Throttle-up and Separation To get his crews, and the payloads which will follow into low Earth orbit, Robert L Carter, NASA's Head of Operations and Administration has devised a totally new means of boosting his spacecraft into low Earth orbit. Called the "Inertia Method" Crater has theorised that by creating boosters with a variable thrust capacity he can use this method to quite literally sling-shot his human and cargo payloads into space. It is a method now about to be tested for the first time. Using readings relayed by the spacecraft to Mission Control Carter knows when the ARES 1 booster is 90 seconds away from fuel depletion and engine shut-down. When this exact moment arrives Carter's people send a signal which throttle's-up the booster to 110% thrust whilst at exactly the same moment firing a series of explosive bolts which will allow the CRC to separate from its booster. As the engine on the ARES 1 splutters and dies from lack of fuel, the CRC now free of the heavy booster separates and hurtles onward toward low Earth orbit.
