ORBITER
A FIELD GUIDE TO THE SPACE SHUTTLE PROGRAM
Nine chapters on the vehicle that flew like a spacecraft going up and a glider coming down, carried the pieces of the International Space Station into orbit one payload bay at a time, serviced the Hubble Space Telescope five times by hand, and flew 135 missions across thirty years — a run defined as much by two catastrophic losses as by its triumphs. Scroll to begin.
BEGIN — CHAPTER 01 →Every crewed spacecraft before it flew once and was thrown away
Mercury, Gemini, Apollo, and Soyuz capsules were all single-use: a splashdown or landing ended their flying life. The Space Shuttle's orbiter was designed to return to a runway landing and fly dozens of times, refurbished between missions rather than replaced.[1]
That single idea shaped everything about the vehicle: wings for a runway landing, a cargo bay big enough to carry satellites and space station modules, and a fleet of orbiters rather than one spacecraft built once.
No uncrewed test flight — just two astronauts and a new kind of machine
STS-1 launched on April 12, 1981 — twenty years to the day after Yuri Gagarin's flight — with John Young and Robert Crippen aboard Columbia. Unusually for a new spacecraft, its first flight was crewed from the start, since the shuttle could not be adequately tested any other way.[1]
One reusable orbiter, riding two boosters and a tank it threw away
Only the winged orbiter came home. The tank and boosters either burned up or were fished out of the ocean for reuse. Select a component.
The cargo bay that carried a space station up in pieces
The shuttle deployed the Hubble Space Telescope in 1990 and returned to service it by hand five times, the last in 2009, keeping it working and upgrading its instruments decades past its original design. From 1998 onward, shuttle missions carried up most of the modules and trusses of the International Space Station, assembling in orbit a structure too large to launch in one piece.[1]
A rubber seal, stiffened by cold, that was never meant to be tested that way
On January 28, 1986, Challenger broke apart 73 seconds after launch when cold-stiffened rubber O-rings in a solid rocket booster failed to seal properly, letting hot gas burn through and trigger a structural failure. All seven crew members, including teacher Christa McAuliffe, were killed.[2] The disaster grounded the program for nearly three years while the boosters were redesigned and launch decision-making overhauled.
Damage from launch went unnoticed until the ship tried to come home
On February 1, 2003, Columbia broke apart during re-entry. A piece of insulating foam had struck and cracked the wing's thermal protection during launch sixteen days earlier; over the intense heat of re-entry, superheated gas breached the wing and destroyed the vehicle. All seven crew members died.[2] The program was again grounded for over two years, this time with new procedures for inspecting the orbiter for damage while still in orbit.
Redesigned hardware, and a program that chose to keep flying
After Challenger, the shuttle returned to flight in September 1988 with redesigned booster joints and a new independent safety office. After Columbia, it returned in July 2005 with a redesigned external tank and, for the first time, the ability to inspect and, if needed, repair heat-shield damage in orbit.[2] Each disaster reshaped how the program judged risk far more than any single engineering fix could.
Nine years buying seats on Soyuz to reach the station it helped build
Atlantis flew the program's 135th and final mission, STS-135, landing on July 21, 2011. With no domestic replacement ready, NASA relied entirely on Russian Soyuz spacecraft to carry its astronauts to the ISS for nearly nine years, until SpaceX's Crew Dragon flew its first crewed mission in 2020.[1] The surviving orbiters went to museums across the country.
The bridge between capsules and commercial spaceplanes
The shuttle proved a winged, reusable spacecraft could fly for decades — and that reuse alone does not make spaceflight routine or cheap. Both lessons shaped the vehicles that came after it.
