Submission + - NASA concedes defeat in effort to free rover
An anonymous reader writes: The US space agency NASA has conceded defeat in its battle to free the Spirit rover from its Martian sand trap. The vehicle became stuck in soft soil back in May last year and all the efforts to extricate it have failed. NASA says Spirit, which landed on the Red Planet ver six years ago, "no longer be a fully mobile robot," and has instead designated the once-roving scientific explorer a stationary science platform.
