NASA Researchers Aim to Reel In Tractor Beam Tech

NASA has given researchers at the Goddard Space Flight Center $100,000 to
look into making tractor beams a reality. The scientists will focus on three
techniques that could result in devices that can pull in objects from afar
using beams of energy. The studies could lead to technology able to clear the
space around Earth of debris that endangers spaceflight missions.
