Recent International Aerospace Congress, which took place in Moscow, covered issues of mitigation of excessive space debris.
      
      Space authorities say that after 2055 steady growth of space debris puts in question further exploration of space by next generations.
      
      Experts warn about additional troubles for space exploration, such as possibility weapon deployment in space; growing traffic of small space ships, which are very hard to control; active space tourism and suborbital flights and etc.
      
      Russia needs development of international regulations of space activities, which meet all international standards.
