NASA fired up four hydrogen-fueled main engines on the core stage of the first Space Launch System heavy-lift rocket Thursday in on a test stand in Mississippi, a redo of a crucial hot fire test that was cut short in January by technical issues. The engines burned more than eight minutes in an apparently successful test.

As viewed from the ITL Causeway at the Cape Canaveral Air Force Station, the United Launch Alliance Atlas 5 rocket departs for space with the EchoStar 19 satellite to delivery Internet connectivity across the U.S.

Succeeding on a one-shot launch attempt before Hurricane Irma shuts down the Cape Canaveral spaceport, a SpaceX Falcon 9 rocket thundered into orbit Thursday with the U.S. Air Force’s X-37B spaceplane, a reusable robotic mini-shuttle that could stay aloft for years with clandestine on-board experiments.
