Lockheed Martin will build two communications satellites for Saudi Arabia’s Arabsat, and Arianespace and SpaceX will launch the commercial relay platforms under contracts valued at $650 million announced Wednesday.

United Launch Alliance’s Atlas 5 rocket made its way back to the pad at Space Launch Complex 41 at Cape Canaveral Space Force Station on Thursday morning for a mission carrying national security mission payloads, collectively codenamed Silentbarker. Liftoff has been rescheduled for at 8:47 a.m. EDT (1247 UTC).

SpaceX’s two fast-maneuvering payload fairing recovery vessels were in the right place at the right time Monday to catch both halves of the nose shroud jettisoned by a Falcon 9 rocket climbing into orbit with South Korea’s Anasis 2 military communications satellite.
