Live coverage: Two satellites lift off aboard Ariane 5

The French government has signaled its intention to sell its stake in Arianespace, a major step in consolidating the European launcher industry under the control of a joint venture formed by Airbus and rocket engine manufacturer Safran.

A European environmental satellite rode a solid-fueled Vega launcher from a tropical spaceport at the edge of the Amazon jungle into polar orbit Monday night, adding a new eye in the sky to check on the health of crops and forests from space.

A $66 million NASA-funded science sensor package bolted on to a commercial communications satellite is ready for a ride toward a 22,000-mile-high orbital perch Thursday on a European Ariane 5 rocket, commencing a two-year mission surveying a rarely-studied region of Earth’s upper atmosphere.
