DARPA’s project to harvest parts from abandoned geosynchronous satellites.

My annual birthday-month fund-raising drive for Behind the Black is now on-going. Not only do your donations help pay my bills, they give me the freedom to speak honestly about science and culture, instead of being forced to write it as others demand.


Please consider donating by giving either a one-time contribution or a regular subscription, as outlined in the tip jar below.


Regular readers can support Behind The Black with a contribution via paypal:

Or with a subscription with regular donations from your Paypal or credit card account:

If Paypal doesn't work for you, you can support Behind The Black directly by sending your donation by check, payable to Robert Zimmerman, to

You can also support me by buying one of my books, as noted in the boxes interspersed throughout the webpage. And if you buy the books through the ebookit links, I get a larger cut and I get it sooner.

Salvage in space: DARPA’s project to harvest parts from abandoned geosynchronous satellites.



  • I applaud this effort, but I seem to recall a time when we could salvage entire satellites from orbit.

  • Roland

    NEVER from anything beyond Low Earth Orbit.

    Orbital dynamics is the death of many a good idea. Anyone have any insights on fuel requirements and deltaV changes that would help or hinder this from happening?

  • Pzatchok

    By the time this gets started they would have been better off just making satellites modular.

    Put together like LEGO’s. Got a bad solar panel? Just replace the thing.

    And everything, and I mean EVERYTHING would have to be modular. As soon as you have any part other than the frame that is not replaceable you mine as well just make the whole thing custom. Because as, Murphy’s law will always take effect, that one custom part will be the one to crap out first.

    Now that would require a repair robot be in the same orbit as the satellite and have the spare part available.

    Granted you would have to be patient enough to wait for the robot to get to the satellite and that could take a year using a low low fuel orbit change but it could be done.

    Everything would have to preplanned and preplaced into orbit. Otherwise its just a waste of a launch.
