ATK developed the launch abort motor that sits on top of the Orion capsule. This device would pull the capsule and its crew up and away from the rocket in the event of major fault on the launch pad or during ascent. ATK also developed numerous composite parts that provide heat protection for Orion.<ref name="OrionPie">{{cite news |last=Lopez |first=Jesus |date=2 December 2014 |title=ATK test rocket one step forward to landing humans on Mars |url=http://www.standard.net/Business/2014/12/03/Test-flight-one-step-forward-to-landing-humans-on-Mars.html |newspaper=Standard Examiner |location=Ogden, Utah |access-date=January 13, 2015 |archive-date=September 24, 2015 |archive-url=https://web.archive.org/web/20150924105635/http://www.standard.net/Business/2014/12/03/Test-flight-one-step-forward-to-landing-humans-on-Mars.html |url-status=dead }}</ref>
