Q&A with Alain Charmeau, CEO of Airbus Safran Launchers

SpaceX fired up a Falcon 9 rocket at Cape Canaveral Wednesday in a pre-flight test for a Starlink satellite launch Sunday, moving closer to the company’s final mission before sending two NASA astronauts into orbit for the first time May 27.

The Falcon Heavy rocket was lowered to the horizontal position before sunrise Friday morning after less than a day standing at the launch pad.

Engineers plan to test small modifications to a payload shroud on a European Ariane 5 rocket launch Friday from French Guiana, gathering data on changes introduced to meet stringent criteria for the launch of the $10 billion James Webb Space Telescope in late 2021.
