On April 12, 1981, astronauts John Young and Robert Crippen launched on Space Shuttle Columbia, about nine years after Young was walking on the moon. You would be right if you sensed a pattern with new spacecraft and launch delays. 'When you look at STS-1 through that lens, and you look at where we are, we're very much within family with that experience,' Blackwell-Thompson said.Īfter a computer error caused the STS-1 launch attempt to scrub on April 10, 1981, the mission lifted off two days later. She estimated that the STS-1 booster was tanked about five times and underwent 12 static fires at Stennis Space Center before it actually launched. More than 40 years later, Artemis I Launch Director Charlie Blackwell-Thompson said during an April 18 media briefing she has two engineers who worked on STS-1 now working on the Artemis I mission. During a WDR, NASA’s launch control runs through the countdown and fuels the rocket just as it would on launch day, but the rocket does not fire up.īefore the space shuttle’s first orbital flight, one WDR was completed in February 1981 at Kennedy Space Center, but it also included a flight readiness firing, where all three orbiter engines were fired up, but the vehicle stayed firmly on the ground. NASA conducted four wet dress rehearsal (WDR) tests with the SLS before moving toward a launch attempt. NASA's SLS rocket stands ready for the Artemis I mission late Sunday night, August 28. The four RS-25 engines built by Aerojet Rocketdyne on the SLS core stage are formerly known as Space Shuttle Mains Engines. This time, with SLS, NASA is starting over with almost everything but the engines. Launching the orbiter was an entirely new vehicle.

'It was two years putting Humpty back together again,' Myers recalled. HERE'S WHY THE ARTEMIS 1 LAUNCH WAS SCRUBBED MONDAY NASA contracted Rockwell to build the orbiters for the space shuttle program.

James Myers, a retired space shuttle engineer for Rockwell and Aerojet Rocketdyne, called it a 'nightmare,' spending two years putting the tiles back on the orbiter. STS-1’s original launch date was targeted for November 1979, but it didn't launch for another two years, according to .īefore launching, the orbiter Columbia spent 610 days in the Orbiter Processing Facility, where teams replaced heat shield tiles. That’s why NASA is conducting the Artemis I test flight without astronauts before flying a crew, possibly next year. NASA’s new human spacecraft Orion can fly autonomously.
