Curiosity update, sols 814-863: Pahrump Hills Walkabout, part 2

Posted by Emily Lakdawalla on 2015/01/21 07:24 CST | 5 comments

Curiosity has spent the last two months completing a second circuit of the Pahrump Hills field site, gathering APXS and MAHLI data. The work has been hampered by the loss of the ChemCam focusing laser, but the team is developing a workaround. Over the holidays, the rover downlinked many Gigabits of image data. The rover is now preparing for a drilling campaign.

Curiosity results from AGU: Methane is there, and it's variable

Posted by Emily Lakdawalla on 2014/12/30 04:21 CST | 6 comments

At the American Geophysical Union meeting, the Curiosity mission announced that an instrument had finally definitively detected methane in Mars' atmosphere. It exists at a low background level, but there was a spike to about ten times that, which lasted for a couple of months before disappearing. What that means is unclear.

Curiosity update, sols 764-781: Work complete at Confidence Hills; puzzling arm issues

Posted by Emily Lakdawalla on 2014/10/17 12:53 CDT | 7 comments

Curiosity spent a total of four weeks at Confidence Hills, feeding samples to SAM and CheMin several times. On two weekends during this period, the rover's activities were interrupted by faults with the robotic arm. Curiosity drove away from Confidence Hills on sol 780, and is ready to observe comet Siding Spring over the weekend.

Curiosity update, sols 748-763: Driving and Drilling at Pahrump Hills

Posted by Emily Lakdawalla on 2014/09/29 05:57 CDT | 10 comments

The biggest news on Curiosity of late is that the rover has drilled her fourth full drill hole on Mars! Drilling happened at a site called "Confidence Hills" on sol 759. But before she did that, she took a long series of amazing photos of rock formations at Jubilee Pass, Panamint Butte, and Upheaval Dome.

Curiosity update, sols 727-747: Beginning the "Mission to Mount Sharp"

Posted by Emily Lakdawalla on 2014/09/12 07:08 CDT | 3 comments

A lot has happened behind the scenes on the Curiosity mission in the last few weeks. The mission received a pretty negative review from a panel convened to assess the relative quality of seven different proposed extended planetary science missions. Then, just a week later, the mission announced big news: they have arrived at Mount Sharp.
