NASA’s Artemis II—the first mission to carry humans beyond low Earth orbit in more than 50 years—is scheduled to launch on April 1, 2026. The 10-day journey will take four astronauts around the moon and back, testing NASA’s new launch system before future missions to the lunar surface.

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.

Spacecraft response and sound-pressure data were collected with microphones, strain gauges, and accelerometers.

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.
