NASA has completed the final design review of an Earth observation satellite designed to fly for the U.S. Space Force, Space Ref reported Monday.
The space agency assessed multiple safety aspects of the Landsat-9 Evolved Expendable Launch Vehicle Secondary Payload Adapter or ESPA Flight System and concluded the final design review on Dec. 15.
The review verified the combined system's readiness for final integration activities. USSF's EFS would carry multiple satellite vehicles that will individually operate for civilian and national security missions. The Landsat-9 satellite will operate alongside EFS.
NASA plans to soon integrate the combined Landsat-9 EFS ahead of the launch scheduled for September 2021. Northrop Grumman designed and produced Landsat-9.
