3.5 Ton Satellite to Crash Back to Earth
DeadBugs writes "CNN is reporting that the NASA Extreme Ultraviolet Explorer could crash back to earth in a matter of days. It's estimated that up to 9 large pieces (4-100 lbs.) of the Satellite could survive re-entry. Unlike the Compton Gamma Ray Observatory that was guided in, this Satellite will be uncontrolled. The EUVE has only been up there since 1992.... I wonder when this sort of thing will start to be a more common event."
I wonder if they can predict what the "catchment area" of the debris is going to be.. -keshto
Hey, Nothing beats flying debris hitting your back yard on a saturday afternoon.... Maybe you can sell the wreckage on e-bay and make a fortune.. ;-)
Did NASA think they had to get hip to the 90's X-games obsession or something? Take ultraviolet measurements WHILE SNOWBOARDING!
Where is it and what do we win if it hits.
...that some joker will have a piece of it up for auction on e-bay before the derbis has cooled.

This is likely to become far more common. More and more old satellites are being shut down, and people tend to spend their satellite funding on running and using the satellite, not bringing it down safely. Maybe i should start selling insurance....

This is amusing in that car-wreck sort of way. Who wants to bet that when this crashes on Mrs. Tingle's Rose Garden in Bummsville, Idaho and there's a lot of media attention, that the government is gonna spend lots of money to go up there and give these things emergency navigation systems so that they can easily fall on unsuspecting sea mammals instead of J. Random Human?

I hope it lands on my house. I could sell the movie rights for it. Then we can have a whole series of movies about huge satellites returning threatening all life as we know it.

Hell, I don't even think insurance covers this sort of thing.

I can tell you right now that if one of those pieces falls in my back yard, I'll rebuild it and have a webserver running on it with the new Lego set I just bought by the next day...
Falling rocks from the sky? Is this the Art Bell show or something? I wonder if we could target the ./ effect towards Art's web site so he could experience a falling web server.
Good to see that she is married, if she was doing that with anyone other than her husband then it would just be sinfull. Nice to see people still have morals today
This is definitely *not* an "act of God." So I wonder if my insurance policy will cover if it comes down on my house, car, wife, dog (just kidding - I don't have a dog)
with the number of objects we've put into orbit around our planet at an all time high and increasing constantly this will become more and more common. logic dictates that ultimately these things will make land in someone's yard (living room, white house, etc.).
the real problem here is what to do about it...
i propose using defunct home Internet appliances as projectiles. it would be extremely inexpensive and, when fired from a railgun at speeds in excess of 30,000ft/sec, these little beauties could easily eliminate a chunk of space debris weighing 100 or more lbs.
I'd love to have a beowulf cluster of burning satellite pieces!!! ;-)

Funny stuff.
Or do they mean no FUNCTIONAL onboard steering system? I don't know of many satellites that don't include manuvering thrusters. Orbits decay naturally and require slight adjustments over time.
Of course, it WAS described as defunct, so I suppose I can give them some leeway on that.

Play with my webcams and lights here
OK... so these things have a fairly limited and predictable life span. And there's thousands of good sized objects up there that WILL fall(what goes up must come down, unless you put it waaaay up there)
:)
There REALLY should be a way to contoll the destruction better, instead of just letting it drop. Granted making it drop might be better, but this thing will still have some pretty good chunks hitting the ground. Why not design them to break up or be broken up more thoroughly. Somewhat similar to what an Indy Car does when hitting a wall.
Putting explosives and the like would be somewhat risky, and designing weaknesses into the stucture might weaken it. But, having a 200lb chunk nail my house at mach 6 wouldn't be the best either
it was probably not geosynchronous...
Could you design a sattelite in such a way that it could be destroyed remotely, ie. blown into small chunks that pose no danger to other spacecraft (are "blasted" towards Earth and therefore certain disintegration), while maintaining stability during launch/operation and not adding too much to the total weight?
Devil's advocate:
Who'd enforce it? Corporations won't pay extra for a very unlikely liability problem (until such a time that we're lobbing dozens of big things into space daily)
What circumstances (other than system failure) would cause you to push the button - and if it had failed, who's to say it's pointed the right way and you won't shoot your comsat into the ISS?

Actually, debris entering the atmosphere (man-made and not) is a common occurrence. Happens everyday on some scale. It isn't just everyday a 3.5 ton one comes down :)
I believe US Space Command/NASA/NORAD spends a ton of time tracking objects in close orbit, even very small ones the size of your finger.
After all, anything going 17500 miles per hour hitting something like the space shuttle or Hubble or any other satellite (GPS, communications, spy/defense) wouldn't be pretty.
Someone who worked for NASA at MSFC told me that they have actually had astronauts on the space shuttle change the shuttle's orbit slightly in order to avoid certain large pieces of debris.

