Today the New Horizons team released a new animation of images taken on approach to Pluto. The animation clearly shows how Pluto wobbles around the Pluto-Charon barycenter. It also shows something more exciting to the scientists: variations in brightness across the surface of Pluto. They also began releasing raw images to the Internet.

In the two months since I last checked up on the Rosetta mission, the comet has heated up, displaying more and more jet activity. Rosetta completed very close flybys on February 14 and March 28, taking amazing photos. But comet dust is making navigation difficult, so the mission is now keeping a respectful distance from the comet and replanning its future path.
