‘Impact Melt Breccia’: Scientists reveal mystery behind gel-like substance on lunar surface
New Delhi | Jagran Trending Desk: A year after China’s mission Yutu-2 rover brought a piece of fascinating news for the astronomers about the presence of a gel-like substance in a crater on the far side of the Moon, researchers at the Chinese Academy of Sciences have now published a detailed analysis of the substance found last year in August.
Published in the journal Earth and Planetary Science Letters, the detailed analysis by the researchers of Chinese Academy of Sciences, revealed that the gel-like substance found in the crater on the lunar surface is a rock, more precisely an ‘impact melt breccia’.
The analysis further stated that the breccia or the composition of rock fragments transformed into gel-like substance after melting likely in the heat after a meteorite impact and have tuned to glossy, glassy and dark green mass over the years.
In another revelation, the analysis stated that the dark green, glassy gel-like substance is similar to the two samples, which were earlier classified as breccia and were retrieved by the Apollo 15 and 17 missions, Lunar Sample 15466 and Lunar Sample 70019.
The researchers explained in their paper, “Chang’e-4 rover discovered a dark greenish and glistening impact melt breccia in a crater during its traverse on the floor of Von Kármán crater within the South Pole Aitken (SPA) basin on the lunar far side.”
The images of the gel-like glassy dark green substance was captured by China’s Yutu-2 rover using its panoramic camera and the Visible and Near-Infrared Imaging Spectrometer (VNIS), for detailed analysis in August last year. The Yutu-2 rover was sent on the Lunar surface as a part of China’s Chang’e 4 lunar lander mission.
