Live coverage: Two satellites lift off aboard Ariane 5

A Japanese H-2A rocket lifted off from the Tanegashima Space Center at 0017:46 GMT Thursday (8:17:46 p.m. EDT Wednesday) with the Michibiki 2 navigation satellite designed to improve positioning and timing services over Japan.

A Russian-made Soyuz booster rolled out to its launch pad in French Guiana on Friday, and hydraulic lifts rotated the launcher vertical in preparation for liftoff Tuesday with the first in a new series of French military spy satellites.

Europe’s next-generation launcher family has moved a step closer to reality with the signature of nearly $3.8 billion in contracts for development of the Ariane 6 rocket and an upgraded version of the lightweight Vega booster.
