Shenzhou 7

Shenzhou 7 was a China National Space Administration (CNSA) mission that launched on September 25, 2008, from the Jiuquan Satellite Launch Center in Gansu Province, China, aboard a Long March 2F rocket. The mission was crewed by Zhai Zhigang, Liu Boming, and Jing Haipeng, who were launched into Low Earth Orbit to conduct a series of spacewalks and scientific experiments. The mission marked a significant milestone in the development of China's space program, following the success of Shenzhou 5 and Shenzhou 6. The crew members were supported by a team of Chinese astronauts and engineers from the China Astronaut Research and Training Center and the Beijing Aerospace Command Center.

Mission Overview

The Shenzhou 7 mission was designed to test the capabilities of the Shenzhou spacecraft and its crew, with a focus on conducting spacewalks and deploying a satellite in orbit. The mission was also intended to demonstrate the ability of the China National Space Administration to launch and recover a crewed spacecraft, and to test the performance of the Long March 2F rocket. The crew members were trained at the China Astronaut Research and Training Center and the Yuri Gagarin Cosmonaut Training Center in Star City, Russia, in preparation for the mission. The mission was supported by a team of NASA and European Space Agency (ESA) experts, who provided guidance and assistance in the areas of spacecraft operations and spacewalk procedures.

Spacecraft Description

The Shenzhou 7 spacecraft was a modified version of the Shenzhou spacecraft, which was designed and built by the China Academy of Space Technology (CAST). The spacecraft consisted of three modules: the reentry module, the service module, and the orbital module. The reentry module was designed to protect the crew during launch and re-entry, while the service module provided power and propulsion for the spacecraft. The orbital module was used for spacewalks and scientific experiments, and was equipped with a airlock and a robotic arm. The spacecraft was launched into Low Earth Orbit by a Long March 2F rocket, which was designed and built by the China Academy of Launch Vehicle Technology (CALT). The spacecraft was also equipped with a communications system developed by the China Electronics Technology Group Corporation (CETC) and a navigation system developed by the China Aerospace Science and Industry Corporation (CASIC).

Crew and Training

The crew of Shenzhou 7 consisted of three Chinese astronauts: Zhai Zhigang, Liu Boming, and Jing Haipeng. The crew members were selected from a pool of Chinese astronauts who had undergone training at the China Astronaut Research and Training Center and the Yuri Gagarin Cosmonaut Training Center in Star City, Russia. The crew members were trained in a variety of skills, including spacewalk procedures, spacecraft operations, and emergency response. The crew was supported by a team of mission control specialists from the Beijing Aerospace Command Center and the China National Space Administration. The crew members also received training from NASA and European Space Agency (ESA) experts, who provided guidance and assistance in the areas of spacecraft operations and spacewalk procedures. The crew was also trained by Russian Federal Space Agency (Roscosmos) experts, who provided training on Soyuz spacecraft operations.

Mission Timeline

The Shenzhou 7 mission was launched on September 25, 2008, at 21:10 UTC from the Jiuquan Satellite Launch Center in Gansu Province, China. The spacecraft reached Low Earth Orbit after a 10-minute ascent, and the crew began to prepare for the first spacewalk. The first spacewalk was conducted by Zhai Zhigang and Liu Boming on September 27, 2008, and lasted for approximately 45 minutes. The crew deployed a satellite in orbit on September 28, 2008, and conducted a series of scientific experiments during the mission. The spacecraft landed safely in Inner Mongolia on September 28, 2008, at 09:37 UTC, marking the successful completion of the mission. The mission was monitored by NASA and European Space Agency (ESA) experts, who provided support and guidance during the mission.

Scientific Experiments

The Shenzhou 7 mission included a variety of scientific experiments, designed to test the effects of microgravity on living organisms and materials. The crew conducted experiments on plant growth, animal behavior, and materials science, using equipment provided by the China Academy of Sciences and the Chinese Academy of Engineering. The crew also deployed a satellite in orbit, which was designed to test the performance of a new propulsion system developed by the China Aerospace Science and Technology Corporation (CASC). The mission included experiments developed by NASA and European Space Agency (ESA) scientists, who collaborated with Chinese scientists to design and conduct the experiments. The experiments were also supported by Russian Federal Space Agency (Roscosmos) and Japan Aerospace Exploration Agency (JAXA) experts, who provided guidance and assistance during the mission. The results of the experiments were analyzed by scientists from the China National Space Administration, NASA, and the European Space Agency (ESA), and were published in a variety of scientific journals, including Nature and Science.
