The Pathfinder lander and Sojourner rover concluded their 14th successful day of operations on the surface of Mars today, JPL engineers reported.

Highlights of the scientific data returned overnight include a series of images that show Sojourner approaching the white rock Scooby Doo and deploying the rover's X-ray spectrometer instrument to study the rock's surface. Imaging data from the lander's camera also included a high-resolution view of the northernmost of the Twin Peaks seen on the horizon from the landing site.

Pathfinder engineers said all subsystems on both the lander and rover performed flawlessly and that no resets of the lander's computer were detected.
