back to article ISS crew flees flying space junk

International Space Station crew members were forced to flee to the outpost's escape capsule briefly on Thursday when a rogue piece of space junk came too close for comfort. The debris, a discarded mechanism used in boosting a satellite into higher orbit, missed the ISS without incident. The three astronauts took shelter for 11 …

Sheltering in a Soyuz?

S'OK if there's three bods in the ISS - but what happens when there are six? Two soyuz's? (What the plural for Soyuz is defeats me). Can one carry 6 souls or is it time to sing David Bowie's Space Oddity?

Maybe they should hide under that big piss-convertor that seems to be a white elephant at the moment, seeing as the STS has to bring up an unspecified spare part for it. (Maybe it's a smaller "collection tube" for the jap bloke...?)

sounds like the ISS needs a frigging laser :)

seriously, if you can mount it on a 747, there should be one on the ISS and any trouble some floaters or rogue astronettes with slippy finger could be vaporised (or at least their lost in space handbags).

A laser?

Nice idea, but what if they missed the targetted debris (travelling at 20,000mph), they could end up baking a small town on Earth somewhere!

It's clever how they can track so many pieces of fast moving debris so accurately, but it only takes 1 mistake or 1 unnoticed piece to seriously damage or destroy the IIS. Ultimately all the debris will need to be cleared so 1 of 2 things must be invented:

a) Force shields for all satellites and space craft

b) Unmanned craft that track and completely disintigrate debris with a new weapon or force it into the Earth's atmosphere to burn up.

Shield

I think they need to develop a shield as used to protect the Starship Enterprise.....

Perhaps they can use some of that alien technology out of area 51...

How about a high intensity magnetic field generator using supercooled magnets..wouldn't liquid helium to cool them out in space. Generate a massive magnetic field, induce a current in to the oncoming piece of metal ( assuming it's ferous, ok that's this idea blown..it's probably aluminium!) and deflect it..

What happens when there is no warning?

Sure they get warning when the object is 5 inches across, but can they detect a half inch object?

At those speeds a half inch object will whip through the ISS without blinking.

It is likely that small objects pass close by on a reasonably frequent basis but everyone just works on oblivious to the fact.

Re: A laser

Surprisingly, cooling things in space is much more difficult that it first appears. Having no air means there is bugger all contact or convection cooling, so any excess heat has to be lost as radiant heat. And for that you need big heatsinks with lots of surface area.

Stop

Hold your fire!

I do hope nobody actually installs a laser up there, because that wouldn't be very smart. It wouldn't vaporize anything, but turn one big piece of junk into hundread smaller ones. And the small pieces would have total energy (and thus speed) of what the big piece had plus anything laser managed to pump into them! So instead of one big dent on the side, ISS would have a hundread small holes, making it look like a sieve.

That is the problem with space junk. More you shoot it, more you get. More energy you spend, faster it gets (and thus making it able to reach higher orbits and do more damage). Only way to get rid of it is actually go up there and somehow collect it, possibly dropping it into the atmosphere afterwards. Or at least stop making more, as everything in near orbits slows down over time and thus plummets to Earth eventually.

This will be done in near future. Almost immediately after something really important gets hit, because tradition calls us to wait for the obvious to happen, before doing something to prevent it.

Thats because the three aboard are about as smart as seven of their average viewers.

How much safer in the Soyuz?

Since the debris could hit the soyuz with only a slightly lower probability than the space station, (presumably it's smaller, but just as vulnerable to being hit by a 20,000mph piece of junk), I wouldn't find it reassuringly safe in there. More a kind of whistling in the dark.

I Wonder.

All the crew got into the Soyuz escape capsule.......and stayed there. What would happen if the debris hit the Soyuz? Is it armoured and designed to withstand a worst case debris collision?

Maybe the Soyuz is positioned so the main station shields it from the flight track of most orbiting debris up there? A five inch chunk of metal traveling at 5 miles a second would punch through the ISS without stopping.

