This is a market on which launch will be successfully completed first: NASA's Artemis or SpaceX's Starship.

If NASA's Artemis completes a successful launch before SpaceX's Starship, this market will resolve to "Artemis". If SpaceX's Starship completes a successful launch before NASA's Artemis, this market will resolve to "Starship".

This market may resolve as soon as one of the mentioned launches is successfully completed.

If neither launch is successfully completed by December 31, 2023, 11:59:59 PM ET, this market will resolve to 50-50.

A successful launch will mean that either mission takes off from its launchpad and successfully reaches the Karman Line, an altitude of at least 100 Kilometers (~62 miles) above sea level.

The primary resolution source for this market will be official information from NASA, or SpaceX, and/or the official video feed of the launched missions (e.g. https://www.youtube.com/c/NASA, https://www.youtube.com/c/SpaceX), however secondary video feeds and other credible reporting may also be used.

Any subsequent anomaly (e.g. an explosion, deorbiting, etc.) after the core stage of either mission reaches the Karman Line will have no bearing on the resolution of this market.
