t’s easier to build things on earth than in space,
so pieces of the ISS will be built on Earth and
flown into space. Some of the pieces are the size
of a school bus, and some are even larger!
The pieces will be flown into space and put
together by astronauts. Just think of the ISS as
a giant model. It will take 45 Space Shuttle
missions and over 4 years to carry the pieces
of the ISS into orbit. That’s about one Shuttle
launch each month. Russia, Japan and the
European Space Agency will also launch rockets
carrying parts of the ISS.
Astronauts will walk in space and use special tools
to put the ISS together. It will take over 2,000 hours
of space walks to put the ISS pieces together. That’s
more time in space than all the other space walks
combined!
The International Space Station
- Global Teamwork -
ow that countries are working together, amazing
things are happening in space exploration. The
most incredible is the International Space Station, or ISS.
The ISS is a huge laboratory
in space where astronauts
and scientists from 16
different countries will
live for months at a
time. The learning
that takes place on
the ISS will one day
be used to help
humans travel to
Mars and beyond.
The station will be
larger than a football
field and the part of the
ISS where astronauts will
live and work will be bigger
than a 747 jet plane. The ISS will
be so big you will be able to see it pass
overhead from your backyard.
