On July 26, 1972, Robert Crippen, Karol "Bo" Bobko, and Dr. William Thornton began the Skylab Medical Experiment Altitude Test (SMEAT), 56 days inside a vacuum chamber at the Manned Spacecraft Center in Houston, Texas. Their mission was to evaluate the equipment and procedures for use aboard the United States' first space station, Skylab.

This beta cloth small trash bag (P/N: SEC12100229-301, Ser. No. 1014) was manufactured by General Electric, Co. for NASA in March 1972. Its NASA Spacecraft Parts Tag indicates it was removed from SMEAT in September 1972. It remains to this day hermetically sealed and "cleaned for service" as it was November 16, 1973.

The above image shows Skylab 4 crewmembers passing a similar trash bag as was installed for the SMEAT mission.
