Artificial satellite along with a — natural one? (7)
I believe the answer is:
miranda
'natural one?' is the definition.
The definition suggests a singular noun which matches the answer.
'artificial satellite along with a' is the wordplay.
'artificial satellite' becomes 'mir' (Russian space station).
'along with' becomes 'and'.
'mir'+'and'+'a'='MIRANDA'
(Other definitions for miranda that I've seen before include "Female in The Tempest" , "Heroine of The Tempest" , "Shakespearean heroine" , "Innocent heroine" , "The rights read by US police at the time of arrest" .)
