This market resolves YES if the second stage of SpaceX's 9th full stack launch of Starship successfully reaches its intended orbital or near-orbital trajectory; reenters mostly in one piece, performs it's flip manoeuver, and reduces its velocity enough that I'd consider it a soft touchdown (an explosion upon contact with the ocean would not necessarily disqualify it so long as it is slow enough and controlled)

Otherwise if the ship fails at any earlier point in flight, or collides with the ocean at significant speed or at a notable angle, this market will resolve NO

The market will resolve N/A if a soft touchdown on the ocean isn't targeted, or otherwise if the intended flight profile is sufficiently different from expected such that this market no longer applies

I won't participate in case resolution is ambiguous

I will likely choose to close the market just before launch to recoup some mana spent on creation
