This market will resolve to “Yes” if two SpaceX Starships successfully execute a docking maneuver in a stable Earth orbit between market creation and the listed date, 11:59 PM ET. Otherwise, this market will resolve to “No”.

A qualifying docking maneuver must physically join two vessels, matching in velocity, into a connected structure via mating hardware for at least 60 continuous seconds. The two vessels must be in stable Earth orbit with a perigee of at least 100 kilometers above the Earth’s surface.

The two vessels must be free-flying. Any capsule or payload carried to orbit exclusively atop a separate launch vehicle will not qualify. If either vessel is passively placed into the mating interface of the other vessel, that conjunction will not qualify.
