Rockets today hold many uses whether they are used to launch astronauts into space or launch warheads to distant countries. Without rockets these things would not be possible with today’s technology. More uses for rockets would be putting satellites into space, launching specialized equipment for meteorology, or atmospheric research, they can be used to propel heavy airplanes at take off or as a means to launch gliders. The possibilities are endless and the role that rockets play is constantly being changed and advanced to fit new technology. For this paper the use of rockets as a means of gathering atmospheric samples will be explored. (Microsoft Encarta)
Sounding Rockets
Rockets that are used to take atmospheric samples are called sounding rockets or meteorological rockets. The rockets get their name from the nautical term “to sound,” which means to take measurements. These rockets are so useful because they measure in between the operating range for high altitude balloons and satellites. ... htm) The rockets for these missions are low cost and generally reliable and can be prepared in a very short amount of time. ...
Air/ Atmospheric Sampling
“There are three types of contaminates according to their physical properties that are generally sampled and could possibly be sampled by an amateur rocket: particulates, gases, and vapors. ... An aerosol, a dispersion of solid or liquid particles of microscopic size, in air. Dust a solid particulate capable of temporary suspension in air, usually derived from larger masses through the use of physical force. ... Mist a dispersion in air of liquid droplets usually large enough to be seen by the naked eye. ... The behavior of bioaerosols is governed by the principles of gravitation, electromagnetism, turbulence and diffusion. ... Air serves as a mode of transport for the dispersal of bioaerosols from one location to another. Composition and concentrations of microbes in the bioaerosol vary with the source and the dispersal in the air until deposition. ... Microorganisms released into the air are often single units (spores) or associated with particles in the range of 0. ... Transport and ultimate settling of a bioaerosol are affected by its physical properties (size, density, shape) and environmental parameters (air currents, humidity, temperature).
