Live coverage: Japan’s H-2A rocket blasts off on first commercial flight

After completing a dress rehearsal for launch day over the weekend, the four astronauts gearing up for liftoff Thursday on a SpaceX Falcon 9 rocket are in good spirits and spending time with their families in Florida before leaving the planet for a six-month expedition on the International Space Station. Forecasters with the U.S. Space Force’s 45th Weather Squadron predict an 80% chance of acceptable weather for launch early Thursday.

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.

Four satellites fastened to the top of an Ariane 5 rocket will grow Europe’s space-based Galileo navigation network Thursday morning with a launch from the South American jungle.