Perhaps they should keep a supply of fuel that is not to be used up on any circumstances... other than when the satellite is crashing of course.

I am not an engineer but.....
I'll understand it if nasa puts up a 500 lb satalite, or even a 1 ton satalite that has such a short lifespan. But come on. at 3.5 tons they couldn't have fitted it with at least enough energy collecting equipment to keep the thing in orbit?
Sure the equipment was dated, and some it probably worn out, but whats the real harm of leaving it up there and using it for parts or salvage for future missons?
Is the feasibility of making/expanding/fixing a space station out of these defunct satalites so remote?
Granted using parts of old satalites to fix or augment current satalites or stations would require them to be designed as such from the beginning. Still I would think the idea isn't origonal, or too far fetched to acheive.
You are only young once, but you can stay immature indefinitely.
Will Taco Bell put another target up and offer free tacos if it hits?
If they don't will CmdrTaco do it? Come on Malda I only live in Grand Rapids! Give us free tacos!
Think about this: the US military sends up approx. 10-20 satellites a year into space, and have you ever heard of them telling us when one is coming down? You can bet they try their hardest to keep any information from us, even if it threatens the public safety.
:)
I'm sure they probably count on the odds that they crash over water, or some unpopulated area, and not notify anyone beforehand. Or if it does get hit something, they'll attribute it to some plane part falling off...
I know there's not a whole lot we can do about it ... but couldn't the media have given us a bit more warning. It's less than 30 hours from the CNN article to the earliest estimated reentry time.
NASA's original press release was on the 16th Feb.
Even that is a bit worrying. Did NASA only discover 11 days ago that their 3.5 tonne satellite was going to crash? It's not like they behave erratically, is it?
For being the #1 space program, we sure as hell can't keep a satellite up there for long.

This sounds like a great opportunity to run another test of the National Missile Defense system.
Better yet, let's turn it into an X-Game type competition between the BMDO and National Skeet Shooting Association to see who can hit the first/most chunk(s).
wouldn't this be a cheap way to test the new system, at least it would give NASA an excuse it hadn't used before.
"It blew the F$#@! up, only this time we know why!"
I get it. It's a joke about Windows. The punchline is that Windows crashes all of the time, so if NASA used Windows on the satellites, they would crash all of the time.

There is no longer anything that can be done with computers that is nontrivial and clearly legal. -- Paul Phillips
i don't really know how all of the legal angles work when it comes to NASA's liability - but here's my theroy:
lets assume this satalite hits a house - the cost of a lawsuit/repairs/etc are FAR less than building in some sort of self destruction devices, and paying people to maintain such a thing. i think the NASA people are just taking their chances hoping it lands in the ocean or in an unpopulated area, and if not - they're prepared to pay whatever the cost may be.

>Self-destruct mechanisms as a design feature for all sattelites...
/. in the past over deorbiting a still operational satellite. Well, WHY DO YOU THINK THEY DO IT? Purely to avoid this situation.
As afidel wrote above (I'd mod him up if I had any points now), you don't want to do this to a defunct satellite.
As you point out, it would have to pose no danger to other spacecraft. Well, the only practical way to do that is to ditch it in a controlled fashion. Any explosion involves a release of energy in pretty much all directions. Although some shaping of the charge can control the blast, you still blast some pieces in every direction. Each piece that does not hit the atmosphere enters its own orbit - risking collision with some other satellite.
The proper solution, employed by almost all responsible satellite designers, is to allow enough extra fuel to deorbit the satellite. Of course, this depends on having CONTROL of the satellite. To guarantee this requires more redundancy - and more weight and fuel and complexity, etc. At the tens or hundreds of thousands of dollars a pound for launch costs, the designers usually opt for mission-suitable redundancy, and hope (and pray) that all the systems don't fail before they DO deorbit. And if they do start failing unusually fast, they'll deorbit early to avoid this kind of fiasco.

And found an article on the satellite crashing. It doesn't go into much detail but covers much of what the CNN story is missing. I thought it might be interesting to some. It can be found right here.
I find it somewhat disturbing that in the year 2002, after we've put men on other planets, taken photos of galaxies millions of light years away and split the atom, we cannot determine the path of a plummeting object.
CNN (and other sources including NASA) are reporting a 9 hour window on when it could fall. With all the scientific minds and all the great algorithms we have, we can't determine when something like this will happen? Or is it that unimportant to bother getting out the slide rule and doing some calculations? And then there's where. A 1000 mile path that nobody seems to have any clue where it might land. We can't figure out a simple trajectory?
Doesn't this disturb anyone that chunks of metal up to 100lbs is going to be dropping on our heads shortly? True, the chances of getting hit are probably a billion to one, but they say that about lightning as well. Well, it'll be a fun light show and we can always hope it lands in Redmond or somewhere insignifigant.

