Satellite Ops Engaged In 'Orbital Waltz' Around Rogue Satellite
SES World Skies attempting sophisticated maneuver to avoid problems
Potential disruptions from the rogue Galaxy 15 satellite have been minimal so far, though satellite operators are continually engaged in an "orbital waltz" in an effort to prevent any additional disruption. Though Intelsat can't talk to Galaxy-15 -- its electronics remain full functional, so it can easily disrupt signals from satellites whose orbital paths it wanders close to. To prevent this, companies like SES World Skies are engaged in a bit of space satellite choreography, which involves some fairly-sophisticated manipulation of other nearby satellites and the re-configuration of communications loads:
quote:
To ensure its TV customers experience no loss or degradation of service, SES plans on Tuesday to initiate a drift in AMC-11 to match that of Galaxy-15. It has also already commanded a second satellite, SES-1, to come in behind the damaged platform. Services will then be juggled between the two SES satellites until Galaxy-15 passes through the orbital slot and AMC-11 can return to its normal position and duties.
According to SES, maneuvers of this complexity have not been attempted before, but the company CEO says they're engaged in this very expensive and sophisticated space ballet because Americans "love their TV and it's important." Of course most Americans will be oblivious to the work these ladies and gentelemen are doing -- which should prove successful in keeping the zombie Galaxy 15's impact to a minimum.

I got a solution.

Ask the Chinese to shoot the satellite down. They have the technology.

Good one! Seriously, that would be the last thing they want to do. Then it becomes thousands (if not millions) of disruptive "satellites" that could pollute the magical geosync orbital plane.

What we need is some good ole fashioned British Petroleum engineering! If they could accelerate the satellite to leave the Earth's orbit and get caught in the moon's gravity...

Ummm...They don't seem to be having much luck lately.

Post of the day. And I agree.

Into a bunch of high speed debris (assuming they can hit a target that is over 40X the distance of their test target with enough force) which then can conveniently smash into other satellites - yeah, good plan.

I would suggest trying to EMP it. Although that would be hard as it's heavily shielded.

A longer term (and expensive) solution would be to send a booster rocket into to orbit to intercept the satellite and grapple it. Then the booster rocket could de-orbit the satellite.

You know the US has that technology too...and we can do it without causing thousands of pieces of satellite to pollute the orbits and endanger other satellites.

so..

what are the plans (if any) to remove or repair the sat? or is that just something they let float around till it crashes or something?

Re: so..

Can't be repaired (too far away) Can't (as yet) be shotdown (too far away, the chinese shootdown was a fairly low, 500 mile orbit)
This is ONE of the big dangers of a more crowded geo-sync band. and everytime another sat. has to move it uses valuable fuel shortening the life of that sat.
Best hope is some operator will use a NEAR EoL sat. to gently 'nudge' this one into a lower orbit. it will have to be a big operator with other assets in orbit to protect (using up the last year of fuel on a working sat is a very expensive choice), the danger being too hard a nudge and you have MANY hard to track debris, rather than one predictable rogue

Re: so..

I was thinking the same thing. It sounds like they're probably going to use up several months' worth of maneuvering fuel on AMC-11 and SES-1 for this one event, thereby shortening their useful lives:
"We have to do slight manoeuvres with our spacecraft pretty regularly, but a manoeuvre of this nature and complexity - no, I'm not aware of anyone having done this before," said Alan Young, chief technology officer with SES World Skies.
Should make for some interesting liability or compensation discussions, assuming there are multiple owners involved (article wasn't totally clear on that point).

Re: so..

Hard to do, there is NO specific liability, beyond the earth/atmoshere.
An international body has set the control of the "boxes" escentually an 100KM (each direction) of space per Sat in the clarke belt (around 22,500Mi from the EXACT center of the earth (varies every second (or less)) each sat onwer is responsible for their own sat, but exact law for rogues hasn't yet been tried.
My father-in-law spent years working on 1 of the NASA facilities that WAS tracking " manmade objects in space" only to see it shutdown (after his retirement, thankfully) for "private industry" trackers (ie using GPS, which relays on EXTREMELY accurate fixes of the earths center (gravitational versus the surface topography. (mostly checked by the Air Force now). They sort of for saw the day the clarke belt would reach the "too crowded to fail" point.

It's going to end up in the Sargasso Sea of Outer Space in a few months. It's got automatic programs to track the sun with it's solar panels, but eventually it won't be able to track anymore. Then it won't have a lot of power, and will finally stop broadcasting and go into low power mode, from which it will never wake up.

My Ideas

I suggested having the Chinese blow it up the first day the story broke.

Another idea I have is to get on older satellite that they want to get rid of anywy moving into position and 'bump' the galaxy satellite to a lower orbit where it be out of harms way and eventually get pulled down. Yeah a few pieces may fly off but that would be better than having a 5 ton satellite smack another 5 ton satellite.

Another idea would be to catch up to the Galaxy satellite with the space shuttle, catch it and bring it home...

Another ide would be to have the space suttle catch up to it. Do a space walk over to it and attach some rockets and fir it into the pacific ocean.

Re: My Ideas

Again, the shuttles MAX altitude was around 600 miles (usually around 110-230), WAY too low for the "clarke belt" that geostationary ( 22,300-22,600, on a good day) satellites reside. Besides the shuttle is WAY over committed for missions, the NASA cutoff is this year (if we are lucky, we MIGHT see 1 "extra" mission from Atlantis, in the fall)
No chance of a Geo-sync "rescue" EVER.

A fully intact satellite is easier to dodge than a bunch of pieces they can't see. One small fragment can ruin a satellite.

Sure. Turn one dangerous object into thousands of dangerous objects with unpredictable paths and orbits in some of the most important geo-spatial real-estate we have.

That's the WORST thing we could do.

What about the Space Station?

Why can't we collaborate something between the shuttle and the space station?

..or contact the Air Force and figure out what to do.

Re: What about the Space Station?

No way. The shuttle and the space station orbit a few hundred miles high, whereas Galaxy-15 is a geosynchronous satellite at around 22,500 miles high. A little out of the shuttle's reach.

Another trip to the moon? What about a satellite maintenance mission?

I'm sure a few satellite companies would be up for that.
