In this research, the structure of the probes sent to other planets is first investigated and the common structures are introduced. In the following, the system design process of the Armita probe, which was prepared for the first national competition of the probe robot (Iran Space Research Institute), will be discussed. Armita team has won the first place in the first phase of the competition in 1401. The probe design process is based on the ECSS standard and is presented briefly, which includes the compilation and extraction of the requirements document, function-performance tree, product tree and finally the conceptual design of the sub-systems to achieve the intended mission. Based on the extracted results, the Armita probe with a mass of 6.9 kg and geometric dimensions of 48 x 38 x 36 cm with a total energy consumption of 112 amp hours will be able to perform the intended mission and satisfy all technical, dimensional and mass requirements well. shows

Stress environment of space flights including hypergravity and microgravity effect cell functions and processes. We studied effect of hypergravity and flight stress on function, death, growth and cellular damage of five cell lines including human vascular endothelial cells, rat bone marrow stromal cells, mouse embryonic fibroblast cells, PC12 cells and pancreas islands in Biological payload of 3th sounding rocket by NO, LDH, MTT and insulin assay kits. Our results indicated that effect of hypergravity increase significantly cellular death and NO secretion but we found no changes in insulin secretion and pancreas function.
