Snapshots from Atlas 5 launch

The Pentagon has awarded at least $162 million in contracts to Aerojet Rocketdyne and United Launch Alliance for development of the AR1 and BE-4 rocket engines, candidates to power the first stage of a next-generation rocket and replace the Russian-made engine currently flying on the Atlas 5 launcher.

Fully fueled for a flight to the International Space Station later this month, SpaceX transferred the Crew Dragon “Resilience” spaceship Thursday to a hangar near pad 39A at the Kennedy Space Center for attachment to its Falcon 9 launcher.

The launch of a NASA ionospheric research satellite off Florida’s east coast is targeted for Oct. 9 after persistent technical problems with its air-dropped Pegasus rocket stymied two launch opportunities last year.
