NASA astronaut Randy Bresnik, at left, and astronaut candidate Kayla Barron tour the Launch Abort System Facility (LASF) and visit with workers at NASA’s Kennedy Space Center in Florida on Feb. 12, 2019. Barron and Bresnik viewed the Launch Abort System (LAS) that will be used for the Orion Ascent Abort-2 (AA-2) Flight Test. AA-2 is a full-stress test of the LAS, scheduled for Spring 2019. AA-2 will launch from Space Launch Complex 46, carrying a fully functional LAS and a 22,000-pound Orion test vehicle to an altitude of 31,000 feet and traveling at more than 1,000 miles an hour. The test will verify the LAS can steer the crew module and astronauts aboard to safety in the event of an issue with the Space Launch System (SLS) rocket when the spacecraft is under the highest aerodynamic loads it will experience during a rapid climb into space. NASA's Orion and Exploration Ground Systems programs and contractors from Jacob's and Northrop Grumman in conjunction with the Air Force Space and Missile Center's Launch Operations branch are performing flight operations for AA-2.
