NASA’s Max Launch Abort System Test from PopSci.com on Vimeo.
This is a test of a proposed escape system for the Orion Spaceship. Oriion will be the next manned system to replace the Shuttle if it survives budget cuts. The Orion design currently has an escape rocket similar to the Apollo system. MLAS is an alternative answer. Testing of MLAS will continue because it’s a separate budget item for NASA. Whether or not Orion goes forward, MLAS will probably be seen on future spacecraft.
