Apstar

Communications satellite series for APT.

Country: China. Spacecraft: HS 376, FS-1300, HS 601. Launch Vehicles: Chang Zheng 3, Chang Zheng 2E, Chang Zheng 3B, Zenit-3SL. Launch Sites: Xichang, Kiritimati. Agency: PRC, APT Satellite Company, Palo Alto.

1994 July 21 - . 10:55 GMT - . Launch Site: Xichang. Launch Complex: Xichang LC1. LV Family: CZ. Launch Vehicle: Chang Zheng 3.

Apstar 1 - . Mass: 1,383 kg (3,048 lb). Nation: China. Agency: APT Satellite Company. Program: Apstar. Class: Communications. Type: Civilian communications satellite. Spacecraft: HS 376. USAF Sat Cat: 23185 . COSPAR: 1994-043A. Apogee: 35,789 km (22,238 mi). Perigee: 35,785 km (22,235 mi). Inclination: 0.00 deg. Period: 1,436.12 min. Asia-Pacific communications. Operated in geosynchronous orbit at 138 deg E in 1994-1999. As of 5 September 2001 located at 138.04 deg E drifting at 0.004 deg W per day. As of 2007 Mar 11 located at 141.96E drifting at 0.002W degrees per day..

1995 January 25 - . 22:40 GMT - . Launch Site: Xichang. Launch Complex: Xichang LC2. LV Family: CZ. Launch Vehicle: Chang Zheng 2E. FAILURE: Shortcomings in the guidance system lead to the vehicle not anticipating the true effects of horizontal wind-shear once the mountains surrounding the launch site were cleared. This caused the nose fairing to collapse and the spacecraft to be destroyed.. Failed Stage: G.

Apstar 2 - . Mass: 2,830 kg (6,230 lb). Nation: China. Agency: PRC. Program: Apstar. Class: Communications. Type: Civilian communications satellite. Spacecraft: HS 601. Decay Date: 1995-01-25 .
Because the Apstar failure happened a few seconds later than Optus, the consequences were catastrophic. The vehicle was destroyed, and the falling wreckage landed on a village down-range of the launch site, killing at least 20 and perhaps as many as 120 people.

1996 July 3 - . 10:47 GMT - . Launch Site: Xichang. Launch Complex: Xichang LC1. LV Family: CZ. Launch Vehicle: Chang Zheng 3.

Apstar 1A - . Mass: 2,800 kg (6,100 lb). Nation: China. Agency: APT Satellite Company. Program: Apstar. Class: Communications. Type: Civilian communications satellite. Spacecraft: HS 376. USAF Sat Cat: 23943 . COSPAR: 1996-039A. Apogee: 35,791 km (22,239 mi). Perigee: 35,785 km (22,235 mi). Inclination: 0.00 deg.
