A 20-year-old military weather satellite apparently exploded in orbit Feb. 3 following what the U.S. Air Force described as a sudden temperature spike, SpaceNews reports.
The "catastrophic event" produced 43 pieces of space debris, according to Air Force Space Command, which disclosed the loss of the satellite Feb. 27 in response to questions from SpaceNews.

The satellite, Defense Meteorological Satellite Program Flight 13, was the oldest continuously operational satellite in the DMSP weather constellation.

Launched in 1995, DMSP-F13 provided thousands of hours of weather imagery to Air Force and Navy forecasters before transitioning to a backup role in 2006. The Air Force said its sudden loss would have minimal impact.

...Air Force Space Command said DMSP-F13's power subsystem experienced "a sudden spike in temperature" followed by "an unrecoverable loss of attitude control." As DMSP operators were deciding to "render the vehicle safe" the Joint Space Operations Center at Vandenberg Air Force Base, California, identified a debris field near the satellite.

The Air Force said it is continuing to track the debris and will issue conjunction warnings if necessary.
