ROUND 1
Mars — 6,779 km
Answer: Mars measures 6,779 km (length / span), which is 1.6× as big as the reference, Brazil at 4,320 km.
Mars is a little over half Earth’s diameter.
Common miss: players tend to compress Mars when it sits beside Brazil — big things get squeezed, small familiar things get stretched.
Answer: the Moon measures 3,474.8 km (length / span), which is about 1.3× smaller than the reference, the contiguous United States at 4,500 km.
The Moon’s mean diameter is about 3,475 kilometres.
Common miss: players tend to inflate the Moon when it sits beside the contiguous United States — big things get squeezed, small familiar things get stretched.
Answer: 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.
Answer: the Apollo Lunar Module measures 6.9 m (height), which is 3.4× as big as the reference, a US interior door at 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 a US interior door — big things get squeezed, small familiar things get stretched.
