Apollo 17 launched from the moon to return to earth 51 years, 7 months and 6 days ago, and no one's been back since. I'm 50, and no one's been to the moon — or even outside low earth orbit — in my lifetime. The (manned) space age finished before I was born!
The idea that we should now attempt to colonise a planet or moon within the time it takes us to trash the earth into unlivability is fanciful, to say the least.
