Live coverage: Vega rocket launches with LISA Pathfinder

An Ariane 5 rocket journeyed from its assembly hangar to a nearby launch pad in French Guiana on Tuesday, a day before the heavy-duty launcher is scheduled for liftoff with the first in a new generation of high-capacity communications satellites for Intelsat.

A Vega rocket faltered minutes after liftoff from French Guiana at 9:53 p.m. EDT Wednesday (0153 GMT) and failed to reach orbit with a European-built reconnaissance satellite for the United Arab Emirates. The payload and launcher fell into the Atlantic Ocean, marking the first failure for the solid-fueled Vega launch vehicle.

A new flyby mission selected by the European Space Agency this week for launch in 2028 will be the first to intercept a new comet or interstellar object fresh from the frozen depths of the outer solar system, or beyond.
