A lunar rock fragment was sent to Biden's Government Office on January 20 local time. At the request of the president of the United States, NASA delivered a container containing lunar rock samples for display in the Oval Office. This rock from the earth's neighbor is placed in the White House, symbolizing recognition of the ambitions and achievements of our predecessors, as well as support for us exploration of the moon and Mars.

The inscription goes on: "this 332 gram piece of lunar debris (less than a pound) was collected in 1972 and is a 3.9 billion year old sample formed in the imbrim impact basin (1145 km or 711.5 miles in diameter), the last major impact event near the moon.". In this sample, the flat part was sawn by NASA's lunar finishing laboratory as it sliced for scientific research. The rest is relatively natural - just as rocks are captured on the moon.
