Patrick Shea inspects a 1.3 percent scale model of SLS in a wind tunnel at NASA’s Ames Research Center in Silicon Valley, California, in 2016. The tests were designed to determine the powerful rocket’s behavior as it climbs and accelerates through the sound barrier after launch. To also test a new optical-measurement method, Ames engineers coated the SLS model with unsteady pressure-sensitive paint, which, under the lighting, glows dimmer or brighter according to the air pressure acting on different areas of the rocket.

The Orion crew module undergoes a direct-field acoustic test, where stacks of more than 1,500 speakers were used to expose the spacecraft to the maximum acoustic levels that it will experience at launch. Spacecraft response and sound-pressure data were collected with microphones, strain gauges, and accelerometers.

A fully functional Launch Abort System with a test version of Orion attached, soars upward on NASA’s Ascent Abort-2 flight test on July 2, 2019, at Cape Canaveral Air Force Station, in Florida. The LAS’s three motors will work together to pull the crew module away from the booster and prepare it for splashdown in the Atlantic Ocean in the unlikely event of an emergency during ascent.
