Carrying out biological experiments in space conditions is of great interest because this kind of investigations are considered to be the part of solving the life origin problem both on Earth and in the whole Universe. Search for the non-Earth life is closely connected with investigation of conformities of biologically significant substances (BSS) appearance on different cosmic objects. The presence of aminoacids, nitrogen bases carbohydrogens and other bioorganic compounds in meteorites, comets and intraterrestrial milieu witnesses that abiogenese reactions occur in space. Solar electromagnetic and corpuscular radiation, galaxy space radiation, extreme temperatures and the other kinds of radiation could produce energy for BSS synthesis. We have used the single source of energy for our abiogenic reactions in laboratory experiments. However, in natural space conditions several sources of energy act simultaneously. Despite the grate number of papers concerning BSS synthesis in laboratory experiments, investigation of natural open space energy sources action on BSS abiogenesis was described only in our works. The purpose of this work is to investigate the possibilities of uridine nucleotides abiogenic synthesis under the action of summarized open space energy sources. Satellite's surface was taken as a model of surface of small Solar system bodies such as comets, asteroids and interplanetary dust particles, where abiogenic reactions could take place.
