‘Tractor beams — the ability to trap and move objects using laser light — are the stuff of science fiction, but a team of NASA scientists has won funding to study the concept for remotely capturing planetary or atmospheric particles and delivering them to a robotic rover or orbiting spacecraft for analysis. This animation shows how a hypothetical future mission might eventually employ tractor beam technology.’
