A new class of Martian impact craters have been discovered, by Northern Arizona University scientists from which public, co-educational college and university?
LARLE crater A new class of Martian impact craters have been discovered by Northern Arizona University scientist Prof Nadine Barlow and Dr Joseph Boyce from the University of Hawaii in Oct 2013. They have termed it as ‘low-aspect-ratio layered ejecta (LARLE) craters’. Prof Nadine Barlow, a scientist Northern Arizona University described this class of craters with “thin-layered outer deposit” surpassing “the typical range of ejecta”. “The combination helps vaporize the materials and create a base flow surge. The low aspect ratio refers to how thin the deposits are relative to the area they cover,” Prof Barlow said. The scientists used data from continuing reconnaissance of Mars using the old Mars Odyssey Orbiter and the Mars Reconnaissance Orbiter, discovered 139 LARLE craters ranging in diameter from 1.0 to 12.2 km, with 97 per cent of the LARLE craters are found poleward of 35N and 40S, while remaining mainly traced in the equatorial Medusae Fossae Formation.
Priestley (Martian crater) Priestley is an impact crater in the Eridania quadrangle of Mars, located at 54.4°S latitude and 229.4°W longitude. It measures 41.9 kilometers in diameter and was named after English clergyman and scientist Joseph Priestley. The naming was approved by IAU's Working Group for Planetary System Nomenclature in 1973.
