NASA: Spirit still stuck in martian sand
Pasadena, Calif. (UPI) Jul 9, 2009 U.S. space agency engineers said they used backward motion during the second evaluation of maneuvers that might free a stuck Mars rover. NASA's Mars rover Spirit became trapped in April in loose martian sand. Jet Propulsion Laboratory engineers in California have been using a test rover placed in a specially constructed sandbox to simulate how to best extract Spirit. During the first evaluation, conducted Monday, the engineers experimented with simply moving the rover forward. That proved unsuccessful when the test unit moved only slightly forward before sliding sideways down a slope. The second evaluation was conducted Wednesday, but results were not announced. "Weeks of further testing and analysis are expected before engineers identify the best moves to command Spirit to perform," NASA said in a statement. "Meanwhile, Spirit is using its science instruments to examine the environment surrounding (it) on Mars." Share This Article With Planet Earth

NASA works on Spirit's extractionPasadena, Calif. (UPI) Jul 7, 2009 The U.S. space agency says it's using a test rover placed in a sandbox to simulate how best to get the rover, Spirit, extracted from loose Martian soil. Engineers at NASA's Jet Propulsion Laboratory said they are using a special soil that simulates Spirit's predicament on Mars to assess possible maneuvers for getting Spirit onto firmer ground. They began Monday with the simplest ... read more |
