Houston Launch Control This is Mission Control Houston. Kennedy Launch Control Discovery roll program. Lee Archambault/STS-119 Commander Roger roll Discovery. Houston Launch Control Discovery's roll maneuver is complete. It is now in a heads-down position on track for its flight to the International Space Station. Discovery flying 365 mph, 1 1/2 miles in altitude, seven miles downrange from the Kennedy Space Center. Discovery's engines are throttling down as the orbiter passes through the area of maximum pressure on the vehicle. Kennedy Launch Control Discovery go at throttle up. Lee Archambault/STS-119 Commander Discovery go at throttle up. Houston Launch Control Three main engines on board are throttling back up. Now one minute, 12 seconds into the flight, Discovery flying at 1,800 mph, 10 miles in altitude and 11 1/2 miles downrange from the Kennedy Space Center. At liftoff the fully fueled shuttle boosters and external tank weighed 4 1/2 million pounds. The total thrust at launch was 6,425,000 pounds. All systems continue to function well. Three good main engines, three good power-generating fuel cells and three good auxiliary power units for the hydraulic system. We will now standby for burnout and separation of the solid rocket boosters. Combined, the twin boosters provide 5.3 million pounds of thrust to propel the orbiter toward space. Discovery now flying 3,600 mph, 32 miles in altitude, 43 miles downrange from the Kennedy Space Center (less)
