When I saw the Presidential Budget Request this year for NASA, I was heartened: lots of money for commercial space transport and science. Obama hasn't been a vocal supporter of NASA, so it was a relief. Congress has countered, however. The House just released its Appropriations bill that covers science funding for NSF, NASA, NOAA, and NIST. Almost across the board: cuts. Massive ones. This bill (PDF) actually keeps NSF at the fiscal year '11 funding, although that's $900 million less than the Presidential request. NOAA is being cut $100 million (2.2%), or $1 billion less than requested. NIST: cut by $50 million over FY11 (6.5%), $300 million less than requested. But NASA is the one where the cuts are nothing short of savage. The cuts total $1.64 billion from last year, which is nearly $2 billion less than requested. That's a cut of 8.8%. A billion of that is due to the Shuttle retiring, but the galling part is that the House is requiring that all funding for the James Webb Space Telescope, Hubble's successor, be cut entirely. In other words, they are canceling the JWST program. To be fair, the JWST project has been over budget, behind schedule, and mismanaged for years. It's sapped money away from other projects as well. But the reason this is so aggravating is that despite all that the pieces are built and currently being assembled. I'm not sure it's cost-effective to cancel it at this point; better to put a hold on it, audit the whole thing top to bottom, and re-organize as needed. JWST has been a real problem, but it will also be one of the most spectacular observatories ever built. A six meter mirror in space tuned for infra-red observations, it will see farther and in more detail than any space telescope ever built. It will see galaxies when they were first forming, it will image planets orbiting distant suns, and will map our Universe like never before. At this point, canceling it means billions of dollars will be thrown away, when the cost to complete it is far less*. Since this is a House budget bill, I called my Representative, Jared Polis, and left him a message. I also tweeted him:
