Pioneer 11

Target entity: Pioneer 11
Context triple: [Pioneer plaque project, spacecraft, Pioneer 11]

• A. Pioneer 10
  Pioneer 10 is a NASA space probe launched in 1972 that became the first spacecraft to travel through the asteroid belt and make a direct observation of Jupiter before heading into interstellar space.
• B. Voyager 1
  Voyager 1 is a NASA space probe launched in 1977 that became the most distant human-made object in space, conducting historic flybys of Jupiter and Saturn and now exploring interstellar space.
• C. Voyager 2
  Voyager 2 is a NASA space probe launched in 1977 that conducted historic flybys of all four outer giant planets and is now traveling through interstellar space.
• D. Voyager program
  The Voyager program is a NASA mission that launched the Voyager 1 and 2 spacecraft in 1977 to explore the outer planets and interstellar space, becoming one of humanity’s most significant and long-lived space exploration efforts.
• E. Pioneer plaque project
  The Pioneer plaque project was a scientific and artistic initiative to create and place engraved messages aboard the Pioneer 10 and 11 spacecraft, intended as a symbolic introduction of humanity to any extraterrestrial intelligence that might encounter them.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
