This work is aimed at collecting data and analyzing the requirements for small descent vehicles (SDVs) of the capsule type in the implementation of various scientific programs and industrial applications. The research objects are the schematic-forming features of SDVs, system composition, and stages of work during the development of the vehicle. Additionally, a method for rapid assessment of the mass and volume characteristics of systems based on updated statistical data on modern onboard equipment used in CubeSat format satellites and Earth remote sensing spacecraft is considered. The collected and structured information will form the basis for creating a methodology for designing capsule-type SDVs for scientific and industrial applications and its verification through experimental testing.
