Different areas cope with NASA's business (9)
I believe the answer is:
aerospace
'nasa's business' is the definition.
I can't tell whether this definition defines the answer.
'different areas cope' is the wordplay.
'different' indicates anagramming the letters.
'areas'+'cope'='areascope'
'areascope' anagrammed gives 'AEROSPACE'.
'with' acts as a link.
Can you help me to learn more?
(Other definitions for aerospace that I've seen before include "Technology of flight" , "zone near Earth" , "Branch of technology including aviation" , "Technology of planes, rockets, etc" , "The aviation world" .)
