Photos: More Launch shots of Delta 375 rocket

A Spanish Earth observation spacecraft and a French research satellite to probe luminous phenomena above thunderstorms are packaged inside the nose cone of an Italian-built Vega rocket for launch Monday night from French Guiana.

The launch from French Guiana of a solid-fueled Vega rocket with a European-built surveillance satellite for the United Arab Emirates has been postponed, Arianespace said, citing unfavorable high-altitude winds over the spaceport. Officials have not set a new target launch date.

SpaceX performed a dramatic high-altitude test flight Sunday of the company’s Crew Dragon capsule over Florida’s Space Coast, testing the human-rated ship’s ability to escape a rocket failure and save its crew before two NASA astronauts strap in for a flight to the International Space Station as soon as this spring.
