On July 18, 2013, the House Science, Space, and Technology Committee held a markup of the NASA Authorization Act of 2013 (H.R. 2687). The bill, which reauthorizes programs at NASA for two years with a top line budget of $16.9 billion, was approved by a vote of 22 to 17 along party lines.
The bill authorizes a total of $4.6 billion for science, including $1.5 billion for planetary science and $1.2 billion for earth science. This represents a reduction of the earth science budget by about one-third, to 2008 levels.
