  1974, at an altitude of about 47,000 km. A final Mercury encounter at an 
  altitude of 327 km. Tests were continued until March 24, 1975, when mission

  of communication blackout, and the Orbiter did not check in 20 minutes 
  later at the end of the blackout period. Cause unknown; trajectory of MCO
  unknown, although it it thought that it did not crash into the Martian

  gotten off-course, for unknown reasons.
