Another beautiful postcard panorama from Damia Bouic, this time showing a dusky sky during sunset as seen by Curiosity in Gale crater. In this view, the Sun is setting behind the western mountainous rim of the huge crater. Scenes like this are amazingly reminiscent of Earth, even though Mars is a truly alien world in many ways.

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.

This is an interesting rock seen recently by the Curiosity rover on sol 402 (left navigation camera) while making its way toward Mount Sharp in Gale crater. A seat for the weary Martian traveller? :-)

The winds still blow in thin but active Martian atmosphere

For any future astronauts who land on Mars, there is one piece of advice that shouldn’t even need to be said: keep your helmet on! Mars has an atmosphere, like Earth, but it is much thinner than ours (and mostly carbon dioxide), and so is unbreathable by humans. However, evidence has continued to grow that Mars’ atmosphere was once a lot thicker than it is now, early on in the planet’s history. Recent findings from the Curiosity rover have added to that evidence, as well as showing not only how Mars has lost most of the atmosphere that it once had, but also that the atmosphere which remains is still very active.

Has Curiosity found Martian rock varnish?

Scientists studying data from the Curiosity rover have found another interesting puzzle, one which may easily have gone unnoticed were it not for one diligent researcher in particular, it was announced last week at the 44th Annual Lunar and Planetary Science Conference at The Woodlands, Texas.

Curiosity finds odd ‘bubbles’

Having just finished its sampling of the soil at Rocknest, Curiosity is now moving farther north-east into the Glenelg area, and has come across another interesting “curiosity” – small, usually roughly circular ring-like features on some of the surrounding bedrock slabs which look like shallow depressions with a raised rim, kind of like frothy “bubbles” which have popped.
