Gas Permeable Polymer Materials (GPPM)

The Gas Permeable Polymeric Materials (GPPM) payload was sponsored by the Instrument Research Division, NASA Langley Research Center (LaRC), through
a joint NASA/industry program initiated in 1987 with the NASA Office of Advanced Concepts and Technology. This polymer study program will determine if
certain types of polymers made in microgravity are very different from the same polymers made simultaneously on the ground.
