All are at the time of moon walk unless otherwise specified.
Add your own. Should be easily verified (ie nothing like "they love pineapple on pizza").
Intention is "what will be the properties of Neil Armstrong 2.0".
In general, all items are taken to be "as publicly known, at the time of the landing". So if the astronaut is trans but stealth and this has somehow not come up, it would resolve 'NO' for 'is transgender'. Similarly, if they came out as trans 10 years later, it would not change the resolution retroactively.
Things that might not be known for a while (e.g. a video of them falling/dancing) will have at most 12 months post-moonwalk to appear, and if they don't appear will resolve NO. I will try to make sure I edit any such items so it is clear for betters.
