Eerie 'fireball' seen over Australia was actually a Russian rocket in disguise

A Russian rocket body fell back to Earth near southern Australia on Monday night (Aug. 7), putting on quite a show for observers in the region.

The crashing rocket generated a "fireball and sonic boom that rattled homes across Victoria," 7 News Australia said via X (formerly Twitter) on Tuesday (Aug. 8), referring to the southern state whose capital, Melbourne, is Australia's second-largest city.

The hunk of space junk hadn't been up there long; it was the third stage of a Soyuz rocket that had launched a Glonass navigation satellite earlier that same day, according to astrophysicist and satellite tracker Jonathan McDowell.

That mission lifted off at 9:20 a.m. EDT (1320 GMT) on Monday from Plesetsk Cosmodrome in northwestern Russian and zoomed toward space on a southeasterly track.

The Soyuz's third stage ended up reentering Earth's atmosphere southeast of Tasmania, over the open ocean, around 10 a.m. EDT (1400 GMT; midnight Melbourne time), McDowell said.

The crashing rocket body was not the Soyuz's uppermost stage, known as Fregat, by the way; that vehicle continued carrying the Glonass satellite toward its intended orbit. (We would probably consider the fallen body the Soyuz's second stage, but Russian space officials count the rocket's strap-on boosters as its first stage, McDowell noted in another social media post.)

The Soyuz stage hit the atmosphere going several kilometers per second, said Michael Brown, an associate professor in the School of Physics and Astronomy at Monash University in Melbourne.

"Space junk reentries are sometimes confused with meteors, which are also spectacular but are usually far shorter events, as they slam into the atmosphere at a much faster speed," Brown said in an emailed statement about Monday's event.

"It is possible that small pieces of the rocket crashed to earth or into the sea, but it's rare for space junk to damage property," he added.
