Deep News
Newsletter for the Deep Impact mission
Issue 22
May 2005

With less than two months until the Deep Impact encounter with Comet Tempel 1, we invite you to see why this will be one of the most daring experiments in space that NASA has ever launched. How will this experiment work? What will you see? What do scientists expect to find? For answers to these and other exciting questions, read this month's newsletter below and take a look at our web sites at:

Picture This! Comet Tempel 1 approaches encounter point
We are now able to see Comet Tempel 1 both from the Deep Impact spacecraft instruments and large and small telescopes on Earth. Take a look at this beautiful icy body in an image taken from Kitt Peak National Observatory in Arizona.

Mission Update - Reports from our team
Our mission update comes from a series of team reports to remind you that it takes a lot of people in different areas to design and fly a mission.

Can you guess the size of the crater?
If you think you can figure it out using our clues, take a look at the new contest from the Planetary Society to guess the size of the crater we will make when Comet Tempel 1 collides with the Deep Impact spacecraft in July 2005.

Up Close and Personal - Meet David Martin, Webmaster - Deep Impact
David had no clue that a love for computers would lead him to the job of bringing a space mission's web site to the world - but it did! Meet David Martin.

Comet Crunch - The Deep Impact ice cream!
Yes, it's true. The Deep Impact mission has its own ice cream. Introduced at the campus' annual open house Maryland Day, and created by the University's own dairy, this ice cream is making an impact with students. What would an ice cream created to remind us of a comet taste like and how did it come to be? Read on.

Educators - A new activity on observation from Earth
Eyes on the Skies, an activity created by the Deep Impact mission and McREL gives students an appreciation for the challenge of collecting data and analyzing it from both space and from Earth. Take a look at this activity:

To take a look at ways to observe Comet Tempel 1 as it approaches encounter point, check our Amateur Observers' Program web site:

As your students leave for the summer, make sure they will plan to watch this incredible July event with their families by reviewing activities like Comet on a Stick, Make a Comet and Eat It and others on our page especially for educators:

For Kids! Check out our games and puzzles
If you haven't looked at our Discovery Zone lately, now is the time to play all the games and puzzles about comets and the Deep Impact mission:

Questions from you - They just keep on coming
We wanted to remind you of answers to some of our most common questions:

What are the science objectives?

Will you knock the comet out of its orbit?

What will we be able to see from Earth and from where during encounter?

Can I know more about the mission?

Can I know even more about the mission?
