Hoping to "develop a sustainable model for persistent, long-term" private sector funded human space exploration, the Defense Advance Research Projects Agency has put out an open call for ideas on how to design a spaceship capable of colonizing another planet, with concerns ranging from intergalactic food manufacturing to creating artificial gravity, currently only possible by hiring an astronaut who constantly will pretend he has a debilitating terminal illness. Judging from current posts, the future of space travel will include:
Walls that act like e-paper..."If...the walls have changeable pictures of nature, it would make a great difference in mental health of the crew". Coincidentally, it would also make for terrible spaceship walls.
Convenience..."[A] working space elevator", as even at zero gravity walking up stairs is still a huge pain in the ass.
Tons of chicks!..."The crew should be one man and lots of women...since 1 man can still impregnate lots of women...whereas 1 woman can only have one baby, unless she octomoms". Apparently twins are not possible in space.
Cable TV..."The Babylon 5 design seems quite useful", which likely comes from someone who's only deep space experience ends with a Nine.
Skynet..."We will probably be replaced by intelligent machines by the time any 'life form (carbon or silicon based) will get off this rock and make it to another star system."
Since DARPA is so foolish they think the public is going to help design a space ship, send your ideas to us instead, and we'll publish the one most likely to send us hurtling through the galaxy of humor.
