Space hat-ellite
Satellites can be any shape at all
– even hat shaped. They don’t
need to be streamlined, because
there’s no air in space.
Slipping
through air
A spacecraft has
to be streamlined
to move easily and
safely through air.
Where necessary, an
extra part called a
fairing is added to
achieve this effect – a
nose cone is a fairing.

rocket boosters) are streamlined
for lift-off.
