NASA Mars spacecraft reveals a more dynamic red planet
(Phys.org) —NASA's Mars Reconnaissance Orbiter has revealed to scientists slender dark markings—possibly due to salty water - that advance seasonally down slopes surprisingly close to the Martian equator.
Ancient fresh water lake on Mars could have sustained life, Curiosity researchers show
Scientists have found evidence that there was once an ancient lake on Mars that may have been able to support life, in research published today in the journal Science.
Evidence found for granite on Mars
Researchers now have stronger evidence of granite on Mars and a new theory for how the granite – an igneous rock common on Earth—could have formed there, according to a new study. The findings suggest ...
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 ...
Marks on Martian dunes may be tracks of dry-ice sleds
(Phys.org) —NASA research indicates hunks of frozen carbon dioxide—dry ice—may glide down some Martian sand dunes on cushions of gas similar to miniature hovercraft, plowing furrows as they go.
Researchers calculate radiation exposure associated with journey to Mars
On November 26, 2011, the Mars Science Laboratory began a 253-day, 560-million-kilometer journey to deliver the Curiosity rover to the Red Planet. En route, the Southwest Research Institute-led Radiation ...
Terradynamics: Technique could help designers predict how legged robots will move on granular surfaces (w/ video)
Using a combination of theory and experiment, researchers have developed a new approach for understanding and predicting how small legged robots – and potentially also animals – move on and interact with ...
Curiosity rover preparing to drill into first martian rock
(Phys.org)—NASA's Mars rover Curiosity is driving toward a flat rock with pale veins that may hold clues to a wet history on the Red Planet. If the rock meets rover engineers' approval when Curiosity rolls ...
Some Earth bacteria survive and grow at extremely low pressure, may aid Mars research
(Phys.org)—University of Florida researchers have discovered for the first time that some Earth bacteria can live under the same low pressure conditions found on Mars.
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 targets unusual rock enroute to first destination
(Phys.org)—NASA's Mars rover Curiosity has driven up to a football-size rock that will be the first for the rover's arm to examine.
Curiosity rover's laser instrument zaps first martian rock
(Phys.org) -- Today, NASA's Mars rover Curiosity fired its laser for the first time on Mars, using the beam from a science instrument to interrogate a fist-size rock called "Coronation."
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 ...
Organic carbon from Mars, but not biological
(Phys.org) -- Molecules containing large chains of carbon and hydrogen--the building blocks of all life on Earth--have been the targets of missions to Mars from Viking to the present day. While these molecules ...
