four-and-a-half billion years ago a vast
celestial body slammed into the young
earth the violence of the impacts flung
a cloud of debris into orbit cold and
gravity did the rest
forming the Earth's natural satellite
the moon but ours isn't the only moon
there are many other moons in our solar
system and some scientists consider them
to be worlds in their own right where
life in some form might exists so a
number of missions have spent time aimed
at exploring them further jupiter at the
giant planet has moves that NASA's 1995
galileo probe spent eight years
exploring they include the Selfridge for
canon Furner of Io
and Europa lurking in the coldest part
of the system hidden beneath its frozen
crust and immense liquid ocean in
december two thousand the joint NASA
European Space Agency mission
cassini-huygens took the first-ever
high-resolution photos of Jupiter and
its moons as it passed towards its main
goals satin its rings and it's system
launched in 1997 it took seven years for
cassini-huygens to reach Saturn's orbit
on a mission scheduled to last until
2011 cassini-huygens has revealed much
about the structure of Saturn's rings
which are made up of millions of lumps
of recognize orbiting the gaseous planet
like an army of many moves it also
captured the first images of Phoebe the
most distant of Saturn satellites and it
revealed the pristine beauty of
Enceladus the ice moon with its dramatic
volcanoes and it's south pole at the
Free University of Berlin another
research project examines the craters
made by meteorites crashing into yeah
Pater's another of Saturn's moons
discovered in 1671 by the astronomer
Jean Dominy Cassini this icy celestial
body 1,500 kilometers in diameter has a
number of unusual topographical features
almost half of its surface is as dark as
coal while the other half is as bright
as snow images from the probe taken in
2004 also reveal an icy Ridge running
almost entirely
and its equator and then there's Titan
Saturn's biggest and most fascinating
move in january 2005 the European lander
Huygens separated from Cassini it's set
down as planned and on time and what it
sent back stunned the scientific world
Huygens lasts barely a few minutes on
Titans hostile surface but in that time
it open new horizons which is why your
plans to do more exploration at national
and international level in the near
future the european space agency will
for example be part of chandler am the
Indian lunar mission indeed the quest to
explore the universe is moves including
our own is far from over I can rub the
only person on it doesn't have TV
coverage to the food and man they got
the black up now you're gonna be with us
for more TV picture now have
they are gay
a picture with him out
I want all the time
