This question revolves around whether SpaceX's Starship will complete orbit in 2023, with a resolution criterion of at least one orbital spaceflight. The definition of orbit is based on a trajectory that allows for remaining in space for at least one full circle. A determination on this will be made by Scott Alexander, who has consulted experts on the matter and aims to generally adhere to this definition. The outcome will have no bearing on other predictions or evaluations on other platforms, such as Metaculus. The contest rules and full list of questions are available for further information.
