Aspirations to cognition of unknown, building of the new world are major features of human's intellect. This feature shows itself though the engineer's creativity which is the main factor of progress, creation of new world.

Creativity is equivalent to the progress and our community depends on those people, who can foresee and supply the demand for new production and (or) technologies of human activity, especially in the field of aerospace research and development.

Nowadays in the time of world crisis aerospace remote probing of Earth by avia- and space bearers can become one of the quick-growing segments of aerospace industry in the most developed counties, including countries of Euro-Asian region.

There are the most prepared personnel and the most advanced young of Euro-Asian integration in the CIS countries from the time of Soviet Union in this field of services.

Appearance of the new fundamental ideas and super technologies in this segment is regularity but as I mentioned repeatedly, it is required very big coordination both in the CIS and in the world community.

The Earth (our home) can be considered in the optical wavelength range as the giant, thermodynamic open geosystem, sui generis a heat engine which is characterized by processes of matter and energy exchange with surrounding space, including inner parts of our planet. The matter and energy exchange between components of geosystems is the factor of its inner unity - its geostructure.

The Earth and the Sun are exist as the matter - substance which is warmed up to the temperature on the surface Т3 =257 К and Тс =5770 К in the field of relict photon radiation, which corresponds to temperature of deeper cold of Space 2,7 К.

Thermodynamic theory of such heat engine is known and the entropy gain is DЭ = DQ/T, where Q - quantity of heat by temperature Т.

Short-wave thermal radiation which comes to the Earth from the Sun is about Ес =230 вт/м2  and correspond to the Sun surface temperature about Тс =5770К.

Structure and dynamic of processes in the landscape sphere in the surface layers of the Earth depends on quantity of energy which comes to the geosystem.

Evolution and self-organization processes occur in thin layer of Earth's crust which consists of rocks and sedimentary rocks, water and atmosphere.

Evolution and self-organization processes express in geological, atmosphere and biological processes. Evolution and self-organization processes on the Earth take place because of temperature difference (gradient) between the Sun or the Earth core and temperature of the Space.

Nowadays the better aerospace thermal imagers and radiometers have equivalent to noise temperature difference DТЭ = 0,1÷0,3К, that is on two degree more than 8÷15 mm - maximum sizes for this atmospheric window, which conditional on background noises. This is means that information volume of coefficients reflection from different objects is equivalent to eyes information value in illumination on 4 degree less than middle day illumination, which correspond to deep twilight.

By objects observation on the Earth surface in cloudless weather contrast coefficient is sin275° = 0,933.

But for penetration to the depth of geological structures of a landscape the new method of temperature sensitivity rising can be applied - Mukhamedyarov's videothermovision generalization method (MVTGM).

Mukhamedyarov's videothermovision generalization method (MVTGM) based on applied consequences of two lemm- hypotheses, which is raised and used by author from 80 th years of the last:

     thermal radiation remember its origin;

     deep Earth's structure is semitransparent in the optical wavelength range

Essential novelty of MVTGM is in the following. Precedent maps of thermal field of the Earth are based on contact methods of temperature detection in holes using sensors with limit quantity. Therefore getting by this methods temperature distribution is necessary discrete. MVTGM allows to get continuous picture of temperature detection, and this is its mail qualitative difference from contact methods. Practically the effect of uninterrupted probing and Earth density anomaly exposure by depth with appropriate anomalies of temperature field is applied. At this point temperature field is got by using weight function based on three-dimensional pyramid enclosure of the Earth crust thermal radiation in result radiation of surface element.

Suggested method allows searching anomalies of the Earth temperature field with depth, i.e. to define regions of anomalies mass-energy exchange - in different fields of geologic-geophysical layers of the Earth. This is achieved because aerospace digital thermovision images  are processed by suggested method, particular, in the base of three-dimensional pyramid enclosure of the Earth crust thermal radiation in result radiation of surface element.

Full apparatus implementation of MVTGM is possible within the bounds of International project (), realized within the bounds of UNO. in the program of  intergovernmental agreements.

