Hauling nearly three tons of supplies, hardware and experiments, a SpaceX Falcon 9 rocket shot into orbit Monday from Cape Canaveral, with a previously-flown Dragon cargo carrier riding a reused first stage booster to kick off a nearly two-day journey to the International Space Station.

Mike Laidley leads development of Orbital ATK’s Next Generation Launch system, a rocket the commercial space company hopes will provide a foothold in the lucrative market to launch U.S. military satellites, a business currently dominated by SpaceX and United Launch Alliance.

Closing out 52 days at the International Space Station, an automated Northrop Grumman Cygnus cargo craft left the research outpost Sunday to climb into a higher orbit for deployment of six CubeSats and further engineering experiments, before de-orbiting over Pacific Ocean later this month.
