Q&A with Tory Bruno, ULA’s chief executive

A top secret cargo for the U.S. government’s spy satellite agency soared into orbit from Cape Canaveral at the tip of a United Launch Alliance Atlas 5 rocket Friday night, successfully debuting a new solid-fueled booster design that ULA says are cheaper and easier to handle than previous strap-on motors.

The most powerful configuration of United Launch Alliance’s Atlas 5 rocket blasted off April 14 from Cape Canaveral, hauling multiple U.S. Air Force satellites to a perch high above the equator after piercing a clear evening sky over Florida’s Space Coast with 2.6 million pounds of thrust.

Towering more than 20 stories tall, the 8-million-pound mobile gantry at the Atlas 5 rocket’s launch pad at Vandenberg Air Force Base, California, was retracted into position late Friday for liftoff of NASA’s InSight mission to Mars.
