2. Mission Statement & Goals:
The Sun Spectro Sat (SSS) is a high altitude spectrometer that measures how the spectrum of ambient sunlight varies at different altitudes as the payload ascends into the Earth's atmosphere
By using data from the SSS of the suns spectrum, analyze the atmosphere at different altitudes and determine where certain gases exist in the atmosphere.

3. Benefits to NASA:
The information found by the SSS payload will be shared on the FSI website and presented to a large group of people.
With the information found the project will show what elements are in the atmosphere and at what elevation those elements can be found.
Data obtained by the SSS flight can be compared to similar research conducted in the past to see how the atmosphere has changed

4. Benefits to NASA:
Having a better understanding of the composition of our atmosphere provides great opportunities for scientists (such as meteorologists) to conduct atmospheric research
NASA may also be interested in this project,  as a similar probe could be launched to extraterrestrial planets to conduct research on the make-up of a martian atmosphere. The SSS design is ideal, since it is small and light.

Project Start Date: June 16th, 2010

11. Expected Results:
SSS is expected to show that certain frequencies of the sun's ambient light are absorbed by gases that exist in the Earth's atmosphere. As the payload gains altitude, the concentration and composition of these gases should change, and the amount of absorption should change.
SSS is expected to show that the observable spectrum of the sun is more complete  in
 the high atmosphere than it is on the Earth's surface.

12. Expected Results:
The film will show the Fraunhofer lines as shown below.
The Fraunhofer lines can be used to determine the chemical make-up of the atmosphere.

13. Level of Readiness:
All subsystems have been constructed and are ready for integration into the box
Testing will be conducted soon after payload integration
