Target entity: Landsat 3
Context triple: [Landsat 4, precededBy, Landsat 3]
  • A. 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.
  • 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 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.
  • D. Landsat 7
    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.
  • E. Terra satellite
    Terra is a flagship NASA Earth observation satellite that carries multiple instruments to monitor the planet’s climate, land, oceans, and atmosphere from polar orbit.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
