The Orion spacecraft scheduled to fly around the Moon in 2018 was moved to a test stand to assess the structural integrity of the vehicle’s underlying structure—the pressure vessel.

The Exploration Mission-1 (EM-1) Orion was moved to the stand inside the Neil Armstrong Operations and Checkout Building on April 21 at NASA’s Kennedy Space Center in Florida.

Teams at Lockheed Martin and NASA will evaluate the structural integrity of the pressure vessel. It is an important milestone on the path toward preparing the spacecraft for launch atop the space agency’s Space Launch System (SLS) super-heavy-lift rocket in 2018.

EM-1 will be the first launch of an SLS and the second for the Orion spacecraft (the first was Exploration Flight Test 1 in December 2014).

If everything goes as planned, SLS will place the uncrewed capsule on a seven-day circumlunar trajectory and will test the fully integrated SLS-Orion system as well as validate the thermal protection system of the vehicle as it re-enters Earth’s atmosphere at speeds reaching an estimated 7 miles (11 kilometers) per second.

Throughout the United States and across the ocean, work is being done to prepare for this long-anticipated first flight of the SLS. Recently, at NASA’s Glenn Research Center’s Plum Brook Station in Ohio, engineers began testing a structural representation of the spacecraft’s service module with sound pressure and vibration.

Additionally, at Langley Research Center in Hampton, Virginia, engineers prepared a representation of Orion for a series of water-impact tests to evaluate crew safety after returning to Earth. The spacecraft is expected to splashdown in the Pacific Ocean off the coast of California after the EM-1 flight as well as future additional flights with crew aboard.

Finally, the flight-ready Orion service module, which is being developed by the European Space Agency, was delivered by Thales Alenia Space to Airbus Defence and Space in Bremen, Germany. Elements of the module will be integrated together there before being shipped to Florida to be assembled with the rest of the spacecraft. This is expected to take place sometime early next year.

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.
