We now have the two ingredients. Reuters reports that it is very possible that life supporting soil and water have been found on Mars.
Now all we need are some instant martian pills. Or some fruit and vegetable plant seeds I guess...
This is a major discovery. One of the greatest obstacles delaying the colonization of Mars has been the lack of resources and the costliness of transporting it all. If a Human Martian colony (sad that I have to specify that) can at least partially support itself, will save thousands if not millions of taxpayer dollars.
Hurry up and colonize it before I get to old to travel!
Would you pay $500,000 for a one week vacation on Mars? Keep in mind that it will take much longer to get there and the one week is just your time on the planet.
