Curiosity Mars rover beams back ‘artistic’ postcard view of Gale Crater

26 November 2021 Astronomy Now

Pausing on the slopes of Mount Sharp, NASA’s Curiosity Mars rover set back two black-and-white panoramas that were colourised to provide an “artistic” view looking back along its recent path with the rim of Gale Crater rising in the distance.

Mars rover data indicates ancient megafloods across Gale Crater

24 November 2020 Astronomy Now

Stratigraphy in Gale Crater on Mars indicates the effects of megafloods in the distant past, most likely caused by the heat released in a major impact.

Engineers have started testing a new way to use the Curiosity rover’s drill to bore into Martian rocks after a motor in the device stalled late last year, but ground teams are still months away from the first chance to resume drilling operations.

Internal debris may be causing problem with Mars rover’s drill

Engineers believe a piece of foreign object debris may be intermittently stalling a motor needed to place the Curiosity Mars rover’s drill bit onto rocks, and the robot’s ground team is assessing the source of the potential contamination.

Mars rover’s drill out of action

18 December 2016 Stephen Clark

The rock-coring drill fixed to the end of the Curiosity rover’s robot arm has suspended operations to allow engineers on the ground to diagnose, and officials hope correct, a problem traced to the mechanism that pushes the drill bit onto rocks to collect powder samples.

Martian valleys could have been carved by surprisingly little water

5 November 2015 Astronomy Now

Vast valley networks on Mars have suggested that water may have flowed there for millions of years. Now a study at Brown University suggests the valleys could have been carved by much less water in as little as a few hundred to 10,000 years. The findings are consistent with the idea that early Mars may have been cold and icy, with surface water flowing sporadically in response to short-term climate changes.
