When satellites break, which is surprisingly often, there isn't much you can do about them. They become expensive and dangerous flotsam, orbiting Earth for years or generations until gravity eventually draws them to a fiery death in the atmosphere. University of Cincinnati professor Ou Ma is engineering robotics technology to fix orbiting satellites in his Intelligent Robotics and Autonomous Systems Lab. He envisions robotic satellites that can dock with other satellites for repairs or refueling...ASTRO WATCH · 1 week
