Video: Atlas 5 rocket launches space station cargo mission

United Launch Alliance, the incumbent leader in U.S. rocketry, goes for its 100th flight Friday, a milestone nine years in the making after eclectic missions to Mars, the moon and Jupiter, and deployments of commercial, military and reconnaissance spacecraft.

Most parts of the joint European-Russian ExoMars lander and rover are nearly ready for launch, but trouble with parachutes, electronics, software and concerns about the growing coronavirus pandemic have delayed the mission’s departure to Mars from this year until 2022, officials announced Thursday. 

A Turkish-owned communications satellite is set to rocket into orbit Thursday night from Cape Canaveral to open SpaceX’s 2021 launch schedule.
