Instructions: Name That Astronaut

_ _ _ _ A


1 Answer 1


Taking out my calculator, I find that all of the $r(t_i)$ numbers are close to integers, all within the 1-11 range that appears in the diagram.

  • $r(t_1) = 1$
  • $r(t_2) \approx 9$
  • $r(t_3) \approx 5$
  • $r(t_4) \approx 7$

So I think that the “astronaut” (or “cosmonaut”) you're looking for is:

LAIKA the dog, who was launched into space by the Soviets in 1957. Her name satisfies the letter pattern [AL][AI][IK][AK]A from the boxes connected to the numbers 1, 9, 5, 7 in the diagram.

The question title is:

a reference to Scooby-Doo, thus hinting at a dog. “Don't” may be a reference to the fact that Laika never returned from space, dying of overheating while in orbit.

OP Edit:

r(t4) is the number 2.47761 in roman numerals
