Failed soil-return mission to Martian moon Phobos. The main propulsion system, which was to have boosted the probe out of earth parking orbit to trans-Mars insertion, failed to ignite. Attempts to communicate with the spacecraft partially succeeded but it could not be commanded to conduct an engine burn at a later opportunity. Destroyed on reentry into the earth's atmosphere.
