iss059e087869 (June 3, 2019) --- NASA astronaut Christina Koch poses for a portrait inside of the vestibule between the SpaceX Dragon cargo craft and the Harmony module. The hatch to Dragon was later closed and the resupply ship detached from Harmony before it was released from the grips of the Canadarm2 robotic arm. Dragon spent nearly a month attached to the International Space Station.
