Discussing reasonable ways to colonize our solar system

Another Reason Martian Settlers May Choose Solar Over Nuclear Power

Posted by on Oct 11, 2011 in Energy, Mars, Technology, Video | 1 comment

Even though having a mini-nuclear reactor nearby is not a bad idea, settlers upon Mars may prefer an option that relies less upon the splitting of the atom and more upon the rays of the Sun.

Scientists in Spain have figured out a way for solar power stations to generate energy after sun set when rays from the Sol star are no where to be found.

Gemasolar, the concentrated solar power plant located in Fuentes de Andalucía (Seville), a property of Torresol Energy (a joint venture between Masdar – Abu Dhabi’s future energy and clean technology company and SENER – the leading Spanish engineering and construction company) has supplied its first uninterrupted day of electricity to the network.

This has been made possible by its innovative technique of storing solar energy in molten salt, a cutting-edge thermal-transfer technology developed by SENER. This system is capable of fifteen hours of electricity production without solar radiation which overcomes fluctuations in the energy supply. [...]

The salt storage system allows the plant to stretch its electrical production hours to beyond sunset, regardless of the cloud cover. Thus, Gemasolar, with its 19.9 MW steam turbine, is able to supply electricity to a population of 25,000 households.

Eventually the plant will be able to supply 24hrs of uninterrupted production per day on most summer days, providing a higher annual capacity factor than most baseload plants such as nuclear power plants. (Torresol Energy

Although Martian settlers will probably need a mini-nuclear plant as a backup energy source (as Martian hurricanes have a habit of blocking out the Sun worldwide), relying upon a solar-thermal hybrid could enable colonies to thrive upon Mars without having to rely upon infrequent shipments of nuclear plants from Earth.

This technology would also benefit asteroid colonies as well, as it would enable settlements within the inner solar system to become less dependent upon Earth (or even Mars) for resources.

Note: Since sunlight intensity tapers off beyond Mars, solar power (of any kind) would be useless for out posts established upon Jupiter’s mega moons (Callisto and Ganymede), who would need to rely upon nuclear energy to avoid freezing to death.

Experience Martian Gravity Without Leaving Earth?

Posted by on Oct 3, 2011 in Mars, NASA, Video | 0 comments

[vimeo http://vimeo.com/23024940 w=500]

For those of you who are Mars-bound, Adam Norton has developed a clever way of simulating reduced gravity without having to visit the red planet.

Mars Gravity Simulator is a fully functioning experiment adapted from the design of Apollo- era lunar gravity simulators, but made for Martian conditions. It can be used to assess maneuverability of Astronauts at a gravity approximately 40% Earth gravity, as well as to study gait changes for those conditions. Lunar locomotion styles from the Apollo landings were tested for speed and efficiency as well as to establish a figure for the approximate change in the walk/run transition speed at Mars gravity. (Adam Norton / Performance Space)

As you can see from the video above, this is actually an ingenious way to train future explorers intent upon settling Mars on how to “trot” upon the crimson world’s surface.

Norton’s adapted design is inexpensive enough (at least relatively speaking) to be adapted by the public as well as the private sector, not to mention private citizens seeking to envision themselves living off world.

Note: Since Martian gravity is almost 2/5 Earth norm, future residents could probably forsake wearing gravity suits (unless they plan on making a return trip to Earth in near future).

Heartache: Cosmic Radiation May Crimp Off World Adventures

Posted by on Apr 11, 2011 in Health, Video | 0 comments

Space travel could be bad for astronauts’ arteries from uabnews on Vimeo.

As glorious as it would be to embrace the heavens above and set foot upon extra terrestrial soils, we need to face the reality that space is not for the faint of heart–this time quite literally.

A study by the University of Alabama at Birmingham (or UAB for short) has presented another danger regarding space radiation which may cause a few people to scratch themselves off the list.

Using an animal model, researchers assessed the affect of iron ion radiation commonly found in outer space to see if exposures promoted the development of atherosclerosis, as terrestrial sources of radiation are known to do. They observed that cosmic radiation accelerated the development of atherosclerosis, independent of the cholesterol levels or circulating white blood cells of the mice. It also worsened existing atherosclerotic lesions. [...]

[...] Kucik and his colleagues examined atherosclerosis development in mice following targeted exposure to a particle beam of high-velocity iron ions — similar to those found in space — produced by scientists at Brookhaven National Laboratory in New York. [...]

