The objective of the Materials International Space Station Experiment (MISSE) is to study the performance of novel
materials when subjected to the synergistic effects of the harsh space environment for several months. In this paper, a
few laser and optical elements from NASA Langley Research Center (LaRC) that have been flown on MISSE 6 mission
will be discussed. These items were characterized and packed inside a ruggedized Passive Experiment Container (PEC)
that resembles a suitcase. The PEC was tested for survivability due to launch conditions. Subsequently, the MISSE 6
PEC was transported by the STS-123 mission to International Space Station (ISS) on March 11, 2008. The astronauts
successfully attached the PEC to external handrails and opened the PEC for long term exposure to the space
environment. The plan is to retrieve the MISSE 6 PEC by STS-128 mission in August 2009.
