The October 28, 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 3: Earth is 2.9× as big as Brazil.
ROUND 1
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 Perseverance rover compared with a concert grand piano?
Reveal the answer
Answer: Perseverance Rover — 3 m. The Perseverance rover measures 3 m (length / span), which is 1.1× as big as the reference, a concert grand piano at 2.7 m.
Perseverance is about the length of a small car.
Common miss: players tend to compress the Perseverance rover when it sits beside a concert grand piano — big things get squeezed, small familiar things get stretched.
How tall is a Saturn V rocket compared with the Statue of Liberty?
Reveal the answer
Answer: Saturn V Rocket — 110.6 m. A Saturn V rocket measures 110.6 m (height), which is 1.2× as big as the reference, the Statue of Liberty at 93 m.
Saturn V stood taller than the Statue of Liberty without its pedestal.
Common miss: players tend to compress a Saturn V rocket when it sits beside the Statue of Liberty — big things get squeezed, small familiar things get stretched.
How tall is a Starship launch stack compared with a Saturn V rocket?
Reveal the answer
Answer: Starship Launch Stack — 121 m. A Starship launch stack measures 121 m (height), which is 1.1× as big as the reference, a Saturn V rocket at 110.6 m.
The complete Starship launch stack is about 121 metres tall.
Common miss: players tend to compress a Starship launch stack when it sits beside a Saturn V rocket — big things get squeezed, small familiar things get stretched.
