Mars 3 Orbiter
Mission Profile
Mars 3 was launched towards Mars from a Tyazheliy
Sputnik (71-049C) Earth orbiting platform. A mid-course correction was made on 8 June. The
descent module (71-049F) was released at 09:14 UT on 2 December 1971 about 4.5 hours
before reaching Mars. Through aerodynamic braking, parachutes, and retro-rockets, the
lander achieved a soft landing at 45 S, 158 W and began operations. However, after 20 sec
the instruments stopped working for unknown reasons. Meanwhile, the orbiter engine
performed a burn to put the spacecraft into a long 11-day period orbit about Mars with an
inclination thought to be similar to that of Mars 2 (48.9 degrees). Data was sent back for
many months. It was announced that Mars 2 and 3 had completed their missions by 22 August
1972.
