Rocket Lab’s next launch from New Zealand, set for Friday, will carry a data recorder to measure the aerothermal environments encountered by the Electron launcher’s first stage during descent back into the atmosphere, information engineers say is crucial to successfully achieving the company’s newly-announced plan to recover and reuse the booster.

Virgin Orbit could attempt its first orbital test launch later this month over the Pacific Ocean southwest of Los Angeles, capping a development program for an air-launched small satellite carrier that began in earnest eight years ago.

The flight of a United Launch Alliance Delta 4-Heavy rocket set for Aug. 26 from Cape Canaveral continues the Delta rocket family’s countdown to retirement. With five Delta 4-Heavy missions left to launch, ULA’s chief executive Tory Bruno says there are no plans to build more as the company transitions to the next-generation Vulcan Centaur rocket.
