Knowing times for space mission (5)

Ross

I believe the answer is:

flyby

'space mission' is the definition.
(flyby is a type of space mission)

'knowing times' is the wordplay.
'knowing' becomes 'fly'.
'times' becomes 'by' (both can mean 'multiplied by').
'fly'+'by'='FLYBY'

'for' is the link.

(Other definitions for flyby that I've seen before include "Part of probe's track closest to the observed planet" , "Low pass at air display" .)

I've seen this clue in The Independent.
