ASC-1

 1985-076C


American Satellite Corp. was a joint venture of Fairchild and Continental Telecom, Inc. It was bought by Contel in 1985, forming Contel ASC. Contel merged with GTE in Mar 1991, and Contel ASC became part of GTE Spacenet.

The ASC 1 (sometimes referred to as Amersat 1 in the early 1980s) satellite was launched in 1985 on Shuttle mission 51-I. It was used for data transmissions and occasional business video.

STS-62 (Columbia)

 1994-015A


STS-62 was launched on 1994 Mar 4 on a research flight. The USMP microgravity payload was the main science. 55 melting and solidification cycles were carried out for the MEPHISTO experiment to study phase transitions. The IDGE experiment showed that dendritic solidification of molten metals happened at a different rate when supercooling effects are low. The Zeno experiment located the critical point of xenon to an accuracy of 10 microKelvins.

The OAST-2 payload studied spacecraft glow and carried out technology tests.The DEED dexterous end effector demonstration was used on the end of the robot arm, using its MAT magnetic attachment tool to pick up objects and a mirror to reflect its target to a payload bay video camera. MAT and a task bar were stored on an ESAP (GABA) plate on the sidewall. The DEE was used successfully, and the MAT could grapple objects within a distance of 1 cm, although there were problems in daylight with aligning the tool.

Intelsat 708

 1996-F01


Intelsat 708 was flown to Xichang Space Center to become the first Intelsat for launch on a Chinese rocket. It was the very first flight of the Chang Zheng 3B variant, which combined the CZ-3A core with the CZ-2E strapons. As the CZ-3B cleared the launch tower on 1996 Feb 14, the rocket tilted over and started flying horizontally. One observer described it as a `20-story cruise missile'. It crashed into the ground 25 sec after liftoff, destroying buildings and killing six people with 57 injured, according to the Chinese. Western observers claimed much higher casualty figures. The accident investigation found that the inertial guidance system failed 2 seconds after takeoff.

The 2011 CZ user guide records the satellite mass as 4594 kg, although contemporary accounts said 3750 kg.

Salyut 1

  1971-032A


The first DOS station, DOS 1, was originally to be named Zarya, but was renamed Salyut after launch on 1971 Apr 19. It had the designation 17K No. 121.

The first crew reached the station on Apr 24; Soyuz-10 soft docked but could not complete the seal and had to undock and return to Earth without boarding the station.

A second crew docked on Jun 7 aboard Soyuz-11. Georgiy Dobrovolskiy, Viktor Patsaev, and Vladislav Volkov became the first space station crew, and settled into a routine of on-board experiments. After shattering the spaceflight duration record they prepared to return to Earth. The crew transferred back to Soyuz-11, closed the Salyut hatch, and undocked from the station completing the first station expedition. 

Salyut was maintained in orbit for several months, but was deorbited over the Pacific in October when it became clear that the Soyuz program would remain grounded for some time. This set the precedent for the controlled reentry of massive spacecraft in empty areas of the South Pacific Ocean.

Soyuz-10 was docked to Salyut for 5h30m. Soyuz-11 was docked for 22d10h40m and the hatch open/close time was about 22d08h35m.

Sakura 1

 1977-118A


NASDA's CS (Communications Satellite) program was aimed at developing a domestic comsat system for Japan. The telecom services were provided by NTT. CS 1 was built by Mitsubishi and Ford, and launched on an American Delta from Cape Canaveral in Dec 1977. It was named Sakura (`cherry blossom') after launch.
