Mark Kelly/STS-134 Commander: Houston, Endeavour, roll program.
Barry Wilmore/STS-134 CAPCOM: Roger, roll Endeavour.
Kyle Herring/STS-134 Ascent Commentator: Houston is now controlling. Endeavour beginning to rollover onto its back. The roll program out of the way as Endeavour begins the heads-down position on course for a 56.1-degree, 136-by-36-statue-mile orbit.
Three engines now throttling down as Endeavour passes through the area of maximum dynamic pressure on the vehicle in the lower atmosphere. Approaching one minute into the flight.
Barry Wilmore/STS-134 CAPCOM: Endeavour "go" at throttle up.
Mark Kelly/STS-134 Commander: Roger, "go" at throttle up.
Kyle Herring/ STS-134 Ascent Commentator: Endeavour's three main engines now back at full throttle. All three engines in good shape. Endeavour’s already traveling 1,300 mph, at an altitude of 11 miles downrange from the Kennedy Space Center, now 12 miles.
At liftoff, Endeavour fully fueled weighed four and a half million pounds. It's already lost half that weight in propellent now burned that weight. Next event is burnout and separation of the twin solid rocket boosters. That upcoming here shortly at the two-minute, three-second point. Those boosters are burning 11,000 pounds of fuel per second.
And standing by for separation of the solid rocket boosters.
