"Dirty bomb"?
So, these hazardous materials it's carrying, do they include plutonium (as a power source)?
The US military is putting into effect contingency plans to deal with the possibility that a large spy satellite expected to fall to Earth in late February or early March could actually hit North America. Exactly what these contingency plans consist of is not clear at this stage - we thought perhaps a giant baseball mitt. But …
Send for Superman - another American invention LOL.
So much for global protection - what happened to all these so called missiles that are supposed to protect America - do they only work if they are fired at items not stamped "Made in America" ?
Be scared - be very scared - it's almost funny if it was not so damn dangerous.
It's very unlikely that it will carry plutonium. It was in Earth orbit, so it could have used solar panels to generate power. Plutonium is usually only needed for spacecraft such as Cassini, which have to operate much further from the Sun, where solar panels would need to be unfeasibly large to gather enough energy.
am I just paranoid?
Let's say, FOR EXAMPLE (as in Hypothetically speaking) a government wanted to give a black eye to another government without instigating WW3.
Ooh, one of our satellites is going to crash. Hmm, it might have a nuclear power cell which could destroy a few square miles and it might land in our back yard, but it could land anywhere really.
Sorry about that.
Oops.
Who said 9/11?
The so-called hazardous material is merely hydrazine.
BTW, the Russians, who are fond of putting full blow nuclear reactors on satellites, had one of those reactors crash in Canada. On January 24, 1978, the Russian Cosmos 954 reentered over Canada, with debris hitting the ground in frozen and scarcely populated areas in Canadian Arctic. They also had a nuclear reactor satellite, Cosmos 1402, fall uncontrolled January 23, 1983. Even when the Russians de-orbit one of their nuclear reactor powered satellites in a controlled fashion, they still have the reactor vaporize on reentry and spread nuclear contamination in the Earth’s atmosphere.
The US has never put a nuclear reactor into space. For deep space probes where the solar intensity is too poor to use solar power, the US uses radionuclide decay powered thermoelectric generators. (And yes, for those plutonium is a favorite choice.) For Earth orbit satellites, the US (and ESA) use solar power.
Just a number of things you could gain from a downed satellite. Not sure what the 'fail on deployment' is but here is a quick list.
1) Encrytion keys for existing comms or certainly the format, layout and rough method.
2) Capabilities
3) Comparison on power sources, quality of parts, reslience and structure.
You have to keep in mind that each country builds its military satellite 'blind' because you don't share that data with anyone (not even 'allies') so any insight into what others do would be priceless.
Even if you don't get much this would be major coup to get your hands on any of it, even if just for PR.
So this thing is *new*?! I thought it was some 30 year old cold war relic. Bloody hell. I can't imagine a better metaphor for government tech projects: A huge meteor flashing through a polluted sky, its message of catastrophic failure writ in letters of fire a mile high, pissing debris, cancer and wasted tax dollars across the entire nation.
PH because to her it'll signify the fury of her ancestors. I bet she sacrifices that poor dog/rat to appease the sky god.
Call Clint Eastwood and the rest of the gang; after all, they design this baby, they're the only ones who can fix it before it crashes, no?
We're also not supposed to know that its an old, cold-war era orbitting missile launching installation, but I think the cat's out of the bag now.
-dZ.
... you're just paranoid. If this had been a plan, they would have made *sure* it landed on the enemy, but it's not: it's going to land on them.
Unless of course their plan is for it to radioactively trash a few square miles of the USA, recover it and then "discover" that the reason it fell out of the sky was owing to something China did....
Anything you know about what powers a satellite won't be accurate. Apollo had plutonium batteries, not full reactors which wasn't a deep space probe and it came back.
Although solar is the norm now, it doen's mean there isn't a back up power source as this is a 24 hours military satellite which by it's nature isn't in the sun all the time.
Anyone thinks the US military is honest isn't really holding their full rack of marbles.
China and America have anti satellite missiles, dare say israel, japan, europe and russia have them. (Through purchase) and there is also the anti missile laser covered by the guardian a few years back.
...and for those conspiracy theorists the shuttle camera that was released that films behind the shuttle showing the laser beam coming from earth at the UFO trailing the shuttle (with the added sound of houston telling the astronauts to be silent as the world was listening to them) Remember the BBC program that showed it?
It's all PR and all smoke and mirrors at the end of the day.
I do wonder if America would put the effort into protecting Europeans from their problem, it only takes action when North american soil is in danger.
Call me a cynic.
"We know there is at least some percentage that it could land on ground as opposed to in the water."
I wish I was clever enough to make statements like that.
They don't know where it will land. Therefore it will either end up in water or on land. The world has xx% water (any number of people know the xx% except me). Could it be that the "some percentage" is xx%?
Why not just let it drop on Australia like they did with Skylab! If they chose the same spot again they would get away with only a fine of around $1150.
Assuming of course that you only add inflation to the same fine they paid for Skylab.
