A busy slate of launches was planned for the last full week of September, including flights for two major low-Earth orbit broadband constellations, as well as a NASA science mission that has now flown. China and Rocket Lab were also planning flights, with Electron set to fly two suborbital hypersonic research missions from Wallops Island, Virginia. One has flown and the other was pushed into the following launch week.
The United Launch Alliance (ULA) flew an Atlas V 551 on the KA-03 mission for the Amazon Kuiper constellation, while SpaceX ended up flying three Falcon 9 Starlink missions.
