A month-and-a-half after a general strike in French Guiana halted launch preparations, an Ariane 5 rocket arrived at its launch pad Wednesday on the northeastern coast of South America, a day before hauling two communications satellites into orbit for the Brazilian government and a South Korean company.

SpaceX teams at Cape Canaveral are readying for the company’s 10th Falcon 9 rocket launch of the year Wednesday, another flight devoted to delivering satellites to orbit for the Starlink internet network.
