Mercury spacecraft Sigma 7

Target entity: Mercury spacecraft Sigma 7
Context triple: [Mercury-Atlas 8, spacecraft, Mercury spacecraft Sigma 7]

• A. Mercury spacecraft
  The Mercury spacecraft was NASA’s first crewed space vehicle, designed in the early 1960s to carry a single astronaut into Earth orbit and safely return them, paving the way for later Gemini and Apollo missions.
• B. Gemini spacecraft
  The Gemini spacecraft was NASA’s two-person capsule used in the mid-1960s to develop critical spaceflight techniques such as orbital rendezvous, docking, and extended missions in preparation for the Apollo Moon landings.
• C. Mercury spacecraft Freedom 7
  Mercury spacecraft Freedom 7 was the capsule that carried astronaut Alan Shepard on the first American crewed spaceflight in 1961.
• D. Friendship 7
  Friendship 7 was the Mercury spacecraft in which astronaut John Glenn became the first American to orbit the Earth in 1962.
• E. Gemini 6A
  Gemini 6A was a 1965 NASA crewed spaceflight that achieved the first successful rendezvous between two orbiting spacecraft during the Gemini program.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: Mercury spacecraft Sigma 7
Target entity description: Mercury spacecraft Sigma 7 was the crewed capsule flown by astronaut Wally Schirra on NASA’s Mercury-Atlas 8 mission, a 1962 Earth-orbital flight focused on engineering tests and spacecraft performance.
