Star Tracker Based Generic Safe Mode for Science Missions

A previous study (TRP Star sensing based safe mode) confirmed the interest of using star tracker as primary sensor in a generic safe mode: versatility, suitability to complex requirements and constraints (e.g.

Detection of microparticle impacts on spacecraft via their plasma effects

Microparticles are one of the most unknown components of the space environment. Their observation and investigation is complicated by their small size and their high velocity. When impacting on a spacecraft surface, a plasma cloud is generated by shock wave and surface ionization processes. This transient cloud of vaporized and ionized particle and surface material, referred to as impact plasma, rapidly expands to the meter scale within microseconds, thereby interacting with spacecraft surface components.

Dusty Plasma Environments: Near-Surface Characterization and Modelling

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."
