Age of warning satellite causes concernWashington (UPI) Mar 9, 2012 A U.S. satellite giving the only advance warning of incoming high-energy solar particles is getting old and is possibly on its last legs, researchers say. But a replacement for NASA's Advanced Composition Explorer, or ACE, satellite is at least two years away, they said. ACE provides the only advance notice of incoming high-energy particles from the sun which can wreak havoc on indispensable radio, GPS and satellite communications, researchers said. Launched in 1997, ACE gives th ... read more |
