报告内容摘要:体育平台 Tether (EDT) technology is a new type of propellentless propulsion technology that can lower or boost spacecraft orbits without consuming propellant. The EDT technology is based on two fundamental principles of electromagnetism: electrical current is produced when a conductive wire moves through a magnetic field, and the field exerts a force on the current carrying wire. One of the most appealing application of EDT is the space debris removal due to the advantages of propellentless, low mass, compact size, ease of use and low cost. This seminar will review the history of space tether missions, discuss the physical principles of EDT, explore the challenges and opportunities in orbit maneuvous application, and showcase our EDT mission – DESCENT (DEorbiting 体育平台Crafts using ElectrodyNamic 体育平台) from mission concept study, to mission objectives, nanosatellite design, hardware selection, and operation. The satellite was launched into orbit in November 2020 and decommissioned by the end of September 2021.
