Palapa A1 and A2 were the initial elements of Indonesia's domestic communications satellite system. The spacecraft were identical to Canada's Anik and Western Union's Wasters except for a modified parabolic reflector, enlarged to give maximum illumination of the Indonesian land mass. Operational lives for Palapa A1 and A2 ended June 1985 and January 1988, respectively. Spacecraft: Based on Hughes HS-333 design.1.5 m diameter parabolic reflector with 12 transponders working through 125 Earth stations. Spin stabilised with despun antenna and feeds. Payload: Both satellites carried 12 transponders that provided 4000 voice circuits or 12 simultaneous TV channels to the country's 6000+ inhabited islands. References: 1 , 2 , 5 , 6 .

Viking 1 reached Mars orbit June 19, 1976. Landing was planned for the US Bicentennial on July 4, but was delayed until a suitable landing site was located. The lander separated from the orbiter and touched down on the western slope of Chryse Planitia (the Plains of Gold) at 22.3 deg N latitude, 48 deg longitude.

Lunar Sample Return. Landed on Moon 18 Aug 1976 at 02:00:00 GMT, Latitude 12.25 N, Longitude 62.20 E - Mare Crisium (Sea of Crisis). The last of the Luna series of spacecraft, Luna 24 was the third Soviet mission to retrieve lunar ground samples (the first two were returned by Luna 16 and 20). The mission successfully returned 170 grams of lunar samples to the Earth on 22 August 1976. References: 1 , 2 , 5 , 6 , 67 , 274 , 296 .
