A new tractor beam technology based on laser thruster engines could be used to clear space debris from orbit.
The technology could be invaluable for clearing debris from orbit, in particular larger and more dangerous objects such as discarded rocket boosters that would pose a substantial risk to manned space vehicles if they were to collide.
Now a tractor beam could prevent the accumulation of space debris-including all the dead satellites, discarded rocket boosters and other junk-in the Earth's orbit, suggests an expert. Space-flight engineer John Sinko of Nagoya University, Japan, has put forward his idea based on an experimental type of spacecraft engine called a laser thruster.
