MAI Scientists proffered the creation of ion engine

Russia intends to create an innovative ion engine, which will use atmospheric gases for its operation. MAI specialists have already begun to explore the possibility of creating such a device, RIA VistaNews reported. One of the most promising directions in the development of space industry is considered to be the creation of satellites having a low weight. Their destination is the remote sensing of the planet's surface. Height synchronized with the Sun orbits of these devices will be 300-700 km.

The reduction in height of the orbit increases the effectiveness. But to achieve it scientists need to find a solution to the following problem. By reducing the height of the orbit, the Earth's atmosphere density is greatly increased. The satellite will experience a serious increase in aerodynamic drag.

Electric propulsion is now used to correct the parameters of operating conditions for a given spacecraft factor. Gas xenon is used as a fuel. It belongs to a quite rare category and is expensive. Further, for its allocation the increase of weight and volume of the satellite is needed. It is inefficient for use at lower altitudes.

Russian scientists have proposed a different engine concept for the satellites to be placed on low orbits. It will be able to collect atmospheric gases that are in the environment. These are variety of oxygen and nitrogen. Laboratory sample is already established and tested in conditions simulating outer space at an altitude of 200-250 kilometers.

MAI will have to solve problems with the creation of a space of this type of engine. The first step is to select the cathode which will be the most efficient and capable of working with atmospheric gases differing reactivity.

Terms, during which the idea of a new engine for small satellites can be put into practice, is not divulged.
