Team Prepares to Uplink Commands to Spirit

Image and Caption

Today (Monday, Nov. 16), driving commands are being prepared to instruct Spirit to attempt to drive forward. These are the first driving commands since Spirit became embedded in a Martian sandtrap approximately six months ago. These commands will be transmitted to Spirit at 1 a.m. PST (4 a.m. EST) Tuesday, Nov. 17.

The rover will be instructed to drive straight ahead (north) in two steps. Each step will be a commanded wheel motion of about 2.5 meters (8.2 feet). At the conclusion of the commanded motion, the rover will collect a three-frame Microscopic Imager mosaic of the rover underbelly. Spirit will also collect Pancam images of the middle wheels, pre-drive and post-drive visual odometry (Visodom), Navcam images, and supporting front and rear Hazcam images. The rover will drive with the robotic arm (Instrument Deployment Device) already deployed in the "fishing stow" position, like Opportunity, so it can take Microscopic Imager images without having to stow and un-stow the arm before and after each drive.

The team expects to spend all day Tuesday analyzing the drive results before the next drive attempt, possibly on Wednesday, Nov. 18. It is expected, at least initially, that little actual motion of the rover will be observed.

The attempt to extract Spirit from the Martian sandtrap is expected to take weeks or months, if it is at all possible. The next status update will be issued Tuesday, Nov. 17.
