Mission Fact
On the evening of July 3, 2005, Deep Impact, a NASA Discovery Mission, performed an incredibly complex experiment in space to probe beneath the surface of a comet and reveal the secrets of its interior. As a larger “flyby” spacecraft released a smaller “impactor” spacecraft into the path of comet Tempel 1, the experiment became one of a cometary bullet chasing down a spacecraft bullet while a third spacecraft bullet sped along to watch.

About GIS Title Image


Geographic Information Systems - GIS

The SMD Resource Locator tool is built on GIS technology. As defined on GIS.com

"... a GIS combines layers of information about a place to give you a better understanding of that place. What layers of information you combine depends on your purpose..."

Mapping where things are lets you find places that have the features you are looking for and to see where to take action. People use maps to see where or what an individual feature is. Also, by looking at the distribution of features on the map instead of just an individual feature, you can see patterns emerge. All of this helps us process data in a way that makes sense.

SERCH uses GIS software created by the Environmental Systems Research Institute (ESRI,Inc.). To learn more about the software and GIS applications visit the ESRI web site. To get a better general understanding of GIS, visit GIS.com.
