Apollo and Skylab astronauts had this kit to make minor repairs to their Extravehicular Mobility Units (EMUs, or spacesuits). This kit was aboard the Apollo 11 command module during its lunar mission, July 16-24, 1969. The kit contains cloth tape, exterior patches, sealant bladder repair material, optical surface cleaning and defogging pads, and replacement gaskets. The command and lunar modules carried such kits on all of the Apollo Moon missions.
