At present

Chinese "Shenzhou" manned space program

lunar exploration project

the station space program

etc have made a great progress

thus charging and discharging effects during launch and orbit operation have become an important source of electromagnetic hazards to spacecraft

the study on these effects and their protection is one of important tasks affecting the reliability and safety of the spacecraft. Consequently

we discuss some aspects of spacecraft electrostatic hazards research

including the hazards of charging and discharging effects to spacecraft

mechanism of charging and discharging effects

and protection technology. Based on system analysis of some new problems and new research demand of spacecraft

the research prospect and development trend are expounded. The results show that the research of spacecraft charging-discharging effects and their protection focuses on new theory and technology

new environment

new technology

new platform

new requirements

and new load. The next key research contents will include ground multi-source integrated simulation technology

on-orbit monitoring technology

new electrostatic effects and new electrostatic application in the space

and these new technologies can provide support for the reliability and safety of the spacecraft.
