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

Posted by timothy on Saturday September 1, 2012 @10:19AM from the frankenstein-program-stitches-them-together dept.

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."

  Space salvage would likely be similar to sea salvage. Once they are out of control the are open for capture and control because of the risk they represent to other satellites. Self destruct would be frowned upon as an open act of war due to shrapnel's ability to many other satellites including the space station at random. This would include spy satellites, either keep control, get them out of orbit, repair them or salvage them. Capture techniques are simplified in space because you have plenty of time to apply inertial energy to the satellites to get them to a capture point at acceptable motions and velocities, so even powerful electro magnetic fields and electricity generating solar sails with vector attitude adjustment would work.

  Some of them might. Satellites need fuel to stay in the right place, and to keep themselves pointing in the right direction (solar panels at the Sun, antennas at the Earth). It's called station keeping. Sometimes otherwise functioning communications satellites run out of fuel, and end up being useless because they're pointing the wrong way. Refuelling them can give them a new life. If there's still fuel but the thrusters or reaction wheels break, you have the same problem. That might be fixed by swapping these out. Micrometeoroid damages your solar panel wiring? If it's on the outside, perhaps a flying soldering iron can fix it.
  Obviously these are just ideas, you have to be able to get to the satellite first, and take up a fixed position relative to it even if it's rotating (see out-of-fuel above). That's what they're doing here. Then you have to grab it. There's some interesting work being done by Jon Goff and co. over at Altius Space Machines in essentially using static electricity to grab things in space, or electroadhesion. That seems pretty viable as well. Now we need satellites that are easier to fix up in space, or fancy tools to work on existing ones.

  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?

If it's broken, you don't necessarily know offhand what exactly is broken. If it's broken and hasn't been running in a long time, you don't know if there's additional things broken through age. There's possibly less certainty about remaining component lifespan on things that do work.
  Programmed components add additional complexity. Is access to the program code available? Are there ways to generate new program code for that part if needed?
  These are challenges that to a certain extent, can be overcome in-the-field, but it's horribly complex. Some of these challenges could be engineered to be reduced (for instance, things like standardizing on connectors, archiving and maintaining documentation, etc), but a lot of the problems will persist despite our best efforts.
  But this is why it's more complicated than the zero gravity, robotic version of egg catching (which isn't a simple thing in itself). I certainly applaud any efforts to tackle the issues.

  well, it's not wrong or overrated. He's right. To capture a dead bird all you have to do is match orbits. That's easy. Even travelling at 17,000mph, you can maintain a mutual closing speed of an inch a second, which is pretty damn precise. Slow enough that you can manipulate an arm to capture the bird at its launch/retrieval junction rather than just grabbing it at any random point (which would most likely destroy it rather than just cause a little damage).
  To retrofit a bird you have to switch out modules/circuit boards, replace solar arrays, refuel ACS tanks, etc., etc., etc. All of this is hard because most if not all satellites are built as fully integrated payloads (exception that pops into my head is the HST, which was successfully repaired in space for the simple reason that the instrumentation was built in separate modules). There are no user-serviceable components. No pop-out modules. The solar panels are hard-wired. And if you want to know how hard it is working in space, get on a treadmill and run hard for twenty minutes, then while continuing to run assemble a mechanical watch while wearing gardening gloves.

I think you are exaggerating the hurdles which must be overcome in order to do that. There are even simplifying factors, think clean room, pretty easy to achieve in space. I don't see the deal-breaker (ignoring costs) in docking such a module to the ISS (or yeah, fair enough, docking the ISS to such a module), in order to start manufacturing satellites right there. Recovering used satellites would serve the purpose off having potentially reusable parts right on-site. They wouldn't be needed to be 'hacked' into existing designs, they could just be considered for use in existing designs.

  The dangerous fraction of the space junk is all of the tiny fragments that have been left behind by, for example, anti-satellite missile tests (lookin' at you, China) among other things (lost bits and pieces, leftovers from stage separations).
  That fraction of the space junk can be further divided into the chunks that we can see and track, and the pieces that are too small to track and don't have known paths. It presents the biggest hazard because you can't always see it, certainly can't always dodge it, and it moves at tens of thousands of km/h relative to other satellites--that's a lot of kinetic energy.

DARPA to Rip Up Dead Satellites, Make New Ones by Hugh+Pickens+writes · 2012-09-01 13:57 · Score: 2

DARPA reports that more than $300 billion worth of satellites are in the geosynchronous orbit, many retired due to failure of one component even if 90% of the satellite works just as well as the day it was launched. DARPA's Phoenix program seeks to develop technologies to cooperatively harvest and re-use valuable components such as antennas or solar arrays from retired, nonworking satellites in GEO and demonstrate the ability to create new space systems at greatly reduced cost. "If this program is successful, space debris becomes space resource," says DARPA Director, Regina E. Dugan. However satellites in GEO are not designed to be disassembled or repaired, so it's not a matter of simply removing some nuts and bolts says David Barnhart. "This requires new remote imaging and robotics technology and special tools to grip, cut, and modify complex systems." For a person operating such robotics, the complexity is similar to trying to assemble via remote control multiple Legos at the same time while looking through a telescope. "If you've got a satellite up there already, don't worry, this isn't going to be some illicit grave-robbing mission to create hordes of evil Frankensatellites," reports Dvice. "DARPA says the agency will make sure and get permission before it chops anything up for scrap."

Re:if only we had some sort of reusable craft... by ColdWetDog · 2012-09-01 15:41 · Score: 1

If only we had some sort of reusable craft that could travel into space with a crew, use some sort of grappling arm to capture the satellite and return it to Earth.
I suppose one could dream.
Yeah, if only we had a manned space craft that could get to geosynchronous orbit. That would be cool.
The last time we had something like that was the Apollo program. The Shuttle (which I'm assuming you are referring to) only made it to LEO.

It was a great idea but it failed commercially by kriston · 2012-09-01 16:28 · Score: 1

It was a great idea but it failed commercially, somehow.
This was proposed as a viable service last year:
http://www.satellitetoday.com/via/dollarsandsense/38349.html
And even Via Satellite magazine published this piece which announced an agreement with at least one major satellite communications provider:
http://www.satellitetoday.com/via/features/37531.html
But early in 2012 they quietly announced termination of the agreement with said major satellite communications provider:
http://www.satellitetoday.com/satn/features/38192.html
So, I guess that today's development indicates that the technology is not commercially viable, but somehow needs more research? The sheer number of perfectly good bent-pipe satellites in geosynchronous orbit that are "dead" and moved to graveyard orbits for the sole reason that they have run out of fuel for station-keeping is staggering and should not be ignored.
Is this a good development or a bad one? MDA should have been given more of the benefit-of-the-doubt, or was there some other problem, either business-wise or technology-wise about MDA that we don't know about?
