Here is a link to the press release we're talking about today:
NASA's Curiosity rover certainly has uncovered unusual features of Mars. Recently the rover was used by scientists to take a closer look at grid-like patterns of shallow ridges on slabs of rock. It seems that these ridges may have originated as cracks in drying mud, similar to features seen in drying lake beds on Earth. If it turns out that these are indeed mud cracks, they show that the generally wet conditions long ago at Curiosity’s site occasionally dried out.
Join Tony Darnell and Carol Christian on February 23, 2017 at 3PM Eastern time, as they discuss with Ashwin Vasavada (JPL), Nathan Stein (Caltech) and Rachel Kronyak (U. Tennesee) as they discuss how they found these unusual Martian features and proposed how they originated.
