Melbourne satellite re entry?
Those of us over s/e Victoria tonight were treated to a spectacular show as an object re entered the atmosphere and burned up, around 9:45pm. My guess is satellite, anyone else see it and have an idea?
I took a video but it predictably didn't turn out. Hell of a show though. Looked like the shuttle disaster. |
Reportedly visible from Melbourne in eastern sky heading northwards. Also visible on south coast of NSW too, obviously very high. If multi colored sparks, then it's likely to be satellite debris with the different metals burning different colours.
Otherwise most likely a bolide, or rock shattering on impact with the atmosphere with the greater surface area of the parts allowing more burning, thus appearing brighter than something that might actually reach the ground. |
Also visible from Campbelltown NSW at about the same time. We were heading south on the M5 towards Narellan and saw it heading in a westerly direction. Appeared to be very high. It was indeed spectacular.

Oh no!
The Triffids have arrived. You shouldn't have looked:ooh: EWL |
Was airborne, and one of the most incredible things I have ever seen. Everyone was talking about it over the radio's and the guard police out in force too, good times!
How was that Qantas bloke worried they might encounter debris, classic! |
Looks like it was a meteor.
In todays papers. |
Maybe, but a few minutes sleuthing reveals that space debris number 14037j was tracking to renter the atmosphere overhead Melbourne SSE to NNW at approx 2138 local.
|
OK, thanks.
Normally they give a warning if something is coming down over suburbia or they have done in the past. |
Impressive piece of video here.
Don't see how people can be "shocked" unless we have become a bunch of pansies. Meteor: 'Space junk' lights up Australian skies |
Re lack of warnings. It was likely only a rocket stage or something similar not expected to make ground contact.
|
I wonder if Geoffrey Thomas will give us an expert opinion of the potential aviation safety risk this event may have caused? Perhaps he can recreate some creative scenarios in the Sim and dazzle us with how his expertise would mitigate such an occurrence if it were to happen again?
|
He was on Ch 7 the other day about that Go around because of jet crossing the runway.
I couldn't listen to him ! |
That confirms it for me, at that time I was on approach into OOL and saw a long stream of orange lights to the west. By the time I said to my FO "WTF", checked my TCAS and looked back up it had disappeared. At the time I put it down to the 'mushrooms'.

Good advice, I hope the Air Asia X guys are reading this also ;).
|
From the background comments of whoever shot that video, are you sure it wasn't an outtake from "The Bogan Hunters"?
|
Don't see how people can be "shocked" unless we have become a bunch of pansies. you are clearly some sort of genius that instantly knows all about everything, amazing, I stand in awe.:cool: |
Arnold,
Are you saying most people don't know about meteorites and them entering earths atmosphere ? Especially after the publicity of the Russian ? Not a genius, just done a lot and been exposed to a lot in my life. |
Are you saying most people don't know about meteorites and them entering earths atmosphere ? |
I know, but most things falling out of the sky that make big fireballs are so that is likely to be the most likely thing to think of.

High altitude chemtrail sprayer?:E

Arnold,
It says you are 64. Don't you remember haileys comet ? Or the space junk that re entered and spread metal over Southern aus ? Or seeing shooting stars ? Did yo not see all the pictures and video of the russian meteorite re entry and explosion a few years ago ? It was on all the news and in the papers. All since 1982. |
the battered earth...
spend a few clear nights away from the bright lights and you get plenty to look at.
"Shooting stars" going every which way, big and small. Its the much bigger ones we have to worry about :eek: And satellites too, many of The SYD MEB burn up of space junk was beauty. Falling aeroplane comments notwithstanding Saw goody a few weeks ago... tracked NW to SE over FNQ, made a stripe in the sky, a few bits fell away before it burnt out. Not quite as speccy as MEBs What we really need for CB is a Tunguska Event.!! :ok: |
It just occurred.
It reminded me of an F-111 doing a dump and burn. |
Leonids in 98 or 99 were spectacular. Camped on top of a dune in mungo np and lay in our swags watching fireballs rip across the night sky. Lit up the ground.
And I was airborne and saw the Hyabusa re entry over Woomera a few years back. That was a spacecraft with a story. The NASA DC8 that came over sure had some toys in it. Optically perfect glass cabin windows. If you think how ignorant the general population is about aviation (media too ) there is a similar level of ignorance regarding astronomy. There were media references to this being an asteroid or a comet. That's as bad a clanger as a Boeing Airbus 747. |
Arnold,
Come spend a few nights with us under the stars in the Outback. That'll cause you to raise an eyebrow - and just on 'ordinary' nights. And, of course, the difference between a meteor and a meteorite is only its location. OK? |

