- Abstract
Space debris poses increasing threat to the orbiting spacecraft. Chinese government has been funding space debris projects systemically for a number of years, and some developments have been achieved in several fields. The government has made a long term commitment to the development of the space debris research. In the space debris protection field, China needs to enhance the infrastruction, extend the research scope, emphasize the engineer application and boost the international communication. Detailed plan is as follows: (1) A series of two-stage-gas gun will be constructed, equipped with the integrated diagnosis and measurement facilities, in order to get the complete hypervelocity impact characters. (2) Other kinds of facilities including plasma accelerator, electrostatic accelerator and laser accelerator, which will be used to simulate micron size to sub-millimeter size particle impact effect, will be constructed in order to get long-term accumulating effect of micro-particle impact on the component/subsystem. (3) Developing BLEs systemically in order to establish the database which includes several Whipple shield structures and the exposure structures of spacecraft. (4) Aiming at some important components/subsystems in the spacecraft, explore the reasons of the malfunction and failure due to hypervelocity impact, establish the relative failure modes database. (5) Based on the above achievements, provides risk assessment service for the manned spacecraft and all kinds of satellites, including a series of standards and codes which will be used to instruct the engineer applications. (6) According to the IADC frame, the communication between other countries and China will be strengthened in order to keep mutual development.
