The "cantaloupe terrain" seems to indicate extensive cryovolcanic activity and the apparently youthful surface seems to imply that Triton has a lot of internal warming happening for some, as yet, unknown reason. Perhaps that indicates a relatively shallow sub-surface ocean? Piping up high-pressure water from down below might be a good way to warm the colony.<BR/>I've always liked Triton, alongside Titan, but the signs for shallow internal oceans on Titan are obscure to non-existent. Triton, paradoxically, might be one of the warmest outer planet moons - if we but scratch its icy crust.qraalhttp://www.blogger.com/profile/13436948899560519608noreply@blogger.com
