How this entity was disambiguated
This entity first appeared as the object of triple T16694621 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

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.
