Newsletter for the Deep Impact mission
Issue 23
June 2005

Encounter is less than one month away and as the spacecraft and Comet Tempel 1 approach each other, the project team makes last minute preparations for an evening of celestial fireworks as we make, for the first time ever, a deep crater in a comet to see what is beneath the surface. If you want to know more about the Deep Impact mission, take a look at:

Picture This! - Image from the Spacecraft
One of the latest images from the spacecraft shows that it is drawing closer and closer to Comet Tempel 1.

On June 9, 2005, Principal Investigator Dr. Mike A'Hearn, Project Manager Rick Grammier and science team member Don Yeomans represented the Deep Impact mission at NASA Headquarters for a briefing to the press.

And Picture This? - Image from an Amateur Astronomer
While the spacecraft sends images of its approach to Comet Tempel 1, pictures also come to us from amateur astronomers peering through their telescopes on Earth.

More Images from Space and Earth
To see other new images from the spacecraft and ground observation, take a look at the Deep Impact Image Gallery.

Mission Update - From the Engineering and Science Teams
This month, Keyur Patel, Deputy Project Manager gives an update on what the engineering team is doing to prepare for encounter while Lucy McFadden gives us an update on the science team's meeting last week to discuss encounter.

Up Close and Personal - Meet Leticia Montanez
Leticia loves aerospace work because it blends her three favorite pastimes - art, science and math. When she's not at work, she is often somewhere else in the world competing on the Women's Ice Hockey Travel Team. In both cases, she is working on something icy! Meet Leticia Montanez.

Rehearsing for 800 seconds of impact - What is an ORT?
ORT - it stands for Operation Readiness Test, a dress rehearsal for the night of encounter. The team has had two and is heading toward its third.

Who Else is Watching Deep Impact?
Since November of 2004, advanced amateur astronomers participating in the Small Telescope Science Program have been imaging comet 9P/Tempel 1. Their images and resulting photometry are complementing data acquired by large telescopes. Since April, participants have been providing nearly daily images of the comet.

We Can Take it - and We Can Dish it Out!
A mission team can put a spacecraft into space and likewise, a spacecraft can gather data for months. But if there is no way to get the signals back and forth between the two, all is lost! That's what makes the antennas (sometimes called "dishes") of the Deep Space Network so important to space exploration. Learn more about the DSN and the antennas that will give overlapping coverage on the night of encounter.

Creating a Crater - What a Blast!
In order to make decisions on Earth about how to make a crater in Tempel 1, the project team models impacts in different kinds of materials whose structure might be consistent with that of the comet. Pete Schultz, a member of the Deep Impact science team shares his latest impact models with us.
