rockets
It is concluded that a doubling of the CO2, H2O, or NO content would require per year on the order of 103 to 105 Saturn-type rockets, each injecting 100 tons of exhaust above 100 km.
      
On the other hand, a few hundred small rockets per year, each containing 10 kg of the chemical, would probably double the Na content; similarly, less than two such rockets per year would be expected to double the Li content.
      
A general method for the adjustment of stellar triangulation using photographic observations of artificial satellites, missiles or rockets with stars in the background is suggested.
      
Other auroral investigations except those involving rockets have been largely ignored.
      
The behaviour of radio-frequency probes in a magneto-ionic environment is important in connection with their use for measurement of ionospheric parameters and in the design of aerials for rockets and satellites.
      
Also the detection of ionospheric currents by instrumental rockets has confirmed an essential part of the theory.
      
A PCM telemetry system used on both balloons and rockets to handle scientific data is described including a simple Doppler ranging system that gives location to 1.5 km.
      
In the past several years, X-ray observations of the Sun made from rockets and satellites have demonstrated the existence of high temperature (~20 × 106 - ~100 × 106 K), low density plasmas associated with solar flare phenomena.
      
An investigation of wave-particle interactions and particle dynamics using electron beams injected from sounding rockets
      
Electrons with energy up to 40 kV have been injected into semi-trapped orbits from sounding rockets at Wallops Island, Virginia, and at Fort Churchill, Manitoba, Canada.
      
Recent measurements of precipitating energetic particles and vector magnetic fields from satellites and sounding rockets have verified the existence of geomagnetically-aligned electric currents at high latitudes in the ionosphere and magnetosphere.
      
Observations by different techniques, in terms of detectors aboard balloons, sounding rockets, and polar-orbiting satellites, are reviewed (Sections I).
      
Such ions have also been observed on low latitude rockets and satellites, and oxygen ion precipitation exceeding that of protons has been reported.
      
High-resolution ultraviolet solar observations from sounding rockets and spacelab
      
High spatial (~1″) and temporal (20 s) resolution UV spectroscopy of the Sun has been carried out with a new instrument flown on sounding rockets.
      
The electron and ion beams which have been detected on many rockets and satellites are of particular interest because beam particles carry information about both the ionosphere and the magnetosphere out to the distant tail.
      
Sounding rockets and satellites have discovered a large variety of plasma waves within the Earth's magnetosphere-geospace.
      
The observational evidence concerns mainly auroral emissions in the atmosphere, energetic particles observed from rockets and satellites, VLF waves at high altitudes, magnetospheric cold plasma, and magnetic pulsations detected on the ground.
      
Measurements, ground-based and from rockets, satellites, and spacecraft, and model predictions of atomic, molecular and ionic emissions, are presented and the most important sources are elucidated.
      
These instruments were carried aloft by sounding rockets and made observations lasting only a few minutes at most.
