An amateur astronomer has recorded images of the out-of-control US satellite as it tumbles back to Earth.

UARS could land anywhere between 57 degrees north and 57 degrees south of the equator - most of the populated world.

Nasa says that most of the satellite will break or burn up before reaching Earth.

But scientists have identified 26 separate pieces that could survive the fall through the atmosphere. This debris could rain across an area 400-500km (250-310 miles) wide.

There is so much junk up there, we actually look like we have a ring system like Saturn now, just not as pretty.

Well it will be one satellite clearer soon. :lol:

Nasa said scientists would only be able to make more accurate predictions about where the satellite might land two hours before it enters the Earth's atmosphere.

Maybe we can have a game of satellite bingo? Like Cow [LIFTED] bingo but with satellite parts. :lol:

The most recent update from NASA.com

Quote:
As of 9:30 p.m. EDT Sept. 22, 2011, the orbit of UARS was 110 mi by 115 mi (175 km by 185 km). Re-entry is possible sometime during the afternoon or early evening of Sept. 23, Eastern Daylight Time. The satellite will not be passing over North America during that time period. It is still too early to predict the time and location of re-entry with any more certainty, but predictions will become more refined in the next 24 hours.


Nice, so North America (who frakin own it) is probably in the clear.

Edit: Apparently when the UARS was designed there wasn't the same human casualty risk assessment as there is today. They now try to limit it to a 1 in 10,000 chance. The current risk assessment puts the UARS human casualty risk as 1 in 3200.

I bet on horses with bigger odds than that. :lol:

Edit, edit: Currenty tracked orbit. Most likely scenario is that it will hit the Atlantic but the orbit is obviously evolving.

The NASA twitter is saying that re-entry will now be later tonight or early tomorrow EDT.

Theres' speculation of some of it now hitting the US and the African Space Surveillance Ops Centre has issued warnings to people in Africa not to touch any debris.

Anybody see anything when it passed over London? Doubtful I guess.

I installed that earlier. Unfortunately, I think a zillion other people did too because it says the server is off-line :(

And deprive people of the chance of acquiring super powers of the radioactive remains? :(

It's supposed to be down, no NORAD data anymore. Suggestions of it in Alberta, Canada region, unconfirmed reports of debris trail in the sky NW of Lethbridge.

NASA’s decommissioned Upper Atmosphere Research Satellite fell back to Earth between 11:23 p.m. EDT Friday, Sept. 23 and 1:09 a.m. EDT Sept. 24. The satellite was passing eastward over Canada and Africa as well as vast portions of the Pacific, Atlantic and Indian oceans during that period. The precise re-entry time and location are not yet known with certainty.


Pants, doesn't look like anyone has seen anything. Anti-frickin-climax.

The Joint Space Operations Center at Vandenberg Air Force Base in California said the satellite penetrated the atmosphere over the Pacific Ocean. The precise re-entry time and location are not yet known with certainty.


So, the only for certain at the moment is that it penetrated the atmosphere of the 3rd planet from the sun in our solar system.

As soon as we see bits as listed for sale on eBay then we will have a better idea of where it landed. :lol:
