Before this, Fuglesang also supported the mission's first EVA, during which the EuTEF payload package, which had been installed on an external pallet of ESA’s Columbus Laboratory module in February 2008, was removed and transferred to Discovery’s payload bay. The European Technology Exposure Facility consists of a set of nine experiments that were exposed to the vacuum of space to test materials and equipment, monitor the space environment and take pictures of the Earth below. Throughout its 18 months in space, EuTEF has been under the continuous control of the Erasmus User Support and Operations Centre at the Agency’s European Space Research and Technology Centre (ESTEC) in Noordwijk, the Netherlands. Its samples and instruments will now be returned to the science teams for further analysis.
