AA-2 Teams Rehearse for Test of Launch Abort System

On Monday, June 3 and Saturday, June 8, NASA launch teams, in coordination with U.S. Air Force and industry teams, held the first two of three dress rehearsals for the Ascent Abort-2 (AA-2) flight test at Hangar AE at Cape Canaveral Air Force Station in Florida. AA-2 will demonstrate the Launch Abort System (LAS) can quickly get astronauts safely away from the rocket in the event of a problem during launch.

During the daylong rehearsals, launch team managers simulated several countdowns, including a number of challenges for different team members to overcome. In one simulation, there was a lightning strike four miles from the pad. In another scenario, the launch director had to leave his station due to an illness, forcing his backup to immediately step in and take over the lead role.

The LAS is located at the very top of the rocket and has three motors working together to pull Orion away from the Space Launch System — NASA’s next generation rocket. Once activated, the LAS can steer the spacecraft and carry astronauts to a safe distance if an emergency arises during Orion’s climb to orbit.

Orion is designed to transport astronauts safely on deep space missions as NASA works to land the first woman and next man on the Moon by 2024.
