Which Houston facility first received Apollo 11's Moon rocks for examination?

The Lunar Receiving Laboratory first received Apollo 11’s Moon rocks for examination. NASA built the Houston facility to quarantine the astronauts and lunar material while scientists checked for possible biological hazards and began studying the samples.

After splashdown and recovery, the crew entered quarantine, and the lunar samples were transported to Houston. Inside the laboratory, researchers initially handled the rocks and regolith in sealed glovebox chambers, using controlled conditions to reduce contamination and protect both Earth and the specimens.

The facility also became a center for distributing lunar material to investigators. Apollo 11 returned about 21.5 kilograms of lunar samples, including basalt, breccia, soil, and dust. The rocks helped establish that the Moon had experienced ancient volcanic activity and intense impact history.

The Lunar Receiving Laboratory is often confused with the later Lunar Sample Laboratory Facility. The latter, opened in 1979, became the principal long-term repository; the LRL was the original quarantine, receiving, and early-analysis facility.
