645 Harrison Street according to https://www.planet.com/contact ?

Which parameters for museum and subject ?

"showcasing information about the Solar System, cosmology, and spaceflight" as of https://en.wikipedia.org/wiki/Hong_Kong_Space_Museum

https://taginfo.openstreetmap.org/search?q=spaceflight#values
https://taginfo.openstreetmap.org/search?q=astronomy#values
https://taginfo.openstreetmap.org/search?q=aerospace#values

Probably multiple ? osm.wiki/Semi-colon_value_separator
"space" may be misinterpreted https://taginfo.openstreetmap.org/search?q=space#values
"science" values should correlate with "faculty" https://taginfo.openstreetmap.org/keys/faculty#values

"PFRR is owned by the University of Alaska Fairbanks (UAF) Geophysical Institute" https://en.wikipedia.org/wiki/Poker_Flat_Research_Range, so it's NOT "military"

Should be an area ?

probably a launchpad ? aeroway=spaceport

Which kind of crater ? node/357349420/history, see natural=crater

The entry is 7 years old, is it still correct ? On the website the address is given as the building on the opposite side of the street https://www.interior.gob.es/opencms/es/contacta-con-nosotros. If still the case, you could add https://taginfo.openstreetmap.org/tags/government=ministry

Many buildings within way/30648317 are also tagged as amenity=university which should only be building=university, probably with osm.wiki/Key%3Afaculty
