The crew of the mission was sent by MirCorp, a privately funded company, to reactivate and repair the station.  The crew also resupplied the station and boosted the station to an orbit with a low point (perigee) of 360 and a high point (apogee) of 378 kilometers (223 and 235 miles, respectively).

The mission was the first privately funded mission to a space station.