“At 13 weeks it was surprising and quite remarkable that we already could see permanent damage — an irreversible thickening of the artery wall where it had been exposed to radiation,” said co-author Janusz Kabarowski, Ph.D., assistant professor in the UAB Department of Microbiology. “The irradiation had no significant effect on the frequency of circulating immune and inflammatory white blood cells or plasma lipid profile.” (UAB News)

Although this isn’t a show stopper for future space travelers, it does mean that until we can develop artificial magnetic fields strong enough to repel cosmic radiation if we want to see our species survive off world (at least upon the surface).

Since space colonists will inevitably be exposed to cosmic radiation at some point in their lives (especially if they are traversing between the planets), it might also be a good idea to clone a few extra hearts (or harvest them from pigs) just in case the originals become damaged beyond repair.

Extraterrestrial Farmers To Raise Grain Without Soil? (Aeroponics)

Posted by on Dec 7, 2010 in NASA, Space Food, Video | 1 comment

If you were to attempt to raise a garden utilizing only lunar or Martian soil, chances are that your precious plants would either die a horrible death or survive albeit malnourished.

While there are probably exceptions to this rule (i.e. asparagus might be able to thrive within Martian dirt), the vast majority of terrestrial plants will need terrestrial soil in order to thrive, which poses a huge problem for humanity (as people need to eat off world, let alone find employment).

Instead of importing tons of terrestrial soil from the homeworld or manufacturing large quantities from humans, it’s probably wiser to raise them without soil thanks to aeroponics.

Growing plants without any soil may conjure up images from a Star Trek movie, but it’s hardly science fiction. Aeroponics, as one soilless cultivation process is called, grows plants in an air or mist environment with no soil and very little water. Scientists have been experimenting with the method since the early 1940s, and aeroponics systems have been in use on a commercial basis since 1983.

“Who says that soil is a precondition for agriculture?” asked Graber. “There are two major preconditions for agriculture, the first being water and the second being plant nutrients. Modern agriculture makes extensive use of ‘soilless growing media,’ which can include many varied solid substrates.”

In 1997, NASA teamed up with AgriHouse and BioServe Space Technologies to design an experiment to test a soilless plant-growth system on board the Mir Space Station. NASA was particularly interested in this technology because of its low water requirement. Using this method to grow plants in space would reduce the amount of water that needs to be carried during a flight, which in turn decreases the payload. Aeroponically-grown crops also can be a source of oxygen and drinking water for space crews. (Astrobiology Magazine)

Using Aeroponics would not only reduce the overall cost of raising grain, but enable us to establish “self sustaining” colonies beyond the Jovain lunar worlds (such as Callisto, Ganymede and Saturn’s Titan), but also upon asteroids and Centaurs (aka giant comets like Chiron) as well.

While aeroponics would not be feasible for every time of plant available (i.e. raising forests would require tons of soil), it would make it easier to settle upon the worlds that dance around our yellow sun which would aid humanities quest to conquer the final frontier.

Video: Inflatable "Tents" For Off World Settlers?

Posted by on Sep 7, 2010 in NASA, Technology, Video | 0 comments

(Image Credit: Bigelow Aerospace)

For those of you who envisioned outposts made out of metal, plastic and off world dirt, you may soon be disappointed that NASA and ESA have a different vision for conquering the final frontier, one filled with lots of hot air.

Gary Spexarth, manager of lunar surface systems design at NASA, believes that, despite their appearance, current inflatable habitats are far better suited than metal structures to the harsh environments of space. ’You could think of these inflatable modules as a big spacesuit,’ he said. ’The fabric is extremely tough and durable, but also designed to be as lightweight as possible. Unlike rigid metallic structures that can shatter or bend if hit by a micrometeorite, flexible material is able to recover to a certain extent.’ [...]

A promising candidate is US company Bigelow Aerospace, which was founded by real-estate tycoon Bob Bigelow to develop inflatable extensions for the ISS. In 2004, Bigelow acquired the licences to NASA’s Transhab programme and has since successfully launched the Genesis I and II inflatable test craft. It now hopes to launch an 180m3 spacecraft called the Sundancer while looking at the possibilities of creating an inflatable Moon base. Bigelow’s work has far exceeded what others have been able to achieve in the field, largely thanks to the massive amounts of private funding. The company also recently announced that it is working with Boeing on the development of a commercial space-station system. (The Engineer)

Although inflatable structures have their own challenges (mainly dealing with the issue of folding them properly), deploying them upon the surface of the Moon, Mars, etc. is wiser than attempting to build settlements directly from extraterrestrial soil.

