Factual corrections to points made by Paul Spudis: eight week round-trip missions to NEAs have been proposed (see earlier posts on this blog); most asteroids rotate at very, very low speeds; most do not have “co-orbiting clouds of debris;” resources will be collected at asteroids and processed in artificial ‘gravitational’ environments at LEO. These are exciting, solvable engineering challenges. Solvable.
“From a technical point of view, we’re much closer today to sending humans to Mars than we were to sending men to the Moon in 1961. […] While there are resources on the moon there are vastly more on Mars. There’re continent sized regions on Mars that are 60% water in the soil. There’s complex geological history which has created mineral ore. There’s carbon, which is necessary for life and for plastics. There’s nitrogen. There’s a twenty four hour day. […] The reason why it is important to do something as hard as exploring and ultimately settling Mars, is because of what it would do for opening up and creating the prospect of a human future with an open frontier rather than a limited frontier of a world of limited resources, in which choices are becoming ever closer and smaller and freedom is ever more limited.“
If Lunar advocates were at a bar they’d drink alone. Soda. After having attended several space-related conferences each year for over a decade, one characteristic of moon-first advocates which has been unfailingly predictable: they are boring as hell.
