The USGS and NASA recently held a successful Landsat 9 Ground System Critical Design Review (GCDR).
The review, evaluated by a NASA Ground Goddard Standing Review Team, met all the criteria for critical design, and in several cases, included content that was beyond the required criteria for his review. One official request for action and a small number of advisories were received. These will be addressed as Landsat 9 remains on track for a December 2020 launch.
Strengths of the GCDR review included low technical risk, talented team, good implementation of lessons learned, excellent relationship between NASA and USGS teams, and thorough programmatic processes. One of the next major milestones in the Landsat 9 mission development and lifecycle will be the Mission Operations Review which will occur in the summer of 2019.