NASA has previously announced their intentions on using inflatable outposts for space as well as on the Moon, although they have yet to materialize thanks to the political makeup of Congress.

Currently Bigelow Aerospace is leading the front with its inflatable space stations, and with NASA stuck in budget limbo (due to Congress’s opposition to Obama’s first vision for space) we may have to rely upon Bigelow to establish beachheads upon the Moon.

Video: Humanity Vs Space Radiation

Posted by on Sep 6, 2010 in Health, Video | 0 comments

Aside from government politics, space radiation is one of the biggest threats to humans seeking to leave our home world.

Unless we find a way to protect ourselves, humanity will only be able to settle upon only a few worlds within our star system.

As shown in the video below, scientists are attempting to find innovative ways to counteract radiation’s effects, as failure to do so can result in a few dead astronauts.

Scientists are currently working on ways to deal with radiation via medicine, nano particles and portable magnetic fields, as well as mapping out “safe havens” (i.e. off world caves on the Moon and Mars).

Thus far our closest neighbor has some temporary protection thanks to Earth’s magnetic field, although hopefully we can come up with a more permanent solution aside from just settling Jupiter’s Callisto and Saturn’s Titan.

India Delays Human Space Launch

Posted by on Jun 14, 2010 in Blog, India, Space Race, Video | 0 comments

After promising the world that India would become a space power by 2015, it looks as if the world’s largest democracy is now scheduling its first human encounter with the stars by 2017.

India has aspirations to establish a lunar colony in the future as well, and has even proposed teaming up with Japan as well as Russia to help achieve their space goals.

Hopefully the land of a billion people will be able to to meet its timeline within seven years, as any further delay could result in India ceding dominance to China (who currently reigns as the space king in the east).

Keeping Recycled Space Water Clean (Via Ultraviolet Light)

Posted by on May 12, 2010 in Blog, Health, Technology, Video | 0 comments

Unless you are fortunate enough to live on a water abundant world (like Earth, the red planet, and yes, even the Moon), future space travelers are going to have to recycle every drop of water that exits their body (regardless of origin).

Since bacteria have a tendency to thrive in micro gravity, astronauts will need to find a way to kill off these microscopic creatures before they kill us off via recycled sweat and other bodily fluids (especially since our immune system becomes weaker in zero-G).

Fortunately for us a company may have a quick solution that is not only effective but inexpensive as well.

(Homedics, note: PDF file) UVC [ultraviolet C] light, with wavelengths between 100 and 280 nm, is commonly referred to as “germicidal light” due to its effectiveness in destroying microorganisms. UVC light acts as a natural outdoor air purification system by deactivating the DNA of microorganisms and destroying their ability to multiply. [...]

Utilizing the germ-killing benefits of UVC light, HoMedics, the leader in health and wellness products, developed Restore®, a complete water purification system in an easy to use pitcher. Restore combines UV Clean technology to remove bacteria, viruses and microbial cysts with a filtration system to reduce heavy metals, chlorine (taste and odor), and some industrial and agricultural pollutants.

Although this technology could also be used for off world settlers (who may have to drink recycled water until they can melt enough space ice), this technology would also benefit residents of orbital space stations around Earth, Venus or even a gas giant.

It could also help reduce the overall cost of filtering space water, allowing corporations and governments alike to invest money into other area’s (like propulsion or food).

Video: VASIMR May Be The Only (Safe) Way To Reach Mars

Posted by on Mar 22, 2010 in Blog, Mars, Solar Essay, Technology, Video | 2 comments

(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.

According to Senator Bill Nelson, President Barack Obama wants NASA to change course and instead prepare itself for a close encounter of the red planet.

Visit msnbc.com for breaking news, world news, and news about the economy

While this news should cheer Martian fans, it is doubtful that Obama or Nelson will be able to convince the public that a Mars mission is possible (especially during a recession).

Hopefully Nelson or Obama can provide more details as to how we will go about funding a Mars mission (outside of sending more robots that is), otherwise we can safely rule out ever seeing a man or woman creating crimson foot prints off world–at least not from America.

Video: Will Nuclear Rockets Help Russia Beat America And China To The Stars?

Russia, a nation nation known for putting the first satellite, man, woman, dog, etc. into space (not to mention being the first to pioneer space tourism with Space Adventures) may embrace nuclear rockets to help them reach the stars (and perhaps even Mars as well).

