Mission Overview: Determine cooling times for a Shape Memory Alloy (SMA) spring in a near vacuum environment. Use a microcontroller to activate a video camera, and capture video of ascent and descent.

SHOT II / AggieSat1 Connection:Development of Responsive Space Mission (RSM) capabilities The microcontroller on our SHOT II payload mimics the generic control board design for AggieSat1. SHOT II provides us with valuable experience building, programming, and testing this type of electronics and RSM device driver dependent functions. Determining the cooling times of an SMA spring (the main component of the SMA Payload on AggieSat1) to allow for more efficient operations on orbit.

SHOT II Design and Test Details:- Mass = 1.076 kg- Lamp Manufacturing kit, central threaded rod used for structural support and payload attachment purposes.
