ISS Science for Everyone

Science Objectives for Everyone
The objective of Spores in Artificial Meteorites (EXPOSE-R SPORES) is to study the survival of spores of bacteria (Bacillus subtilis), fungi (Trichoderma koningii) and ferns (Athyrium filix-femina, Dryopteris filix-mas) to the space environment as if on a simulated space journey on a meteorite. The EXPOSE programme is part of ESA’s research in astrobiology, i.e. the study of the origin, evolution and distribution of life in the universe. EXPOSE offers one to two years of exposure with full access to all components of the harsh space environment: cosmic radiation, vacuum, full-spectrum solar light including UV-C, freezing/thawing cycles, microgravity.

Experiment Description

Research Overview

The main objective of Spores in Artificial Meteorites (EXPOSE-R SPORES) is to study the survival of spores of bacteria (Bacillus subtilis), fungi (Trichoderma koningii) and ferns (Athyrium filix-femina, Dryopteris filix-mas) on a simulated space journey via meteorites. This includes the study of their resistance against space conditions, i.e. solar UV, vacuum and cosmic radiation, as well as the degree of protection by meteorite material. In addition, the experiment includes the dosimetry package R3D-R for on-line measurement of UV and cosmic radiation and transmission by telemetry.

Applications

Space Applications
EXPOSE-R contains a variety of biological samples including plant seeds, bacteria, fungi and ferns, which are exposed to the harsh space environment for 22 months.

Earth Applications
New knowledge about the origin, evolution, and distribution of life in the universe is expected to be the major benefit of this investigation.

Operations

Operational Requirements and Protocols

At the end of the 22 months exposure period the EXPOSE-R trays are retrieved from their location outside the station and returned to Earth and distributed to scientists for further analysis.

Nine experiments contained in three trays make up EXPOSE-R, which is mounted on the outside of the Russian segment of the International Space Station.
