Aerogel For Mars
Are you at the point where you don't care if we colonize another planet or not? We know that only the rich people will be able to afford to go anyway (perhaps along with people they select as their slaves), and that doesn't sound like a world I even want to be part of. We're already in a world where the 1% runs everything, so why spread that across the universe? As exciting as space exploration is, part of me just doesn't want it to work for humans. We've had our run; let the octopus have a go of running things!
