The Deformable Mirror Demonstration Mission (DeMi) is a cubesat developed by the STARLab at MIT. It operated from 2020 to 2021 and tested a Microelectromechanical (MEMS) Deformable Mirror in space for the first time, raising its technology readiness level from 5 to 9. I was partly responsible for aligning the payload optics, and I also wrote and tested the wavefront control algorithm, which was successfully used in orbit (see Morgan et al. 2022 for details).
