Curiosity Update, Sols 2313-2387: Two New Drill Holes Despite Memory Problems

Emily Lakdawalla • April 25, 2019

The Curiosity team is touring Glen Torridon, the Valley of Clay, south of Vera Rubin Ridge, happily photographing everything and zapping rocks. It’s clearly a delight for the team to be in a place they’ve been hoping to reach for 7 years.

Curiosity Update, Sols 2257-2312: Drilling at Rock Hall and Arrival at the Valley of Clay

Emily Lakdawalla • February 06, 2019

Curiosity completed work at Vera Rubin Ridge with an easy drilling activity at Rock Hall. Now it has finally driven on to mineral-rick rocks that were seen from orbit, long before Curiosity arrived. The team plans a lengthy traverse of the clay-bearing unit.

Curiosity Update, Sols 2163-2256: Hard Times Atop Vera Rubin Ridge

Emily Lakdawalla • December 11, 2018

Just after a failed drill attempt at Inverness, Curiosity suffered a serious computer problem. The mission has now recovered by switching computers, and has successfully drilled at Highfield. One last drill site in "red Jura" rocks is planned before leaving Vera Rubin ridge behind.

Curiosity update, sols 2093-2162: Three tries to successful drill atop Vera Rubin Ridge

Emily Lakdawalla • September 06, 2018

Heedless of the (now-dissipating) dust storm, Curiosity has achieved its first successful drill into rocks that form the Vera Rubin ridge, and is hopefully on the way to a second. It took three attempts for Curiosity to find a soft enough spot, with Voyageurs and Ailsa Craig being too tough, but Stoer proved obligingly soft on sol 2136.

Emily Lakdawalla • January 06, 2018

Curiosity is climbing across the top of Vera Rubin Ridge, spying varicolored rocks. It's getting closer to being ready to drill again, and has performed a wet chemistry experiment for the first time.

Curiosity update, sols 1726-1813: Surveying Vera Rubin Ridge from below

Emily Lakdawalla • September 13, 2017

Curiosity had a productive three months driving along the front of Vera Rubin Ridge, gathering photos and data with its arm instruments, finally driving up on to the ridge on sol 1809.

Curiosity's balky drill: The problem and solutions

Emily Lakdawalla • September 06, 2017

Since December 1, 2016, Curiosity has been unable to drill into rocks because of a serious problem with one of the drill's motors. Emily Lakdawalla thoroughly explains the issues and the path forward for Curiosity.
