The NASA Mars rover Curiosity is still out there, day in and day out, doing Science for us all! The latest discovery to come from this hard working and vastly in-extra-innings ‘bot centers around the 3 mile tall Mount Sharp, located in Gale crater on the Martian surface. Using an improvised gravimeter, rigged from the existing accelerometers on board the vehicle, they have found strong evidence that the towering mountain was created through a long process of stacking wind blown material as it was driven into the crater. This is the far less likely result, geologically speaking, but thanks to the new ability to measure the surprisingly low density of the material comprising Mount Sharp, the stacking model looks more likely than one of erosion over time.
The best takeaway here, is of course that it’ll still make a great ski slope in a few years, but may need a little firming up in places. Also, that Curiosity is still working hard, along with the Earth-side engineers who continue to wring valuable Science from our future spare home planet, every hour of the day!
