Satellite


Recommended Posts

I thought this was neat. I don't think it is anything to really worry about, but I thought I'd share it. It is landing over such a large space, the chances of it hitting anything are pretty small. Still kinda scary when you think of 250lbs of steel hitting the earth!

 

Satellite to hit earth

Sheesh....how can they know that it probably won't land on a populated area??? From the tip of Canada to the Southern tip of South America?? Lots of populated areas in that space!

That really seems like a frightening thought! Hope that NASA is correct!

I'm more concerned about what NASA does not tell the public, which historically is the majority of their activities and information, not including a tremendous amount of disinformation.

 

Interesting comment was made that this kind of event happens every year(?) and is nothing to unduly concerned about. If this event is not that unusual, why are they saying something about this one and not the others? And coincidentally its falling at about the same time as a comet that arriving way too close for comfort and nothing is being said about that.

 

Lastest word is that the satellite will not hit the United States. I'll bet all our friendly neighboring countries are happy about that news.

good point! Most of them fall in the oceans don't they? Was this a miscalculation I am wondering?

Don't know about a comet....will be looking into that! thx

Tumbling satellite expected to miss North America

 

By Irene Klotz

 

CAPE CANAVERAL, Florida | Fri Sep 23, 2011 5:24am EDT

 

CAPE CANAVERAL, Florida (Reuters) - A defunct NASA satellite the size of a bus that is expected to fall to Earth on Friday will likely miss North America, NASA said.

 

The agency's 13,000-pound (5,900 kg) Upper Atmosphere Research Satellite, or UARS, has been slowly tumbling from orbit since its mission ended in 2005. It is expected to re-enter Earth's atmosphere and break apart on Friday.

 

Most of the debris will incinerate as it plows through the air, but about 26 pieces, weighing a total of about 1,100 pounds (500 kg), are expected to survive the fall and land somewhere on Earth.

 

Because the science satellite is tumbling, NASA and the U.S. Air Force, which tracks space debris, are not yet able to make an exact prediction about when and where UARS will return to Earth.

 

With 75 percent of the planet covered by water and vast regions of desert and other uninhabited regions, NASA said the odds that a person will be hit by a piece debris from UARS are about 1-in-3,200.

 

The satellite flies over most of the world as it orbits between 57 degrees north and 57 degrees south of the equator. Its altitude on Thursday was about 115 miles above the planet.

 

NASA said on its website on Thursday that re-entry was expected sometime Friday afternoon.

 

"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 to 36 hours."

 

The 35-foot-long, 15-foot diameter (10.6-metres long, 4.5-metres diameter) satellite was launched into orbit aboard a space shuttle in 1991 to study ozone and other chemicals in the planet's atmosphere.

 

Websites offering real-time tracking of UARS include Heavens-Above.com and Space-Track.org.

I think the idea is that it will break up into smaller, burning-out pieces.

 

You never know. Keep an eye out for "falling stars"!
