Inspector was a spacecraft intended to serve as a remote inspection device for the Mir space station. Built by Daimler-Benz Aerospace, it was delivered to Mir by a Progress-M supply vessel and deployed on December 17, 1997. However, Inspector failed, possibly due to a faulty gyro, and was abandoned by the cosmonauts. Mir was boosted out of the way, and the inspection craft became an unintended microsatellite before its orbit decayed on November 2, 1998.
