Observations of the far UV nightglow have been made in 150 to 440, 150 to 800, 730 to 1080, and 1130 to 1500 A bands. Night sky radiations identified as 304, 1026, and 1216 A were observed. In addition, the 730- to 1080-A photometer observed an unide

The ambient positive-ion composition of the upper atmosphere in the range 8 to 49 atomic mass units (AMU) was measured between 93 and 219 km by means of a Bennett radio-frequency mass spectrometer. The experiment was flown in the Navy Viking 10 rocke

Two independent sets of ionic composition data have been made during the recent solar minimum period. One set, obtained in early 1963, covers the 90–240 km region; the other, obtained in early 1964, covers the 400–1200 km region. These data may b

Evidence has been found that the earth is immersed in a large volume of glowing helium ions. This ionic glow, at 304 angstroms, is similar to the geocoronal hydrogen glow in that it extends to very high altitudes, but it is unique in that it is large

A rocket-borne photometer has detected far ultraviolet night glow radiations that are identified as Lyman-beta (HI 1026 angstroms), and the helium lines at 304 or 584 angstroms, or at both. At an altitude of 227 kilometers the measured intensity for

The ambient positive and negative ion composition in the mass range 5 to 60 atomic mass units was measured between 93 and 131 km by two Bennett radiofrequency mass spectrometers.1 The spectrometers were flown in Aerobee rocket NRL No. 24 at White San
