The second of three aeroshells, at right, for Orion's Launch Abort System (LAS) was lifted up from a flatbed truck and secured in High Bay 4 of the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida, on June 26, 2018. The aeroshell was shipped from EMF Inc. on nearby Merritt Island. The aeroshells will be stacked and prepared for a full-stress test of the LAS, called Ascent Abort-2 (AA-2) flight test, scheduled for April 2019. During the test, a booster will launch from Space Launch Complex 46 at Cape Canaveral Air Force Station, 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. Orion is being prepared for its first integrated uncrewed flight atop the SLS on Exploration Mission-1.
