Ground and gps guided unit to locate and use onboard compressed gas thrusters to catch up to space garbage within 1 kilometer. Onboard sensors guide the gotcha unit to within 3 meters. Telescoping rods extend. There will be 20 or so rods that can extend. Each rod has a star shaped (or irregular shaped as shown) that will apply enough pressure on the junk to call it a capture. Gotcha!
Now the main unit will use its compressed gas propulsion unit to guide into earth's orbit for burnup; or it can burn out of the earth's orbit to the sun's gravitational pull.
