Chronology

Space Shuttle program

A high-level arc of the STS era—meant as orientation, not a mission-by-mission almanac.

  • 1972

    Program approval

    NASA receives a green light to develop a reusable space transportation system—what became the Space Shuttle.

  • 1981

    STS-1: Columbia

    First orbital flight of the Space Shuttle, proving the winged orbiter concept in space.

  • 1983

    Challenger joins the fleet

    Second operational orbiter expands flight rate and mission diversity.

  • 1984

    Discovery & Atlantis

    Additional orbiters strengthen logistics, science, and satellite deployment capacity.

  • 1986

    Challenger and STS-51L

    Loss of Challenger and crew leads to redesign of the solid rocket boosters and sweeping cultural reforms.

  • 1990

    Hubble deployment

    Discovery launches the Hubble Space Telescope—later serviced repeatedly by shuttle crews.

  • 1992

    Endeavour enters service

    A new orbiter built from structural spares replaces Challenger’s role in the fleet.

  • 1998–2011

    International Space Station assembly

    Shuttle missions deliver modules, trusses, and logistics that build the modern ISS.

  • 2003

    Columbia and STS-107

    Loss of Columbia and crew during re-entry reshapes thermal protection oversight and mission rules.

  • 2011

    Final flight

    Atlantis lands after STS-135, closing the Space Shuttle program after 135 missions.
