       Launch: October 1989
       Arrive: December 1995
       Crashes into Jupiter:
       September 21, 2003
•The Galileo spacecraft and its Inertial Upper
Stage booster rocket were deployed from the
space shuttle Atlantis October 18, 1989.
•Shortly thereafter, the booster rocket fired
and separated, sending Galileo on its six-year
journey to the planet Jupiter.

                 •Upon its arrival at Jupiter in
                 December 1995, Galileo
                 released a probe into the
                 atmosphere that gathered data
                 on the composition of the
                 planet's clouds.
                 •The orbiter relayed probe
                 information back to Earth and
                 surveyed and photographed
                 Jupiter and some of its major
                 satellites.
•Galileo's mission was
to study Jupiter and its
moons in more detail
than any previous
spacecraft.
•The spacecraft is
named in honor of the
first modern
astronomer --- Galileo
Galilei. He made the
first observations of the
heavens using a
telescope in 1610.
    This picture of Antarctica is a mosaic of 40 images obtained by the Galileo
spacecraft's camera using the red, green, and violet filters. When the images were
  taken several hours after Galileo's first Earth flyby on December 8, 1990, the
      spacecraft was about 200,000 kilometers (124,000 miles) from Earth.
View of Australia from Galileo
Eight days after its
second encounter with
the Earth, the Galileo
spacecraft was able to
look back and capture
this remarkable view of
the Moon in orbit about
the Earth, taken from a
distance of about 6.2
million kilometers (3.9
million miles), on
December 16, 1992.
These four images of the Moon are from data acquired by the Galileo
 spacecraft's Near-Infrared Mapping Spectrometer during Galileo's
                December 1992 Earth/Moon flyby.
This is the orbital tour that Galileo
        took while at Jupiter

 The great red spot on Jupiter is a huge storm made visible by variations
in the composition of the cloud particles. The Red Spot is not unique, but
 is simply the largest of a class of long-lived vortices, some of which are
                   visible in the lower part of the image.
In 1994, Galileo was perfectly positioned to
watch the fragments of comet Shoemaker-
         Levy 9 crash into Jupiter.
 A portion of a chain of impact craters on Jupiter's moon Callisto is seen in this
image taken by the Galileo spacecraft on November 4, 1996. This crater chain
 on Callisto is believed to result from the impact of a split object, similar to the
     fragments of Comet Shoemaker- Levy 9 which smashed into Jupiter's
                           atmosphere in July of 1994.
The cone-shaped Galileo probe entered the atmosphere of
 Jupiter on Dec. 7, 1995, at a speed of over 106,000 mph
   and survived deceleration forces of 228 times Earth's
 gravity. After deploying a parachute, it relayed data to the
    Galileo orbiter spacecraft overhead for 57 minutes.
It appeared that Jupiter's atmosphere is
drier than thought. Measurements from
the probe showed few clouds, and
lightning only in the distance. It was
only later that it was discovered that the
probe had entered an area called a "hot
spot."

Towards the end of the descent, the
probe measured winds of 450 miles per
hour - stronger than anything on Earth.
The probe was finally melted and
vaporized by the intense heat of the
atmosphere.
      What’s in store for Galileo?
                        Galileo will crash into
                        Jupiter on September 21,
                        2003, ending its 14 year
                        mission.




Where is Galileo now?
  In the Future
The Jupiter Icy Moons
Orbiter is an ambitious
proposed mission to orbit
three planet-sized moons
of Jupiter -- Callisto,
Ganymede and Europa --
which may harbor vast
oceans beneath their icy
surfaces. The mission
would launch in 2012 or
later.
The Jupiter Icy Moons Mission
could shed light on Europa, a
mysterious moon of Jupiter.
