Starship = the second stage
Land = a successful landing. After it comes to rest vertically Starship should neither move, explode nor burst into flames for a period of 60 mins (if SpaceX deliberately moves the spacecraft in this hour that will obviate the no-moving requirement)
"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
Question has increments of 0.05 years, so bet slightly cautiously. If it really matters it the moment of liftoff, local time, will be used to determine when a successful resolution took place.
If this does not take place before 2026.8 this question will resolve to 2026.85

@JoshuaWilkes I meant in terms of landing and having a small fire, basically after landing there's still some propellant left in the cooling channels, that gets burned and occasionally leads to small fires. IIRC we see that on Falcon 9s, and they have automated extinguishers for it, by it doesn't blow up or impede reuse. I could imagine something like that happening for Starship
