NASA’s Sofia Telescope Discovers More Water on Lunar Surface


NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA) telescope has found extra water on the Moon’s floor. The recent findings of water have been made within the Southern Hemisphere of the Moon. The analysis was led by Casey Honniball, a postdoctoral fellow at NASA’s Goddard Area Flight Middle. The staff have found water within the Moretus Crater area, which is near the Moon’s Clavius Crater, the place the unique findings have been made. With the brand new statement and availability of complete information, researchers have additionally been in a position to create a map displaying water abundance within the crater.

“If you can find [sufficiently] large concentrations of water on the surface of the Moon – and learn how it’s being stored and what form it’s in – you can learn how to extract it and use it for breathable oxygen or rocket fuel for a more sustainable presence,” said Honniball.

SOFIA, with its Faint Object infraRed Digicam, was in a position to overcome the challenges in differentiating between water

and hydroxyl – a molecule composed of oxygen sure to a single hydrogen atom (OH), in comparison with water’s two hydrogen atoms (H2O). The telescope, which flies above 99 p.c of the water vapour in Earth‘s environment, can see what ground-based telescopes can’t.

SOFIA’s means to tell apart between water and hydroxyl has additionally helped astronomers within the discovery of the idea of how water initially involves the Moon.

“The Moon is constantly being bombarded by the solar wind, which is delivering hydrogen to the lunar surface,” Honniball mentioned. “This hydrogen interacts with oxygen on the lunar surface to create hydroxyl.”

When the Moon is hit by micrometeorites, the excessive temperature of the impression causes two hydroxyl molecules to mix, forsaking a water molecule and an additional oxygen atom. Whereas quite a lot of this fashioned water is misplaced to space, a portion of it will get trapped inside glass fashioned on the Moon’s floor by the impression.

The researchers, utilizing information from SOFIA, have additionally made observations to know the variation of water relying on the Moon’s latitude, composition, and temperature.
