ORIGINAL: ARIES83 I was really not impressed that they don't have a successor spaceplane... The new vehicle isn't just a step backward IMO It's a leap... The Shuttle was definitely innovative, complex, and ambitious – but it could be argued it went too far in those directions. As SWDesertDom pointed out, there were significant problems inherent to the design. The enthusiasm with which Endeavor was bid farewell is, I think, fairly illustrative of some sort of success as a source of inspiration; however, there is a pragmatic case to me made that a program with a 1.48% catastrophic failure rate, fourteen lives lost, a lack of capabilities beyond LEO, and significantly reduced payload versus the Saturn V actually marked a step back from the previous program. The Shuttle never lived up to the reliability or launch frequencies that were its supposed advantages and, at $450 million a launch, it didn't end up being cheaper than expendable launch vehicles, either. A return to capsules might superficially seem like a step back, but conservative design isn't necessarily always a bad thing for progress. quote:
