The November 8, 2026 puzzle ran from the Perseverance rover at 3 m to Earth at 12,742 km — 6 orders of magnitude apart, drawing on space. The pair furthest apart was round 5: Earth is 2.9× as big as Brazil.
ROUND 1
How long is the Hubble Space Telescope compared with a Tyrannosaurus rex?
Reveal the answer
Answer: Hubble Space Telescope — 13.1 m. The Hubble Space Telescope measures 13.1 m (length / span), which is 1.1× as big as the reference, a Tyrannosaurus rex at 12.3 m.
Hubble is roughly the size of a school bus, which is exactly what the Shuttle’s cargo bay was built to hold.
Common miss: players tend to compress the Hubble Space Telescope when it sits beside a Tyrannosaurus rex — big things get squeezed, small familiar things get stretched.
How long is the Perseverance rover compared with a three-seat sofa?
Reveal the answer
Answer: Perseverance Rover — 3 m. The Perseverance rover measures 3 m (length / span), which is 1.4× as big as the reference, a three-seat sofa at 2.2 m.
Perseverance is about the length of a small car.
Common miss: players tend to compress the Perseverance rover when it sits beside a three-seat sofa — big things get squeezed, small familiar things get stretched.
How long is a Space Shuttle orbiter compared with an Argentinosaurus?
Reveal the answer
Answer: Space Shuttle Orbiter — 37.3 m. A Space Shuttle orbiter measures 37.3 m (length / span), which is 1.1× as big as the reference, an Argentinosaurus at 33 m.
The orbiter alone is about as long as a short-haul airliner — the launch stack was far taller.
Common miss: players tend to compress a Space Shuttle orbiter when it sits beside an Argentinosaurus — big things get squeezed, small familiar things get stretched.
How long is the International Space Station compared with a Boeing 747?
Reveal the answer
Answer: International Space Station — 109 m. The International Space Station measures 109 m (length / span), which is 1.5× as big as the reference, a Boeing 747 at 70.7 m.
The ISS spans roughly 109 metres across its solar arrays.
Common miss: players tend to compress the International Space Station when it sits beside a Boeing 747 — big things get squeezed, small familiar things get stretched.
