Water Or Not? Fresh Martian Trenches Primarily Due To Carbon Dioxide Freezes, Study Says

by Elizabeth Howell July 11, 2014

Does liquid water currently flow on the surface of Mars? Fresh-looking trenches on the Red Planet have come under a lot of scrutiny, including a 2010 study concluding that 18 dune gullies were primarily formed by carbon dioxide freezing. A new study looking at several more gullies comes to about the same conclusion. Researchers examined […]

Curiosity Captured from Orbit Crossing Landing Ellipse Boundary – Martian Scenery from Above and Below

by Ken Kremer July 10, 2014

NASA has now released a breathtaking high resolution image of the rover Curiosity captured from Mars orbit coincidentally coinciding with her crossing the targeted landing ellipse just days after she marked ‘1 Martian Year’ on the Red Planet in search of the chemical ingredients necessary to support alien microbial life forms. The orbital image was […]

First of all, I completely stole this headline from NASA engineer Bobak Ferdowski (AKA The Mohawk Guy) on Twitter. Second, this is just a great image of the Curiosity rover sitting on Mars, including views of its tracks and where it did a wheelie or two. Plus, where the rover now sits is a very […]

Mars’ Dingo Gap Seen From Orbit and the Ground

by Nancy Atkinson February 12, 2014

Thanks to the Mars Reconnaissance Orbiter and the HiRISE camera, we have an orbital view of Dingo Gap, an opening between two low scarps which is spanned by a single dune. This gap and dune are visible both from the ground and from orbit. The Curiosity Mars rover has now crossed the gap and is […]

Brand New Impact Crater Shows Up on Mars

by Nancy Atkinson February 5, 2014

The great thing about the longevity of the Mars Reconnaissance Orbiter is that we can see changes taking place on the Red Planet, such as this relatively new and rather large impact crater. This image shows a stunning 30-meter-wide crater with a rayed blast zone and far-flung secondary material surrounding. Scientists say the impact and […]
