Q&A with Elon Musk, SpaceX’s founder and CEO

A Cargo Dragon spacecraft launched to begin its fifth journey to the International Space Station, carrying with it more than 6,000 pounds of science and supplies. Liftoff happened at 9:29 p.m. EST Monday (0229 UTC Tuesday).

Viasat announced Thursday that a SpaceX Falcon Heavy rocket will launch a next-generation broadband satellite from pad 39A at the Kennedy Space Center some time between 2020 and 2022, joining Arianespace and United Launch Alliance in a three-way split for Viasat’s new launch contracts.

SpaceX test-fired the Falcon 9 rocket early Saturday ahead of launch with the next four astronauts heading to the International Space Station. The static fire test before sunrise Saturday in Florida was a major step toward liftoff Thursday.