If it does indeed have anything radioactive then they only have to overshoot a few hundred km's and drop it where the British dropped their A-Bombs. Nobody will ask them to clean it up then.
Ohh this is just like Alistair McLeans Ice Station Zebra. It will land short in the Arctic and their will be a mad dash between the USA and USSR to get to the microfilm capsule, stuffed with military secrets, that has survived re-entry.
Can I be the British operative that saves the Yankie bacon whilst averting a face off with the Ruskies? And I want to command the submarine that gets them their.
Is that asking too much?
I don't know much about spacecraft, but surely a) the thing won't be heat-protected like the shuttle and so will fry on entry? Even if it doesn't completely burn up it'll probably damage irrevocably a lot of the electronic, and b) Be completely smashed to shit upon landing? Oh, and c) Be made useless by water if it falls into the ocean.
If I have to replace a laptop after dropping it 5 feet and killing it, I can't see how something falling through the atmosphere and then smashing into the ground at terminal velocity all the way from space is going to be much use to anyone.
I'd be more worried about where it's going to land.
Get the BOFH on this one - he hates trainspotters so just think of how he'd react to Satellite Spotting.
I'd be very surprised if this satellite was to land in Europe or somewhere that the US would give a damn. Only the chance of it crashing into The Pride Of The World spurrs them into action. As for recovering anything, it might be kinda mangled so I wouldn't think there'd be too much left to recover from the big smoking hole in the ground (33%) or the water (66%) - can there be a smoking hole in the water???
Just shoot the bloody thing down. You're telling me a Stealth Bomber can't get up to 60-odd thousand feet and launch a low yield nuke at it or something?
Superman is Canadian?????? Well I guess that's why he wears his underpants on the outside, eh? What's that aboot then?
What would Billy Ray Thornton and Bruce Willis do now... or Liv Tyler (well I'd do Liv Tyler but that's another story).
Paris Hilton because... well she looks good, it's only when she talks the trouble starts. So I guess there's only one thing left to do with her mouth.
So lets hope it does not hit one of the bigger oil tankers.
As a yachsman it annoys me "slightly" that the sea is considered compleatly safe for dumpping any size of space rubbish. Perhaps the reason is that there probably will be no evidence left of an accident.
About Superman:
Superman is a fictional character, a comic book superhero widely considered to be one of the most famous and popular such characters and an American cultural icon. Created by American writer Jerry Siegel and Canadian-born artist Joe Shuster in 1932 while both were living in Cleveland, Ohio, and sold to Detective Comics, Inc. in 1938,
The most stupid part of this is that they didn't actually design the satellite to burn up properly. Ask any reader of spy novels and comic books: First rule of secrecy/spy work is to be able to destroy your secrets: cyanide capsules, write on rice paper so you can swallow it etc. Some creative thought involving explosives and a temperature sensor would have been a good idea.
I doubt very much that you could get useful encryption keys or any such off this beastie. Those won't be written on a label like a MAC address on a router or on a bit of paper stuck inside the service door. About the only thing you could get that would be interesting is knowledge of the capability level and perhaps some stuff like optics etc.
The US are terrified of crashing these things on own soil and damaging an SUV or giving someone split ends. They also don't want to crash in Asia (they'll copy the satellite, except make em smaller and in three diferent colours) or Europe (damn commies). That's why they control-crash most of their stuff here in the Southern Hemisphere with lots more water and only a few of us sheep/goat worriers who aren't the complaining type. If Skylab is anything to go by, then most people would welcome the satellite. The Skylab finder made quite a bundle and they had it as a prop on Miss Universe.
I haven't checked but is the next Miss Universe soon? [PH coz she'd know]
Actually America has orbited one nuclear reactor - the SNAP 10 in 1965 which was injected into a low polar orbit for 43 days before an unrelated failure caused the automatic ejection of the core into a higher storage orbit.
The US abandoned nuclear reactors on satellites fairly early as it perfected efficient solar cells for its reconnaissance satellites. They could put their satellites further out where solar arrays were less prone to atmospheric drag and make up for the greater distance with superior optics.
They continued with radioisotope generators (RTGs) on missions to the Moon (to get round the 14 day Lunar nights) and outer planets; but it's worth remembering that two American RTGs been lost when coming back to Earth...
In 1964 an RTG was launched on the unsuccessful Transit 5BN mission. The RTG burned up over Mozambique releasing something like 50,000 curies (1 metric shed-load) of plutonium 238 into the atmosphere. This led to a change in American RTGs to use ceramic plutonium and graphite construction. Which was handy when Odyssey, the Apollo 13 Lunar Module (which was meant to be left on the Moon) came back to Earth and burned up in the atmosphere. NASA deliberately steered the craft into the Tonga Trench in case its RTG leaked. Later surveys found no sign of contamination.
