1. An apparatus for measuring the electric field in the atmosphere comprising:

  • A. self-propelled rocket capable of being propelled through the atmosphere, B. an elongated probe carried by said rocket constructed of 1/16 inch diameter tungsten steel rod and having a point being sharpened at a 10* angle, C. fins carried by said vehicle spaced a predetermined distance from said elongated probe, D. an electrical circuit connecting said elongated probe and at least one of said fins, E. a high ohm resistor coupled in said electrical circuit between said, elongated probe and said one of said fins, and F. a relaxation oscillator coupled in said circuit for generating a chain of pulse having a frequency proportional to the difference in voltage at, said elongated probe and said one of said fins, whereby the frequency of said chain of pulses is proportional to the electric field through which said vehicle is traveling.
