[quote name='Drocket']There's 3 key problems with NASA right now:
1) The shuttle design is/was a bad decision. This is something that most experts in the field figured out shortly after they were originally built, but at that point, NASA couldn't/wouldn't change its mind because it had spent billions designing and building them.
2) NASA desperately needs to replace the aging and not particularly well designed space shuttles, but simply doesn't have the budget to do so. If NASA was given a mandate (much like 'go to the moon by the end of the decade' like they had in the 60's) and the budget to fulfill it, they would do a whole lot of sweet things. Instead, they barely have the cash to keep patching up shuttles that are 25 years old. The shuttles are actually older than their originally designed lifespan, even if their design had been perfect.
3) The US is focused way too much on safety anymore. When the moonlanding too place, there was a HUGE chance that it would end badly - and they went anyway. Anymore, if there's even a minor possibility of a problem, the launch gets scrubbed.
In summation, NASA needs a whole lot of money and a pair of balls. Then we'd see some pretty sweet things.[/QUOTE]
It costs NASA in the ballpark of $300-400 million dollars per flight, and months, if not years, to prep for the next flight. That is just too much money and too much time for NASA to be spending on these shuttles. I'm hoping to see where the SpaceShipOne will be headed as it's very impressive for costing about the same as a yacht. Bush has ordered another trip to the moon by 2020, so there's reason for them to either scrap the discovery or revamp it and fix its problems.
They also are keeping their eye on their rovers on Mars and making sure they don't get caught up for 5 weeks on sand dunes like Opportunity just did back at the end of April. They've done their job, though, finding lots of evidence of liquid water having been around on Mars many, many years ago.
