Made for $108 million, "The Martian" received a publicity booster earlier in the week when NASA announced it had found evidence of water on the surface of Mars - a cosmically fortuitous tie-in for a movie that celebrates NASA ingenuity.
What's the meaning of "a cosmically fortuitous tie-in"?
Is it just a pun? Can I just interpret it as a lucky or serendipitous connection or coincidence?
Tie-in has more than two meanings, and I'm not sure which one is more relevant.
1) A connection or association:
2) A book, film, or other product produced to take advantage of a related work in another medium
In addition to this, I have a poor grasp of how 'cosmically' and 'fortuitous' are combined and make a sense.
