Video: NASA releases construction time-lapse of SLS qualification tank
As the first flight of the massive Space Launch System (SLS) gets closer, more and more hardware is produced. In this multi-view, 60-second time-lapse video, NASA shows the creation of the 130-foot (39.6-meter) long liquid hydrogen fuel tank qualification unit at NASA’s Michoud Assembly Facility in New Orleans.
This qualification unit for the SLS core stage, which was completed last month, will be moved to NASA’s Marshall Space Flight Center in Huntsville, Alabama. There it will undergo structural testing to ensure flight-worthy tanks will be able to endure forces experience during launch.
In addition to the liquid hydrogen tanks, the SLS core stage will also have an oxygen tank. Together, the total length of the stage will be 212 feet (64.6 meters) long. For the flight-worthy units, four Space Shuttle-era RS-25 engines will be attached to the base. That, along with twin five-segment Solid Rocket Boosters, developed by Orbital ATK, will power the whole stack (with an upper stage and payload) toward orbit.
Currently, flight-worthy tank hardware is already under construction at other areas around Michoud.
The first flight, Exploration Mission-1, is expected to occur sometime in late 2018. It will send an unpiloted Orion spacecraft into space on a 3-week mission involving a retrograde orbit around the Moon. This will test all the systems necessary for the first crewed flight of SLS with Orion, slated to launch sometime between 2021 and 2023.

Derek Richardson has a degree in mass media, with an emphasis in contemporary journalism, from Washburn University in Topeka, Kansas. While at Washburn, he was the managing editor of the student run newspaper, the Washburn Review. He also has a blog about the International Space Station, called Orbital Velocity. He met with members of the SpaceFlight Insider team during the flight of a United Launch Alliance Atlas V 551 rocket with the MUOS-4 satellite. Richardson joined our team shortly thereafter. His passion for space ignited when he watched Space Shuttle Discovery launch into space Oct. 29, 1998. Today, this fervor has accelerated toward orbit and shows no signs of slowing down. After dabbling in math and engineering courses in college, he soon realized his true calling was communicating to others about space. Since joining SpaceFlight Insider in 2015, Richardson has worked to increase the quality of our content, eventually becoming our managing editor.
