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.

Arianespace’s launch team in French Guiana rolled an Ariane 5 booster to its launch pad Tuesday and readied the rocket for liftoff Wednesday with an Inmarsat satellite to connect airline passengers over Europe and an Indian communications craft.

A SpaceX Falcon 9 rocket lifted off from Vandenberg Air Force Base in California at 10:34 a.m. PST (1:34 p.m. EST; 1834 GMT) Monday. The launch, under contract to Spaceflight, carried into orbit 64 small satellites from 17 countries, the largest multi-payload rideshare mission ever flown on a U.S. rocket. The Falcon 9’s first stage booster previously flew on two missions from Florida, and landed again on a drone ship in the Pacific Ocean after Monday’s launch.
