This might be a double definition.

'nasa probe' is the first definition.
'mariner' can be an answer for 'probe' (I've seen this before). I'm not certain of the 'nasa' bit.

'sailor' is the second definition.
(I know that sailor can be written as mariner)

Can you help me to learn more?

(Other definitions for mariner that I've seen before include "Sea dog" , "Person sailing" , "Seaman" , "Man of the sea" , "Jack" .)

I've seen this clue in The Daily Mail.
