Starship = the second stage, having launched on top of Super Heavy
Land = a successful landing. After it comes to rest vertically Starship should neither move, explode nor be engulfed in flames* for a period of 60 mins (if SpaceX deliberately moves the spacecraft in this hour that will obviate the no-moving requirement)
*if this is the point of contention I will make a good faith attempt to determine whether at any point in visible footage more than 25% of Starship is occluded by flames. I think this is enough to exclude minor fires.
"a" launch pad. If Starship lands on a pad at the same launch centre as the one it took off from, this would count. If it lands in a different location, this would not count
If it really matters it the moment of liftoff, local time, will be used to determine when a successful resolution took place.
Update 2026-01-19 (PST) (AI summary of creator comment): Tower catch counts as a valid landing method for this market.
