It takes a year to make, and is the starting point for all coming debate by Congress. It's the President's Budget Request, and understanding how it comes together is an important part of being an effective space advocate.
The first results of the Rosetta mission are out in Science magazine. The publication of these papers means that the OSIRIS camera team has finally released a large quantity of closeup images of comet Churyumov-Gerasimenko, taken in August and September of last year.

The rover is now preparing for a drilling campaign.
