Live coverage: Orion lands in Pacific

After being put back in position around the Delta 4-Heavy rocket after Thursday’s weather scrub, the 330-foot tall mobile service tower is retracted again at Cape Canaveral’s pad 37B for launch that will place the NROL-37 payload into Earth orbit.

Two communications payloads — one for Intelsat and another for Europe’s data relay satellite system — lifted off from French Guiana aboard an Ariane 5 rocket at 1930 GMT (3:30 p.m. EDT) Tuesday.

Ten new satellites joined Iridium’s global voice and data relay constellation Sunday after a successful launch, and landing, of a SpaceX Falcon 9 rocket from Vandenberg Air Force Base in California. Liftoff occurred at 1:25 p.m. PDT (4:25 p.m. EDT; 2025 GMT).
