US Space Force missile-warning satellite rockets into orbit

The U.S. Space Force's newest and most advanced missile-warning satellite is in orbit

CAPE CANAVERAL, Fla. -- A $1 billion missile-warning satellite for the U.S. Space Force rocketed toward orbit Tuesday. It was the fifth in this series of space-based infrared system satellites. These advanced national security spacecraft are meant to replace the long-time Defense Support Program constellation of surveillance satellites. United Launch Alliance sent the Atlas V rocket skyward from Cape Canaveral Space Force Station. “Bird away,” ULA President Tory Bruno announced via Twitter. The flight was delayed a day by a bad temperature sensor in ground equipment.
