The Mini-Sniffer was a remotely controlled, propeller-driven vehicle developed at NASA Dryden Research Center (now Armstrong) to sample the upper atmosphere for pollution. The Mini-Sniffer represents one of the earliest attempts by NASA to monitor the earth's atmosphere at high altitudes and was also considered for planetary atmospheric sampling flights over Mars. There were three Mini-Sniffers built. The original Mini-Sniffer was propelled by a small air-breathing engine, while a later version employed a non-airbreathing hydrazine engine for higher altitude capabilities. A large propeller was also employed because of its effectiveness in the thin upper atmosphere.
