DARPA's 'Phoenix' Program To Bring Satellites Back From the Dead

coondoggie writes "Scientists at DARPA say there are some 1,300 satellites worth over $300B sitting out in Earth's geostationary orbit (GEO) that could be retrofitted or harvested for new communications roles and it designed a program called Phoenix which it says would use a squadron 'satlets' and a larger tender craft to grab out-of-commission satellites and retrofit or retrieve them for parts or reuse." This program incorporates a design challenge aspect, in which various teams compete to design systems to effect the actual capture. From the article: "In the Zero Robotics challenge, three finalist teams emerged from a series of four, one-week qualifying rounds: "y0b0tics!" (Montclair, NJ); "The Catcher in the Skye" (Sparta, NJ); and "Nitro" (Eagleville, PA). Then in June the teams gathered at the Massachusetts Institute of Technology to watch via video link as their algorithms were tested on board the ISS, DARPA said. The algorithms were applied across three situations in which the SPHERES satellite simulated an active spacecraft approaching an object tumbling through space. In each scenario, at least one of the teams was able to approach the tumbling target and remain synchronized within the predefined capture region, DARPA said."

Maybe it's just me....

But isn't this technically a form of 'space salvage' or perhaps 'space piracy'? Did they get permission to retrofit these satellites from the owners? What's the 'abandonment period' for spaceborne objects to be considered 'up for grabs'? Assuming they're not already, how long until the military is using this either to capture and repurpose foreign satellites, or perhaps use them as disguised weapons to cause conflict between 3rd party nations?

And that's just what I came up with in the first 15 seconds of reading the summary.

I wonder if any of the "out of commission satellites" are actually full functional.

yeah disregard the mars..

Re:Capture is easy. Reuse is hard.

Capturing withough inflicting damage seems rather hard, a major part of it being the approach + synchronization with the satellite.

I was not trivializing the task accomplished. I was saying that when you look at the entire project goals, it's amongst the easier. If they simply return to Earth with the satellite, they'll oblitherate most of the cost benefits associated with recycling -- they still have to pay to launch again, and the payload will be used kit, not new. If they do it in orbit, they'll need to basically build a factory in space and mate it to a recycling center. To date, nobody's even attempted large-scale industrial process in orbit. It is a task that dwarfs the challenges of the ISS. We've also learned that things in orbit tend to accumulate fungus, and not a small amount either. There are modules on the ISS that frankly wouldn't meet health code if people lived on them here. When you consider all the obstacles involved in creating a functional assembly line for this kind of thing, and doing it in an economically viable fashion, yes, capturing is the easy part.

How would it be harder than the normal process of developing and deploying a sat?

Let me put it in terms you can relate to: If I walk into a recycling center, select twenty dead computers at random, disassemble them, and put them on a table, how many working computers can you make? Oh, each of those computers is 5 to 30 years old. They also contain explosives and occasionally radioactive material. Now realize that computers at least have standards for how they're supposed to fit together.
