The installation of ESA's TPX-II Two-Phase Flow Experiment as Get Away Special G-467 in the Shuttle Orbiter Discovery for the STS-95 mission. Launch occurred 29 October 1998; landing was 7 November 1998. ESA Mission Specialist Pedro Duque made his first spaceflight on this mission. TPX-II was part of ESA's Technology Development Programme (TDP). Its overall objective was an in-orbit demonstration of the working principle of a 2-phase Capillary Pumped Loop for heat transport, and to assess its performance. TPX-II was a follow-up to TPX-I, flown as G-557 aboard STS-60 in February 1994. The main contractor for both versions was the Dutch National Aerospace Laboratory (NLR); subcontractor was SABCA of Belgium. [Image Date: 1998/09] [98.09.011-004]
