Science for today’s Tough Trivia question: The Saturn V rocket stack was the super heavy-lift launch vehicle that took the US manned space program to the Moon. It was—and remains—the tallest, heaviest, and most powerful rocket brought to operational status. It holds the records for the heaviest payload launched and largest payload capacity to low Earth orbit (310,000 pounds). It is also, still, the only launch vehicle to carry humans beyond low Earth orbit. Fifteen were built, but only thirteen were flown, all launching from Kennedy Space Center, in Florida, between November 9, 1967 (the uncrewed Apollo 4) and May 14, 1973 (Skylab). Do you know how tall it was? How heavy? And what percentage of the stack actually returned to Earth from the Apollo missions to the Moon?

Yesterday’s question was: It seems our most famous artists are either mononymous or pseudonymous, but before they were artists, they were children who were given full names by their parents. How many of these noms d’art can you fill out as they would have appeared on their birth certificates (if birth certificates had been a thing when and where they were born): Donatello, Michelangelo, Raphael, Titian, El Greco, Rembrandt, Hokusai, Hiroshige, Grandma Moses, Toulouse-Lautrec, Erté, Christo, Jeanne-Claude?

The answers are:

Donatello: Donato di Niccolo di Betto Bardi (born circa 1386, lived his whole life in Florence, died December 13, 1466)

Ian’s Tough Trivia is a daily feature of this blog (Monday’s category is History; Tuesday is Arts; Wednesday is Science; Thursday is Entertainment; and Friday is Grab Bag). Each day, I post a tough question, as well as the answer to the previous day’s question. Simply comment on this post with your answer. I’ll approve the comments after the next question is posted. Sure, you can probably find the answers by searching the web, but what’s the fun in that?

And if you’ve got a favorite trivia question—or even just a topic for which you’d like to see a question—let me know! Reader participation is warmly encouraged.