While a nuclear rocket from a practical stand point makes sense (as they can lift heavier objects to orbit compared to their chemical cousins), it would probably also isolate Russia (since anything nuclear is often frowned upon–at least in the west).

It may also help Russia catch up to America (or rather the private sector) as well as maintain their lead against China, whose presence is motivating everyone to claim a piece of Luna for their own.

Off World Colonies Will Have Organ Labs (But No Organ Donors)

One of the beauties of living on planet Earth is that if you ever have an organ fail, you can easily sign up for a new one before the rest of your body expires (well, at least you can in China).

However if one lives upon say Mars, the dwarf world Ceres or the Galilean mega moons of Ganymede and Callisto, your options of finding a suitable match may be close to zero.

Instead of waiting for suitable donor organ from Earth, it may be more practical for off world settlers to grow their own instead.

(Gizmodo) Laboratory-grown organs and tissues are already benefiting patients today. For example, laboratory-grown bladders are being tested in children with spina bifida and adults with spinal cord injuries and will soon be tested in patients with bladder cancer. Tissue engineering technology has been used to repair narrowed urethras, the tube that empties urine from the body.

The Wake Forest Institute for Regenerative Medicine has already made great strides in producing functioning organs which will potentially benefit millions of individuals on Earth.

Led by Anthony Atala, this medical technology could have the potential of affecting millions of future settlers across our star system, enabling them to live with greater independence from our home world.

Almost Star Trek: EBF3 Tech Could Help "Replicate" Tools For Lunar Settlers

Posted by on Nov 5, 2009 in Blog, Moon, NASA, Technology, Video | 1 comment



Even though Star Trek replicators are still a few centuries away, it looks like a device called the Electron Beam Freeform Fabrication (or EBF3 for short) could help future lunar colonists create the tools they need on site without having to radio Earth for supplies.

(NASA) Electron beam freeform fabrication (EBF3) is an emerging cross-cutting technology for producing structural metal parts that has been developed by researchers at Langley over the past four years. The EBF3 process uses a focused electron beam in a vacuum environment to create a molten pool on a metallic substrate. The beam is translated with respect to the surface of the substrate while metal wire is fed into the pool. A part is thus built directly from a computer file in a layer-additive fashion. This process has gained interest in the Exploration community for the astronauts to fabricate structural spare parts and new tools during long duration human exploration missions. DARPA has also expressed interest in EBF3 as a manufacturing process that could be used for building large space structures on-orbit.

Despite appearing on MSNBC, this NASA seems to have released info regarding this technology last May, although it seems to have received very little attention.

What makes this significant is that lunar settlers can use the technology to help create spare parts for their vehicles and off world habitats (since the moon dirt is rich in minerals and metals).

Video: What Recession? Galactic Suite To Build Space Hotel In 2012

Posted by on Nov 5, 2009 in Blog, Space Industry, Space Tourism, Video | 0 comments



With the global recession forcing people and businesses alike to reduce spending, it looks like one space company is set on establishing a presence in the heavens above, come what may.

(Reuters) A company behind plans to open the first hotel in space says it is on target to accept its first paying guests in 2012 despite critics questioning the investment and time frame for the multi-billion dollar project.

The Barcelona-based architects of The Galactic Suite Space Resort say it will cost $4.4 million for a three-night stay at the hotel, with this price including an eight-week training course on a tropical island.

Despite arriving upon the scene more than a few years ago, Galactic Suite has already secured 43 clients which translates to $184,900,000 in business (assuming each client was charged the current fare).

They also boast the backing of an anonymous billionaire, who seems to have pledged around $3 billion in order to finance this endeavor.

While Galactic Suite has yet to launch anything into space (unlike their rival Bigelow Aerospace which has launched two space habitats already), their successful entrance to the stars could help revolutionize the entire space industry–if not our planet as well.

Although microgravity is not exactly the greatest place to sustain an injury (unless you are a dangerous microbe), many scientists are exploring new ways of conducting surgery in a weightless environment.

While a space doctor will be needed to help mend the wounds of astronauts, they may choose to use lasers to seal the wound instead of medical stitches.



Since regular earthly stitches are composed of synthetic material and catgut, scientists may prefer using lasers as it would translate into one less item to pack (as well as one less requirement for a future space doctor).

