  • A. Landsat 7 chosen
    Landsat 7 is a NASA Earth observation satellite launched in 1999 that provides multispectral imagery for environmental monitoring, land use analysis, and global change research.
  • B. Landsat 5
    Landsat 5 was a long-lived Earth observation satellite that provided decades of multispectral imagery for environmental monitoring and land-use analysis.
  • C. Landsat 4
    Landsat 4 was an Earth observation satellite in the Landsat program that significantly improved global land imaging with enhanced sensors and higher-resolution data.
  • D. Landsat 6
    Landsat 6 was an Earth observation satellite in the Landsat program that failed to reach orbit after its 1993 launch, resulting in the loss of its intended remote-sensing mission.
  • E. Landsat 3
    Landsat 3 was an early U.S. Earth observation satellite in the Landsat program, used primarily for multispectral imaging of the planet’s surface in the late 1970s and early 1980s.
