Summary Description:

 

Knowledge on the meteoroid and space debris environment is required for a reliable spacecraft risk assessment and for the design of protective shielding. At present our models still have large uncertainties. Particles larger than a few cm in diameter can be detected by radar or optical telescopes from the ground.

 

Information on the small-size (sub-millimeter) meteoroid and space debris environment can only by gained by the analysis of retrieved spacecraft or by in-situ monitors in orbit. For orbits above 600 km retrieval of space hardware is not possible and active monitors are required to measure impacting fluxes, their seasonal variations and long term evolution.

 

A standard low resources meteoroid and space debris in-situ impact detector (DEBIE-1) will be developed and build. The detector will actively monitor sub-millimeter sized particles which impact the detector surfaces. The instrument will consist of a central processing unit and up to 4 separate sensor units which can be placed on different spacecraft surfaces. DEBIE-1 will use a combination of impact ionisation, momentum and foil penetration detection. The instrument will be designed as a standard detector which can be flown on different spacecraft and missions with little or no modifications.

 

The first flight of DEBIE-1 was scheduled for the PROBA mission (end of 1999 or in 2000).

A second DEBIE (DEBIE-2) will be placed on the International Space Station as external payload.
