Infrared Astronomical Satellite

Target entity: Infrared Astronomical Satellite
Context triple: [NASA/IPAC Infrared Science Archive, missionArchiveFor, Infrared Astronomical Satellite]

• A. Compton Gamma Ray Observatory
  The Compton Gamma Ray Observatory was a NASA space telescope dedicated to observing high-energy gamma-ray emissions from cosmic sources, significantly advancing our understanding of phenomena like gamma-ray bursts, pulsars, and active galactic nuclei.
• B. 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.
• C. 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.
• D. SAS-2
  SAS-2 is a version of the SAS (Statistical Analysis System) software suite used for advanced data management, statistical analysis, and reporting.
• E. SAS-2
  SAS-2 was a NASA Small Astronomy Satellite launched in 1972 that conducted pioneering gamma-ray astronomy observations of cosmic sources.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
