Quadrupole mass spectrometer was designed for studies of neutral atmospheric composition between 100 and 200 km using rockets; technique of ejecting payload at altitude from evacuated volume to reduce contaminants was developed; daytime O1/O2 current ratio was unity at 118 km and 3.1 at 134 km; nighttime flight yielded O1/O2 current ratios in substantial agreement with daytime flight and extended data to 190 km where ratio was 9.5; on basis of daytime data, mean mol wt of 24.6 is derived at 134.5 km.
