NASA's Mars Science Laboratory, also known as the Curiosity rover, is in a clean room at the agency's Jet Propulsion Laboratory in Pasadena, Calif. The webcam, affectionately called "Curiosity Cam," provides the video feed, without audio, from a viewing gallery above the clean room floor.

The video will be supplemented periodically by live Web chats featuring Curiosity team members answering questions about the rover. Currently, work in the clean room begins at 8 a.m. PDT Monday through Friday.

Clean room technicians have been busy adding new avionics and instruments to the rover. Beginning Friday, viewers will see technicians carefully add the rover's suspension system and its six wheels. On Monday, Oct. 25, the rover's 7-foot-long robotic arm will be carefully lifted and attached to the front of the rover.

The camera shows a portion of the clean room that is typically active; but the rover, spacecraft components and technicians may move out of view as work shifts to other areas of the room. When activity takes place in other testing facilities around JPL, the clean room may be empty. The camera also may be turned off periodically for maintenance or due to technical issues.

Months of assembly and testing remain before the car-sized rover is ready for launch from Cape Canaveral, Fla. The rover and spacecraft components will ship to NASA's Kennedy Space Center in Florida next spring. The launch will occur between Nov. 25 and Dec. 18, 2011. Curiosity will arrive on Mars in August 2012.

Curiosity is engineered to drive longer distances over rougher terrain than previous rovers with a science payload 10 times the mass of instruments on NASA's Spirit and Opportunity.

The new, large rover will investigate whether the landing region has had environments favorable for supporting microbial life and for preserving evidence about whether life existed on the Red Planet.

Opportunity Past the 15-Mile Mark on Mars
Opportunity crossed the 24-kilometer (15-mile) odometry mark on her way to Endeavour crater.

The rover ended last week with the data backlog which limited activities over the weekend. On Sol 2390 (Oct. 14, 2010), the alpha particle X-ray spectrometer (APXS) was sequenced to collect an atmospheric argon measurement along with light remote sensing.

Not until Sol 2393 (Oct. 17, 2010), were onboard data volumes improved so a drive could be sequenced. On that sol, Opportunity drove over 100 meters (328 feet), crossing the 24-kilometer (15 mile) odometry mark.

The rover drove again on Sol 2395 (Oct. 19, 2010), again reaching over 100 meters (328 miles). Even though the Miniature Thermal Emission Spectrometer (Mini-TES) instrument is still under investigation, the Mini-TES elevation mirror continues to be opened to the environment at regular intervals in the chance of catching a wind-induced cleaning event.

As of Sol 2395 (Oct. 19, 2010), solar array energy production was 627 watt-hours with a slightly elevated atmospheric opacity (Tau) of 0.639 and a solar array dust factor of 0.7015.

Total odometry is 24,192.63 meters (24.19 kilometers, or 15.03 miles).

Spirit Remains Silent at Troy
Spirit remains silent at her location on the west side of Home Plate. No communication has been received from the rover since Sol 2210 (March 22, 2010).

The project is listening for Spirit with the Deep Space Network and Mars Odyssey orbiter for autonomous recovery communication from the low-power fault case and conducting a "Sweep and Beep" strategy to stimulate the rover in the case of a mission clock fault.

Improving solar insolation levels should provide an environment for the rover batteries to recharge, with increasing likelihood of hearing from Spirit in the period ahead.

Total odometry is unchanged at 7,730.50 meters (4.80 miles).
