Space Shuttle Atlantis (OV-104)

NASA's Space Shuttle Atlantis (OV-104) is the fourth operational orbiter, a reusable spacecraft used for satellite deployment, space station assembly, and crewed missions; now retired and on public display.

Space Shuttle Atlantis (OV-104) is one of NASA's reusable spaceplane orbiters and the fourth operational vehicle of the Space Shuttle fleet. Built for crewed access to low Earth orbit, Atlantis combined airplane-like controls with rocket engines and a large payload bay to launch, retrieve, and service satellites and space station components. The orbiter was named after a research vessel operated by the Woods Hole Oceanographic Institution.

Design and key features

Orbiter airframe: winged, reusable spacecraft housing flight deck, middeck, and life support for a crew.
Payload bay: a long cargo bay that carried satellites, scientific payloads, and station modules.
Propulsion and maneuvering: three main engines used at launch (fed by the external tank), plus orbital maneuvering system (OMS) engines for on-orbit burns and de-orbiting.
Thermal protection: heat-resistant tiles and reinforced carbon panels protected the vehicle during reentry.

Atlantis performed a wide range of mission types, from deploying satellites and scientific instruments to rendezvous and docking operations. Its capabilities made it a workhorse for construction and servicing tasks in low Earth orbit.

Operational history

Introduced in the mid-1980s, Atlantis entered service after testing and was used across more than two decades of shuttle operations. The orbiter supported science missions, commercial satellite launches in its early years, international cooperation programs such as Shuttle–Mir dockings, and major contributions to the construction and resupply of the International Space Station. Atlantis also flew the final flight of the Shuttle program in 2011, returning the fleet’s operational career to a close.

Legacy and public display

Following retirement from active flight, Atlantis was preserved as a museum exhibit and remains one of the most visible artifacts of the Space Shuttle era. It is displayed for the public at the Kennedy Space Center Visitors Complex, where visitors can view the orbiter and learn about its missions, engineering, and the people who flew on it. For official historical resources and mission archives see the NASA information page.

As a vehicle, Atlantis embodied the shuttle program’s blend of aircraft-like operations and spaceflight engineering. Its career illustrates both the promise and complexity of reusable human-rated spacecraft and continues to inform discussions about future crewed transportation systems.
