Ambient space plasma can induce electrostatic noise in a linear antenna onboard a spacecraft. The resulting quasi-thermal noise (QTN) intensity spectrum as a function of frequency depends on the plasma parameters. The phenomenon can be utilised for inferring the plasma parameters if one measures the induced noise by a sensitive radio receiver. This is called QTN spectroscopy and it has been demonstrated and validated in several space missions that the technique is able to uncover the correct plasma parameters.

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."
