Traffic at the International Space Station (ISS) is busy, with spacecraft coming and going almost every few weeks recently. Astronauts with the private Ax-4 mission undocked early July 14 to make way for SpaceX's upcoming Crew-11 mission for NASA, a SpaceX Cargo Dragon left the station at the end of May, and a Russian Progress cargo spacecraft arrived July 5, with its predecessor set to depart next month.
By the end of the year, nearly a half-dozen other spacecraft will launch to the ISS, delivering crew, cargo, research and technology demonstrations. It's one of the busiest eras the orbital laboratory has ever experienced, as recent years, especially, have seen a high increase of activity. But absent from the mix of shuffling spacecraft, at least for the rest of 2025, is Boeing's Starliner.
