Satellite perhaps bore it out -- Russia's first (7)
I believe the answer is:
orbiter
'satellite perhaps' is the definition.
(I've seen this before)
'bore it out russia's first' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'first' suggests taking the first letters.
The initial letter of 'russias' is 'r'.
'bore'+'it'='boreit'
'boreit' anagrammed gives 'orbite'.
'orbite'+'r'='ORBITER'
(Other definitions for orbiter that I've seen before include "Satellite perhaps" , "Craft going round planet" , "One goes round" , "Space vehicle" , "Non-landing spacecraft" .)
