systems. The reentry module separated from the rest of the spacecraft after just over seven days in orbit, with the orbital module staying in orbit for another 220 days. Shenzhou 2 tested the spacecraft much more rigorously than its predecessor Shenzhou 1. After being launched into a 196.5 by 333.8 km orbit, 20.5 hours after launch it circularised its orbit to 327.7 by 332.7 km. Around 1220 UTC on January 12 it once again changed its orbit to 329.3 by 339.4 km. A third orbit change came on January 15 328.7 by 345.4 km. As well as the animal cargo, there were 64 different scientific payloads. 15 were carried in the reentry module, 12 in the orbital module and 37 on the forward external pallet. These included a

Successful reentry and failed landing

The signal for retrofire was sent at about 1015 UTC on January 16 as the spacecraft passed over the South Atlantic Ocean off the coast of South Africa. It landed in Inner Mongolia at 11:22 UTC. No photos were released of the landing capsule leading to some speculation that the reentry was not completely successful, though Chinese officials kept silent, only responded anomaly. The
