What's interesting is that despite the consevatism, the space shuttle program, I think, has the worst mission success record. They've had what--14 deaths in the past 20 years?
From what I learned on my recent trip to Kennedy Space Center, the Space shuttle program is actually incredibly risky compared to other and past rocket designs. It's got solid rocket boosters that once lit, cannot be turned off. It's got no abort sequence until those SRBs are finished firing. Hell, the rocket itself is asymmetrical and rocks back and forth before liftoff.
Contrast all this with the Soyuz and our very own Saturn V designs. Saturn V I believe had 100% mission success during all our trips to the moon. It's liquid engines could be shutoff almost instantaneously during an abort sequence AND it had a blasting cap on top that would fire if the crew needed to abort during launch. Oh and the rocket did all this while being something like 95% efficient.
The space shuttle does have the ability to snatch satellites out of space and bring them back to Earth. No other craft does this, and this was probably an important feature during the Cold War. NASA doesn't talk much about the military uses of its spacecraft.

Why NASA abandoned this program is beyond me.
