Radar beam transmitted along electron lines of the earth's magnetic field extending into the exosphere, first confirmation of theory and work of Roger M. Ganet of the National Bureau of Standards and Henry G. Booker of Cornell University. Echo reflected from the earth successfully received 0.2 of a second later after traveling 37,000 miles, perhaps offering a new tool to study the effect of solar eruptions on the earth's magnetic field and a new long-range surveillance method using radar.
