The agency posted on its official Twitter site that the spacecraft crashed through the atmosphere early Saturday morning. A location was not immediately known.

Most of it was believed to have burned up.

Sky9 was on the lookout and captured the Upper Atmospheric Research Satellite (UARS) on camera Friday evening as it streamed across the Southland sky.

The satellite was NASA’s biggest spacecraft to tumble out of orbit, uncontrolled, in 32 years.

UARS was launched aboard space shuttle Discovery in 1991. NASA decommissioned the satellite in 2005, after moving it into a lower orbit that cut its life short by two decades.

Bits of space junk re-enter the atmosphere virtually.
