Preparations for the first drilling activities continue to go well. The focus of the Sol 170 and 171 plans was to test the ability of arm to press the drill against the surface. Four targets were selected for the "preload" testing, and the arm was left pressed against one of them overnight, to… Read More
I was MAHLI/MARDI uplink lead again today, planning images of potential drill targets. We still need more information before we can start drilling, and there are more tests to be done before the first drilling activity. So it looks like we will be in the same place for several weeks!
Today is the 9th anniversary of Opportunity's landing on Mars. Her twin Mars Exploration Rover, Spirit, sent her last transmission to Earth in 2010, after over 6 years of successful operation on the surface of Mars. Not bad, considering the nominal mission lifetime of the MER rovers was 90 days.… Read More
We have arrived at John Klein, the location selected for the first use of the drill! There are multiple potential drill targets in front of the rover, which must be flat as well as scientifically interesting. The Sol 167 plan includes a MAHLI mosaic of the area that can be reached by the drill,… Read More
The Sol 159 "bump" went well, and we received the images we needed to plan ChemCam, MAHLI, and Mastcam observations in the new location. As MAHLI uplink lead for Sol 160, I was focused on planning close-up images of a bright rock that apparently was broken and freshly exposed by the rover wheel. … Read More
For Sol 159, we planned MAHLI imaging of one more rock outcrop before stowing the arm and driving about 1 meter backward. The goal of this short "bump" is to allow us to use the arm instruments to investigate spherical objects in the rock that some team members have interpreted as… Read More
I was SOWG Chair for Sol 158 planning, and it was an exciting sol. On Sol 156, there was a minor problem with the arm that caused the team to preclude more arm contact science until the anomaly was better understood. Fortunately, good work in the testbed at JPL yesterday verified that the… Read More
I was MAHLI/MARDI uplink lead again for Sol 153 planning, but there were no MAHLI or MARDI observations in the plan, so I focused instead on advance planning for Sol 154. Now that the duration of the daily tactical process has been reduced to 11 hours, part of the science team spends a couple… Read More
USGS Scientist, Colin Dunda, is working to determine what causes gullies on the surface of Mars. He was recently quoted in Science Magazine in reference to his talk given during the December 2012 Meeting of the American Geophysical Union.
A short "bump" toward slightly younger rocks in front of the rover was planned for Sol 151, and no MAHLI observations were included so I had an easy day as PUL. The contact science activities in the current location went well, including the first brushing of the surface. In order to characterize… Read More
