The First Space Shuttle Rolled Out 50 Years Ago Today. It Never Reached Space — a Test Frame Went Instead

The first orbiter built became the most outdated one while the design kept changing. The one that flew in its place started life as a test article.

  1. NASA unveiled Enterprise, its first space shuttle, 50 years ago today. Star Trek fans had lobbied the White House for the name.
  2. The plan was to refit it for orbit after testing, but the design changed in the meantime and the refit cost too much. A converted test frame, Challenger, went instead.
  3. This is not a story about a useless prototype. Enterprise's landing tests helped prepare Columbia for the first orbital shuttle flight.

Tonight the Intrepid Museum in Manhattan marks 50 years since the public first saw a spacecraft that never went to space. Amit Kshatriya, NASA's associate administrator, is scheduled to speak. Former NASA Administrator Charles Bolden, who flew four shuttle missions, will join a panel. So will Peggy Whitson, who has spent more time in space than any other American.

The guest of honor is the space shuttle Enterprise. It sits in the museum's Space Shuttle Pavilion, white and familiar, the same shape as every orbiter that followed. It never left the atmosphere.

It is easy to assume that was always the plan. Enterprise was a test vehicle. It had no working main engines and no working heat shield to survive re-entry. But NASA never meant to leave it that way. Once the atmospheric tests were done, the agency intended to refit Enterprise and send it to orbit. Why that didn't happen shows how the first thing you build can be the first thing to go out of date. Anyone who has revised a report a dozen times can guess the ending.

A rollout set for the Constitution's anniversary

Rockwell International, NASA's orbiter contractor, started making Enterprise's first components on June 4, 1974, at its plant in Downey, California. Final assembly took place at the company's Palmdale plant. NASA planned to call the vehicle Constitution and to unveil it on Sept. 17, 1976, the anniversary of the day the Constitution was signed in 1787.

Star Trek fans had a different name in mind. They wrote to NASA and to President Gerald Ford asking for the name of Captain Kirk's starship. NASA's own history says that, by one account, the letters numbered in the hundreds of thousands. At a White House meeting on Sept. 8, Ford told NASA Administrator James Fletcher he was partial to Enterprise. Ford noted that the name had a long history in the U.S. Navy and was familiar to millions of Star Trek viewers. The meeting happened to fall on the show's 10th anniversary.

It makes a tidy story to say the fans renamed the shuttle, and the paperwork largely backs it up. A memo to Ford from a White House economic aide recommended the name as a response to the show's supporters, and Ford initialed his approval. The new name was announced the next day.

More than 600 invited guests and 185 members of the media came to the Palmdale rollout. As Enterprise emerged from the hangar, an Air Force band played the Star Trek theme. Series creator Gene Roddenberry and several cast members were there. Fletcher called it a very proud moment for NASA. The next day, more than 35,000 people came to see the new shuttle, dozens of times the size of the invited crowd.

Five flights on its own

In January 1977, Enterprise was trucked from Palmdale to NASA's flight research center at Edwards Air Force Base. There, NASA mounted it on the back of a modified Boeing 747. On Aug. 12, the orbiter separated from the jet for the first time and glided down to a dry lakebed. At the controls were Fred Haise, a veteran of Apollo 13, and Gordon Fullerton.

free flights Enterprise made on its own, from Aug. 12 to Oct. 26, 1977

There were five free flights in all, the last on Oct. 26. Each was an unpowered glide, and they were the only times Enterprise ever flew by itself. The tests checked whether an orbiter returning from space could land on a runway like an airplane. NASA used the results to prepare Columbia for its first orbital mission.

Next in line for orbit

Under the original plan, Enterprise would go back to the factory next. It would get the same engines, maneuvering thrusters and heat-shield tiles as Columbia. Then it would become the second orbiter to reach space.

That sounds like the cheaper path. The vehicle already existed, and it had already flown. NASA dropped the plan anyway. The agency's history gives the reason in a single line: modifying Enterprise cost too much.

Enterprise was given other work instead, helping NASA get the other orbiters ready to fly. In 1979 it stood on Launch Pad 39A at Kennedy so crews could check the facilities against a real orbiter.

The first one built kept the oldest design

The problem was timing. The design kept changing after Enterprise left the plant. While Columbia was being built, engineers revised the orbiter's structure to save weight. Bringing Enterprise in line with the rest of the fleet would have meant reworking its wings and fuselage in many places.

A lighter airframe leaves more of the rockets' lifting power for cargo. The lighter design let the orbiters from Challenger through Endeavour carry heavier payloads than Columbia. The change was worth making. The finished prototype paid for it.

Every office has the same problem. Open the file called draft_v1, and none of the later edits are in it. Rather than copy every change back into that file, you start from the latest version. Enterprise was the shuttle program's draft_v1.

A test frame became Challenger

The latest version already existed. It was a structural test article called STA-099, built to the lighter design. Computers in the 1970s could not confirm by calculation alone that a lighter airframe would survive launch and re-entry. So NASA built the real thing and spent a year shaking it and heating it.

Even the testing had limits. Loading STA-099 to 1.4 times its design limit would likely have deformed it past the point of flying. Engineers tested it to 1.2 times instead and checked the rest with models and analysis.

In January 1979, NASA signed a contract with Rockwell to turn the test frame into a flight vehicle. The job was not simple. The mock crew compartment had to be replaced with a real one, and much of the airframe was taken apart and rebuilt. Still, NASA says it was easier than converting Enterprise would have been.

Draft_v1 never went back to the factory. The latest version, built for the test stand, went to space instead.

The vehicle arrived at Kennedy Space Center in July 1982 bearing the name Challenger. It first flew on April 4, 1983. Counting that first trip, Challenger went to space and came back nine times.

Passed over again in 1986

On Jan. 28, 1986, Challenger broke apart during its 10th launch, and all seven crew members were killed. Enterprise, by then, had belonged to the Smithsonian for about two months. The fleet was suddenly one orbiter short. It is fair to ask why NASA didn't refit Enterprise anyway. The agency did consider it.

It chose another route. While building Discovery and Atlantis, NASA had ordered a set of structural spares in case an orbiter was ever damaged. Those parts became a new vehicle. Rockwell received the contract on July 31, 1987. The orbiter was Endeavour, and it first flew on May 7, 1992.

In 2003 the Smithsonian put Enterprise on display at a new center in Virginia. The orbiter moved to New York in 2012 and went on public display at the Intrepid on July 19 that year.

Most people never delete draft_v1. Nothing in it survives into the final version, but it is the one file that shows where the work began. Enterprise went out of date first because it was built first. It was left off the flight roster twice. It was also the first orbiter to enter a museum collection.
