Executive takeaway

Soyuz MS‑28 continued the long‑standing US‑Russia crew‑exchange partnership on the International Space Station, underscoring diplomatic cooperation in human spaceflight despite broader geopolitical tensions.

Its successful rapid two‑orbit rendezvous supports the operational tempo required for continuous habitation of the station.
