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."
Many short-lived isotopes are in short supply. There's very limited US tritium production, medical radioisotopes production is so limited that there are medical shortages, and there are fewer research reactors operating. Transmutation is almost a dying technology.
Most of the radioisotopes were made in facilities built for bomb programs. Both the US and the USSR now have far too much bomb-grade PU-239, which has a half-life of 24,000 years. The giant nuclear facilities of the Cold War are mostly idle, or are hazardous waste sites.
The smaller nuclear powers are mostly separating uranium isotopes, which today is a centrifuge operation carried out in plants of modest size. The old gaseous diffusion plants were huge - square miles of plant.
1) I heard recently that the reason unemployment remaining flat because the government as a whole is cutting jobs (mostly contractors) at the same rate the private sector is creating jobs. That sounds pretty significant to me, maybe you wouldn't call it "devastating" but it's definitely relevant to the discussion.
2) Science and technology investment, of which NASA is a part, is precisely that: an investment. Infrastructure, education, health care, and environmental regulations are also investments that increase productivity over the long term. Cut them, and you reduce economic output (and tax revenue) in decades to come.
3) Things that could be cut with fewer long-term consequences: tax breaks, subsidies, and foreign wars. Also social security reform with means testing, and a health care system that does not involve siphoning billions of dollars into the pockets of insurance executives.
BTW, I don't know why people (including Obama) think cutting business taxes will spur hiring. No business is going to hire unless they see demand for their services, and demand is spurred by consumer wealth, not business wealth. Unless the people who are actually employed get paid more, they will not increase demand and businesses won't hire, no matter how "cheap" employees become.
