Shenzhou 2 (Chinese: 神舟二号) launched on 9 January 2001, was the second unmanned launch of the Shenzhou spacecraft. Inside the reentry capsule were a monkey, a dog and a rabbit in a test of the spaceship's life support 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 12 January it once again changed its orbit to 329.3 by 339.4 km. A third orbit change came on 15 January, 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 microgravity crystallography experiment; animal species including six mice, and small aquatic and terrestrial organisms; cosmic ray and particle detectors and a gamma ray burst detectors. To test the radio transmitting systems taped messages were broadcast from the spacecraft.
