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.