The government is constantly getting in to trouble testing out their missles and other fun stuff...
This is the perfect time for them to test out some of their goods (i.e. anti-missle defense type stuff)...And at the same time prevent a rainstorm of 100lb metal bits.
And no one can complain about their weapon use because it can be written off as saving lives (or something...).

Yet space agency scientists said there is little risk because most of the doomed satellite will burn up in the atmosphere.

It's the end of my comment as I know it and I feel fine.
The Compton Gamma Ray Observatory had a requirement from inception to have a controlled reentry. Significantly, work started on it just a few years after the Skylab incident and NASA was probably concerned about dropping any more large objects on Australia. AFAIK nothing else currently in orbit has any reentry requirements. The ISS may, but I don't know about it.
Here are some stats for comparison

Being a drowning victim: one in 20,000

Can you tell me where a piece of paper dropped off a skyscraper will land?
The weather in low earth orbit is just as unpredictable as the weather at the ground, and just as variable. The density of the atmosphere around satellites (and thus the drag force on them) can vary by an order of magnitude. If the satellite loses orientation (which it is essentially certain to as drag forces overcome tidal or powered stabilization) then its coefficient of drag changes as well, and unpredictably when it rotates. It may not even have just drag acting on it; even in orbit an angled surface can produce just as much lift as drag, and when the satellite hits the atmosphere its shape could produce more lift than drag.
And of course, for every second by which the atmosphere delays reentry, the satellite has moved 5 miles in its orbit. 5 mi/s * 3600 s/hr * 9 hr gives a nice 160,000 mile strip of possible landing sites, crossing around and around the whole globe. If you'd like to gamble about the probability of something being hit by one of the chunks, though, I suggest placing your money on "no".
Considering how much it costs to send a pound of anything into space, it's too bad they couldn't just send it into geostationary orbit maneuver it to where a space station could get at it so they'd at least have the spare parts/metal up there.
Of course, my closet is full of old computer parts, so you see how I think.

Track the current satellite position on this Heavens-Above page. You'll see that the orbit is confined between 28 N and 28 S. Note that heavens-above doesn't compute reentry, but the position should be pretty accurate until the very last moment.
Space junk deorbits all the time. It just doesn't get the same publicity, some of the junk includes upper stage boosters including tons of fuel and a payload. The amount of rock naturally falling out of the sky is still more than the deorbiting garbage but nobody seems to worry about that, despite it destroying the occasional roof or car like these incidents:

In no event shall the designers of the satellite be liable for any direct, indirect, incidental, special, exemplary, or consequential damages (including, but not limited to, procurement of substitute goods or services; loss of use, data, or profits; or business interruption; destruction of cities, countries, continents; death of all humans) however caused and on any theory of liability, whether in contract, strict liability, or tort (including negligence or otherwise) arising in any way out of the use of this satellite, even if advised of the possibility of such damage.

The International Space Station is at an altitude of 400 km. Geostationary orbits are more like 36000 km, which is far beyond the reach of the Space Shuttle, which would be the logical (i.e., only) choice for collecting space debris and transporting it to ISS.

NASA's got a cool little Java applet you can play with to see the satellites and their orbits.
It's a simulation based on posted data, I gather, rather than any kind of tracker, and I'm sure there are dozens of black satellites not listed, but it's still very neat. You can zoom in/out and around the earth, pick specific satellites from categories, changes the time speed, etc. There's also all the favourites such as the shuttle (when it's up), the ISS, Mir, Hubble, COBE, etc. You can also load a web page with more info about any given satellite, such as when it was launched, what it carries, and so on.
Enjoy!

-- don't discount flying pigs until you have good air defense
I agree. However, this is extremely hard to enforce. What would the US government do if a foreign (Russian, Chinese, Japanese, French, you name it) satellite does not have this capability? 'Express their concerns' via diplomatic channels, or something less effective, I think. Clearly an international treaty would be required.
Many satellites are used for military purposes, and a reliable re-entry system would require reductions in the satellite payload and efficiency or increase the cost. I doubt most nations are not willing to let some international treaty to compromise their military interests. Considering the fate of the ABM treaty, it is pretty clear that United States is not one of them. Enforcing such a treaty efficiently would also require pre-launch inspections of all satellites, including the military ones. How many nations with space capabilities would allow this?
Due to orbital mechanics, it would take about 15tons of gas to move this 3.5 ton spacecraft into geosync orbit. Any when you get it there, it becomes like all those 5.25" floppy drives in your closet - i.e. obsolete, worn out and useless. i.e, the wrong sort of stuff. 3.5 tons of rocket propellent in GEO would be worth more than than the metal - many communication satellites up there eventually are retired due to running out of gas, even though the electronics has a few years life left in it. Remember, commsats are the only thing really making decent $$$ in space.

