Engineering Test Satellite series

Target entity: Engineering Test Satellite series
Context triple: [H-IIA launch vehicle, launchesNotablePayload, Engineering Test Satellite series]

• A. Tactical Satellite Program (TacSat)
  The Tactical Satellite Program (TacSat) was a series of experimental U.S. military satellites designed to rapidly demonstrate and deliver responsive, tactical space capabilities directly to battlefield commanders.
• B. Alouette satellites
  The Alouette satellites were pioneering Canadian scientific spacecraft launched in the 1960s to study the ionosphere, marking Canada as one of the first nations to design and build its own satellite.
• C. GSAT-1
  GSAT-1 is an Indian communications satellite that served as the inaugural payload for the Geosynchronous Satellite Launch Vehicle (GSLV) program.
• D. CubeSats
  CubeSats are a class of miniature, standardized modular satellites typically used for low-cost space research, technology demonstration, and Earth observation missions.
• E. Tracking and Data Relay Satellite-B
  Tracking and Data Relay Satellite-B was a NASA communications satellite intended to relay data between spacecraft in low Earth orbit and ground stations as part of the Tracking and Data Relay Satellite System (TDRSS).
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
