− | SSI-28 was the 28th launch of the SSI Balloons team and the first launch for the experimental payloads of [[Project_UV]] and [[Project_X]]. It flew 169.8 kilometers over a course of 2.5 hours, reaching an altitude of 24 Kilometers before landing. It was a complete success, querying ultraviolet A and ultraviolet B concentrations in correlation with altitude, and the concentrations of specific gasses at different altitudes, in addition to powering heaters and capturing visuals with a camera. | + | SSI-28 was the 28th launch of the SSI Balloons team and the first launch for the experimental payloads of [[Project UV]] and [[Project X]].

− | This payload utilized a Teensy3.2 instead of an Arduino, allowing faster computations, and more sensor readings at a higher resolution. The teensy measured time, altitude, UV(A) & UV(B) in watts/cm^2, and gas concentrations of Hydrogen, Methane, Carbon Dioxide, Carbon Monoxide, Ozone, and particulate matter. It was also capable of self regulating its temperature, and writing data to an SD card. | + | This payload utilized a Teensy3.2 instead of an Arduino, allowing for better computational power, more memory, and more sensor readings at a higher resolution.
