Progress M1-5 was the Progress spacecraft which was launched by Russia in 2001 to deorbit the fifteen-year-old Mir space station in a controlled fashion over a remote ocean area, far away from shipping lanes - otherwise Mir's orbit would have decayed uncontrolled over time (like e.g. Skylab), with debris potentially landing in a populated area. The Russian Aviation and Space Agency, Rosaviakosmos, was responsible for the mission.
