NASA Ponders Postponing Launch until July

BitFluid writes "According to Sun-Sentinel.com, NASA is considering postponing its Return to Flight shuttle launch because of 'ongoing concern about possible ice buildup on a liquid oxygen propellant line.' Apparently, that stuff turns into debris on launch, a risk they need time to investigate. If delayed, the target launch window becomes July 13 through July 31."

      The Shuttle is the only vehicle capable of completing the International Space Station. If you stop flying the shuttle right now, the Space Station would be doomed. That's billions of dollars worth of hardware wasted.

      If you are referring to the CEV its not a few years, its more like a decade. The only thing happening in a few years, maybe, is a test flight by the two teams of an unmanned tin can maybe in 2008 but it would be a miracle if they held that schedule, this is NASA, Boeing and Lockheed after all. The earliest there would be a manned flight is 2014 and that is pretty much a fantasy target.

      Here is a biting editorial on the giant mound of contractor pork and red tape that is CEV. Transformational Space, the one fresh and innovative company in the early running, apparently pretty much abandoned bidding on it when they saw it was business as usual for NASA and structured so only Boeing and Lockheed could or would compete for it.

      Even if a manned CEV ever flies which is a long shot given NASA's record with new manned vehicles since the shuttle, you are probably talking about a relatively tiny conical capsule, yes after a decade of new development and billions of dollars you are going to pretty much be back where we were in the 1960's, a tiny vehicle capable of carrying a few people and a tiny amount of cargo. The launch vehicle will be a derivative of existing expendable launchers and wont have anything close to the power of a Saturn V so every mission profile beyond putting a tin can in LEO requires multiple launches and docking all the pieces in orbit.

      Bottomline is what is in NASA's pipe is less than what they had in the 1960's but at a staggering cost in time and money.
