Space science at NASA has taken a hit. While President Bush鈥檚 budget request on Monday allocated the agency $16.8 billion for 2007, an increase of 3.2 per cent, funding for NASA science increased by less than expected, just 1.5 per cent. Projects now on ice include missions to find extrasolar planets and detect gravitational waves.
