Video: Falcon 9 launch with natural sound (members only)

Flying for the 155th and final time, a United Launch Alliance Delta 2 rocket took off from California on Sept. 15 with NASA’s ICESat 2 satellite.

Powering off the planet just after sunset Friday, a SpaceX Falcon 9 rocket took off from Cape Canaveral with the multi-mission SES 9 communications satellite to link millions of homes, businesses, ships and airplanes across the Asia-Pacific.

SpaceX released a video Thursday showing a propulsive hover test of a prototype of the company’s Dragon crew capsule conducted two months ago, a milestone in the development of the spaceship’s rocket packs that will eventually guide the craft to helicopter-like landings.
