The idea of a gigantic magnet floating in outer space may suggest a low-budget space thriller, but it actually describes Japan’s efforts to take out the cosmic trash. Today, the country will launch its Space Tethered Autonomous Robotic Satellite-2, which has been designed to give Earth’s cluttered orbital space a long-overdue spring clean. The satellite works by using the Earth’s magnetic field to slow down bits of space debris. The junk then dissolves as it re-enters the Earth’s atmosphere. Once the old satellites, hardware and scraps have been cleared, contemporary missions will enjoy smoother star sailing.
