Severe reprimand given in space vehicle (6)
I believe the answer is:
rocket
I believe this clue is a double definition.
'severe reprimand' is the first definition.
(as in 'getting a rocket' from a someone)
'space vehicle' is the second definition.
'given in' acts as a link.
(Other definitions for rocket that I've seen before include "High speed steam engine (1829)" , "Firework - salad plant" , "Self-propelled firework or missile" , "Severe reprimand" , "Go up very quickly" .)
