Newsletter for the Deep Impact mission
Issue #24, July 2005
--------------------------------------------------------------------------------
On July 4 at 5:52:24 Universal Time the Deep Impact team, received confirmation
that the mission they had put into action in November of 1999 had reached
success when the first image of a newly impacted comet Tempel 1 flashed onto
the screens of the control room at Jet Propulsion Laboratory. The dark icy
nucleus with its own "fireworks" display showed that the impactor
spacecraft, released from its flyby spacecraft 24 hours before had not only
guided itself to the sunlit side of the comet nucleus, but had collided hard
enough to brighten the comet coma so that the difference could be seen through
telescopes on Earth. Did you see it? If not, you will want to visit our web

PICTURE THIS - MAKE A DEEP IMPACT
This image of the dark black nucleus of Comet Tempel 1 shows the ejecta plume
caused by the impactor crashing into the icy surface. Those watching from Earth
were actually able to see the plume grow as the images were returned through
the antennas of the Deep Space Network.

AND PICTURE THIS - RAINBOW DATA
The science team is processing the images from the spacecraft in many ways to
give them different kinds of information. Take a look at the way in which
giving this image "false color" can help define the shape of the
ejecta plume.

HERE'S LOOKING AT YOU - COMET!
One of the unique factors of the Deep Impact mission is the varied kinds of
observation that took place during the collision between the comet and the
spacecraft - both in space and on Earth. Take a look at the following kinds of
images that the science team will use to compare and confirm their theories
about Tempel 1 and comets in general.

UP CLOSE AND PERSONAL - MEET ANNE ELSON
Someday she and her husband hope to build an entirely green (energy wise)
house. Although she is a pilot in her spare time, on this mission, Anne worked
on contingency plans for the flight of the spacecraft. Meet Anne Elson.

THIRD TIME'S A CHARM - AIMING AT THE COMET!
What may have looked like a near miss to our NASA TV audience was really a
carefully rehearsed set of maneuvers performed just as they had been in our
technical rehearsals. Take a look at where the impactor might have hit had the
team not prepared those maneuvers carefully.

DISCOVERY CHANNEL AND THE DEEP IMPACT "COMET COLLISION"
For those who may have missed the spectacular evening of encounter, this
premiere program produced by New Pony Productions chronicles NASA's Deep Impact
mission from the very beginning to the explosive finish, using state-of-the-art
digital imaging to recreate the craft's journey and ending with footage of the
actual impact transmitted from space. Make sure to check your local listings for
this exciting program Sunday, July 31st -