According to the article, they've had to shelter in the Soyuz five times so far. I suppose it's the 'least probable harm' option and I just have to admire them.

Speed

'The 5-inch chunk of metal is estimated to have passed by the station at nearly 5.5 miles per second (20,000mph)'.

So I assume this space junk was traveling across the ISS at 90degrees to the ISS's direction of travel or its speed in relation to ISS wouldn't be 5.5MPS. If that's the case then for them to near miss again would be extremely improbable. So logic tells me anyway.

I'll leave my worries by the doorstep now.

Relative?

The 5-inch chunk of metal is estimated to have passed by the station at nearly 5.5 miles per second (20,000mph).

Is that speed relative to the earth or the station? its not such a concern if its velocity is only say 5mph difference from that of the ISS...

Bear in mind that the Shuttle docks with the ISS In excess of 17,200 miles per hour (with respect to the earth). and this is normal!

Should've stuck it further up

So they are tracking the bigger than 10cm objects. That's not to say that a 1cm or even 1mm chunk of alloy traveling at 20,000mphs won't give them a seriously bad day.

So they can't (or don't) track anything smaller than 10cm? Can you imagine the damage a cricket ball would do if it hit at 20,000mph?? Let's hope it doesn't hit the Soyuz lifeboat...

@Sheltering in a Soyuz?

Seem to think that one of the extra modules that they want to fit before space shuttle stops is an extra Soyuz docking port for precisely this reason ... they want to increase crew but until they can dock another Soyuz then they are limited to 3 crew ... except when SS is also docked

Lifeboats

Just out of curiosity;

1. Dose it come with life jackets.

2. Do they have the little whistles on them too.

3. If it was used, would the nearest NASA shuttle be able to pick it up or just wait til it hits ground.

"wouldn't liquid helium to cool them out in space"

Actually, space isn't cold, there just isn't any atmosphere to hold/carry heat. Therefore any item that gets hot is going to get even hotter in space.

"Wouldn't a magnetic shield just attract any space junk?"

Not if in true Star Trek fashion you "inverse the polarity", then it would repel, but since there's no weight in space, I think that could also knock the ISS out of it's orbit.

title?

the one thing that seems to work well in space is solar power, would it be practical to make a huge electromagnet powered by solar power, send it in a low orbit, then any small pieces of crap up there would be attracted to it and it would change their orbits pulling them down and causing them to fall to earth much sooner than they otherwise would?

it wouldn't effect functional satellites at least, because they are rather large so the same force that might divert a screw probably wouldn't effect a satellite much

of course i have no idea how practical that would be, ie. how much of a difference a huge magnet 1 mile away would make passing in the opposite direction (so only at 1 mile very briefly) or of course how much of it is non-magnetic, but perhaps it is a possibility?

@Dave, Nah, it's a bit more serious that a Brown Alert, I'd ramp it up to a Beige Alert.

@Mike, Are you serious, a space junk collector/bin lorry, the ISS would spend all its time dodging the wheelie bins if my bin men are anything to go by. When they collect my bin, returning it to the kerb-side seems to mean an area anywhere from the middle of the road to the middle of my garden (via what ever is growing in the border) plus or minus 5 houses up or down the road.

Friday the 13th, it’s a wonder the junk didn’t hit the Soyuz

Paris, I’ll bet she could accommodate 3 men as well

Your best approach is a divide-and-conquer solution.

1) big things: track them continuously and take evasive manouvers^H^H^H^H^H^H^H^H action

2) medium things: pray

3) small things: vaporize on final approach

So that's one out of three covered so far.

Of course, we could just give up on manned space flight.

They don't know?

"Crew members have sheltered from debris in a Soyaz as many as five times in the past, NASA said."

"As many as"?!? Am I the only one bothered by the fact that NASA doesn't even know how many times the crew members fled to the escape pod? In other words, even NASA doesn't know what goes on up there. I'm so glad my tax dollars are hard at work.
