Photographic documentation of Payload Commander and Mission Specialists Bernard Harris, Jr. conducting Gas-Permeable Polymeric Materials (GPPM) tests on the Space Shuttle Discovery's SPACEHAB during STS-63. For GPPM experimentation monomers and activators were mixed in a commercial refrigerator/incubator module to form membranes that can be permeated by gas. Includes views of MS Harris posing with the GPPM operations checklist (024-025).
