An Apollo 11 lunar sample return
The sign accompanying it reads
Lunar Sample Return Container
This sample return container, or "rock box," is one of two used by Apollo 11
astronauts to return 21.6 kilograms (47.7 pounds) of lunar material to the
Earth following the first walk on the Moon, July 20, 1969. The containers are
constructed of aluminum and stainless steel.
After an Apollo lunar module (LM)
descended to the lunar surface, the astronauts took the sample return
containers from a storage compartment in the descent stage. The containers
were then filled with lunar material, sealed, and returned to the ascent stage
of the LM.
The steel mesh pads in the boxes protected the lunar samples from damage during
reentry and splashdown.
