Progress 64P: Full launch broadcast

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.

The next flight of China’s heavy-lift Long March 5 rocket will debut a new configuration designed to launch modules for a Chinese space station. But a demonstration launch of the Long March 5B booster scheduled as soon as April will instead carry a prototype of China’s next-generation deep space crew capsule into orbit on an unpiloted test flight.
