Interstellar travel target adjusted at pre-launch — excellent to adopt that (5,8)
I believe the answer is:
alpha centauri
'interstellar travel target' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'adjusted at pre-launch excellent to adopt that' is the wordplay.
I cannot quite understand how this works, but
'excellent' could be 'ace' (ace can informally mean very good) and 'ace' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for alpha centauri that I've seen before include "Nearest bright star to the solar system - run a caliphate (anag)" , "Brightest star in Centaurus" , "Sun's closest star system" , "Bright southern star" , "Star nearest Earth" .)
