Science: With too many missions and not enough money, NASA’s $5.5 billion science program is in a terrible fix. A 5-year plan that would cancel projects nearing completion, decimate disciplines, and slash funds to analyze data so upset space science researchers when NASA released it in February that officials gave the community an unprecedented shot at coming up with something better. But the scientists who met here last week as members of a newly expanded NASA advisory committee couldn’t agree on an alternative approach that wouldn’t bust NASA’s proposed budget for 2007. That failure could leave the fate of the program to the whims of Congress.
