  • A. Hubble Space Telescope Fine Guidance Sensors
    The Hubble Space Telescope Fine Guidance Sensors are high-precision optical instruments that both keep Hubble accurately pointed at astronomical targets and serve as scientific tools for measuring stellar positions and distances.
  • B. Hubble Space Telescope data electronics
    Hubble Space Telescope data electronics are the onboard systems responsible for processing, storing, and transmitting the telescope’s scientific observations and operational data back to Earth.
  • C. Hubble Space Telescope Servicing Mission 3A
    Hubble Space Telescope Servicing Mission 3A was a 1999 Space Shuttle mission that repaired and upgraded the Hubble Space Telescope to restore its scientific capabilities.
  • D. Corrective Optics Space Telescope Axial Replacement (COSTAR)
    Corrective Optics Space Telescope Axial Replacement (COSTAR) was a set of corrective mirrors installed on the Hubble Space Telescope to compensate for its flawed primary mirror and restore its intended imaging performance.
  • E. Hubble Space Telescope
    The Hubble Space Telescope is a large, space-based observatory that has provided some of the most detailed images and data about the universe, revolutionizing modern astronomy and cosmology.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
