Here's a good overview of the mission: Saturday's mission will begin with ignition of the Atlas Common Core Booster's RD-180 engine, 2.7 seconds before the countdown reaches zero... Five Aerojet Rocketdyne AJ-60A solid rocket motors will augment the CCB at liftoff, igniting about T+1.1 seconds as the rocket lifts off. Climbing away from Cape Canaveral, AV-079 will begin a series of pitch and yaw maneuvers 3.9 seconds into its mission, placing the rocket onto an 89.9-degree azimuth -- almost due East -- for the journey into orbit. Atlas will reach Mach 1, the speed of sound, 34.4 seconds after liftoff, passing through the area of maximum dynamic pressure -- Max-Q -- eleven-and-a-half seconds later.
Long-time Slashdot reader Zorro also shares an interesting remark by the CEO of Boeing when asked if Boeing's cancelled Sonic Cruiser might be making a comeback. "'Something better,' teased the Boeing boss, promising point-to-point connectivity anywhere on Earth in a matter of hours."
And when asked whether Boeing might launch a car into space, he replied instead that "We might pick up the one that's out there and bring it back."
