Nike Smoke

The Nike Smoke was a sounding rocket, part of a research project on the behavior of the horizontal winds in the upper atmosphere, developed by NASA in the 1960s based on the Nike booster. The goal was to obtain more accurate data on the behavior of these winds in order to guide the design of new vehicles particularly the Saturn family of vehicles. Nike Smoke used the release of titanium tetrachloride at altitude to create a smoke trail at altitude. The release created a white smoke trail which when photographed from two cameras situated 10–12 miles from the launch site and 90 degrees apart. Comparison of the photographs allowed winds aloft to be calculated in both direction and velocity.
