COSPAR ID 1999-020A

Target entity: COSPAR ID 1999-020A
Context triple: [Landsat 7, registration, COSPAR ID 1999-020A]

• A. Lunar Prospector
  Lunar Prospector was a NASA lunar orbiter mission that mapped the Moon’s surface composition and gravity field and provided strong evidence for the presence of water ice at the lunar poles.
• B. Giotto spacecraft
  The Giotto spacecraft was a European Space Agency probe best known for its close-up exploration of Halley's Comet in 1986.
• C. Spartan-Halley free-flyer
  Spartan-Halley free-flyer was an autonomous, reusable NASA spacecraft designed to study Halley’s Comet by conducting short-duration, targeted observations while deployed from and later retrieved by the Space Shuttle.
• D. Pegasus micrometeoroid satellites
  Pegasus micrometeoroid satellites were early NASA spacecraft designed to measure the frequency and impact of tiny meteoroids in near-Earth space to inform spacecraft shielding and safety.
• E. CASSIOPE satellite
  CASSIOPE satellite is a Canadian multi-purpose spacecraft that combines scientific research of Earth’s upper atmosphere with a commercial communications payload.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
