Copernicus satellite (OAO-3)

Target entity: Copernicus satellite (OAO-3)
Context triple: [Far Ultraviolet Spectroscopic Explorer, successorOf, Copernicus satellite (OAO-3)]

• A. Infrared Astronomical Satellite
  The Infrared Astronomical Satellite (IRAS) was a pioneering space telescope launched in 1983 that conducted the first-ever all-sky survey at infrared wavelengths, dramatically expanding knowledge of stars, galaxies, and cosmic dust.
• B. Apollo Telescope Mount
  The Apollo Telescope Mount was a solar observatory module used on NASA’s Skylab space station to conduct detailed studies of the Sun in multiple wavelengths.
• C. International Ultraviolet Explorer
  The International Ultraviolet Explorer was a space telescope launched in 1978 that provided pioneering ultraviolet observations of astronomical objects for nearly two decades.
• D. Cosmic Background Explorer
  The Cosmic Background Explorer (COBE) was a NASA satellite mission that made precise measurements of the cosmic microwave background radiation, providing key evidence for the Big Bang theory and earning its scientists the Nobel Prize in Physics.
• E. Einstein Observatory
  The Einstein Observatory was NASA’s first fully imaging X-ray telescope in space, pioneering high-resolution X-ray astronomy of cosmic sources.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
