Astrobiology Space Simulation facilities (ABYSS)

Facilities for the simulation of environmental factors of free space and on planetary surfaces

The general Astrobiological question deals with the understanding of life and the processes that lead to its origin, evolution and distribution on Earth and beyond, as part of cosmic evolution.

In this context the fully equipped and monitored Planetary and Space Simulation facilities allow a broad range of tests with biological and chemical material individually or integrated into space hardware. In the focus of interest are defined and controlled conditions like ultra high vacuum, gas compositions, low and high temperature limits, temperature oscillations, extraterrestrial UV radiation and x-ray.

The analysis of these exposure tests contribute to a deeper under-standing of the individual and synergistic effects of space with the exposed material. In this way they support the design optimisation and verification of spacecraft devices and the selection of the most promising biological candidates and chemical compositions for flight experiments in low Earth orbit or other space destinations.

All of the simulation facilities are necessary:

  • for testing of newly developed space hardware
  • for investigating the effect of different space parameters on biological systems as preparation for flight experiments
  • for performing the "Experiment Verification Tests" (EVT) for the specification of the test parameters
  • for performing the "Science Verification Tests" (SVT) by simulating sample assembly, exposure to expected space parameters and sample disassembly
  • for the performance of the ground control experiment "Mission Ground Reference Test" (MGR) under simulated space conditions, by parallel exposure of samples to simulated space parameters according to flight data received e.g. by telemetry.

The Astrobiology Space Simulation facilities allow the investigation of a much wider variety of samples than in space experiments. These simulation chambers offer the possibility to discriminate between the effects of individual space parameters and selected combinations. The experiments already performed proofed the outstanding importance and accentuated need for mission preparation and mission ground reference tests for every space mission. In this way they enable a better ground to space prediction.

For every need, the simulation facilities are adapted, sometimes resulting in the complete conveyance of a facility in a new one. Therefore, the numbers of the facilities are historically founded and not successive.

Deep Space 1 (PSI 3)


Deep Space 1 (PSI 3) is a vertically orientated facility. It provides the possibility of simultaneous radiation exposure of a moderate amount of samples and their corresponding dark references on four stacked and linked copper cooling plates. They guarantee a consistent temperature for both sample layers. Radiation is conducted with polychromatic light emitted from metal halogenide solar simulators (1000 W / 2000 W). A variety of neutral density filters and cut-off filters are available.
