Latest Martian Gullies Stories
Vesta, the propoplanet visited by NASA’s Dawn spacecraft from 2011 through 2013, may have once been home to short-lived flows of water-mobilized material – a discovery which could have tremendous implications for the field of planetary science, according to the US space agency.
NASA’s Mars Reconnaissance Orbiter (MRO) continually makes high-resolution observations of the surface of Mars. Recent images have revealed that the gullies on the surface are mainly formed by seasonal freezing of carbon dioxide and not liquid water.
WASHINGTON, July 10, 2014 /PRNewswire-USNewswire/ -- Repeated high-resolution observations made by NASA's Mars Reconnaissance Orbiter (MRO) indicate the gullies on Mars' surface are primarily
Well preserved gullies and debris flow deposits in a crater on the southern hemisphere of Mars are providing new evidence through their geomorphological attributes that they were formed by the action of liquid water in relatively recent geological times.
Hunks of dry ice – carbon dioxide – may glide down Martian sand dunes like miniature hovercraft, riding on cushions of gas and plowing furrows as they go, according to new research from NASA.
NASA launched the Dawn Mission in 2007 to study the giant asteroid Vesta and dwarf planet Ceres. New images from Vesta reveal oddities that seem almost water-like.
Though Mars is 140 million miles away, it shares some similarities with Earth. Some of its landforms, for existence, closely resemble regions found here on Earth.
