Themobile quarantine facility (MQF) was a convertedAirstream trailer used byNASA toquarantineastronauts returning fromApollo lunar missions for the first few days aftersplashdown. The MQF was on the aircraft carrier that picked up the capsule. Once the aircraft carrier reached port, the MQF was flown to Houston, and the crew spent the remainder of the 21 days of quarantine in theLunar Receiving Laboratory at the Manned Spacecraft Center. The purpose of the quarantine was to prevent the spread of anycontagions from the Moon, though the existence of such contagions was considered unlikely. It functioned by maintaining a lower pressure inside and filtering any air vented.^[1]

In June of 1967, NASA awarded contract to design and build the four MQF's to Melpar, Inc., ofFalls Church, Virginia. Lawrence K. Eliason was the head project manager.

The MQF contained living and sleeping facilities as well as communications equipment which the astronauts used to converse with their families. TheApollo 11 crew also used this equipment to speak withPresident Nixon, who personally welcomed them back to Earth in July 1969 aboard the recovery shipUSSHornet after splashdown.

The trailers housed the three crew as well as a physician,William Carpentier, and an engineer,John Hirasaki, who ran the MQF and powered down the command module.

Four MQFs were built for NASA:

The quarantine requirement was eliminated following Apollo 14 once it was proven the Moon was sterile and that the facilities were therefore unnecessary.^[5]
