[00:00:10] I'm the rover driver team lead for Spirit and Opportunity and I'm here today to fill you in on what our intrepid rovers have been up to lately. [00:00:17] As of today, both rovers have been operating on Mars for more than 1,600 Martian days. Both rovers continue to operate and to do science from the Martian surface. [00:00:27] Opportunity is moving up in the world; She's back up on higher ground after a safe exit from Victoria Crater. [00:00:32] Opportunity spent nearly a full Earth year exploring the inside of Victoria crater, in the process returning spectacular and unprecedented views into the Martian past. [00:00:42] But after seeing a one time spike on Opportunity's left-front wheel, the team decided it would be safest to wrap-up science operation inside the crater [00:00:50] and return to flat ground on the outside, as soon as possible. [00:00:54] In order to accomplish this important goal, the team worked on "Mars time," setting our Earthbound work schedules to match the slightly longer Martian day. [00:01:02] Even though this meant working well past midnight, it was the way we could make the most progress in the shortest time. [00:01:08] Despite the rapid pace set for exiting the crater, Opportunity found time for an activity most of us associate with lazy Sundays -- watching the clouds go by. [00:01:17] Meanwhile, on the other side of Mars, at Gusev Crater, Spirit is riding out a very tough winter. [00:01:22] She's waiting for power levels to rise high enough that she can resume exploring actively. [00:01:27] In order to survive the winter she had to park on a north-facing slope at a very steep tilt to aim her solar panels more directly at the sun. [00:01:34] Now this image shows the extreme northerly tilt that Spirit had to achieve in order to safely survive this winter. [00:01:40] The team is keeping a very careful eye on the weather near Spirit's location, watching for any rise in atmospheric dust that might foretell a corresponding drop in her power levels. [00:01:48] But so far, we haven't seen anything to worry about. [00:01:52] Spirit made time recently to perform the interplanetary equivalent of synchronizing your watches. [00:01:56] She sent an electronic beep tone back to Earth at a specified time, and we watched for the arrival time of that signal in order to set our Earth clocks to match hers. [00:02:05] I'm Scott Maxwell, and this has been your rover report. [00:02:08] NASA's Jet Propulsion Laboratory, California Institute of Technology [00:02:12]
