Question: How can we search for caves on Mars? Problem: Cave detection has traditionally been geared towards military applications rather than towards geological research, so we had to come up with a better method of detection. NASA Langley Research Center had developed an infrasonic detector the size of a basketball while most infrasonic sensors are over 100 feet in diameter. The sensor was given to Extreme Endeavors to determine if air variation and pressure differentials could create an infrasonic signature. Extreme Endeavors determined that caves do produce an infrasonic signature, and further investigation found that the signature is based on the opening and depth of cave. We found that Infrasonics could be used for many tasks such as: measuring human gait, identification of a particular vehicle in motion, wind turbine noise, and forest fire detection. Our research led us to a new question: If we can use an infrasonic sensor to detect caves, could bats possibly use the same concept to find their caves?
