SSI-24 Orion was one of three balloons launched during fall quarter, 2015. It consisted of an almost all-freshman team dedicated to creating a scientifically power yet aesthetically beautiful payload. Ultimately, Orion represented a resounding success in its use of sensors, logging of data, power management, use of solar energy to charge its batteries, demonstration of wifi transmissions, and creation of a visually refined payload.

The total ground track was 121.21 miles, and the top speed reached was 92.44 miles per hour.

SSI-24 also launched the infamous [[SSI-Guy | SSGuy]] or SSI-Guy.

SSI-24 used the SPOT Nebula for tracking and recovery. See http://habmc.stanfordssi.org/#/app/spot_four. A Phantom 2 UAV was used by members of Orion to video the launch of SSI-23a, 23, 24, and 25.

SSI-24 included both a Raspberry Pi 2B and two Arduino Uno boards. The Raspberry Pi was initially intended to be used to stream live video from the balloon, however, due to issues with the camera board, it was simply used as a wifi access point. The two Arduino boards regulated the sensors onboard the balloon, including a temperature sensor, two heating pads, an SD reader, a GPS, a solar panel, and an accelerometer. Though the group initially intended to use a PIXY camera as well, the PIXY's requirement to be updated with signatures made it difficult to use aboard the balloon.

The second board served a single purpose: dropping three Hershey's chocolate bars at a specified altitude. This was accomplished using the GPS altitude from the first Arduino, which would set a single digital pin to high. This would trigger the second Arduino to swing a servo and release the bars.

Upon landing, SSI-24 was discovered by two passers-by. They kindly brought it to their home and phoned the balloons team, who recovered it soon after.
