New images of a dry river on Mars.

New images of a dry river bed on Mars.

Reull Vallis, the river-like structure in these images, is believed to have formed when running water flowed in the distant martian past, cutting a steep-sided channel through the Promethei Terra Highlands before running on towards the floor of the vast Hellas basin. This sinuous structure, which stretches for almost [1000 miles] across the Martian landscape, is flanked by numerous tributaries, one of which can be clearly seen cutting in to the main valley towards the upper (north) side.

Volunteers are needed to analyze images from Mars.

Volunteers are needed to analyze images from Mars. From the website:

We need your help to find and mark โ€˜fansโ€™ and โ€˜blotchesโ€™ on the Martian surface. Scientists believe that these features indicate wind direction and speed. By tracking โ€˜fansโ€™ and โ€˜blotchesโ€™ over the course of several Martian years to see how they form, evolve, disappear and reform, we can help planetary scientists better understand Marsโ€™ climate. We also hope to find out if these features form in the same spot each year and also learn how they change.

NASA announced yesterday plans to launch by 2020 a twin rover of Curiosity to Mars.

NASA announced yesterday plans to launch by 2020 a twin rover of Curiosity to Mars.

Though it makes sense to use the same designs again, saving money, I must admit a personal lack of excitement about this announcement. First, I have doubts it will fly because of the federal government’s budget woes. Second, it is kind of a replacement for the much more challenging and exciting missions to Titan and Europa that the Obama administration killed when they slashed the planetary budget last year.

Has Curiosity made a big discovery?

Has Curiosity made a big discovery?

There has been a lot of buzz the past twenty-four hours about the possibility of a major discovery from Curiosity. However, I agree with Jeffrey Kluger at Time. It is dangerous to pay much attention to these wild speculations, as they are often wrong. Stay calm, and wait for some real information. The most likely possibility is that they have found something very intriguing and exciting, but not Earth-shaking.
