Men on the moon
281
Because the moon has no atmosphere.
Neil
Armstrong
Here comes Earth
Instead of the moon rising,
the astronauts saw
Earth rising over the
moon’s horizon – it
looked four times
bigger than the
moon looks
from Earth.
We have transport!
Three later
Apollo
missions
each carried a small electric car,
a lunar rover, which allowed the
astronauts to explore away from
the lander. These were left on the
moon when the astronauts left.
Splashdown
The astronauts returned to
Earth in the
Apollo 11
command
module. This fell through the
atmosphere and landed in the
Pacific Ocean. A ringed float
helped to keep it stable.
One lunar rover
reached a top
speed of 22 km/h
(13.5 mph).
This dish
antennae
allowed the
astronauts to
send pictures
to Earth.
How did they talk?
There’s no air in space, so
sound has nothing to travel
through. Lunar astronauts
use radio equipment in
their helmets.
