EXPORT

Payload

• EXPOSE was a facility holding multiple exobiology experiments that study the photo-processing of organic molecules and the survival of micro-organisms in space, as well as the effect of solar UV on unshielded organic molecules and micro-organisms. The EXPOSE experiment had 12 sample compartments; each held a sample carrier. EXPOSE was placed in 2008 on an external platform on the Columbus – External Payload Facility where it remained for 1.5 years.
• The second instrument, Sky Polarization Observatory, was an Italian astrophysical instrument to measure celestial polarisation range of 20–90 GHz. SPOrt goals included the first polarisation map of the Milky Way galaxy at the unexplored microwave frequencies of 22, 32 & 60 GHz and all-sky measurements in the cosmological window with unprecedented sensitivity. However, due to the project's reliance on the Space Shuttle, and the setback of the Columbia disaster, the observatory was canceled in 2005.
