DMSP satellite’s break-up linked to battery failure


DMSP satellite’s break-up linked to battery failure Investigators have traced the cause of an in-space disintegration of a U.S. Air Force weather satellite in February to a battery fault and identified six other spacecraft in orbit prone to the same failure. Engineers originally suspected the polar-orbiting satellite’s power system was to blame for the Feb. 3 explosion, which littered low Earth orbit with 147 objects ranging from the size of a baseball to the size of a basketball, according to an Air Force press release. A report from engineers investigating the break-up of the Defense Meteorological Satellite Program Flight 13, or DMSP F13, spacecraft revealed the probable cause of the failure was a compromised wiring harness inside a battery charger aboard the satellite.   More
