Fourth and final test flight of the Shenzhou spacecraft, without crew on board. The spacecraft was flown in the same configuration as a crew-carrying mission, and as such two dummy astronauts were carried on board, as are sleeping bags, food and medication. The control systems were fitted with ability for manual control and emergency landing. The windows were constructed of a new material that was designed to stay clear even after reentry to allow an astronaut to confirm that the parachutes have deployed properly. The spacecraft carried 100 peony seeds to investigate the effect of weightlessness on plants grown from them. The 52 experiments onboard investigated areas in physics, biology, medicine, earth observation, material science, and astronomy.
The Long March 2F is a Chinese orbital carrier rocket, part of the Long March 2 rocket family. Designed to launch the crewed Shenzhou spacecraft, the Long March 2F is a human-rated two-stage version of the Long March 2E rocket, which in turn was based on the Long March 2C launch vehicle. It is launched from complex SLS at the Jiuquan Satellite Launch Center.
The spacecraft was equipped for a manned flight, even featuring a sleeping bag, food, and medication. The windows were constructed of a new material that was designed to stay clear even after reentry to allow an astronaut to confirm that the parachutes have deployed properly. It was said that the spacecraft flown on Shenzhou 4 had no major differences to that used on Shenzhou 5. It flew with the ability for manual control and emergency landing, systems needed for a manned flight. A week before the launch, astronauts trained in the spacecraft to familiarise themselves with its systems.
Shenzhou DetailsThe China Aerospace Science and Technology Corporation (CASC) is the main contractor for the Chinese space program. It is state-owned and has a number of subordinate entities which design, develop and manufacture a range of spacecraft, launch vehicles, strategic and tactical missile systems, and ground equipment. It was officially established in July 1999 as part of a Chinese government reform drive, having previously been one part of the former China Aerospace Corporation. Various incarnations of the program date back to 1956.
