HOUSTON, TEXAS |  In a lab at NASA’s Johnson Space Center in Houston, engineers simulated conditions that astronauts in space suits would experience when the Orion spacecraft is vibrating during launch atop the agency’s powerful Space Launch System rocket on its way to deep space destinations.

A series of tests occurring this month at Johnson will help human factors engineers assess how well the crew can interact with the displays and controls they will use to monitor Orion’s systems and operate the spacecraft when necessary.

NASA Simulates Orion Spacecraft Launch Conditions for Crew

Test subjects wore modified advanced crew escape suits that are being developed for astronauts in Orion, and sat in the latest design of the seat atop the crew impact attenuation system.

This was the first time this key hardware was brought together to evaluate how launch vibrations may impact the astronaut’s ability to view the displays and controls. While Orion’s late 2018 mission will be uncrewed, engineers are hard at work performing all the necessary evaluations to make sure the spacecraft is ready for crewed missions beginning as early as 2021.

The Space Launch System’s core stage engine section structural qualification test article is stacked and prepared for shipment on the barge Pegasus from NASA’s Michoud Assembly Facility in New Orleans to NASA’s Marshall Space Flight Center in Huntsville, Alabama where it will be structurally tested.

This marks the first delivery of a major SLS vehicle element manufactured at Michoud. The rocket’s engine section is the bottom of the core stage where the four RS-25 engines are attached. The engine section test article minus engines was vertically stacked with hardware on top that simulates part of the rocket’s liquid hydrogen tank that joins to the engine section at the bottom of the 212-foot-tall SLS core stage.

The Pegasus barge also will transport the entire flight core stage to NASA’s Stennis Space Center near Bay St. Louis, Mississippi, for testing and then on to NASA’s Kennedy Space Center in Florida for integration into the SLS vehicle and launch
