Juno Launches to Jupiter

George Diller/Launch Commentator: T minus 10… nine… eight… seven… six… five… four… three… two… one… ignition and liftoff of the Atlas V with Juno on a trek to Jupiter, a planetary piece of the puzzle on the beginning of our solar system.

Marty Malinowski/Ascent Commentator: Pitch and yaw roll program is in progress. Vehicle flight rates look good. Booster PU has gone (inaudible) short burn. SRB chamber pressures have plateaued. Now reporting all signatures look good. RD-180 operation is excellent at this point in the flight.


Marty Malinowski/Ascent Commentator: Mach 1. SRB chambers continue to roll off. Max Q. Boosters throttling up right on schedule, engine response looks good. Boost PU has gone on closed loop control. Looking for our SRB throttle down momentarily. Engine continues to operate well. And booster has throttled back. Looking for SRB burnout soon. Chamber pressures have plateaued on the SRBs. And beginning to roll off. And BECO has been satisfied. Vehicle is throttling back up to full thrust. And we have solids 1, 2, 3, 4, and 5 jettison. Visual indication that all solids have separated well.
