This is interesting, a recent HiRISE photo from the Mars Reconnaissance Orbiter spacecraft showing an oval pit or crater with an opening in the bottom (cropped here from one of the larger images) near Galaxias Chaos on Mars. The opening is also oval, and you can see some sand dunes on the bottom. How did it form? More images are available here.

As it continues to make its way to Mount Sharp, the Curiosity rover has been sending back to Earth some amazing images of the Martian surface. This latest “postcard” panoramic image by Damia Bouic is a montage of some of these latest photos, from sol 409. Part of the rim of Gale crater can be seen in the distance. Larger versions of the image (black & white and colour) can be seen here (French website). Thanks again to Damia for the use of her images, which beautifully capture the Martian scenery; the next best thing to actually being there! The rest of his Curiosity images can be seen here.

This Mars rock has teeth

As the Curiosity rover currently inspects a rock outcrop called Cooperstown, this rock seems to be baring its teeth. Some interesting pointed protrusions can be seen near the middle and lower right of the image. Below is a closeup of one of these teeth-like protrusions. Fossilized Martian shark teeth? No, probably not, but they are an intriguing feature for sure.

Will Curiosity find new clues to ancient Martian habitability, or perhaps even life, at Hematite Ridge?

As the Curiosity rover gets ever closer to its major destination of Mount Sharp, there is an interesting feature there which has become a priority target, one which may help scientists to further study the past habitability of this area, or even provide possible clues to life itself.

Mars is a planetary destination that so far has only been reached by a handful of countries including the United States, the former Soviet Union and some countries in Europe. But soon, another nation may finally take its place on that list as well – India. Having already successfully sent its first unmanned probe, Chandrayaan 1, to the Moon a few years ago, India is now setting its sights on a much more distant goal, Mars.
