Interplanetary Micrometeoroid Environment for eXploration (IMEX, NEMS)

The approach of the ‘Interplanetary Meteoroid Environment for eXploration’ (IMEX) project is to build a model of meteoroid streams throughout the inner solar system. Our motivation for this model is the impact hazard to spacecraft. An understanding of the interplanetary environment, including the dust environment, is crucial for the planning of spacecraft missions in the inner solar system. Particles striking a spacecraft with high velocities can cause damage leading to the impairment or even failure of the spacecraft or its subsystems.

Perspective of Solar Pumping of Solid State Lasers for ESA Missions

The use of lasers for space missions has been increasing in the past and will dramatically increase in the future. Lasers in space often fulfill tasks that cannot be accomplished by other means. Examples are measuring distances of millions of kilometers with nanometer precision, detecting trace gases in the atmosphere of Earth from a satellite, or transmitting data between satellites over distances of some 10,000 km at very high rates. With the exception of semiconductor lasers, almost all of the la- sers used in space are optically pumped solid state lasers.

Atom Interferometry Test of the Weak Equivalence Principle in Space

The Atom Interferometry Test of the Weak Equivalence Principle in Space (Q-WEP) is devoted to a precise measurement of the effect of gravity on matter using an atom interferometer; it tests one of the fundamental pillars of Einstein’s Theory of General Relativity with high precision and thereby searches for hints of quantum effects in gravity, contributing to the exploration of one of the current frontiers in fundamental physics.
