Video: Delta 4 launches before dawn from California

SpaceX teams working at Vandenberg Air Force Base in California were finalizing preparations Tuesday ahead of the launch of a Falcon 9 rocket Wednesday carrying a trio of Canadian-built radar observation satellites into orbit.

A compact exoplanet observatory built in Europe to help astronomers determine the sizes of distant worlds around other stars is scheduled for launch Wednesday from French Guiana aboard a Soyuz rocket.

SpaceX launched a Falcon 9 rocket Thursday from Cape Canaveral with the U.S. Space Force’s newest third-generation Global Positioning System navigation satellite, helping clear the way for the launch of SpaceX’s first operational Crew Dragon astronaut mission later this month.
