A Rocket Lab Electron rocket launched NASA’s Starling mission, which consists of four cubsats to demonstrate technologies for future ‘swarm’ satellites. It will also carry Telesat’s LEO 3 demonstration satellite for Space Flight Laboratory and two 3U satellites for Spire Global, carrying Global Navigation Satellite System Radio Occultation (GNSS-RO) payloads which provide data to improve weather models and forecasts. The first stage of the Electron rocket was recovered after it splashes down in the ocean. Delayed from July 14.
