Snapshots from Atlas 5 launch

Hoisting a 15,000-pound satellite atop an Atlas 5 rocket Wednesday, United Launch Alliance finished assembling its next space-bound booster for liftoff Aug. 31 in support of the U.S. Navy.

Launching for the 200th time and loaded with one of its heaviest cargoes ever, the Atlas-Centaur rocket flexed its muscle and sped away from Cape Canaveral on Tuesday night with a U.S. Navy satellite for mobile communications to the military and White House.

SpaceX’s Crew Dragon Resilience spacecraft glided to a smooth automated docking Monday night at the International Space Station, delivering four astronauts to join the three-person crew already on-board, boosting the size of the lab’s long-duration crew to seven for the first time.
