Landsat 9 Cross Calibration Under-Fly of Landsat 8: Planning, and Execution
During the early post-launch phase of the Landsat 9 mission, the Landsat 8 and 9 mission teams conducted a successful under-fly of Landsat 8 by Landsat 9, allowing for the near-simultaneous data collection of common Earth targets by the on-board sensors ...

Landsat 9 Geometric Characteristics Using Underfly Data
The Landsat program has a long history of providing remotely sensed data to the user community. This history is being extended with the addition of the Landsat 9 satellite, which closely mimics the Landsat 8 satellite and its instruments.

Initial Cross-Calibration of Landsat 8 and Landsat 9 Using the Simultaneous Underfly Event
With the launch of Landsat 9 in September 2021, an optimal opportunity for in-flight cross-calibration occurred when Landsat 9 flew underneath Landsat 8 while being moved into its final orbit.
