Two months ago, much of the world stopped to watch Comet Tempel 1 plough into the Deep Impact spacecraft and the
resulting spectacular release of a cloud of dust and gas. Some people watched through telescopes, and some watched the images sent
back from the flyby spacecraft by television or computer. Whatever the form of observation, it is true that it was a Deep Impact felt
around the world. For the past two, almost three months the science team has been hard at work studying the resulting data while the
engineering team planned and performed a maneuver to put the spacecraft on a new path and into a safe sleep mode. If you missed
any of this, you may want to take a look at our web site and read the newsletter below for new updates.

Picture This! - Put Your Best Nucleus Forward
David Stern, a member of the science team has been working with Co-Investigator Alan Delamere to combine comet nucleus images
from the impactor spacecraft into one composite at the highest resolution and the greatest spatial coverage. What is that process
like?

And Picture This! - Beauty is Skin Deep
Using a composite picture of the nucleus, the science team has been able to study the "skin" (surface features) of Comet
Tempel 1.

Mission Update - Updates from the Science Team
The science team has been working, meeting and presenting first results and then working, meeting, and presenting more results.
There is hardly time for them to catch their breath. Read on.

Up Close and Personal - Meet Olivier Groussin
Olivier completed his doctoral work in France three years ago. He worked for the Rosetta mission to a comet for a year in Berlin, and
now he is at University of Maryland. Olivier is a member of the science team analyzing the images and spectra data from encounter.

The Deep Space Network - Messages from Space
Millions of people on Earth were able to enjoy images from the Deep Impact spacecraft during encounter largely because the great
antennas of the Deep Space Network brought the images safely home to the mission team. Read the story of encounter from the point
of view of the DSN team.

And More on the DSN - Team Member Visits Goldstone
Once the encounter with comet Tempel 1 was over, some of our visiting team members became curious about the antennas that
brought the data down to earth - so they went to visit them at the Deep Space Network in Goldstone, California. Enjoy the tour!

Deep Impact Images - Making a "Spectrum of Yourself"
The Deep Impact flyby spacecraft sent back more than optical images of the encounter with Tempel 1. It also sent back infrared
spectra. It is from these data that the composition of the evolving ejecta plume is revealed, and the science team deciphers chemical
and molecular changes from the impact.

The Deep Impact mission is a partnership among the University of Maryland (UMD), the California Institute of Technology's
Jet Propulsion Laboratory (JPL) and Ball Aerospace and Technology Corp (BATC). Deep Impact is a NASA Discovery mission,
eighth in a series of low-cost, highly focused space science investigations. See
