Senate Resolution 721 officially commemorates the 50th anniversary of the Landsat program, a joint initiative between NASA and the U.S. Geological Survey that provides continuous global images of Earth’s surface. The resolution recognizes the program’s scientific achievements and designates July 23, 2022, as "Landsat 50th Anniversary Day" (or "Landsaturday").
