Software enables satellite self-service in space NASA NEWS RELEASE Posted: October 8, 2004 NASA scientists recently radioed artificial intelligence (AI) software su ccessfully to a satellite and tested the software's ability to find and analyze errors in the spacecraft's systems. The AI software, Livingstone Version 2 (LV2), automatically detects and d iagnoses simulated failures in the NASA Earth Observing One (E0-1) satel lite's instruments and systems. E0-1, launched in November 2000, is a fl ying test bed for new technologies and techniques intended to boost safe ty, and to reduce costs and development times. "This is the kind of technique and technology NASA needs to support explo ration of the Earth, moon, Mars and beyond in the 21st century," said Gh assem Asrar, deputy associate administrator for NASA's Science Mission D irectorate. "This software grants us the ability to troubleshoot the rob otic systems required to handle increasingly complex tasks of exploratio n, while they are millions of miles and perhaps light years away from Ea rth," he said. "Livingstone gives us a chance to recover from errors, protect our invest ments in space and continue to achieve our mission goals," said Sandra H ayden, the Livingstone E0-1 experiment principal investigator. She is a scientist at NASA Ames Research Center, located in California's Silicon Valley. "It is critical to ensure spacecraft systems behave as designers intended, and to accurately diagnose potential problems," Hayden said. Tests of the LV2 computer program are taking place while another software application controls E0-1. NASA's Goddard Space Flight Center (GSFC), Greenbelt, Md, manages E0-1 operations. LV2 is monitoring the ASE software, as it autonomously runs the satellite 's imaging systems. If the EO-1 does not respond properly to ASE control , then LV2 detects the error, makes a diagnosis and radios its analysis to mission control at Goddard. LV2 will decide the best way future missi ons with subsystem failures can continue and still achieve goals. LV2 works by comparing a computerized model of how the spacecraft's syste ms and software should perform against actual performance. If the spacec raft's behavior differs from the model, then the LV2 'reasoner' looks fo r the root cause of this difference and gives flight controllers several suggestions of what might have gone wrong. Scientists designed the LV2 software 'reasoner' independent of the comput erized model of the spacecraft systems. To use it on another satellite, an engineer can apply much of the system model created for a previous sp acecraft. All LV2 E0-1 experiments have been s uccessful, with the rest scheduled over the next few weeks. Livingstone's developers feel the software diagnosis tool could be used t o find errors in robots or rovers exploring Mars or other planetary bodi es. Engineers state that when human beings venture deeper into space, cr ews will need automatic tools like Livingstone software to identify spac ecraft problems early and make prompt repairs. "In a future, long-duration human mission to Mars, frequent and extensive spacecraft maintenance operations or overhauls will not be an option," explained Serdar Uckun, technical lead for integrated systems health man agement at NASA Ames. Scientists predict Livingstone software and its descendents will find wid espread use at NASA, in the aerospace industry and in other enterprises as equipment and software intricacy increases.
