"We've planned investigations that will not only tell us about modern dune activity on Mars but will also help us interpret the composition of sandstone layers made from dunes that turned into rock long ago," said campaign co-head Bethany Ehlmann of the California Institute of Technology and NASA's Jet Propulsion Laboratory. What's new with you? /Ruwj5jhM1V- is monitoring the area's wind speed and direction, and will collect samples for analysis. I'm on a road trip to Mars' Bagnold Dunes. Observations from orbit indicate the dunes are moving about one metre per year. One of the dunes is as large as a two-storey building and as broad as a football field, according to NASA. The so-called Bagnold Dunes are on the northwestern flank of Mount Sharp, which Curiosity reached last year. "The ripples on them are much larger than ripples on top of dunes on Earth, and we don't know why." "These dunes have a different texture from dunes on Earth," said Nathan Bridges of Johns Hopkins University - who co-heads Curiosity's "dune campaign" - in a statement. It is hoped that the observations will answer questions about how dunes and wind interact in a low-gravity, low-pressure environment.
The rover's latest effort marks the first time active sand dunes have been explored on another planet.

Pictures of the dunes, taken by the rover's black-and-white navigational cameras, were posted online by NASA late Thursday.
The Mars rover Curiosity has moved in for a closer look at giant sand dunes on the Red Planet - sending back fresh images of their dark, rippled surface along with a few partial selfies.
