Using Sling Shot Power to Hurl Into Orbit

the_2nd_coming writes "space.com has an article about a new application of a very old technology. NASA is putting money into Momentum-eXchange/Electrodynamic Reboost tether technology -- MXER for short -- an innovative concept that if implemented would station miles and miles of cart-wheeling cable in orbit around the Earth. Then, rotating like a giant sling, the cable would swoop down and pick up spacecraft in low orbits, then hurl them to higher orbits or even lob them onward to other planets."

  1. SciFi does it again by PaulK · · Score: 5, Insightful

    It seems that the greatest two motivators of technology are SciFi authors, and sales people.

    This approach was used by Robert Heinlein in several books; it is a pleasure to see his vision honored.

    As for sales people, I can't count the number of times that I have had to create what they have sold.

  2. Degrading Orbit by sublimusasterisk · · Score: 5, Insightful


    I noticed on one of the diagrams that the orbit of the slingshot itself degrades after each launch pick-up. Maybe the decrease in orbit isn't very significant, but would this system require self-adjustment? How would the system stay in service over the long term?
