scenery” (i.e. an atmosphere or gas planet in the sky).
This would provide many scientists (such as radio astronomers) with the necessary isolation needed to conduct observations of the universe without great interference from radio noise and light pollution beaming from solar colonies.
Scientists could also conduct experiments that might be considered “too dangerous,” to be carried out upon other worlds, with little fear of contaminating everybody else living nearby.
Last but not least Kuiper Belt objects may be of use to military bases in order to ward off future threats. Creating military outposts upon these distant worlds may help establish a perimeter around our star system, which could act as a first line of defense against invasive fleets from another star system (whether they be human, robotic or God-forbid “something else”).
While the bulk of humanity will probably reside within the classical eight planets, it may not be surprising to see our species placing our fingerprints upon these frosty worlds in order to spread our presence from the inner system towards its frozen edges.
