Photos: Atlas 5 powers away with NROL-61 payload

Seven small satellites rode a Rocket Lab Electron rocket into orbit Saturday from New Zealand. Carrying commercial, military and student payloads, the Electron launcher lifted off at 0430 GMT (12:30 a.m. EDT).

In this time-lapse video, a Falcon Heavy rocket is lifted into position atop launch pad 39A at the Kennedy Space Center in readiness for a pre-flight test firing of its 27 Merlin main engines.

The launch of a Japanese H-2B rocket was called off Tuesday after a fire broke out on the launch pad a few hours before liftoff. A new target launch date has not been confirmed. The mission will carry an HTV cargo ship into orbit on a resupply run to the International Space Station.
