HT is by no means dead; you can spend a lot of extra time putting a screw through a board with a hammer but a screwdriver is probably the better and more efficient choice for the job.

It's not about the will to do it (although that does play a role). The minute the copycyt Chinese land on the Moon the US -- possibly together with Russia &/or the EU -- will put an Apollo-type effort into getting to Mars. Hell, Just read Mary Roach's Packing for Mars (ISBN 978-1-85168-780-0) and see what nearly insurmountable problems there were in getting to the Moon, and she really only deals with life sciences, not physics.
The problem is that we can't realistically get a payload of sufficient size there. The technological hurdles are easy; the problems are physics and biology. We can build a dozen rockets, take advantage of orbital mechanics for unmanned segments, launch 'em off three full-size gantries together so that one launch window serves three machines.
But before we even think about getting the people there we still have to figure out how to arrive, orbit, and then land precisely -- repeatedly -- unmanned, all while dealing with the 8-minute radio delay in the best of circumstances.
The problem of human physiology is even worse than the physics problem. We can come up with odd trajectories and multiple burns and en-route dockings to provide additional fuel to carry such things out. Have you ever seen the astronauts coming back from 3-6 months on the ISS? It takes a huge fucking crew to get them out of the return vehicle and into recovery. It takes three strong men just to pull those poor bastards off the couch and out of the capsule. And that's from LEO. There ain't no recovery crews waiting on Mars.

To even consider going to Mars we first need to send at least 5 rockets full of supplies and land them literally next to each other. We also need to park another 2 or 3 in orbit to hold fuel for Mars Orbit Docking in order to dock and go home within a reasonable time frame. Aldrin's free transfer trajectory is great but unsuitable for human passage.
Get the supplies and contingency machines in place, then think about it. But first figure out how to drop 5 tonnes safely to a very particular spot on the surface. Now do it repeatedly. Because that's what landing on Mars requires.

NASA is a palindrome: an agency formed that first couldn't get off the ground, then got up in the air, then into low orbit, then high orbit, then to the Moon, then to low orbit, and now can't even get off the ground. I used to be so proud of them...

When an OS -- even from a company you don't like -- does the job it's supposed to do, what's the problem? Of course I like my various *nix installs as long as they do what I need them to do, but if you have to use Windows for anything, XP is the last in a (supported) line which will still more or less do what you tell it to do. You may recall that XP (like everything before it) installs with a basic version of Win3.1.
