NASA Prepares Discovery for Launch 129
eggoeater writes "Yahoo! reports that Kennedy Space Center is buzzing with excitement over the likely launch of Space Shuttle Discovery this Spring. It's been just over two years since the Columbia tragedy and the Discovery has been outfitted with many new safety features, including the removal of the foam from the external tank and pressure sensors on the wings that would detect an impact. Quote from launch director Michael D. Leinbach: 'It's all converging on what looks like May 15 to start flying the shuttle again.'"

So, if congress is the boss because it controls the purse strings, how do you think NASA will behave? Just like any employee, they quickly realize the boss's goal and agenda and make it their own. So, the people who manage NASA are not in the business of cost effective space exploration. In fact, quite the opposite. They're in the business of spending tax dollars in several congressional districts.
And that's why we need private space exploration and development, and we finally have it. Many companies now see the possibility and they have the vision and motivation to do what NASA couldn't.
It's sad that NASA did so much in the early years and then the political process ruined it late in the Apollo era. Despite some very bright scientists, engineers and astronauts, they just can't help being a government bureaucracy. Why?

Its an interesting hybrid of lifting body and capsule, it will reenter like a lifting body but pop a parachute and land with a thud like Soyuz. I think its fairly similar to canceled X vehicle Burt Rutan was developing as the ISS lifeboat.
It will carry 6 people or 700 Kilo's of cargo. If you hang one of these on the ISS as the emergency vehicle you could raise the manning level to six people and actually do some research on it for a change. The cargo capacity also appears well suited to resupply the ISS, it can carry a lot more than Progress and Soyuz.
They hope to have it flying by 2010 which just happens to be about when the Shuttle stops flying. They need $10 billion roubles to finish it which sounds like a lot but the exchange rate is 28 roubles to the dollar so that is only $350 million dollars. By contrast NASA is wasting $500 billion on CEV this year alone and they wont get ANYTHING for it other than pretty computer generated images. Building CEV is going to cost at least 36 times as much as Kliper and is scheduled to be 4 years later for its first manned launch, 2010 versus 2014.
Sure looks to me like Russia is hoping to fill the void the Shuttle is going to leave in 2010 with Kliper and essentially take over the ISS if they get the funding to develop it. Whatever happens the Russians are going to be the ONLY people putting people in to LEO on a regular basis from 2010 to 2014, maybe the Chinese will launch a few people too. NASA ought to be ashamed, very ashamed, again.
Seems to me like the Europeans or Japanese should jump at helping with the funding for Kliper. Their investment in ISS has been largely destroyed by NASA's failures, most of their modules are sitting on the ground and they may never get the astronauts onboard the ISS needed to do their planned research. For $350 million they could save their ISS investment and in partnership with Russia develop their own manned space program free of the boat anchor that is NASA, Boeing, Lockheed.
Seems to me like the Chinese could partner with Kliper as well with their new found wealth and jump start their rather slow manned space effort, especially if they get technology sharing in return for cash.
P.S.
I submitted the Kliper article when it came out a few days ago and it was rejected. It is real news versus this fluff piece.

I hate to break it to you, the only reason CEV is so vastly more expensive is because NASA, Boeing and Lockheed are in the loop and of course the wage rates are higher in the U.S. than the U.S.S.R., especially after Boeing and Lockheed slap on their overhead. I assure you NASA, Lockheed and Boeing are experts at wasting money, you need look no further than the Shuttle and the ISS to see that.
As best I understand it the CEV prototype launches in 2008 wont address ANYTHING involving manned flight, going to the moon or mars. Its going to be a tin can that isn't man rated launched on a more less existing booster, heavy lift versions of Atlas, Delta or Titan and will barely make it to LEO. Not sure the first launches in 2014 with men will do anything but LEO either. Somebody is going to have to build a major new heavy launcher to go back to the moon or do multiple launches (i.e. fuel and a space tug on one, and then the CEV on another).
Its very much open to doubt if the CEV in its first iterations will address going to the Moon or Mars at all in 2014 either though it remains to be seen what they propose. I think there is at least a chance they will have to develop landers on top of the CEV to go to the moon(and a better booster). I'm skeptical that they are going to land the whole CEV on the moon and blast if off from there. The Apollo strategy was the right one for a lot of reasons. To do the Moon right chances are a several vehicles will be required.
Its completely delusional to think CEV will be usable at all for going to Mars. The requirements for going to LEO and the Moon are VASTLY different from those for going to Mars. If you use the same vehicle for all three its going to be either complete overkill for LEO and the Moon or woefully inadequate for Mars. The Mars vehicle is going to have to a completely different vehicle and boosters, its going to have to be way bigger or the crew will both run out of supplies and go bonkers trapped for that long in a tiny capsule.
I wouldn't be surprised if they try to do a shuttle with CEV, and do one size fits all for all three missions, but it will be the same disaster the Shuttle was, heavy and expensive, jack of all trades, master of none.
