They won’t. 🚀 @NASA’s @SpaceX Crew‑13, Commander Jessica Watkins, Pilot Luke Delaney, Canadian Space Agency's Joshua Kutryk, and Roscosmos’ Sergey Teteryatnikov, signed the hatch on a mock‑up of their Dragon spacecraft during mission training. The hatch‑signing ceremony is a time‑honored astronaut tradition symbolizing crew unity and readiness before their launch to the International @Space_Station, scheduled no earlier than September 12.
