Live coverage: Two satellites lift off aboard Ariane 5

A powerful European Ariane 5 rocket blasted off from French Guiana late Friday and boosted a pair of satellites into space for a seven-year plunge into the inner solar system, a voyage requiring seven planetary flybys to slow down enough in the sun’s gravitational clutches to slip into orbit around hellish Mercury.

Arianespace delayed the launch of a Vega rocket from French Guiana Tuesday night due to a typhoon threatening a ground station in South Korea needed to track the vehicle as it deploys a cluster of more than 50 small satellites.

The Italian government has decided to launch two next-generation radar reconnaissance satellites on Soyuz and Vega rockets from French Guiana, and a European Space Agency telescope to study the structures of planets around other stars will likely ride to orbit as a co-passenger on one of the missions.
