Payload Pre-flight Testing
Testing
• Drop Box
• Results were good
• Sturdy construction
• Circuit tests
• Connections were good, except one
• That connection was fixed by Dr. Flaten
• Heater Test
• Functions
• Camera Test
• Operational
• IMU
• Tested data recording capabilities
• Passed
Additional Testing
• Cold soak test
• Made sure that payload can handle extreme temperature
• Passed
• Day-in-the-life Weather test
• Attempt to alter weather station data to test function
• Passed
• Yank Test
• Make sure that the box stays together
• Passed
Results of Testing
Our Payload was Ready to Go!
(w/ few modifications)
Escape of the Zombicarus:
… or Flight Day
Pre-Flight Checks
Filling the Balloon
Release
Flight Day
• Status of the payload after the recovery was
basically the same. Minor scratches from the tree
landing. Landed roughly 25-30 feet in the air in a
tree. Retrieved with bolo.
• Payload was still securely sealed and all the
instruments seemed to be working inside.
• Disconnected all batteries and turned off IMU
Science Results
Expected Science Results
• HOBO + Weather Station (WS)
• Sensors:
•
•
•
•
Internal temperature (HOBO)
External temperature (HOBO + WS)
Relative Humidity (HOBO)
Pressure (WS)
• These sensors will record data similar to Paul
Verhage’s
Paul Verhage’s HOBO + WS data
Expected Science Results
• Optical Experiment
• Solar Observation
• Our hypothesis is:
• It will not be cost effective
• It may produce quality images of the sun that may be difficult to
recreate on ground
• Whether or not we get a good glimpse of the sun is arguable
• IMU
• Acceleration and movement tracking test
• Our hypothesis:
• After launch there will be little change
• Post-burst will be violent, and we will be able to track it through the
IMU

Conclusions
• External Temperature vs. Time
Temperature dropped to about -50 degrees
Celsius until about the 50 minute mark, then
the payload entered part of the atmosphere
where it started heating up to about -15
degrees Celsius, which at that point was close
to burst, and following the burst the
temperature rapidly fell to the lowest of the
flight of -55 degrees Celsius.
Conclusions
• Relative Humidity vs. Altitude
According the graph, as altitude increased, humidity decreased,
to as low at 5% around the 80,000 foot mark.
• Pressure vs. Altitude
As altitude increases the pressure decreases
• Solar Observation: Did not exactly work, need
a better way of blocking out the sun.
• IMU results will come later
Conclusions
• Change anything about payload to fly again?
• Yes, better strategy to block out the sun with our HD video
camera to get better results.
• Project Successes:
• Pumpkin design, which ultimately boosts morale of the
team, which in turn makes them happy, thus, makes them
work better.
• Other successes:
• Payload stayed intact, all instruments functioned properly.
• Final Project Successfulness:
• Relatively successful
Words of Wisdom
• Don’t drink too much water on the chase, you
never know when you are going to stop.
• Think BIG
• If you assume, you make an a** out of “u”
and “me”
• If you think it might be cold, then it probably
will be
