10:37 GMT - . Launch Site: Plesetsk. Launch Complex: Plesetsk LC132/1. LV Family: R-14. Launch Vehicle: Kosmos 11K65M.

Tsinghua - . Mass: 50 kg (110 lb). Nation: China. Agency: Tsinghua. Manufacturer: Surrey. Class: Technology. Type: Navigation technology satellite. Spacecraft: SSTL-70. USAF Sat Cat: 26385 . COSPAR: 2000-033B. Apogee: 713 km (443 mi). Perigee: 687 km (427 mi). Inclination: 98.14 deg. Period: 98.68 min.
Tsinghua University of Beijing satellite equipped with an imager, communications payload, and momentum wheels for 3-axis stabilisation. The 50 kg, 0.69 x 0.36 x 0.36m box-shaped satellite used a standard Surrey SSTL microsat bus.Tsinghua-1 was the first demonstrator for the planned Disaster Monitoring Constellation and carried a multi-spectral Earth imaging camera providing 39-metre nadir ground resolution in 3 spectral bands. The satellite also carried out research in low Earth orbit using digital store-and-forward communications, a digital signal processing (DSP) experiment, a Surrey-built GPS space receiver and a new 3-axis microsat attitude control experiment. Tsinghua-1 used the SGR-10, with 12 channels and equipped with two receive antennas, to investigate the use of GPS signals in microsat on-board attitude and orbit determination. In October 2000 Surrey Satellite Technology Ltd (SSTL) released a picture of Tsinghua-1 taken in orbit by the SNAP-1 6.5 kg nanosatellite.

10:30 GMT - . Launch Site: Taiyuan. LV Family: DF-31. Launch Vehicle: KT-1. FAILURE: Second stage failure.. Failed Stage: 2.

HTSTL-1 - . Mass: 50 kg (110 lb). Nation: China. Manufacturer: Tsinghua. Class: Technology. Type: Navigation technology satellite. Spacecraft: HTSTL. First attempted launch of the all-solid-propellant KT-1 launch vehicle. The 50 kg test satellite, built by university students, was to have been placed in a 300 km polar orbit..

15:59 GMT - . Launch Site: Xichang. Launch Complex: Xichang LC1. Launch Pad: LC1?. LV Family: CZ. Launch Vehicle: Chang Zheng 2C.
