Live coverage: Vega rocket launches with LISA Pathfinder

Europe’s ExoMars rover will not be ready for launch in 2018, officials said Monday, forcing a two-year delay for the ambitious mission to drill into the Martian surface and search for the remnants of past life.

Europe’s solid-fueled Vega booster vaulted away from a launch pad in the South American jungle late Thursday and deftly delivered five sharp-eyed Earth observation satellites into two different orbits for the Peruvian government and a Google-owned mapping company.

Arianespace officials have approved the rollout and launch of the final Ariane 5 flight of the year, set to blast off Wednesday from French Guiana to haul Brazilian and Japanese communications stations toward their orbital perches more than 22,000 miles above the equator.
