Researchers claim Mojave Crater on Mars is source of Mars rocks found on Earth
Gusev Crater once held a lake after all, Mars scientist says
(Phys.org) —If desert mirages occur on Mars, "Lake Gusev" belongs among them. This come-and-go body of ancient water has come and gone more than once, at least in the eyes of Mars scientists.
Study rebuts hypothesis that comet attacks ended 9,000-year-old Clovis culture
(Phys.org)—Rebutting a speculative hypothesis that comet explosions changed Earth's climate sufficiently to end the Clovis culture in North America about 13,000 years ago, Sandia lead author Mark Boslough ...
Study: Martian crater may once have held groundwater-fed lake
(Phys.org)—A NASA spacecraft is providing new evidence of a wet underground environment on Mars that adds to an increasingly complex picture of the Red Planet's early evolution.
Curiosity rover finds old streambed on Martian surface
(Phys.org)—NASA's Curiosity rover mission has found evidence a stream once ran vigorously across the area on Mars where the rover is driving. There is earlier evidence for the presence of water on Mars, ...
Mars rover Curiosity beams back images showing its descent
(Phys.org) -- Earlier today, just hours after NASA's Curiosity rover landed on Mars, a select group of images taken by the onboard Mars Descent Imager, or MARDI, were beamed back to Earth. The 297 color, low-resolution ...
Curiosity rover finds clues to changes in Mars' atmosphere
(Phys.org)—NASA's car-sized rover, Curiosity, has taken significant steps toward understanding how Mars may have lost much of its original atmosphere.
New computer simulations reveal possible violent history of giant asteroid Vesta
Mars crater may actually be ancient supervolcano, study says
(Phys.org) —A research project led by Joseph R. Michalski, Senior Scientist at the Planetary Science Institute, has identified what could be a supervolcano on Mars – the first discovery of its kind.
Image: Curiosity trek through 'Pahrump Hills' spotted by Mars Reconnaissance Orbiter
NASA's Curiosity Mars rover can be seen at the "Pahrump Hills" area of Gale Crater in this view from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter. ...
Research says Mars had oxygen-rich atmosphere 4000 million years ago
Differences between Martian meteorites and rocks examined by a NASA rover can be explained if Mars had an oxygen-rich atmosphere 4000 million years ago—well before the rise of atmospheric oxygen on Earth ...
New type of 'space weathering' observed on asteroid Vesta
The surface of the giant asteroid Vesta is weathering in a way that appears to be completely different from any other asteroid yet visited, according to new data recorded by NASA's Dawn spacecraft. This new ...
Curiosity Mars rover finds mineral match
(Phys.org) —Reddish rock powder from the first hole drilled into a Martian mountain by NASA's Curiosity rover has yielded the mission's first confirmation of a mineral mapped from orbit.
Solar wind particles likely source of water locked inside lunar soils
The most likely source of the water locked inside soils on the moon's surface is the constant stream of charged particles from the sun known as the solar wind, a University of Michigan researcher and his colleagues ...
