«Every year hundreds or even thousands of small space crafts are launched into space. Therefore in modern space science the problem of space junk utilization is an issue. The standard way to solve it is to equip space crafts with an engine. This way, while termination of usage period the space crafts will be deorbited and burnt into the atmosphere. This solution is expensive due the cost of engine production. Also when the period of usage comes to an end the engine can be out of service and the space craft can be left on orbit as a space junk. We equipped Mayak with the technology of aerodynamic brake. It helps to deorbit satellite easier and faster. For example deorbiting of Mayak (or another satellite with the same size and weight) could last about three years, while with the brake Mayak will deorbit in a month».
