Watch live as ULA’s Atlas V rocket lifts off from Cape Canaveral with the USSF-7 mission for the U.S. Space Force and U.S. Air Force.
USSF-7 mission’s primary payload is a mystery robotic X-37B Space Plane, also known as the Orbital Test Vehicle.
The launch is planned for May 17 at 13:14 UTC.
The U.S. Air Force and Space Force have two reusable X-37B space planes, both built by Boeing, for classified missions in low-Earth orbit that can last years.
