Viking 2

  1975-083A

---

The Viking A spacecraft was launched on 1975 Sep 9 at 1839 by Titan IIIE Centaur from Cape Canaveral and became Viking 2.

The initial injection had a closest approach at 1976 Aug 9 0919 UTC with a miss distance of 655575 km (BT,BR= 581970, -301786).

Once in solar orbit, the MC1 burn was made on Sep 19 to correct the trajectory. An approach burn was made on 1976 Jul 27.

Mars Orbit Insertion was on 1976 Aug 7. A series of orbit trim burns were made to synchronize the orbit, ending with MOT4 on Aug 27. The Lander was separated on Sep 3. In this case, the bioshield base remained attached to the Orbiter, VO-2.

After a propulsion test on Sep 29, a major orbit change was made on Sep 30, with the inclination increased to 75 deg. The Viking Extended Mission began on 1976 Dec 14. On 1977 Mar 2, VO-2 had re-synchronized its orbit over the VL-2 landing site. On 1977 Apr 18, the Survival Automatic Mission was begun while Mars approached perihelion (Apr 30).

On 1977 Sep 26, VO-2 trimmed its orbit to approach Deimos. Another burn on Oct 9 synchronized the orbit with that of Deimos. Deimos encounters followed on Oct 10, Oct 12, Oct 15, and twice more in the Oct 16-22 period. The Oct 15 encounter was only 33km from the center of Deimos. A burn on Oct 23 ended the Deimos encounter period.

The Bioshield base was finally jettisoned on 1978 Mar 3. After Mars aphelion on Apr 9, the Viking Contination Mission began on May 31. However, VO-2's attitude gas was exhausted at 0601 on 1978 Jul 24 and the mission came to a close.

Viking Lander 2 (VL-2) landed on Mars on 1976 Sep. The biology unit operated until 1977 May 28 and the data storage memory failed on 1979 Nov 19. Low battery voltage on 1980 Apr 12 caused the end of VL-2's mission.
