[Source: USGS Landsat] USGS and NASA officials will participate in the Landsat 9 Spacecraft System Requirements Review February 28 and March 1 at the Northrop Grumman facility in Gilbert, Arizona.
An independent panel will review the work of the spacecraft vendor to understand system requirements in a number of areas, including being able to control the orientation of Landsat 9 through attitude control, how much redundancy is built into the spacecraft, and how much fuel will be onboard.
Reviewers will also look at fault management capabilities, which include hardware and software features used to address any potential problems that may arise in orbit. This is the final such review before full-scale spacecraft design and development begins.
