Target entity: Landsat 7
Context triple: [Landsat satellites, hasMember, Landsat 7]
  • A. Landsat 5
    Landsat 5 was a long-lived Earth observation satellite that provided decades of multispectral imagery for environmental monitoring and land-use analysis.
  • B. 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.
  • 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 satellites
    Landsat satellites are a series of Earth-observing spacecraft that provide long-term, continuous multispectral imagery used worldwide for environmental monitoring, land-use mapping, and resource management.
  • 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.
