Photos: Atlas 5 rocket aims for International Space Station

SpaceX’s Falcon 9 rocket is set for liftoff from Cape Canaveral on Tuesday, heading due east over the Atlantic Ocean to deliver the Hispasat 30W-6 communications satellite into orbit around 33 minutes later.

The mission will be the 14th time that a SpaceX Dragon spacecraft carries humans to the International Space Station. The mission launched on Friday, March 14, at 7:03 p.m. EDT (2303 UTC).

After completing a dress rehearsal for launch day over the weekend, the four astronauts gearing up for liftoff Thursday on a SpaceX Falcon 9 rocket are in good spirits and spending time with their families in Florida before leaving the planet for a six-month expedition on the International Space Station. Forecasters with the U.S. Space Force’s 45th Weather Squadron predict an 80% chance of acceptable weather for launch early Thursday.