For project realization it is necessary to use in one time geostationary orbit middle and low- orbit satellites and avia-bearers: aircrafts, helicopters, and dirigibles.

Space apparatus in the geostationary orbit has equal circulation period to rotation period of the Earth and plane of orbit is matched to equator plane.

Under-satellite point has its own geographic longitude - working point and zero latitude. B.Ye.Ghertok affirms that there were 240 guided space apparatuses in 2008 on the geostationary orbit, and there will be another 20th in each year.

For international project () realization the following minimal conditions are necessary:

1. Six satellites on geostationary orbit by Earth equator are integrated in two groups by three satellites - apexes of two triangular plains, which conditionally dissect the Earth by equator as . Geometric dimensions and angle position of each triangular plains are defined by laser range finders (precision + 1 mm) and star sensors on satellites (precision 0,5÷1 second of arc.)

2. On big engineering constructions, such as the Great China Wall (length 7300km), bridges, weirs, atomic and thermal power plants theodolite-range finder are settled. They work at the same time by satellite and by reflectors, placed on complicate engineering constructions. At the cost of this creation of global positional system with precision + 1 mm is reached.

3. Highly sensitive radiometric apparatus of visional and thermal range with permission 1440m in thermal (long infrared) and 360m in visible range are set on geostationary orbit satellites. And highly sensitive radiometric apparatus of visional with spatial resolution 70m and thermal range of 140m (capture on area 136° (5H=3500 km)) are set on satellites which working on solar-synchronous orbit H=700 km.

Angle resolution of multispectral thermal imager-radiometer (МТR), which is placed on geostationary orbit Н=35880 кm for penetration to the center of the Earth hN=hT=6377km at N= 225-steps of generalization must be = (p/2)·10-3rad, at that time visible ranges of optic spectrum (zero layer) may have resolution that is better on p/2·10-4 rad.

4 Videothermovision apparatus with spatial resolution from 1 to 120 mm and temperature resolution about ~0,01 К which are set on dirigibles built into global positional system with definition of spatial resolution to precision 1mm are used on the height of 50m to 6000m

Through special integral conversion generalization allows to take temperature sensitivity to (10-5-10-6)К, that leads to the effect of layer-specific (1÷225 layers) penetration to the Earth's depth and uninterrupted control of lithosphere plate movements (thickness 25÷35km), which are causes of thickness, tension, and also to more qualitative and quantitative description of engineering constructions and processing station thermodynamic condition.

So it could be synthesize of many videothermovision images of the same object. By comparing it with primary pictures in visible and near infrared range of given object, it could receive on the one "analytic level" mutual disposition of what placed above (under) land and under water on different depths and determine technical condition of engineering constructions in different times of the day and year in static and dynamic.

In the following stage of interpretation of decode images by different fields knowledge specialists: geologists, geophysicist, mechanics - specialists by nondestructive control, the qualitative new information can be received.

Temperature differential (gradient) is sharply changing in the place of destruction of engineering constructions and breaks can happen. These values of thermodynamic temperature changing are very small - about 0,001÷0,00001К, but by MVTGM method it is possible to reveal and track it. Remote tracking of such small changing of temperatures opens new page of anthropogenic catastrophes and natural disasters forecast.

At that temperatures and high pressures deep structures of the Earth from centre  to depths h≈2000km practically are optically transparent for ultraviolet, visible and close infrared own radiation. From three components conducted thermal conduction, convection and radiant heat exchange (radiation), the last plays the main role in the Earth thermodynamics.

As for the following layers of the Earth close by surface (from 2000 кm to Earth surface): the first layer h1 moves the spectrum of its own radiation to remote infrared spectrum to the window of atmo-sphere transparency and geological environments becomes environment.

By using of МВТГМ and experimental data of the future system it could be determined what exactly temperature is in the lower mantle of the Earth and what is its physical structure by radiation capability by wavelength, and the most important is to track efficiently and forecast all natural disaster and anthropogenic catastrophes of our home - the Earth.
