On November 17, 2021, the international top scientific journal Nature published the results of in-orbit demonstration tests of thrusters carried on The Tianyi satellite, according to tianyi official news. This paper shows the successful test of iodine electric propulsion system of Tianyi satellite in space, which successfully completed the first successful flight of the world's first iodine electric propulsion system. It proves the feasibility of iodine as propellant of electric propulsion system, which is an important step in the commercial application of iodine electric propulsion technology in the field of space and has a milestone significance.


Iodine is the ideal fuel for small satellite electric thruster. Due to the difference between space environment and ground environment, the working state of iodine ion beam in space and ground is very different. To electric propulsion, validation, iodine in space environment, day instrument research institute and the French gen ThrustMe cooperative enterprises, the instrument use day north aviation satellite no. 1, on November 6, 2020 success will ThrustMe developed the world's first electric propulsion of iodine into space.


Tianyi satellite platform not only comprehensively upgraded attitude control, power supply, communication and mission planning, but also fully met the requirements of space testing of iodine electric thrusters. At the same time, the celestial instrument technical team also provided perfect technical support for the in-orbit test. In six months, more than 200 orbital maneuverings were conducted, and the positive and negative changes of the semi-major axis of the orbit accumulated more than 60km.


Understands IT's home, with the success of the experiment verification, also make the day meter satellite has long time continuous rail control ability to meet the requirements of various mission, and the cost is much lower than conventional xenon fuel electric thrusters, enables day meter satellite platforms at a lower cost for the space scientific research users with better service.

The successful partnership between ThrustMe and Astro is expected to bring more iodine-powered satellites to the space market.
