Project Definition
Goal
Our project goal is to design a descent probe for NASA that will maintain
structural, aerodynamic, and thermal integrity from 100,000 feet to the
surface, and survive impact. The team will design, build, test, and
implement a data acquisition and data storage system. All data will be time-tagged, buffered, and stored in format
suitable for telemetry to ground. The team will use the data collected
to "reconstruct the atmosphere" -- creating a pressure and temperature
profile of the atmosphere for a given altitude.
