World Geography: Mars

NASA’a Pathfiner touched down on the surface of Mars on July 4, 1997. To cushion its landing, Pathfinder was surrounded by air bags. Shortly after landing it opened up to allow Sojourner, a small six-wheeled vehicle, to begin exploring the surface of Mars around the landing site. This site was chosen because it contains a wide variety of rocks that are believed to date back to Mar’s early history. Once the lander’s camera has photographed the area around the rover, scientists at the Jet Propulsion Labratory (JPL) in Pasadena, California, will decide where they want Sojourner to go. The rover will be guided by a technician at the JPL. Since it takes 11 minutes for a radio signal to travel from Pasadena to Mars, if the driver saw Sojourner heading for a cliff and told the rover to “turn”, it would go over the cliff before the signal arrived on Mars.
