We have all seen workers on a construction
site, hammering and drilling. Imagine a
construction site floating in space high
above the Earth’s surface. That’s what
astronauts have to cope with when they
are repairing a satellite, or
putting together a
space station.

Is it warm
today?
In orbit, the strong
sunshine heats
astronauts up.
Surprisingly, it’s difficult
to lose heat in space, so
spacesuits have to include
a refrigeration unit!
An astronaut may be
outside the space station
for hours at a time. This
one is working on the
station’s robotic arm.
Illustration of how a sunrise
would look from space.
Between 1998 and 2005,
more than 60 spacewalks
were performed. Each time
two astronauts worked on
the International
Space Station.
Astronauts say
that moving
their hands in their gloves is
difficult. To feel what they mean,
put a rubber band around your
closed fingers and try to
open them. Do this
fifteen times.
