The October 17, 2026 puzzle ran from the Apollo Lunar Module at 6.9 m to the Moon at 3,474.8 km — 5 orders of magnitude apart, drawing on space. The pair furthest apart was round 1: a Space Shuttle orbiter is about 1.9× smaller than a Boeing 747.
ROUND 1
How long is a Space Shuttle orbiter compared with a Boeing 747?
Reveal the answer
Answer: Space Shuttle Orbiter — 37.3 m. A Space Shuttle orbiter measures 37.3 m (length / span), which is about 1.9× smaller than the reference, a Boeing 747 at 70.7 m.
The orbiter alone is about as long as a short-haul airliner — the launch stack was far taller.
Common miss: players tend to inflate a Space Shuttle orbiter when it sits beside a Boeing 747 — 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.
How long is the Hubble Space Telescope compared with an American school bus?
Reveal the answer
Answer: Hubble Space Telescope — 13.1 m. The Hubble Space Telescope measures 13.1 m (length / span), which is 1.2× as big as the reference, an American school bus at 10.7 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 an American school bus — big things get squeezed, small familiar things get stretched.
How tall is the Apollo Lunar Module compared with an adult giraffe?
Reveal the answer
Answer: Apollo Lunar Module — 6.9 m. The Apollo Lunar Module measures 6.9 m (height), which is 1.3× as big as the reference, an adult giraffe at 5.2 m.
It stood about as tall as a two-storey house, and only the top half ever came back.
Common miss: players tend to compress the Apollo Lunar Module when it sits beside an adult giraffe — big things get squeezed, small familiar things get stretched.