To Fund Or Not To Fund: A Stimulus For SpaceX? (Video)

Posted by on Feb 11, 2009 in Blog, NASA, Politics, Space Industry, Video | 1 comment

(Image: Falcon 9/Dragon configured for cargo delivery to the ISS. Credit: SpaceX)

With Congress wresting over the bailout stimulus package, it looks as if SpaceX (who launched their first successful rocket last year) is asking the public to contact their state representatives in order lobby for additional funding for COTS-d (aka the Constellation Orbital Transportation Services).

(SpaceX) What this would mean for taxpayers and high tech jobs in the United States is very significant. Let’s consider the default plan under way, which expects that our country will use the Russian Soyuz at the currently negotiated price of $47 million per seat for the period between Shuttle retirement (2010) and Ares/Orion reaching Space Station (2016). Even assuming that we drop the number of US astronauts going to Station from the current 30 per year with Shuttle down to 14 per year, the cost will be approximately $3.3 billion. However, there is also a human cost in the thousands of jobs that the money could have supported back home.

In contrast, F9/Dragon would cost less than $20M per seat and it is 100% manufactured and launched in the United States. We are estimating that it would create well in excess of a 1000 high quality jobs at Cape Canaveral and an equivalent number in California and Texas, where we do our manufacturing and testing. Moreover, the total cost would only be $1.5B, so taxpayers would save nearly $2B. [...]

COTS Capability D can be completed within two years from date of funds receipt. In fact, with a little extra money and some modifications to the plan, it can be accelerated even further.

Since COTS Capability D is an existing option in an already competed contract, NASA could exercise it right away, resulting in immediate job creation. [...]

If you think this makes sense, please contact your representatives in the House and Senate, as well as Rep. Mollohan and Senator Mikulski who lead the Commerce, Justice and Science Appropriations Subcommittees. Please encourage them to fund NASA Exploration in the Stimulus Bill and provide the $300M in funding necessary to begin COTS Capability D.

While the public may not be a fan of spending even more tax dollars for the private sector (note: this author is not), Congress should probably fund the COTS-d program (as outsourcing to Russia does not sound like a great idea).

SpaceX has even provided a video, in order to help inspire Americans to support a home grown NewSpace company.

Video: Hope Or Hype? Travel To Mars In Just 3 Days?

Posted by on Jan 19, 2009 in Blog, Energy, Mars, Technology, Video | 4 comments

(Hat Tip: Spaceports)

Although our species has mastered the art of landing rovers upon the Martian surface, we have yet to develop a fast way to transport astronauts from Earth to Mars (assuming we can figure out how to safely land humans upon the crimson soil).

While some “feasible” technology may be able to shorten the overall trip to under 40 days, Moacir L. Ferreira Jr. is proposing that a rocket could potentially do it within 72 hours with the help of his CrossFire Fusor reactor.

(CrossFire Fusor) The CrossFire Fusor relies on magnetic fields for confining radially charged particles and relies on electric fields for trapping longitudinally them. It also relies on electric fields for accelerating the charged particles for reaching great kinetic energy of about 600KeV (7 billion°C) at inexpressive energy consumption.

The CrossFire Fusor is the first nuclear fusion reactor designed for achieving a true three-dimensional confinement plus a three-dimensional charged particles injection, and for having an adequate escape mechanism for the charged products of nuclear fusion thrusting a spacecraft. It also is the first, among the non-neutral plasma reactors, that can confine a plasma in a quasi-neutral state solving the saturation problem.

The CrossFire Fusor also is the first designed for having great flexibility for confining and fusing charged particles comprising positive and negative ions from neutronic and aneutronic fuels. The nuclear fusion fuel can be composed of several light atomic nuclei like hydrogen, deuterium, tritium, helium, lithium, beryllium, boron, in special boron hydrides and helium-3.

The CrossFire Fusor also is the first providing a method for converting energy of charged products from aneutronic nuclear fusion directly to electricity by neutralization process, that can reach an efficiency exceeding 95%, and it is the first to present a power supply system with a concept of multidirectional energy flow.

While the technology itself looks promising, we may not see this type of rocket available until 2020 (as nuclear fusion has yet to be perfected).

Either way, if Ferreira’s reactor is not used for interplanetary travel to Mars, it may have a future in keeping the lights on for future settlers of Ganymede, Callisto and beyond.

Melting Asteroid Metals With Martian Sunlight

Posted by on Oct 29, 2008 in Asteroids, Blog, Mars, Solar Essay, Video | 1 comment

(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).
