Detection and study of microbial population in upper atmosphere - simulated high altitude sampling with electrostatic precipitator
Observing diurnal and latitude effects for 10 keV electrons on low altitude, high latitude satellite Injun III using low energy electron detector
Ionospheric electron density studied by separating high altitude probe
Occurrence frequency and intensity of clear air turbulence as function of altitude between 20,000 and 75,000 ft
High altitude water vapor observation by satellite of water vapor line profile, noting feasibility of application
Radar type backscatter from ground to Alouette satellite at HF and 1000 km altitude
Variation of electron spectrum and intensity at low altitudes measured by polar orbiting satellites in 1962 and 1963
Lunar exploration from orbital altitudes, noting aerial photographic and radar map techniques and aims
Horizon-sensing sextant measures the altitude of an orbiting spacecraft without gravitational reference by optically measuring the dip angle to the horizon along a line of sight in each of two planes. The sextant scans over a relatively limited field of view.
Detector for measuring positron-to-electron ratio at balloon altitudes as function of electron energy
Behavior of sonic boom shock wave near sonic cutoff altitude
