Newsletter for the Deep Impact mission
Issue 27
October 2005

The Deep Impact flyby spacecraft is quietly sailing through space, while on the ground, the science team continues to pursue new findings from the space and ground data of the encounter with comet Tempel 1 in July 2005. Several findings have been released through various papers and articles written by the Deep Impact science team and others around the world. Check out the Deep Impact web site at:

Picture This! - Hot as Ice?
Recently, the science team released a temperature map of the nucleus of comet Tempel 1. How does the science team use color to represent temperature? Take a look.

And Picture This! - The Colors of Your Mind
Color doesn't just tell us about temperature. The science team sometimes uses color to communicate intensity of light. What is falsi color?

Colors of the Rainbow - What is Falsi Colori?
Scientists impose color to images to communicate dramatic or subtle differences in their data. Noah Goldman gives perspective on how the science team uses color.

Mission Update
This month, the Deep Impact science team looks at new kinds of data. The journey to understand the composition and structure of a comet continues.

Up Close and Personal - Meet Lori Feaga
If she weren't researching data from the Deep Impact mission, she might be arranging your vacation. Which one did she always dream of doing? Meet Lori Feaga and find out.

A Funny Thing Happened on the Way to the Comet
The journey to the comet Tempel 1 nucleus was not without drama. Ray Brown tells us about the impactor spacecraft's last moments before colliding with the nucleus and the science being gathered from the data.

If you need some background on the science team's original objectives for the mission, Ray wrote a series of articles about the way in which they would be met.

Questions from You - Can the Spacecraft Go Back to Tempel 1?
Could the flyby spacecraft return to comet Tempel 1 and observe the impact site? Bill Blume gives reasons why that is not in the team's future plans.
