SUNDAY PUZZLE — Well, here it is, folks! I have nothing to add to the celebration except to refer you to our coverage, in case you eschewed the news online in favor of a more tranquil cerebral bubble. Oh, and I do hope that we get a crossword trip to the moon one day and a Jeff Chen and Jason Mueller lecture at Tranquility Base.

The Times knows how to do commemorative grids. Mr. Chen has a bunch on his site: There was a series around the end of the 20th century, a huge bicentennial puzzle in 1976 and this wild centennial of the Titanic, to name a few. I think that our constructors did a strong job today; Mr. Mueller’s original idea was out of this world but probably would have required a double-sized grid. We can always circle back in another 50 years.

Tricky Clues

I have to say, I got swept up in the hunt for theme answers as soon as I sat down to this puzzle because I knew what it had to be about from the title. We know enough about Mr. Chen to know that any puzzle of his will have pro-level cluing (by the way, this is his centennial grid with us, if you want another event to commemorate). So I do not have that big of a list today; just a few that slowed me down.

33A: I thought this particular talent had to do with reading minds but it looks like TELEPATHS might be opened books as far as transmitting thoughts go. Also, we might all be telepathic, given the right technology.