Don't you remember haileys comet ?
No, but I do remember Halley's Comet. |
OK, valid point :O
|
And here's a good report as to what it was.
Re-Entry of Soyuz Rocket Stage catches Australian Observers by Surprise - SPACEFLIGHT101 |
It reminded me of an F-111 doing a dump and burn. It was very quiet, no traffic noise, and it seemed to me that I could hear the sound from these, like a high-flying jet aircraft. Would one of our astronomically knowledgeable members be able to comment if this was feasible, or a figment of my imagination. |

Night or day ? Were they travelling horizontal or vertical or across the horizon so to speak. Reason I say is one aircraft makes the noise and flares create the other lights, If of course it was at night. Flares last 30 - 60 seconds and are often fired in 2 - 3's. Wagga is an army training area, especially in 1991. You get some amazing patterns. |
This thread will probably now get longer than Alan's Not Happy, but have you ever thought what might happen if even a tiny bit of incoming debris, natural or man made, impacted your thin aluminium tube at altitude?
Sends shivers up and down your spine, if you stop to think about it. Probably better not to stop to think about it. |
Do a google search on space shuttle debris collision.
Some doozy photos of holes in skin and nice dent, star in windscreen - from a fleck of paint :rolleyes: |
but have you ever thought what might happen if even a tiny bit of incoming debris, natural or man made, impacted your thin aluminium tube at altitude? Most meteoroids (and space junk) burn up by the time they get anywhere near the stratosphere. On the Space Station, however, 430km up they have installed shields to protect against the very real risk of depressurisation due to meteoroid impact. |
CaptG, ask yourself where all the buildings full of holes from meteorite impact are. By the time most meteors/space junk that survives to reach the lower atmosphere (such as where aircraft fly) they are at terminal velocity so a small piece won't be carrying a huge amount of energy. Would a 5mm rock travelling at 200kph penetrate an aircraft skin?
|
Would a 5mm rock travelling at 200kph penetrate an aircraft skin? Who wants to find out? Maybe all jet aircraft need to have mattresses taped to them just in case. :8 They also say there is more chance of being killed by a donkey then killed by being in an aircraft accident. :confused: My luck the flight would go perfectly fine, touch down smoothly then hit the damn donkey on the runway taking me out in the ensuring fireball. :{ |
So the moral of the story is stay away from someone's ass on the runway .... :}
|
Would a 5mm rock travelling at 200kph penetrate an aircraft skin? Would a 5mm rock coming in head on with a closing speed of nearly 1100 km/hr penetrate an aircraft skin? I suspect it would. |
the 5mm rock....
ouch !
Jumbo at 1000 kph meets rock at 200 kph,....I reckon it might put more than just a dent in the Jumbo skin !!! :eek: |

Sightings (at night) were reported from a large parts of western NSW and Victoria. All the objects were on parallel straight tracks, and were later reported to be either a meteorite breaking up or space junk. They travelled at a uniform velocity, and I watched them through an arc of at least 90 deg. I estimated their max. altitude angle at about 60-80 deg. Definitely not flares. As I say, at first I thought they may have been RAAF from Forest Hill. |
