According to statistics, up to now, more than 5000 spacecrafts have been launched and up to 2010, there will be 2000 satellites operating on the earth orbits. Like land and ocean, space has become an indispensable part in human beings’ life. Chinese Society of Astronautics:  Chinese Society of Astronautics China’s Space Activities A comprehensive space industry system of research, design, production and testing has been formed. Various types of launch vehicles and satellites have been developed and manufactured. Space launching centers have been established. A space TT&C network has been in place. A number of satellite application systems have been set up. Chinese Society of Astronautics:  Chinese Society of Astronautics Challenges human beings are facing when exploring space If space is weaponrized, space assets of all countries will be endangered and international peace and security will be threatened. With the frequent space activities, more and more space debris will be accumulated, which is severely endangering the near earth spacecrafts and threatening the security of ground life and asset. Some space environment factors, such as upper atmosphere, high energy charged particles and etc will greatly damage spacecrafts and astronauts traveling in space. That how governments supervise activities of private enterprises and how the international responsibilities be shared are issues which will affect the healthy development of space activities. Chinese Society of Astronautics:  Chinese Society of Astronautics Measures China has taken to meet challenges Space debris research Since 1990, China has started space debris mitigation work. China has independently developed space debris early warning system; primarily established small scale space debris database; mastered spacecraft launch and on-orbit running collision early warning technology; established super speed collision basic equipment; possessed computer simulation capability; basically solved passivation of the current launch vehicle; worked out “ list of Standard Frame System of Space Debris” and “Action Plan of Space Debris (2006~2020) . Chinese Society of Astronautics:  Chinese Society of Astronautics Space environment research Space environment exploration research China’s space environment exploration research focuses on the study of space environment and its effects on spacecraft. The exploration consists of probing and monitoring high energy electron, proton and heavy ion and their single event effect and radiation dose effect, hot plasma and its charging effect, upper atmosphere density and composition and etc. The research also includes the ground simulation experiment of space environment and its effects and laboratory study of protective measures against harmful space environment effects. 1996, China published “LEO Spacecrafts Space Environment Brochure”.
