@Ropemancer It's cheaper to leave the bulk of the retired satellite at GEO. The costs saved here are the antennae that don't have to be brought out of the well because they're already outt. The most expensive thing about satellites is getting them up there in the first place.
Normal "space junk" is a serious problem, but that's more for objects in the LEO neighborhood, which is way closer than GEO. But if this proposal gets off the ground, so to speak, this would be perfect technology for that.
@singedrac Ok, now it's more clear to me. But what with those detached antennae? Are they plan to build a new sattelite right up there, or what? From this video a saw a few antenaes placed in space but what for? Thanx in advance. :)
@Ropemancer "But what with those detached antennae? Are they plan to build a new sattelite right up there, or what?"
I imagine they plan to send up new satellites that don't have a big antenna, to save cost on weight, then attach an antenna from the farm to the new sat. The electronics are unimportant. What matters is the huge heavy metal parabolic mirror of an antenna already being in orbit. :)
The DARPA SATELLITE HAS GONE ROGUE! It's cannibalising the ISS! A small group of astronauts left to try and stop the machine before there's nowhere safe left on the station. In the third act we discover what the Phoenix was using the parts to create! HORRIBLE REVELATION!

So, I have long had this idea where you would use a railgun system to launch big canisters of water into orbit. A robot will come along and collect these, placing them in a LEO "service station" where orbital vehicles could top off their fuel tanks (it would crack the water using solar power). They only need carry enough fuel to get back up and down safely. After all, you don't take every liter of gas with you on your trip to Yosemite.
@chassoto wait do u mean fuel or water? both could be usefull up there but one major problem is the railgun would be quite masive to launch anything sizable enough lk most railguns launch small projectiles only around a few pounds or so. still not bad idea though
@bosskid71 Fuel can be water! LOX and LH2 are commonly used as fuel in rockets, or they can power a fuel cell with the output as water. Not to mention, water itself can be a useful reaction mass.
Anyway, there've been proposals to make orbital railguns. I don't think there's any serious technological limitations in doing so, it just hasn't been done. It wouldn't work with humans or other delicate things, perhaps not even with your usual sat. But big tanks of homogenous material? Sure!
@bosskid71 For most (non "booster") rocket motors, water IS the fuel. Also, you're thinking about weaponized "gauss cannons." There have been ideas to have magnetic launch vehicles run up the side of a mountain or out of an underground silo (think the old sci-fi movie "When Worlds Collide" though they used a "rocket plane" design). The problem with those vehicles is they generate a lot of G-forces, so they're not appropriate for sensitive things (like humans). Water doesn't care.
@chassoto@chassoto Ahh ive heard of those, i think they are called mass drivers. another problem is that would cost alot of money. to have enough length of track for orbit would be pretty expensive. but if we could do that we could send alot of raw material for large scale space vehicles. building them in space then sending somthing lk the russian soyouz for the crew. that would work well with the plan of an orbiting fuel depot.
I have some other similar concepts I am willing to share with anyone on the team, so contact me. My concept is similar however it uses a Whipple Shield sandwhich composite system to trap and catch the debris. Then it could be taken into an orbiting clean room assembly for tele-robotic re-assembly.
so imagine the "pods" are explosives or can capture all data going thru the antenna. This seems more like a counter satellite measure and I can also asume that the new space plane x-37 does these same manuvers. Is this Star Wars?
great idea guys could tidy up and reuse some of the junk wizzing about up there much better use of your skills than boring weapons KEEP IT UP earth needs guys like you to think out the box for good stuff :-)
that's interesting, but i want to help our government with quantum physics (antigravity, teleportation, materialization, force fields, etc)

@Ropemancer It's too expensive to take the thing to earth. There isn't enough fuel.

They're not interested in the circuitry, just the physical dish itself.

I'm interested to know how an arbitrary antenna can be repurposed without knowing the specifics of or having access to the circuitry within.
