Space colonisation – Ceres first, Mars second?

The dwarf planet Ceres An interesting post over at Colony Worlds suggests that the dwarf planet of Ceres would be a better bet for early human colonisation than Mars – it has supplies of water ice and valuable minerals, but a far shallower gravity well, making it a more viable proposition from logistical and economic perspectives. Personally, I think getting a few working orbital colonies around our home planet would be a sound first move … but after that, why not? [Image from Wikipedia]

Martian Water Saga, Part [x+1]: it’s back on again! Maybe.

mars_icy Long term readers of Futurismic will know well my frustration with the constant see-sawing of scientists over the "is Mars wet?" issue, and I’m going to spare relative newcomers the weight of my angst.

Instead, I’ll just point to a story that reports on analysis done at MIT which suggests the southern polar ice cap of Mars may actually be water and not ‘dry ice’ … and to another, dated just a few days ago, which says images from the Mars Reconnaissance Orbiter seem to indicate that certain topographical features of the Red Planet may not have been carved by water as previously suspected … although the results "don’t confirm or deny" the theory.

Look, can we not arrange for some sort of moratorium on this to-and-fro guesswork until such a time as we actually have some substantial scene-of-the-crime evidence to go on, as opposed to very clever people making educated guesses based on photographs taken from orbit?

NASA manager opposed to Bush’s lunar plans

The moonSome dissent in the ranks at NASA; the man who led the development of the Apollo lunar module has come out in vocal opposition to plans to use explorations of the Moon as a test-bed for eventual manned missions to Mars; instead, he argues for full exploitation of the ISS and further robotic missions to the Red Planet.

Arguments of this type are ten a penny in space politics, which is a landscape of conflicting ideologies; Moon versus Mars, robotic missions versus human missions, and so on. An essay at The Space Review argues that these conflicts are “zero-sum games”, and a waste of energy and resources that could be better expended by the different groups working together toward common goals. Human nature being fundamentally factional, I’m not going to hold my breath just yet. [Image by jurvetson]

Greening the Red Planet – scientists test plausibility of Martian trees

treesIf we were to colonise Mars, we’d need to give it an atmosphere. The best way to do that would be to duplicate the creation of atmosphere here on Earth – by letting plant life do the work for us. With this in mind, scientists are investigating
the trees that grow on a lofty extinct volcano in Mexico, to see if their ability to survive in the thin atmosphere could be transferred to the Martian surface

The hazards for life on Mars

It’s a tautology to say that Mars isn’t the most friendly environment for human explorers. In addition to the lack of atmosphere, fluctuating temperatures and high levels of cosmic radiation, fierce storms of super-fine Martian dust could present a serious problem for bold pioneers on the Red Planet’s surface. In fact, Mars’ surface is inimical to local lifeforms, too – which is why NASA’s forthcoming Phoenix Lander will be digging beneath the surface in its hunt for indigenous microbial critters.
