After delays reported June 13, a first test of Northrop's Manned Launch Abort System (MLAS) was reported to have been a success. NASA conducted the unpiloted MLAS test July 8 at Wallops Island.
Unlike the Orion escape system - which has a single launch abort motor in a tower positioned above the Orion Crew Module, the MLAS concept would have four or more rocket motors attached inside a bullet-shaped composite fairing.
Both systems are designed to propel the crew module and fairing from an Ares I rocket in the event of a launch emergency.
