(英语)NASA Lends Moon Rock for Oval Office Display
In symbolic recognition of earlier generations’ ambitions and accomplishments, and support for America’s current Moon to Mars exploration approach, a Moon rock now sits in the Oval Office of the White House. At the request of the incoming Biden Administration, NASA loaned the Moon rock that was put on display in the Oval Office Jan. 20. It is from the Lunar Sample Laboratory Facility at NASA’s Johnson Space Center in Houston, and its display case is inscribed with the following:
Lunar Sample 76015,143
Apollo 17 astronaut Ronald Evans and moonwalkers Harrison Schmitt and Eugene Cernan, the last humans to set foot on the Moon, chipped this sample from a large boulder at the base of the North Massif in the Taurus-Littrow Valley, 3 km (almost 2 miles) from the Lunar Module. This 332 gram piece of the Moon (less than a pound), which was collected in 1972, is a 3.9-billion-year-old sample formed during the last large impact event on the nearside of the Moon, the Imbrium Impact Basin, which is 1,145 km or 711.5 miles in diameter.
The irregular sample surfaces contain tiny craters created as micrometeorite impacts have sand-blasted the rock over millions of years. The flat, sawn sides were created in NASA’s Lunar Curation Laboratory when slices were cut for scientific research. This ongoing research is imperative as we continue to learn about our planet and the Moon, and prepare for future missions to the cislunar orbit and beyond.
