I say, if there were ever an X3, we should go to Mars!!! (moon is closer, but, we don't want to be following in the footsteps of NASA forever...)
Could a team of X-Prizers beat the USA, Russia, China, etc. , to be the first humans on mars??

After you get out of Earth's atmosphere, you can pretty much coast along for a good portion of the way there... I don't know anything about Martian atmosphere, but its probably thicker than here, so you'd probably have to slow down a bit to avoid the extra friction....

As for the long trip there... you could probably time the launch date so that the trip is actually much shorter.

The real trick would be getting home! You'd need to store fuel for THAT LONG, and still have it work A-OK in seconds. And, both Martian gravity and excess atmosphere would be working against you... more fuel needed!

So what we're looking at, is we'd need a rocket capable of launching itself in one stage from mars, that we take up out of earth's orbit using boosters.
So from a current day NASA-tech point of view, we would have the crew riding in one of those giant liquid fuel tanks with 2 SRBs, strapped to another liquid fuel tank, with 2 SRBs.

Imagine THAT blowing up on the pad!
Still... it would be awesome. :P

Come to think of it, you'd definitely run out of gas too, if you were using cold jet manuvering thrusters.......
or would you just gimball the engine and do a short burn to make slight long term adjustments?
Or maybe a vernier system....

Dreaming of an X-3 competition... Although we're still extremely excited to see who will claim the glory of the X-1 Cup
An X-3 Prize would be of more significance than you probably realise. This would mean that a private space venture was able to outdo a goverment venture.

Great idea brain trust. Now who is going to raise the 100 billion dollars that it would take to make a mars prize feasible to investors?

Who says money should be the problem ? who says it has to make profits ? if it's just to be for the technology.. no problem, mars isn't that far.
A symbolic US$ 5 million is even good anough.

Now you'll start saying, too difficult....
Well, who says it's in 10 years.. this prize can be also won in 25 years, so all problems fixed.

But you're right that it won't be for a commercial succes within 5 a 10 years or so.

after x-prize, i don't think funding will be nearly as much of an issue. i say a $20 mil orbital x2 prize, $50 mil moon x3 prize. mars, $100 mil MAYBE for x4, asteroid mining or commercial space station might be better though.
