Advanced Technologies Experiment (Atex) Spacecraft

Description

The ATEX (Advanced Technologies EXperiment) missions of microspacecraft is technically (on a level of a range of sub-systems and preliminary design stage) developed for conducting of a wide spectrum of investigation/research works in LEO, MEO and radiation/van Allen belts of the Earth. The main investigations and experiments are concerned to electric-jet propulsions which are placed on the opposite sides of the spacecraft and have direct power supply from solar panels.

Other experiments are linked with re-searches of devices capacity for work in hard conditions of the radiation belts, its degradation, measurement of electric field near the spacecraft and charged particles analysis, construction materials. The space-craft is based on the Yuzhnoye’s platform MS-2 bus and intensified protection of main sub-system devices.

Advanced technologies concept has been proposed to investigate the potentialities of small and big satellite injection from LEO to GEO including deep missions over van Allen belts using for launch to LEO the light launch vehicles (DNIEPR, ROCKOT, MINO-TAVRE, etc.). The approach will allow to reduce cost for the launches to high orbits of satellites and space-crafts.

Innovative Aspect and Main Advantages

The ATEX MicroSpacecraft is designed for conducting of investigations with two micro Stationary Plasma Propulsions (SPP) of class SPP-20. The main investigations will be conducting in:

  • studies of dynamic and resource potentialities of the SPPs in direct power supply (without usage of batteries) from the spacecraft photo-elements of solar panels in LEO, MEO and van Allen belts. The investigations will assist to many scientists to learn the potentialities of the SPPs, advanced materials for spacecraft design and types of devices protection;
  • taking into account increasing of interest to deep space and Lunar missions, it will be useful to reduce the cost of the spacecraft launches using light space launch vehicles and its services for injection to LEO and then by EJP to the targets;
  • strong interest to the experiments into radia-tion areas of the Earth: electric field and plasma analysis near a spacecraft, level of degradation of solar batteries in the areas, measurements of ultraviolet rays and charged particles.

The ATEX Conceptual Project and Mission Analysis of the spacecraft were developed with participation of International Team: Zhukovskiy Kharkiv National Aerospace University (ZhKhNU “KhAI”), Yuzhnoye SDO and CNRS (France).
