One or both of the ramps will be unfurled, and then scientists will decide whether the rover will use either the forward or backward ramp for its descent. The airbags behind the rover were at this time blocking the ramp from being safely unfurled. A number of image processing artifacts are seen in this picture. Most apparent are seams between sub-frames offsetting portions of the rover's wheels and solar panel, color fringes that result from viewing the rover from the two separated eyes of the camera, and blocky fringes near edges and smooth areas that are created by data compression. Barnacle Bill, Yogi, Scooby Doo, and Lamb have been investigated by the Sojourner rover and its Alpha Proton X-Ray Spectrometer.
Couch is a large rock on the horizon.
The names are used by the Pathfinder team to help identify and keep track of the many rocks at the landing site. Best seen with Netscape Navigator and MS Internet Explorer.
