We started watching the Netflix series Challenger around the time I published this puzzle - I think it inspired some of the NASA related clues. I highly recommend the show! I think a lot of times docuseries tend to drag things out a bit to squeeze out a few more episodes, but Challenger kept the pace going and each episode was engrossing.
On an only somewhat related note, the word series is both singular and plural, so I'm assuming that docuseries behaves the same way. But it sure looks funny to my eye in the paragraph above!
