SpaceX [Space Exploration Technologies Corporation] has successfully tested an astronaut escape system to carry out astronauts safely in a life-threatening situation on the launch pad.
During the test, the Crew Dragon spacecraft fired its eight SuperDraco engines for about six seconds which produced about 15,000 pounds of thrust each and lifting the spacecraft out over the Atlantic Ocean before jettisoning its trunk, as planned and parachuting safely into the ocean.
The test lasted about two minutes from engine ignition to splashdown.
During the test, Crew Dragon carried a test dummy equipped with sensors in order to gather all the data necessary to help ensure a safe environment for astronauts.
The test was the first with a full-size developmental spacecraft using a complete set of eight SuperDraco engines to create a real-world conditions of a pad abort situation.
