SSI-30 was the 30th launch of the SSI Balloons team and the second launch for the experimental payloads of [[Project UV]], [[Project Sol]], and [[Project X]]. It flew 71.30 kilometers over a course of 3 hours, reaching an altitude of 23.59581 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, this time with amplified analog values, and implementing dynamic solar tracking and current data logging, in addition to powering heaters and capturing visuals with a camera.
== Pre-Launch ==
[[File:SSI_30_02.jpg | left | thumb | <center> The team</center>]]
SSI-30 was part of a combined experimental balloon launch with [[Project UV]], [[Project Sol]], and [[Project X]] designed to provide preliminary data for these research projects.
== Payload Specifications ==
[[File:SSI_30_05.jpg | right | thumb| <center> The Teensy electronics </center>]]
This payload utilized a Teensy3.2, operational amplifiers, a DC motor, and an H bridge. The teensy measured time, altitude, UV(A) & UV(B) in watts/cm^2, solar luminosity and generated current and voltage, 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.
== Launch site ==

SSI-30 was launched from a park near Modesto, CA at 11:16AM. The team left campus at 5:30AM, had to correct the current sensor wiring on site, and returned to campus at 11:00AM.

SSI-30 was outfitted with a balloon with about .5 net Kg of lift. Due to unforeseen circumstances [[SSI-29]] was also attached to the same balloon. In addition, due to changing winds, the balloon changed direction, lowering the net linear ground track, traveling 71 Kilometers.
== Debriefing ==
SSI-30 was a success and fulfilled all of the initial goals set out by the team.
*Successful data collection and logging of [[Project UV]] data
*Successful data collection and logging of [[Project Sol]] data
*Successful data collection and logging of [[Project X]] data
*Successful implementation of a heater control mechanism
*Successful capture of arial footage
*Successful landing and recovery
