The mission was launched successfully on August 8, 1989, lasted just over 5 days, and traveled 2.1 million miles over 81 Earth orbits. The altitude of the mission is classified, however the altitude must have been between 220 kilometers (140 mi) and 380 kilometers (240 mi), based on the distance traveled and number of orbits.
