Maybe it is a rose by any other name, but at some point something smacked into our only natural satellite and ended up blowing dust and rock for about 1.4 miles (2.2 km), leaving in its wake a lovely flower pattern. The image was captured by the Lunar Reconnaissance Orbiter, which has been circling the Moon since 2009.
Such impacts on the Moon do not erode as fast as they would on an atmosphere bearing body, but in time they do fade due to solar wind activity, thermal movement, and impacts from other meteorites. So that puts this Lunar display relatively new – but still think in terms of eons, not years.
Lunar Reconnaissance Orbiter
The Lunar Reconnaissance Orbiter (LRO) is a NASA robotic spacecraft currently orbiting the Moon on a low 50 km polar mapping orbit.[1] The LRO mission is a precursor to future manned missions to the Moon by NASA. To this end a detailed mapping program will identify safe landing sites, locate potential resources on the Moon, characterize the radiation environment, and demonstrate new technology.
