Science Objective Our goal is to learn if IR radiation is dependent on temperature or altitude in the upper atmosphere. We are also going to study temperature as a function of altitude during ascent.
Payload Design The payload will be constructed out of a BASIC Stamp and be connected to an infrared sensor and a thermistor. The sensors will be interfaced to the BASIC Stamp through an ADC channel. A timing chip will also be included to coordinate the data with GPS data taken by the balloon systems. There will be a camera facing the side of the box that will take pictures at certain intervals.
Fabrication and Testing The first step will be to design the circuitry for the sensors and chips. While waiting for the parts to be delivered over the next several weeks, we will finish mounting all the basic components of the circuit. When the ADC, RTC, and sensors arrive, we will begin testing with an oscilloscope before we mount the chips. The final test will to suspend the payload above a surface and determine if the readings taken match the actual data.

Fabrication Test List (cont.) –RTC Attach power source Send command to begin transmitting time Use Basic Stamp to interpret signal
Mission Operations The payload will be launched and tracked from the ground. Upon recovery the EEPROM will be downloaded and the data converted to temperatures and light intensities to determine if a correlation exists between the two.

Data Analysis Temperature and IR light intensity will be measured every ten seconds during the flight. All data will be stored on board and recovered with the payload. Software needs to be developed to convert voltages from the sensors to temperature and IR light intensity.
