let's see
[Music]
hello paxy my name is ann mclean and i'm
an astronaut here on board the
international space station or iss
it's so nice to have you on board today
and today i want to tell you about very
interesting facts about the space
station
so paxi when you look around the space
station you can see that we have quite a
lot of room
[Music]
we can pass each other easily and we can
work fully stretched out in fact the iss
is the largest man-made object ever
built
the inside area of the station where we
live and work is as big as a jumbo jet
and it weighs 420 tons that's the
equivalent of 350 normal cars
the station is enormous
now space station needs to be big to
accommodate all of the astronauts and
all the experiments that we do
more than 200 people have visited the
iss from 15 different countries and
humans have lived on iss continuously
for 19 years
the first part of space station was
launched in 1998 and the first humans
arrived in 2000
even though the space station is so big
the iss is moving through space at 28
000 kilometers an hour with this speed
we go around the whole earth in one and
a half hours and you know what that
means paxi we see 16 sunrises and 16
sunsets every day
the station is a very impressive
construction but it has not been cheap
in fact it's the most expensive object
ever built by humans and has been
estimated around 120 billion dollars
for this money you could build six
tunnels between france and england or 80
of the tallest buildings on earth or you
could host the olympic games three times
speaking of olympic games the olympic
torch made its way to the space station
and went on a spacewalk
now the torch is an international icon
of cooperation but of course it had to
come out without its flame because that
would be very dangerous up here in space
station
the torch was set in 2013 along with new
supplies which brings us to my next fact
paxi we need approximately seven tons of
supplies to support three astronauts for
six months here aboard space station
that's a lot of stuff and this is
despite the fact that we recycle air and
water
now like a house on earth the space
station also needs energy the iss is
powered by giant solar panels if you put
them all next to each other they're as
big as eight basketball courts the solar
panels constantly rotate to catch as
much sunlight as possible
the energy from the solar cells must be
transported to the different parts of
the space station now that's a long way
paxi
in fact for this the iss requires 13
kilometers of wires
to get a sense of that length that would
be like climbing the tallest building on
earth
15 times
[Music]
now the space station is very important
but it's also very complex
we have 52 computers monitoring our
systems which monitor over 350 000
sensors all to make sure that space
station is operating normally our
experiments are functioning properly and
that we're living here safely
so paxi i hope that you see that this
space station is an amazing place in so
many ways but it also requires a lot of
logistics and planning to run smoothly
it really is a place of world records
paxi i hope to see you back on the space
station soon what are we going to talk
about next time
bye
[Music]
you
