A United Launch Atlas 5 rocket is set to loft three military satellites for the U.S. Air Force on a mission codenamed AFSPC 11. This timeline shows the major mission events planned over a six-hour flight to a near-geostationary orbit.

SpaceX’s first Crew Dragon spacecraft, a capsule designed to eventually carry astronauts on treks to the International Space Station, has arrived at Cape Canaveral to begin preparations for launch on an unpiloted test flight later this year.

SpaceX and United Launch Alliance have split up to $645 million in new contracts to deploy U.S. Air Force navigation and surveillance satellites into orbit from 2019 through 2021.
