Project summaryThe rocket-space activity is being kept in Kazakhstan for 50 years. During that period thousands of carrier rockets (CR) of “Soyuz” and “Proton” types had been launched. Man-caused influence of “Baykonour” start complex and Earth atmosphere disturbance caused by CR become apparent in different forms of atmosphere pollution by combustion products and in thermal action over atmosphere and underline surface pollution with propellant components and its sub products. No doubt that meteorological parameters play a very important role in transfer and precipitation of different pollutants descended from working rocket or used stage.
It is obvious that carrier rockets influence region weather and local climate. However it is difficult to expect any statically significant result due to energy estimates only and nowadays there are no data proving such connection. That is why such task was not paid much attention in scientific investigations. Nevertheless CR launches influence on weather in the cosmodrome region, especially in the Aral region, known due to insiccation of the Aral Sea, can’t be excluded absolutely. This phenomenon needs investigation to prove or refute opinion of nearby settlements about launch affection on weather.
Chemical atmospheric pollution by CR launching is determined by toxic propellant components and combustion and decay products during regular and irregular rejection, floods, and stage falls which contain propellant remains on earth surface. Physical CR launch affect is determined by warm, noise and other effects formation and isolation.
One of main objects of investigation is stratospheric ozone. Propellant combustion products like chlorine, nitrogen and hydrogen compounds interacting with it are related to minor atmospheric constituents. Stratospheric ozone is destroyed under photochemical reactions with water vapor, output during propellant combustion in liquid-propellant rockets as well as during reactions with nitrogen oxides formed of nitrogen and oxygen at high temperatures in rocket jets and chlorine and hydrogen chloride which are products of solid-rocket propellant combustion.
Maximum ozone layer exhaustion occurs along the rocket trajectory. In the rocket track, which diameter is several hundreds meters, ozone is fully destroyed. However the estimation of such decrease consequences for biologically active ultra-violet radiation at earth surface is needed.
Another aspect of injurious effect of rocket-space activity is environment pollution with propellant. In ecological aspect the most dangerous scenario of propellant components (PC) rejection is formation of mixed water and propellant drops falling down with precipitations.
When liquid propellant components fall into atmosphere the cloud is formed which contains both gas and condensed substances. The characteristics of last one are appreciably dependent on rejection scenario and air parameters. Dispersity is possibly connected with explosion energy and thermo-mechanical ambient air influence when PC mass splitting occurs under the influence of approach airflow or due to cavity formation inside liquid mass with PC vapor pressure excluding atmospheric one.
The time of derived components ingress in the atmospheric boundary layer is estimated at 2-4 hours (Granberg I.G., 2001). But behavior of other propellant components, asymmetric dimetilhydrazin in particular, is still not investigated. New investigations are needed for PC interaction with atmospheric vapor study and development of model and program module adaptation, taking of joined experiment for model validation with groups working on the ground and plane lidar sounding which ca give most exact information about cloud trajectory and admixtures concentration in it.
Complex investigation of carrier rockets launch from “Baykonour” cosmodrome influence on atmosphere and environment on the territory of Kazakhstan Republic, nearby to rocket-space complex “Baykonour” regions and stages fall fields for development of methods for estimation of CR influence and prediction and abatement of injurious effects of such influence.
