The Phoenix mission, which discovered indisputable proof of water on Mars, went quiet and the mission has been ended by NASA. It was facing declining power output in the Martian winter when a dust storm apparently covered up enough of the solar cells' capacity to send it below the likely threshold for recovery. Like nearly all Mars missions that actually made it to the surface, it outlasted its expected lifetime by a considerable amount. It operated for 5 months, two months longer than designed.
