Newsletter for the Deep Impact mission
The Deep Impact twin spacecraft spent their third month heading toward Comet Tempel 1. Having finished the
Commissioning Phase of the mission, the team now continues Cruise Phase. What are "Commissioning", "Cruise Phase" and the
Deep Impact mission, you ask? Read this month's newsletter below and take a look at our mission web sites at:
Picture This! Now you see it...!
In March, this picture was taken of Comet Tempel 1 as it began to develop a dusty halo around its nucleus. This halo, called a
coma, forms as a comet approaches the Sun and its nucleus's surface heats releasing jets of gas and dust.
Find out more about how that coma forms on a comet:
The latest on Deep Impact
The Deep Impact mission finished Commission Phase and moves on to Cruise Phase. Read about the team's activities only
months away from encounter with Comet Tempel 1.
And Picture This! Down to Earth
Last month we showed you images of Jupiter taken by the Deep Impact spacecraft's imaging instruments during testing in
space. This month, we get a little more "down to earth" by showing you a simulation of our own planet, specifically, the side
of Earth that will be able to watch impact between the spacecraft and Comet Tempel 1 in July.
Up Close and Personal - Meet Dr. Lucy McFadden
When Lucy was in college, she chose a class because she couldn't understand what radios and astronomy had to do with each
other. The answer helped lead her to a position as a science team member on Deep Impact. Lucy thinks you shouldn't be
afraid to ask questions - so let's ask her a few.
Food for thought - Comet snacks that teach science
Hey Kids, take a look at yummy snacks you can have fun making with your family, school or whole community. You'll learn
about comets, too! This would be very cooool for your next carnival or community event.
Questions From You - What will we see during encounter?
Less than 3 months from encounter with Comet Tempel 1, this is the question we get most often. So, we dedicated a whole
section or our web site to give you answers. Here is the: who, what, where, and when, about observing Deep Impact in July

For Educators - Your students can do hands-on activities that connect them to real-life space events.
An independent evaluation group, Magnolia Consulting, is currently seeking educators in both formal and informal settings to
implement various educational modules related to NASA's Deep Impact mission. The materials apply to a range of student
grades, from elementary through high school and implementation would occur over a 1-3 week period this spring. Take a
look at the details:
Happenings in Hawaii
The Mauna Kea Astronomy Education Center will sponsor an educator workshop combining the history of navigation in
Hawaii and the science of the Deep Impact mission during the last week of June 2005. To find out more about
