MordhausI wonder if it can handle full speed?
BSRIf I understand what you're asking, full speed is relative. Anything in orbit is traveling at a fixed, known speed to keep it from falling back to earth or flying out into space.
Once drag is imposed on the object it will start to fall and it's course will change toward earth. It will start to fall faster and then burn up in the atmosphere upon reentry.
Interesting fact:
Let's say a gun is fixed to shoot a bullet parallel to the earth. At exactly the same time you shoot that gun, you drop a bullet from the same height as the gun, both bullets will hit the ground at the same time.
If that gun could shoot that bullet 7,500 MPH (+ -), it would never hit the ground if it wasn't slowed down by air resistance.
Hope this helps.

MordhausWhat I mean is that space debris travels at speeds up to 17,500 mph or slightly more, depending on what height it is orbiting at. If you place this device in the path (or near it) of a known mass of debris, it is going to have to adjust and fire that net at a speed relative to the debris. If you have the device speed up or slow down to try and match the debris speed, it is going to rise or drop it's orbit height comparatively to the adjusted speed.
That is what I am wondering, will this device be able to catch something travelling at that speed? I'm assuming it would have to try without excessive movement changes or it would require too much fuel.

newtboyI would assume, in it's current form, it has to be deployed in the proper orbit, direction, and speed to intercept it's target without much maneuvering on it's own. Perhaps eventually they'll make capture satellites armed with dozens of these that can chase down rogue objects and catch them, but as far as I know not yet by far.
