Mission overview
Mission Overview

  • Mission Statement: To construct a balloon payload that travels to an altitude of 30km, during ascent the payload will collect data on the intensity of light in both the infrared and visible spectrums.

  • The data would attempt to discover the levels of light at high altitude to provide proof of concept to the notion of a telescope mounted on a high altitude platform.


Rfp compliance
RFP Compliance

  • Construct a payload to test the intensity of infrared light

  • The financial budget had $70.00 to spare

  • Took data from the photometer and stored it on board the payload

  • Implemented the photometer designs provided by Yorke Brown


Final product deviation
Final Product Deviation

  • Only able to fly a photometer designed to collect infrared data.

    • Due to weight constraints

  • Mass budget exceeded due to the science payload.

  • Use of modular sections as opposed to booms and collapsing arm.

  • Use of provided insulation versus Aspen Aerogel insulation.



  • Results and Analysis

    • Sky Brightness at all altitudes found to be at or above

      . 22672 W/m2-sr

    • Results limited by Basic Stamp’s code: only checks saturation of integrating capacitor every .1 seconds

      • Expected lower brightness – on the order of tenths of a second but greater than .1 seconds integration time (between .0251893 and .22672 W/m2-sr)

        • Possible reasons for higher brightness:

          • Lower to ground took data-earth emits a lot of IR

          • Filter allowed in over 50% of light between 610-750 nm

          • Clouds reflecting IR and scattering visible

    • Data taken from 0-13,716 m instead of 0 -30,480 m due to lower than anticipated vertical ascent rate



  • Conclusions:

    • Sky brightness for wavelengths of 560 nm and above, though mostly IR, at altitudes from 0 and 13,716 m is at or below .22672 W/m^2-sr

    • Further experimentation at higher altitudes and with a shorter Basic Stamp time integral is necessary to determine exact sky brightness and fluctuations with altitude


Lessons learned
Lessons Learned

  • Time is your enemy

    • Even when launch is +70 days away

  • This project requires much more time than anticipated

  • The simple designs work the most reliably

    • Do not try to reinvent the wheel

  • Never play the margins, always allot for more data collection than necessary

  • Cooperation is key, and everyone has an opinion

  • Know your strengths and do not try to do what you are not capable of completing

Ready to fly

  • HOBO:

    • Wire was severed to take internal temperature data and humidity.

      • Solution: Procure a new data logger

  • HP Camera:

    • No data was taken on flight and the lithium batteries were leaking after removal from housing.

      • Solution: Replace batteries and run a systems test to insure functionality

  • Batteries:

    • Due to use the batteries for the heating system, timing circuit, photometer, and BASIC Stamp need to be replaced.

      • Solution: Obtain 9 volt (Qty:4), 12 volt (Qty:5)


To those who follow us
To Those Who Follow Us

  • Must meet two times a week

    • Even in the design phase

  • Acoms Razor: the simplest solution tends to be the correct one.

    • A simple design is much easier to implement

  • Glue and tape weigh much more than you may think.

  • Metal is not necessarily the best material to use for this project.

  • Do not try to reinvent the wheel. Be creative, but do not dig yourselves into a hole.

  • “Don’t measure a man’s success by how high he climbs, but how high he bounces when he hits bottom.” -Gen. George S. Patton

    • This will make sense when you pull up to the payloads at 70mph on a dirt road hoping for data.

  • It is pronounced “Professor KAY • LER” not “Professor COAL•ER”

    • The only coal you will encounter is in Rocket Boys
