Photos: More shots of Saturday’s Delta 4-Heavy rocket Launch

SpaceX’s second Falcon Heavy rocket is set for liftoff Thursday from NASA’s Kennedy Space Center in Florida, and the heavy-lift launcher will head on an easterly course over the Atlantic Ocean atop more than 5 million pounds of thrust.

Rocket Lab’s light-class Electron launcher is set to take off on its seventh flight from New Zealand, aiming for a 280-mile-high (450-kilometer) orbit with seven small satellites for commercial customers, the U.S. military and university students.

The European Space Agency’s $550 million Aeolus science mission, the product of a drawn-out 16-year development effort that required engineers to master new technologies, is in the starting blocks on a launch pad in French Guiana awaiting liftoff Wednesday to monitor wind speeds from space for the first time on a global scale.
