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:
o
Analyze the atmosphere at different altitudes
o
Determine where certain gases exist in the
atmosphere
Benefits to NASA:
• The information found
the project will show what
elements exist 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
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 an alien
atmosphere. The SSS
design is ideal, since it is
small, cheap, and light.

• Project Start Date:
June 16th, 2010
Expected Results:
• SSS is expected to show that certain frequencies of
the sun's ambient light are absorbed by gasses that
exist in the Earth's atmosphere. As the payload
gains altitude, the concentration and composition of
these gasses 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.
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.
Testing:
Cold Test Results:
Camera and heater containment system were placed in an environment
cooled to about -80℃ using Liquid Nitrogen
Testing:
Spectral Detection and Focus Test Results (Camera):
The original camera used to record the spectrum produced by the
spectroscope had limited resolution and no means of appropriately
magnifying the image (limited to 4x digital zoom).
New camera does not require the use of extra lenses to magnify the
image produced by the spectroscope, as it contains its own “5x optical
zoom”.
