FLORIDA: The Mars rover Spirit is stuck in soft soil while driving along a low plateau.
NASA said on Tuesday that engineers have temporarily stopped sending driving commands to Spirit while they diagnose the problem.
The six-wheeled Spirit has five working wheels. Its right-front wheel stopped functioning three years ago. The remaining five wheels sunk halfway into the Martian ground during a recent series of backward drives.
Spirit and its twin Opportunity landed on Mars in 2004. Last month, Spirit suffered bouts of amnesia, but has since recovered.
