“…This payload, flown from Wallops Island, Virginia, on November 15, 1960, provided the first successful U.S. measurement of this type at a location other than Fort Churchill, Canada. A somewhat similar series of flights was made in the middle latitudes of the USSR by Soviet scientists in 1959, 1960, a•d 1961 [Pokhunkov, 1960[Pokhunkov, , 1962[Pokhunkov, , 1963aIstomin and Pokhunkov, 1963]. INSTRUMENTATION The rocket NASA 4.14 was instrumented by the Goddard Space Flight Center to obtain, from 100 km to the peak of flight, information about the neutral particles and positive ions in the earth's atmosphere.…”

The diffusive separation of argon and nitrogen was measured by means of a Bennett radio frequency mass spectrometer carried on an Aerobee 150A rocket (NASA 4.14) launched at 1141 EST, November 15, 1960. The primary purpose of the spectrometer measurements was to obtain temperate latitude diffusive separation data to compare with those measurements obtained in the arctic (Fort Churchill, Canada) during the International Geophysical Year. The results indicate that diffusive separation occurred above about 110 km and that the altitude profile of the A/N2 ratio is similar to that obtained during the two night flights in the arctic atmosphere.
