rover

I'm a little stuck... Click here to teach me more about this clue!

'moon explorer' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?

'run across' is the wordplay.
'run' becomes 'r' (cricket abbreviation).
'across' becomes 'over' (synonyms).
'r'+'over'='ROVER'

Can you help me to learn more?

(Other definitions for rover that I've seen before include "Itinerant person" , "Vehicle driven remotely over extraterrestrial terrain" , "Wanderer, rolling stone" , "Nomad" , "Wanderer, archery mark" .)
