When it does, the abortion engine will start up and pull the module away from the booster, while the attitude control monitor will be in charge or steering into position so it can be jettisoned back to Earth. The whole process will only take three minutes, but NASA is bound to spend more time than that crunching the data it collects from the capsule's 900 sensors, including microphones and temperature and pressure instruments.
Mark Kirasich, Orion's program manager, explained:
"This test is extremely important. Our Launch Abort System is a key safety feature of the spacecraft ̵1; it will protect the crew members who fly onboard Orion during the most challenging part of the mission, which is the ascent phase. "
The test's launch window will begin at 7AM ET and will last for four hours until 11AM. NASA will start its coverage of the event at 6:40 AM ET, and you can watch it all go down on the agency's website or through the video embedded below.
On July 2nd, Ascent Abort-2 flight test will demonstrate @NASA_Orion 's safety system to carry @NASA_Astronauts to the Moon and on to Mars! Live coverage starts at 6:40 am EST. https://t.co/X4dPRAFWOQ pic.twitter.com/yoVSCbooBl
