Q&A with Dan Hart, president and CEO of Virgin Orbit (members only)

A United Launch Alliance Delta 4-Heavy rocket stands 233 feet tall at Space Launch Complex-6 at Vandenberg Air Force Base, California, ready for liftoff Saturday night carrying a top secret U.S. government spy satellite into orbit.

South Korea’s Anasis 2 military communications satellite, built in Europe by Airbus, lifted off Monday from pad 40 at Cape Canaveral Air Force Station on top of a SpaceX Falcon 9 rocket. Launch occurred at 5:30 p.m. EDT (2130 GMT).

A month-and-a-half after a general strike in French Guiana halted launch preparations, an Ariane 5 rocket arrived at its launch pad Wednesday on the northeastern coast of South America, a day before hauling two communications satellites into orbit for the Brazilian government and a South Korean company.
