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.

Rollout of the Atlas 5 rocket from the Vertical Integration Facility to the launch pad at Complex 41 occurred at 10 a.m. on Monday. Liftoff is planned for Tuesday night to deliver the Cygnus resupply ship into orbit en route to the International Space Station.

This is the launch timeline to be followed by the Atlas 5 rocket’s ascent into orbit from Cape Canaveral with the commercial Orbital ATK Cygnus cargo freighter headed to the International Space Station. Launch is scheduled for Tuesday at 11:11 a.m. EDT (1511 GMT).
