Comparative Raman spectroscopy of astrobiology relevant bio‐samples and planetary surface analogs under UV–VIS–IR excitation

Franziska Hanke, Ute Böttger, Andreas Pohl, K. Irmscher et autres

Abstract We investigated the potential of a laser selection in the broad optical range, from ultraviolet through visible to infrared (excitation wavelengths of 325, 532, 785, and 1064 nm) for combined analysis of Earth‐relevant extremophiles (Xanthoria elegans, Buellia frigida, and green alga …

Biosignature stability in space enables their use for life detection on Mars

Mickaël Baqué, Theresa Backhaus, Joachim Meeßen, Franziska Hanke et autres

Two rover missions to Mars aim to detect biomolecules as a sign of extinct or extant life with, among other instruments, Raman spectrometers. However, there are many unknowns about the stability of Raman-detectable biomolecules in the martian environment, clouding the interpretation of …

Space weathering simulation of micrometeorite bombardment on silicates and their mixture for space application

I. Weber, Ute Böttger, Franziska Hanke, Max P. Reitze et autres

Abstract Missions to planetary bodies require innovative techniques for the in situ investigation of their surfaces, especially when landings are planned. Therefore, Raman spectroscopy as an excellent laboratory tool for rapid mineralogical analysis of both terrestrial and extraterrestrial rocks has been successfully …

Raman spectra of the Markovka chondrite (H4)

S. А. Voropaev, Ute Böttger, S. G. Pavlov, Franziska Hanke et autres

Abstract Raman spectroscopy and scanning electron microscopy methods were used to study the fragment of the Markovka (H4 chondrite) meteorite. A characteristic set of silicate minerals (olivine and pyroxene), oxides and hydroxides (maghemite and goethite), troilite, and carbonates (aragonite) was determined. The …

Evaluation of techniques for handling luminescence in Raman spectroscopy for space application in regard to the search for extraterrestrial life

Franziska Hanke

Die Ramanspektroskopie (RS) ist eine analytische Technik, die in Folge einer optischen Anregung eines Stoffes materialspezifische Informationen über dessen molekulare Schwingungen und Kristallstruktur liefert. Da sowohl Minerale als auch biologische Materialien untersucht werden können, ist die RS in der Weltraumforschung von besonderem …

Models of H chondrites genesis and evolution: new findings

BIOLEX – The Biology and Lunar experiment and the LOGOS Cubes

Jean‐Pierre de Vera, Mickaël Baqué, Andreas Lorek, Thomas Berger et autres

BIOLEX is a concept designed for in situ science on the Moon or in its orbit. As heritage of the polar and space experiment BIOMEX (Biology and Mars Experiment) on the ISS it is a more developed concept. Measurement operations on an …

The Raman spectrometer onboard the MMX rover for Phobos

Till Hagelschuer, Tomás Belenguer, Ute Böttger, Maximilian Buder et autres

We present the Raman spectrometer onboard the rover which will be part of JAXAs Martian Moons eXploration (MMX) mission, to be launched in 2024. The Raman for MMX (RAX) instrument is designed to investigate the surface mineralogy of Phobos, according to the …