What, something falling out of the sky?
Yeah.
We get that fax once a week.
Yeah, but Donna doesn't know that. She thinks it's an emergency.
And you didn't want to tell her?
No, 'cause the other way you get a day's worth of entertainment without leaving the office.
She doesn't know that these things fall out of the sky all the time... once every ten days, as a matter of fact. Since the first year we started putting manmade objects in space 17 000 have come back, and remarkably not one person has been hit.
So I suppose there's an argument to be made that we're due.
Yeah.

I can't help but be confused. You repeatedly hear about the high cost of sending stuff into orbit. It seems to me that a little investment in creating some kind of space junkyard of sorts might pay off.
The same thing goes with Mir. We hear about how the ISS is so far over budget, but how come we let Mir crash and burn rather then integrating it into the existing ISS plan? Even if we ripped out all of its guts and let the vacuum of space kill the fungus that was growing in it, thats still a whole hell of a lot of metal that could possibly be pressurized and turned into a living/labrotory space.
But whatever.

Contrary to what a lot of people are guessing, EUVE had no onboard thrusters or fuel of any kind, so there is no way to control re-entry. The re-entry has nothing to do with the decomissioning, and everything to do with the fact that atmospheric drag is finally bringing it down. EUVE would have lasted longer in a higher orbit, but those are much more expensive, and it just wasn't practical. This is the case for the vast majority of low earth orbitting satellites (and especially inexpensive astronomy statellites that aren't out to make a profit).
Satellites like EUVE can change their pointing by spinning reaction wheels -- that's how the telescope was pointed at different targets all over the sky -- but merely rotating the satellite around does nothing to affect when it's going to re-enter.

I'm pretty happy I read it wrong. Although Microsoft never seem to hesitate to give us "some of the old in-out-in-out" whenever we dare to walk in the wrong parts of town.
...if it were steerable how many Linux hackers would be trying to gain control of it so they could nudge it toward Redmond...
I wonder if NASA will be required to pay for any damages of uncontrolled reentries if they occur.
5. Aircraft, including self-propelled missiles and spacecraft.
Who knows, maybe my insurance company would go after the spacecraft designers/operators/whoever -- or, more likely, after their insurance agency.
"Biped! Good cranial development. Evidently considerable human ancestry."
Now we get to see if the ABM hit-to-kill system is working...

This could make for a good test of a missle defense system.
Of course I really have no clue where the debris will land, but it sure would be fun to watch!
Maybe i should start selling insurance
When SkyLab fell back in 1979, this was the first of this kind of incident. People were concerned. The news said that if you check your homeowner's policy it usually has coverage for falling spacecraft.
I'll see your senator, and I'll raise you two judges.
Just picture a new section in the news programs:
Satellite weather.
"... Better take your umbrellas today, cause we expect satellites rain today in the morning..."
Are these things planned? Why not build in some retro rockets so it can be controlled when and where it comes down?
What if we dropped some of our (non-existent) space junk on the continental US?
We're your allies

I wonder when this sort of thing will start to be a more common event.
I forget which Max Headroom episode it was, started off with bits of deorbited satellites coming down. In a celebration of some sort.
Someone set us up the bomb, so shine we are!
Nobody mentioned the obvious. Why can't these materials be recycled? Burning on re-entry isn't a very environmentally sound solution.

NASA reports indicate that a 100lb piece of satellite traveling at 17000 mi/hr has a momentum of 8976*10^6 kg(m/s) :)
If this satellite's got MS in it, I'm amazed it stayed aloft this long 8)

help me i've cloned myself and can't remember which one I am
Has the Senate already asked NASA/Huge Tech University to create some potential math in the area of potential risk to being beaned by reentry objects?
Even if they have, what is the size of 6ish Billion people compared to the complete land area. Assuming 1/3 to 1/2 are sleeping (more surface space) versus sitting or standing?
In this equation, would you rule out certain areas due to orbit types? Seems that fun could be had doing the math!
TIA,

I think NASA should put up a remote controlled shuttle to grab these decaying satelites and push them off into space. NASA has no prob spending money on stuff. And this problem of satelites returning to earth will only become more common. - Bobby Mac
At 3.5 tons, this would be a '68 Buick doing re-entry instead of a Corvette. ~:D
Maybe this is that mythical guy that straped the RATO bottle to his car coming back to Earth?
With my current moderator status I was going to give this comment a clearly undeserved "fruitalicious" but then I wouldn't have been able to post to explain that it was just a joke...
