TSIS-1 has completed its 90-day commissioning activities, and will continue to learn about the very dynamic ISS environment for optimal operation. Starting March 5, 2018, TSIS-1 transitioned to Earth Science Mission Operations for 5 year mission with potential 2-year extension, after the project conducted the successful Post Launch Assessment Review on March 19.
