The Boeing Pad Abort Test was an uncrewed test flight of the engines of the Boeing CST-100 Starliner that launched on 4 November 2019 from White Sands New Mexico. This was the very first flight of Starliner and one of the last milestones ahead of OFT. The mission is part of NASA's Commercial Crew Program and its objectives were to demonstrate that Starliner could safely get a crew away from the launch pad in the event of an emergency on the ground prior to liftoff. After launch, only two of three main parachutes deployed but NASA and Boeing deemed the test safe as Starliner is designed to function on two parachutes with a third parachute as a backup.

The Boeing Pad Abort Test, also known as Boe-PAT, was the first mission of the CST-100 Starliner spacecraft, conducted by Boeing as part of NASA's Commercial Crew Program. The Boeing Pad Abort Test was an uncrewed test flight of the engines of the Boeing CST-100 Starliner that launched on 4 November 2019 from White Sands New Mexico. This was the very first flight of Starliner and one of the last milestones ahead of OFT. The mission is part of NASA's Commercial Crew Program and its objectives were to demonstrate that Starliner could safely get a crew away from the launch pad in the event of an emergency on the ground prior to liftoff. After launch, only two of three main parachutes deployed but NASA and Boeing deemed the test safe as Starliner is designed to function on two parachutes with a third parachute as a backup.

History

In May 2019, all major hotfire, including simulations of low-altitude abort thruster testing, was completed using a full up service module test article that was "flight-like", meaning that the service module test rig used in the recent hotfire testing included fuel and helium tanks, reaction control system, orbital maneuvering, and attitude control thrusters, launch abort engines, and all necessary fuel lines and avionics that the ones that will be used for crewed missions will have. This clears the way for the pad abort test and the subsequent uncrewed and crewed flights later.[3] A pad abort test took place on 4 November 2019.[4] The capsule accelerated away from its pad, but then one of the three parachutes failed to deploy and the capsule landed with only two parachutes.[5]·[6] Landing was however deemed safe, and the test a success. Boeing did not expect the malfunction of one parachute to affect the Starliner development schedule.[7]
