Live coverage: China launches three-man crew to Tiangong space station

A SpaceX Falcon 9 rocket arrived at launch pad 39A on Florida’s Space Coast on Sunday, a day before liftoff with a powerhouse Inmarsat communications satellite designed to spread broadband beams connecting airline passengers, maritime crews and U.S. and international military units with Internet and data services.

SpaceX’s Falcon 9 rocket will go from Cape Canaveral to low Earth orbit in less than 10 minutes Wednesday with a Dragon capsule heading for the International Space Station carrying more than 5,600 pounds of supplies and experiments.

An air-launched rocket built by Richard Branson’s Virgin Orbit reached orbit Sunday for the first time, delivering 10 experimental CubeSats for NASA and positioning the company for the start of commercial operations.
