The multi-user facility EXPOSE-E was designed by the European Space Agency to enable astrobiology research
in space (low-Earth orbit). On 7 February 2008, EXPOSE-E was carried to the International Space Station (ISS) on
the European Technology Exposure Facility (EuTEF) platform in the cargo bay of Space Shuttle STS-122 Atlantis.
The facility was installed at the starboard cone of the Columbus module by extravehicular activity, where it
remained in space for 1.5 years. EXPOSE-E was returned to Earth with STS-128 Discovery on 12 September 2009
for subsequent sample analysis. EXPOSE-E provided accommodation in three exposure trays for a variety of
astrobiological test samples that were exposed to selected space conditions: either to space vacuum, solar
electromagnetic radiation at > 110nm and cosmic radiation (trays 1 and 3) or to simulated martian surface
conditions (tray 2). Data on UV radiation, cosmic radiation, and temperature were measured every 10 s and
downlinked by telemetry. A parallel mission ground reference (MGR) experiment was performed on ground
with a parallel set of hardware and samples under simulated space conditions. EXPOSE-E performed a
successful 1.5-year mission in space
Automated payload and instruments for astrobiology research developed and studied by German medium-sized space industry in cooperation with European academia
For more than a decade Kayser-Threde, a medium-sized enterprise of the German space industry, has been involved in
astrobiology research in partnership with a variety of scientific institutes from all over Europe. Previous projects include
exobiology research platforms in low Earth orbit on retrievable carriers and onboard the Space Station. More recently, exobiology
payloads for in situ experimentation on Mars have been studied by Kayser-Threde under ESA contracts, specifically the ExoMars
Pasteur Payload. These studies included work on a sample preparation and distribution systems for Martian rock/regolith samples,
instrument concepts such as Raman spectroscopy and a Life Marker Chip, advanced microscope systems as well as robotic tools
for astrobiology missions. The status of the funded technical studies and major results are presented. The reported industrial
work was funded by ESA and the German Aerospace Center (DLR)
EXPOSE, an Astrobiological Exposure Facility on the International Space Station - from Proposal to Flight
Following an European Space Agency announcement of opportunity in 1996 for
”Externally mounted payloads for 1st utilization phase” on the International Space Station
(ISS), scientists working in the fields of astrobiology proposed experiments aiming at longterm
exposure of a variety of chemical compounds and extremely resistant microorganisms
to the hostile space environment. The ESA exposure facility EXPOSE was built and an
operations´ concept was prepared. The EXPOSE experiments were developed through an
intensive pre-flight experiment verification test program. 12 years later, two sets of
astrobiological experiments in two EXPOSE facilities have been successfully launched to
the ISS for external exposure for up to 1.5 years. EXPOSE-E, now installed at the balcony
of the European Columbus module, was launched in February 2008, while EXPOSE-R
took off to the ISS in November 2008 and was installed on the external URM-D platform of
the Russian Zvezda module in March 2009
