Lunar Receiving Laboratory
The Lunar Receiving Laboratory opened its doors in 1969 with a single, terrifying goal. Scientists feared that the Moon might harbor unknown pathogens capable of infecting Earth's biosphere. This fear drove the construction of Building 37 at NASA's Lyndon B. Johnson Space Center. The facility was designed to isolate both astronauts and lunar rocks immediately upon their return from space. Apollo 11 crews walked from their helicopter directly into a Mobile Quarantine Facility on an aircraft carrier deck. They then traveled to Houston for strict isolation procedures. No one knew what microscopic life might be hiding in the lunar dust.
Six Apollo missions delivered 382 kilograms of material between 1969 and 1972. These shipments included 2,200 distinct samples collected from six different exploration sites. Astronauts brought back lunar rocks, core samples, pebbles, sand, and fine dust. The agency flew these precious cargo items directly to the laboratory for initial analysis. Technicians examined the specimens inside glovebox vacuum chambers to prevent any contamination. The operation required immense logistical coordination across multiple government agencies. Every gram of rock received careful handling within the sterile environment.
Three automated Soviet spacecraft returned smaller quantities of regolith to the same facility. Luna 16 arrived with its payload in 1970. Luna 20 followed suit in 1972. Luna 24 completed the trio by returning samples in 1976. These three missions collectively brought back only 300 grams of lunar soil. That amount represented roughly three-quarters of a pound compared to the American haul. Scientists studied these foreign samples alongside the much larger Apollo collection. The comparison provided valuable data on the composition of the lunar surface.
The year 1976 marked a significant shift in how NASA managed its lunar inventory. Officials decided to move part of the sample collection to Brooks Air Force Base in San Antonio. This location served as a second-site storage option for safety reasons. A new Lunar Sample Laboratory Facility opened in 1979 to become the chief repository for Apollo samples. This permanent home included vaults designed for secure and non-contaminating storage. The older building at Johnson Space Center would eventually see different uses.
Building 37 transitioned from a quarantine zone into a hub for biomedical research. NASA's Life Sciences division took over the structure after sample storage moved elsewhere. The facility contained laboratories dedicated to studying human adaptation to microgravity. Researchers conducted experiments involving environmental factors within the converted space. The original purpose of isolating potential Moon pathogens faded into history. The building now focused on understanding how humans survive in low gravity environments.
September 2019 brought news that the Lunar Receiving Laboratory was no longer needed. NASA confirmed the structure had sat unused for two years prior to this announcement. The agency declared plans to demolish the historic building shortly thereafter. This decision ended decades of service for the facility originally built to protect Earth. The physical destruction marked the final chapter of an era defined by lunar exploration fears.
