Abstract

Spaceagenciesworldwideareseekingpromisinganalyticaltoolsor
novel combinations of established techniques to broaden our understanding of
extraterrestrial processes. The constraints for extraterrestrial missions are quite

(DAG 400), which was found in 1998 in the respective meteorite field in the
Libyan Sahara, is utilized as a model for extraterrestrial research employing
MössbauerandRamanspectroscopy.Inaddition,opticalandX-raymicroscopic

Mössbauer spectroscopy, the miniaturized Mössbauer spectrometer MIMOS II,
which has already gained recognition in extraterrestrial research on Mars, was
