The main goals of the DPEM project was [RD1] "to set the foundations for the development of a comprehensive suite of near surface dusty plasma environment models applicable in particular (but not only) to airless bodies of interest for future exploration missions such as asteroids, the Moon, Phobos and Deimos, etc … These models shall allow the definition of charged dust environment specifications to assess the effects of dusty plasmas on near surface or surface exploration units (spacecraft, payload, lander, astronaut) in a surface-spacecraft-dust environment system."
