Appropriations Bill Threatens Future Space Science Missions

ColdWetDog writes "A brief story in the Atlantic notes that the U.S. Senate's energy appropriations bill has failed to supply funds to continue Plutonium-238 production, needed for radioisotope generators for NASA's interplanetary probe programs. No PU-238 means no more missions like Cassini-Huygens, or ones that go places where solar cells won't produce enough power. The article notes that the only other source of PU-238 is Russia — either through the government or through trolling through Siberia and the Russian coastline looking for old Soviet Era lighthouses and power stations."

Democrats refuse to cut government staff or social programs, anything that might secure votes, so they go after unpopular programs. The thing is that Democrats, like Republicans only care about the jobs of people who will keep them in power.

      NASA happens to be one of those unpopular programs. You have the conservatives who think the money should go to defense to protect us from terrorists..

It's not limited to space tech - it's very debatable as to whether it would be even possible to re-import a lot of the tech jobs (such as plasma TVs, digital cameras, etc) back into the US due to the total lack of the necessary skills and experience. It's no good people whining about the problems caused by globalization if they then force both the local talent and the local jobs overseas. In the case of NASA, this would be to Europe and Russia, though to some extent India as well. The scientists want the same stuff done and if the former Soviet Union is going to be more obliging than Congress, then that money (and those scientists) won't wait on Congress. They'll go where the action is, same as everyone else.

      Of course, this would not be such a catastrophe if America developed new industries and new skills to fill in the gaps every time work got exported. You can't do everything single-handed and it makes sense to export some things. Likewise, overseas markets take time to ramp up and have only finite workers with the necessary abilities. So long as you keep moving forwards, you don't lose anything by donating what is no longer practical. The catch is, you've got to move forwards for this to work.

      Re-inventing the Saturn wouldn't have helped much, since the Russians could adapt Soyuz to do the same work for less. Projects like the Blended-Wing Body passenger jet NASA was working on, the turbine-assisted ramjet, or the now-abandoned hypersonic jet - these are the things that could have kept NASA ahead of the curve. In F1, the saying is that if you're not moving forwards, you're moving backwards. The current state of funding for NASA, combined with the brain-drain and transfer of funds to places more willing to venture into space, is a perfect demonstration of how this applies to every industry.
