H0+02:19	Booster Separation
0405:23 GMT - The solid rocket boosters exhaust their propellant and are jettisoned from the Ariane 5's first stage at an altitude of about 41 miles.
H0+03:29	Jettison Payload Fairing
0406:33 GMT - The two halves of the Ariane 5's payload fairing are jettisoned once the rocket leaves the thick lower atmosphere.
H0+08:55	Main Stage Shutdown
