A fully functional launch abort system (LAS) with a test version of the Orion crew spacecraft attached soars upward on NASA’s Ascent Abort-2 (AA-2) flight test atop a Northrop Grumman provided booster on July 2, 2019, after launching at 7 a.m. EDT, from Launch Pad 46 at Cape Canaveral Air Force Station in Florida.
During AA-2, the booster sent the LAS and Orion to an altitude of 31,000 feet, traveling at Mach 1.15 (more than 1,000 mph). The LAS’ three motors will work together to pull the crew module away from the booster and prepare it for splashdown in the Atlantic Ocean. The flight test will prove that the abort system can pull crew to safety in the unlikely event of an emergency during ascent.
