British recalling space traveller's instrument (9)
I believe the answer is:
balalaika
'instrument' is the definition.
(type of stringed instrument)
'british recalling space traveller's' is the wordplay.
'british' becomes 'b' (abbreviation e.g. in 'BBC').
'recalling' becomes 'a la' ('a la' something means in a way reminiscent of it).
'space traveller' becomes 'Laika' (Laika was a Soviet space dog).
'b'+'ala'+'laika'='BALALAIKA'
(Other definitions for balalaika that I've seen before include "Instrument with three strings and a triangular body" , "Russian triangular musical instrument" , "Russian "guitar"" , "Three-stringed instrument used to play Russian folk music" , "Three-stringed, triangularbodied Russian instrument" .)
