Abstract On September 7th, 2017 the U.S. Air Force Research Laboratory launched the second Advanced Structurally Embedded Thermal Spreader (ASETSII) flight experiment to space on Orbital Test Vehicle 5. The ASETS-II experiment is made of three low-mass, low-cost oscillating heat pipes (OHPs)
and an electronics/experiment control box. The three primary science objectives of the experiment are to measure the initial on-orbit thermal
performance, to measure long duration thermal performance, and to assess any lifetime degradation. The three OHPs on ASETS-II are of varying
configuration (center heating with single- and double-sided cooling) and working fluids (butane and R-134a) in order to isolate… More >
