Mission Status ReportNASA s Dawn spacecraft is preparing to observe Ceres on April 29 from an opposition position, directly between the dwarf planet s mysterious Occator Crater and the sun. This unique geometry may yield new insights about the bright material in the center of the crater. While preparing for this observation, one of Dawn s two remaining reaction wheels stopped functioning on April 23. By electrically changing the speed at which these gyroscope-like devices spin, Dawn controls its orientation in the zero-gravity, frictionless conditions of space. The team discovered the situation during a scheduled communications session on April 24, diagnosed the problem, and returned the spacecraft to its standard flight configuration, still with hydrazine control, on April 25. The failure occurred after Dawn completed its five-hour segment of ion

The men and women were followed for four years. The peo
