Update of the development of a low cost data acquisition system for the Space Shuttle solid rocket booster program

The Space Shuttle has been flying for seventeen years and current NASA plans show it flying for many more years. To support the current and future shuttle flight schedule, portions of the shuttle are being upgraded. One of the areas being upgraded is the avionics on the solid rocket boosters (SRB's). To develop reliable avionics hardware, the environments that they encounter during ascent, descent and water impact must be known. Past environmental data collected did not provide the high fidelity data that is required to fabricate new avionics hardware. This paper summarizes the effort to measure the SRB environments via a commercial off the shelf data acquisition system.
