Project in space of Greek god (6)
I believe the answer is:
apollo
'greek god' is the definition.
(Apollo is an example)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for apollo that I've seen before include "source of name for far-flung missions" , "Lad who's striking" , "US space flight programme, 1961-72" , "Greek god; large European butterfly" , "Divine figure" .)
