Spectroscopes at Use

The Deep Impact flyby spacecraft by NASA will include a Spectroscope, which contains an infrared spectrometer. This means that while some of the pictures that the flyby spacecraft takes there will also be information about infrared energy released in gases in the comet. This spectroscope will be aimed at the ejected matter as the crater forms, and an infrared "fingerprint" of the material from inside of the comet's nucleus will be taken.

Once these data are collected, they can be analyzed and compared by scientists back on earth.
