Video: Expedition 49 crew launches to the International Space Station

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.

Concerns over an unspecified part flying on the upper stages of United Launch Alliance’s rockets have delayed the launch of a GPS satellite on a Delta 4 booster from July 25 to no earlier than Aug. 22. The same issue has also delayed an Atlas 5 launch.

An optical reconnaissance satellite for the French military took off atop a Soyuz launcher Tuesday, riding the Russian-made rocket from a tropical spaceport in South America into a 300-mile-high polar orbit to begin a 10-year mission surveying the globe.
