Mission Overview
• Analyze the world at high altitude because, due to climate changes
on the Earth, humans may need to live in different environmental
conditions.
• The viability of life sustaining environments in different atmospheric
conditions
• Six ultra-violet photodiodes, one on each face of the satellite.
• Methane gas sensor and the carbon monoxide sensor will be
embedded onto the top of the satellite.
• Dangerous levels of methane and carbon monoxide, and ultraviolet
rays will be determined prior to the launching of the satellite.
Following the recovery of the satellite, the data will be analyzed to
determine if the dangerous levels for each sensor was reached.

15 x 15x 15cm cube
¾ inch insulation on all internal sides
6 UV photodiodes on each face
1 Methane gas sensor on top
1 Carbon monoxide sensor on top
Parts
– Foam Core, AVR microcontroller, digital camera, resistor
heater, HOBO, insulation, CO sensor/module, CH4
sensor/module, 8 UV photodiodes, tubing, wires, aluminum
tape, 9V batteries, aluminum tubing, circuit board,
– UV photodiodes in aluminum tubes
– Gas sensors embedded in foam core
– Camera positioned horizontally to look out of one face, Plexiglas
covering opening to seal, anti-fog on Plexiglas
– All hardware secured inside of cube with Velcro, hot glue
How it works:
•AVR programmed
to turn on gas
sensor heaters,
camera, heater
•Output
•Programmed to
collect data from
UV, gas sensors,
temperature,
pressure, and X
and Y
accelerometer.
•Input
•Take data
every 20
milliseconds
Differences between proposal
and final product:
•Dropped humidity sensor
•Budget problems
•Dimension Change
•Smaller, more compact and greater heater
efficiency
•UV sensors wired in series instead of parallel
•Ensures data from any face of the cube
•Used Velcro to secure components instead of just hot
glue
•Plexiglas window for camera
•Change of team positions/specialties
•Lost a team member
Results and Analysis
UV sensor data on ground
•Spike in data when exposed to UV light
•1.1 to 1.18
•Fluctuating from 1.16 to 1.19 because cube was being rotated and
different amounts of UV light were being detected
•Dropped when UV source removed
Methane Gas Sensor Ground Data
•When exposed to the pre-calibrated level of methane, alarm is triggered
causing voltage to jump from about 0 to approximately 4 V.
•Used propane tank
•Singular trigger
•If gas level not reached, no jump in voltage would be recorded.

•Sensor was turned on when the gas was already present, causing the
voltage to start at 4V.
•Car exhaust used to calibrate, approximately 7000ppm.
•When moved away from source, alarm was no longer triggered and voltage
dropped to about 0.

Sample Number
•Constant
•Temperature readings not correct
HOBO Data
•Turned on at 4:26 AM, not correct
•Turned off at 8:07 AM
•At 8:05:
• temperature changed from 71.77°F to 71.08°F
•Dew point changed from 4.6 to 4.5
•Not a big enough change
•At 8:07, very last reading, everything went back to
original values except secondary temperature
•The relative humidity stayed the same through the
entire time recording data
•Doesn’t seem that any of the data collected from HOBO
is accurate

Flight Recap
•At launch:
•Both red and green lights were on
•Power to board
•Camera did not deploy
•Gas sensor heaters did not get warm
•At recovery:
•Camera still not deployed
•Gas sensor heaters not warm
•Opened Cube:
•All wires intact
•Solid LED on AVR
•Not armed
•Heater not warm
Failure Analysis
•Data retrieval:
•Status was partially armed
•Verifies that it was armed prior to launch, then turned on
•If not armed, status would have been in “safe mode”
meaning disarmed
•Switches were turned on in the correct order
•If not, status would have been armed
•Approximately 7.16 seconds of data taken
•359 data points
•Last data point was 0
•If there had been no data, all points would read 5
•No change in X or Y
•Stationary when turned on
•Pressure and temperature constant
•On ground when turned on
•Not able to repeat failure
•Everything worked during post-launch with no additional changes

Conclusions
 We suspect between the time that we
armed the board and the time of launch,
the satellite was turned on and turned
off, therefore disarming the board and
not allowing any data to be collected
during the flight.
Expected Data
•Increase in UV
•CO detected
•CH4 not detected
Conclusions Continued…
• Discovered that we could use what little
data we collected in order to find out what
went wrong with our satellite.
• While we did not get data from the flight,
our ground data is accurate and using
research we can predict what the results
should have been.
Lessons Learned
• We should have…
• Found one focus instead of trying to take on
several experiments
• Focused more on programming earlier
• Divided tasks earlier
• To get different results…
• Removed the latch from the programming so
that it would stay armed
Ready to Fly Again
• No special storage conditions, but there
should be care taken when handling the
satellite.
• To activate payload:
– Prior to flight replace camera, heater, and
AVR batteries
– Arm payload
– Flip power and then G-switch
– Make sure red and green LEDs are on
– Make sure LED on AVR is blinking
– Camera should deploy when turned on

Semester
– Choose a simple mission objective and stick
with it.
– Start as early as possible and always be
aware of deadlines.
– Don’t be afraid to ask EVERYONE and
ANYONE for help- they will help you!
– Don’t be afraid to bribe for help (i.e. cookies)
– Divide tasks and conquer ASAP!
– If have team issues, tell your team…don’t
bottle up your feelings and have an awkward
session about it later.
