Mars Reconnaissance Orbiter Mission Status
NASA's Mars Reconnaissance Orbiter put itself into safe mode -- a precautionary status with minimized activities -- on March 14. It remained healthy and in communication with Earth, but with no science observations, while the flight team examined engineering data. On March 20, the team brought the spacecraft back out of safe mode.
