The Curiosity Mars Rover experienced a memory issue which as resulted in a halt to normal operations. Controllers are executing a planned fail over to the back computer (Side B). Part of this process is a transition to a “safe mode” during which time there are minimal activities executed by the vehicle. The rover’s “B-side” computer assumed control via commands from the mission operations team on Feb. 28 when the “A-side” computer that the rover had been using demonstrated symptoms of a corrupted memory location. “We are making good progress in the recovery,” said Mars Science Laboratory Project Manager Richard Cook, of NASA’s Jet Propulsion Laboratory. “One path of progress is evaluating the A-side with intent to recover it as a backup. Also, we need to go through a series of steps with the B-side, such as informing the computer about the state of the rover — the position of the arm, the position of the mast, that kind of information.”
The root cause of the issue is not yet know and is still being investigated.

Even after discovery of oxygen. how can form life on mars .Is climatic condition favorable?
The low air pressure on Mars (it is really almost a vacuum) makes the possibility of life at the surface low. Remembering that no all life needs oxygen where would it exist then? Most likely underground. If you assume that at some point in the past Mars had Water and life then it is also logical to assume it existed beneath the surface, just as it does here on Earth. Radiation and other consideration make the conditions on the surface of Mars less likely but it may be perfectly reasonable to think that the conditions under the surface are more similar to Earth today and there may actually be life there.
