Curiosity update, sols 1600-1674: The second Bagnold Dunes campaign

Emily Lakdawalla • April 25, 2017

The four-stop dune science campaign offered the engineers some time to continue troubleshooting the drill without any pressure to use it for science. They scooped sand at a site called Ogunquit Beach but couldn't complete the planned sample activity because of new developments in the drill inquiry. The rover has now headed onward toward Vera Rubin Ridge.
