Deep News
Newsletter for the Deep Impact mission
Issue 13
July 2004

Welcome to Deep News. It's hard to believe that we are one year from impacting Comet Tempel 1, looking for the first time, deep inside a comet. We are looking forward to that spectacular evening! Looking back, this month also marks the one-year anniversary of this Deep News newsletter. Thanks to all of you who have followed along with us and especially to those of you who have made your own deep impact by sharing this exciting mission with others. If you would like to know more about the Deep Impact mission, visit our web sites at:

PI Update - Mission Update from Principal Investigator Dr. Mike A'Hearn
This month, Dr. Mike A'Hearn tells us about some recent observations of Comet Tempel 1 by the Hubble Telescope and Spitzer Space Telescope.

Gary Emerson - Amateur Astronomer for the Deep Impact Mission
Gary Emerson, one of our Small Telescope Science Program (STSP) astronomers and founder of the program, shares with us some of his observations of comet C/2001 Q4 and compares it to what scientists will see the night of encounter with Comet Tempel 1. Take a look at the images at http://deepimpact.jpl.nasa.gov/community/gemerson.cfm. If you would like to know more about our STSP program, visit http://deepimpact.umd.edu/stsp/.

Up Close and Personal - Meet Casey Lisse
Casey was already becoming a scientist by the time he was five years old working with cornstarch, tearing apart his father's electric razor and wondering why the sky was blue. Meet Casey Lisse from the University of Maryland. But before you do - lock up your razor!

Music to my ears, uh, I mean - my instruments!
The science team won't just point an instrument at Comet Tempel 1 during impact and catch whatever data comes their way. There has to be a very specific sequence set to gather data and it is a little like a symphony. Read Dr. Lucy McFadden's description of the sequence review at:
http://deepimpact.jpl.nasa.gov/science/observations-sequence.cfm

Density, porosity and strength?
This month, Ray Brown writes about density, porosity and strength and shares with us what an understanding those three factors will tell us about how comets were formed during the early period when the solar system was forming. First, read Ray's other articles on the science objectives for the Deep Impact mission:

Then you'll be ready for density, porosity and strength of a comet at:

Where is Deep Impact - Educators take a Virtual Field Trip
What's it like to take a virtual field trip for your educator training? The Roper Mountain Science Center in Greenville, SC tells us about how the Deep Impact mission went along for the ride.

Did you see our past Deep News Issues?
Visit http://deepimpact.jpl.nasa.gov/newsletter/archive.cfm to catch up on exciting past news from the Deep Impact mission.

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.
