Live coverage: NASA completes eight-minute Space Launch System hot fire test

Maintaining a brisk flight rate three days after its last launch, SpaceX sent a Falcon 9 booster powered by a reused first stage into orbit Wednesday evening from Florida with an Airbus-built communications satellite for SES and EchoStar.

Rocket Lab’s light-class Electron launcher is set to take off on its fourth flight from New Zealand, aiming to deliver 13 CubeSats to orbit on the company’s first mission for NASA.

Assuming a May 1 launch, the Starliner spacecraft would dock with the ISS on May 2. The spacecraft will launch on the 100th flight of United Launch Alliance’s Atlas 5 rocket.
