Two of the four reaction wheels failed, and Kepler scientists say the spacecraft needs at least three reaction wheels to be able to point precisely enough to continue the mission. In the latest update from Kepler, mission manager Roger Hunter says that the team has made a little headway and had initial success in testing the two failed reaction wheels. But the big test will come later to see how much friction the two wheels generate with continued use.
