Bang and Whoosh! This HiRISE image from NASA’s Mars Reconnaissance Orbiter (MRO) captures a new, dated (within about a decade) impact crater that triggered a slope streak. When the meteoroid hit the surface and exploded to make the crater, it also destabilized the slope and initiated this avalanche. The crater…View More Bang and Whoosh!
NASA Encounters the Perfect Storm for Science One of the thickest dust storms ever observed on Mars has been spreading for the past week and a half. The storm has caused NASA’s Opportunity rover to suspend science operations, but also offers a window for four other spacecraft to learn from…View More NASA Encounters the Perfect Storm for Science
Opportunity Hunkers Down During Dust Storm NASA Mars Exploration Rover Status Report Updated at 4:30 p.m. PDT on June 10, 2018 NASA engineers received a transmission from Opportunity on Sunday morning — a positive sign despite the worsening dust storm. Data from the transmission let engineers know the rover still…View More Opportunity Hunkers Down During Dust Storm
Patches of Snow on the Red Planet In early Martian summer, at the time NASA’s Mars Reconnaissance Orbiter acquired this image, the dunes are almost free of their seasonal ice cover. Only pockets of ice protected in the shade most of the day remain. The North Pole of Mars is…View More Patches of Snow on the Red Planet
Small Troughs Growing on Mars May Become ‘Spiders’ Erosion-carved troughs that grow and branch during multiple Martian years may be infant versions of larger features known as Martian”spiders,” which are radially patterned channels found only in the south polar region of Mars.Researchers using NASA’s Mars Reconnaissance Orbiter (MRO) report the…View More Small Troughs Growing on Mars May Become ‘Spiders’
Some Ancient Mars Lakes Came Long After Others Lakes and snowmelt-fed streams on Mars formed much later than previously thought possible, according to new findings using data primarily from NASA’s Mars Reconnaissance Orbiter. The recently discovered lakes and streams appeared roughly a billion years after a well-documented, earlier era of…View More Some Ancient Mars Lakes Came Long After Others
