Three Chinese military surveillance spacecraft and an experimental nanosatellite rode a Long March 4C rocket into orbit Tuesday.

Viasat announced Thursday that a SpaceX Falcon Heavy rocket will launch a next-generation broadband satellite from pad 39A at the Kennedy Space Center some time between 2020 and 2022, joining Arianespace and United Launch Alliance in a three-way split for Viasat’s new launch contracts.

United Launch Alliance will need to lure commercial customers to ensure the economic viability of its new Vulcan rocket, which is set to debut in 2019 just as the rate of U.S. military satellite launches is due to take a dip.
