This market will resolve to "Yes" if the Boeing Starliner spacecraft departs the International Space Station (ISS) with NASA astronauts Suni Williams and Butch Wilmore by 11:59 PM ET on July 4, 2024.

The Starliner will be considered to have departed if it has undocked from the ISS and begun its return journey to Earth.

The resolution source will be official announcements from NASA and/or Boeing, however a consensus of credible reporting from major news outlets such as CNN, BBC, or Reuters may also be used.
