6U CubeSat with Deformable Mirror Demonstration Payload (DeMi)
Abstract
This document details the design, engineering, operation, and initial scientific data analysis of the Deformable Mirror Demonstration Mission (DeMi) CubeSat, a miniature space telescope that demonstrated MEMS DM technology in space for the first time. The DeMi payload contains a 50-mm primary mirror, an internal calibration laser source, a 140-actuator MEMS DM from Boston Micromachines Corporation, an image plane wavefront sensor, and a ShackHartmann wavefront sensor (SHWFS). The key DeMi payload requirements are to measure individual actuator wavefront displacement contributions to a precision of 12 nm and correct both static and dynamic wavefront errors in space to less than 100-nm RMS error. Data from initial wavefront control experiments show the DeMi payload correcting wavefront errors in space to less than 150 nm RMS. The DeMi mission raises the technology readiness level of MEMS DM technology from a five to at least a seven for future space telescope applications.
