DirecTV is racing to move its Spaceway-1 satellite out of the geostationary arc after the 15-year-old satellite suffered a crippling battery malfunction that the company fears could cause it to explode. From a report: DirecTV told the U.S. Federal Communications Commission that it does not have time to deplete the remaining fuel on Spaceway-1 before disposing of it by boosting it 300 kilometers above the geostationary arc, a region home to most of the world’s large communications satellites. Spaceway-1 is a Boeing-built High Power 702 model satellite that was designed to last 12 years. Launched in 2005 on a Sea Launch Zenit 3SL rocket, the 6,080-kilogram satellite originally provided high-definition television direct broadcasting services from its orbital slot at 102.8 degrees west longitude. More recently, Spaceway-1 was being used to backup Ka-band capacity over Alaska. In December, an unexplained anomaly caused “significant and irreversible thermal damage” to Spaceway-1’s batteries, DirecTV said in a filing dated Jan. 19. Boeing, the filing says, concluded that the batteries are at high risk of bursting if recharged, since the damaged cells can’t be isolated.
