Photos: Predawn launch of Atlas 5

An Airbus-owned, German-built outdoor science deck is set for launch Friday night from Cape Canaveral aboard a SpaceX Dragon cargo capsule, heading for the International Space Station to make the orbiting research outpost more accessible for commercial space experiments.

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.

The United Launch Alliance Atlas 5 rocket and NASA’s four MMS satellite probes passed their Flight Readiness Review on Friday that assessed the progress of work and affirmed plans to launch next Thursday night.