The Soviets not only continued using nuclear reactors in their radar satellites, their radars and solar cells were relatively poor requiring very low orbits where atmospheric drag would have brought a solar-powered craft back to Earth presto pronto, but they also used polonium 210 to heat some of their lunar missions. IIRC one of their Lunokhod missions never made it out of Earth orbit and eventually burned up along with its exciting cargo.
" They don't know where it will land. Therefore it will either end up in water or on land. "
Well, it could end up in-between. Assuming it lands somewhere in the vicinity of Scarborough fair, that is.
Yes, that's my coat. The cambric one on the peg over there, smelling of mixed herbs.
Satelite the size of a bus that won't burn up in the atmosphere....thats a hell of a camera. I'm not claiming to have built any spy satelites myself but if you're going to build it as big as a bus you might aswell fit it with backup engines.
And why doesn't it have some form of self destruct, wouldn't take much more than just opening it's case as it came in the atmosphere.
"Although solar is the norm now, it doen's mean there isn't a back up power source as this is a 24 hours military satellite which by it's nature isn't in the sun all the time."
yeah because all geostationary satelites go offline overnight don't they. can't wait till summer when sky can broadcast past 5.30pm in the evening...
psst if you don't get sarcasm, they've got batteries that are charged in the sun.
“The so-called hazardous material is merely hydrazine.”
You are a fucking idiot. Hydrazine is HIGHLY biologically hazardous to anything alive that comes in contact with it. Go have a paddle in it, Admittedly, most of it will vapourise on re-entry but what if a tank of it comes down in a populous area?
“The US has never put a nuclear reactor into space. For deep space probes where the solar intensity is too poor to use solar power, the US uses radionuclide decay powered thermoelectric generators. (And yes, for those plutonium is a favorite choice.)”
Officially. There are in fact several probes (both military and civillian) now carrying plutonium thermocouple reactors.
The US abandoned nuclear reactors on satellites fairly early as it perfected efficient solar cells for its reconnaissance satellites. They could put their satellites further out where solar arrays were less prone to atmospheric drag and make up for the greater distance with superior optics.
These things are as big a buses because of all the fuel they carry. It's either that or plutonium firing helium discharges.
The fuel is for overcoming gravity anomalies and friction. They use tiny amounts of fuel to correct the orbit or to change it to suit a topical event.
Having failed to locate it properly they probably used up most of the fuel intended for minor orbital correction on getting its error corrected. Or tried to.
Larger or more modern solar panels will only have served to cut size and weight. Most of the 24/7 ability would have come from rechargeable batteries. Early varieties built up a problem locking into a poor charge cycle due to the regularity at which they were drained and charged.
That problem gave rise to the idea that power packs on earth need to be fully drained before they are recharged.
"We know there is at least some percentage that it could land on ground as opposed to in the water."
Roughly around the same percentage of land to water covering the surface of the earth maybe?
Oh and I like how they have contingency plans IF it hits North America, does that mean they don't really care if it takes my house out?
He was neither solely an American or Canadian creation - In fact, Superman (Kal-El) was created by American writer Jerry Siegel and Canadian-born artist Joe Shuster in 1932. He is of course not from either of these countries, but the last son of the planet Krypton and biological son of Jor-El and Lara Lor-Van.
Where is he when we need him though? Man of steel my arse!
"The US has never put a nuclear reactor into space. For deep space probes where the solar intensity is too poor to use solar power, the US uses radionuclide decay powered thermoelectric generators. "
What is the actual difference between a nuclear reactor (used to generate electricity) and an generator powered by nuclear decay?
And how important is that distiction when we're worrying about what might spill out of the satellite if it lands on us?
"They continued with radioisotope generators (RTGs) on missions to the Moon (to get round the 14 day Lunar nights) and outer planets; but it's worth remembering that two American RTGs been lost when coming back to Earth..."
The Moon is tidally locked to Earth, the same side is always pointing to Earth. Where you land if its day, it'll stay day, no 14 day nights...
"The Moon is tidally locked to Earth, the same side is always pointing to Earth. Where you land if its day, it'll stay day, no 14 day nights..."
OK, I'll explain this slowly.
Imagine I'm standing in the middle of a room, with a bright light shining on me from a lamp in the corner.
You enter the room and face me, then start sidestepping around me in a circle. Is the light always on your face?
Think about it...
Think about it...
... "Dark side of the Moon" - there is only the side we can't see from Earth! Full moon = sun on the side we can see (dark (or night) on the side we can't); new moon = shadow on the side we can see (light (or day) on the side we can't). Full night at any given point on the Moon is about seven Earth days.
Because the best way to minimize damage from a falling object is to make lots and lots of falling objects!
I especially like the low yield nuke comment. Radioactive falling objects! Yay!
The ignorance in these comments is astounding.
"The Moon is tidally locked to Earth, the same side is always pointing to Earth. Where you land if its day, it'll stay day, no 14 day nights..."
Go outside every few days, and look at the moon. Keep in mind your always seeing the same side. You might notice something - its not always a full moon.
