SFL Performs Passive Deorbiting with Drag Sails
Yesterday, the Toronto-based Space Flight Laboratory (SFL) announced that it has achieved a major milestone in debris removal: successfully deorbiting a spacecraft without the use of propulsion. The 24-year-old laboratory used a drag sail to deorbit a nanosatellite within five years from a ~688km altitude, ~178 years more quickly than it would have without the […]
