Triple

Target entity: New Frontiers program
Context triple: [Pluto Energetic Particle Spectrometer Science Investigation, program, New Frontiers program]

• A. New Frontiers program chosen
  The New Frontiers program is a NASA initiative that funds mid-cost, competitively selected planetary science missions such as the New Horizons Pluto–Kuiper Belt mission.
• B. Mir-NASA program
  The Mir-NASA program was a collaborative spaceflight initiative in the 1990s that sent American astronauts to live and work aboard Russia’s Mir space station, paving the way for later International Space Station cooperation.

  The Artemis program is NASA’s ongoing initiative to return humans to the Moon, establish a sustainable lunar presence, and prepare for future crewed missions to Mars.
• D. NASA Discovery Program
  The NASA Discovery Program is a series of competitively selected, cost-capped planetary science missions designed to achieve high scientific return with relatively small, focused spacecraft.
• E. Vision for Space Exploration
  Vision for Space Exploration was a mid-2000s U.S. space policy initiative that set long-term goals for human and robotic exploration beyond low Earth orbit, including returning humans to the Moon as a step toward Mars.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
