BIOMEX: Biology and Mars Experiment

General information:

  • Experiment on EXPOSE-R2 attached outside on the Zvezda module of the International Space station (ISS)
  • Launch: scheduled for April 2014
  • biological and mineralogical samples on EXPOSE-R2
  • biological and mineralogical samples in Ground Simulation facilities of DLR Cologne/Berlin (Environmental Verification Tests EVT and Scientific Verification Tests SVT, in DLR Cologne, Mars simulation facility (MSF-T tests as adds on at the DLR Berlin)

Scientific objectives of BIOMEX

The prime objective of BIOMEX is to measure to what extent biomolecules like pigments and cell components are resistant to and able to maintain their stability under space and Mars-like conditions. The results of BIOMEX will be relevant for space proven biosignature definition and the formation of a biosignature data base (e.g. the proposed creation of an international Raman / UV/VIS/IR spectroscopy library). The library would be useful for future space missions like projects for life detection analysis on Mars (e.g. ExoMars).

The secondary scientific objective is to analyze to what extent terrestrial extremophiles are able to survive in space and which interaction between biological samples and selected minerals (including terrestrial, Moon- and Mars analogue varieties) can be observed under space and Mars-like conditions. The results will provide new information about environmental extremes that can be sustained by the proposed species and about the chances for survival during a ‘natural’ trip in space (according to the Panspermia theory). The BIOMEX samples will consist of a variety of pigments, cell wall components, lichens, archaea, cyanobacteria, iron bacteria, snow alga, black fungi and bryophytes.

In brief these and other scientific objectives are in focus within the BIOMEX-mission as listed below:

BIOSIGNATURES

  • Stability / degradation of space exposed biomolecules and organisms in contact to natural / Mars analogue substrates
  • Interaction between bio-samples and natural / Mars/Lunar analogue substrates.
  • Collect information for a biosignature reference data base (Raman, UV/VIS, IR- and MS-Spectroscopy).

HABITABILITY OF MARS

  • Capacity of organisms to resist, survive and live under Mars-like / space exposure conditions

LITHOPANSPERMIA

  • Likelihood of Lithopanspermia hypothesis with new organisms (compared to EXPOSE-E)

IMPROVE INS-SITU SCIENCE ON THE ISS

  • Improve environmental sensors (gas pressure, humidity, temperature, radiation)

SUPPORT OF EXPLORATION MISSIONS

  • The search for life on Mars and other planets and satellites with different methods of spectroscopy (Raman, UV/VIS, IR- and MS-Spectroscopy)

Space parameters in Low Earth Orbit as expected for BIOMEX
