Live coverage: Ariane 5 rocket deploys satellites for Australia, India

SpaceX’s next launch with a European-built communications satellite has been delayed to no earlier than March 28 to study a problem with a helium pressurization system on the Falcon 9 rocket, officials said Tuesday.

China’s second Long March 5 rocket fell short of orbit Sunday after lifting off from a spaceport in the southern Chinese province of Hainan, placing a cloud over the country’s plans to send a robotic sample return mission to the moon later this year.

The third Ariane 5 flight of the year is on track for a late afternoon liftoff Thursday from French Guiana with two U.S.-built communications satellites to broadcast television channels to millions of DISH Network subscribers and improve banking services across the islands of Indonesia.
