Conclusion.
So, in the first section of my essay I considered how vehicles are propelled into space, the energy they use, the trajectory they follow, the design requirements of different kinds of missions. Besides this I outlined the very special human problems encountered by the space traveler in the second section. The third section both relates the fascinating history of spaceflight, from ideas expressed in early writings to the first actual flights, and provides a brief overview of subsequent developments. The fourth section is devoted to uncrewed scientific spaceflights and their description. Crewed scientific spaceflights are regarded in the fifth section of the essay. The sixth section deals with future plans and ideals for exploration of the solar system and the whole universe. Thus, I described all the main component parts of the concept "space exploration", the task for us and for the future generations, for our children and grandchildren, for all those humanities who cares for their future, because one day the exploration of space, the advance of human and robotic capabilities, the development of breakthrough technologies that will enable long-distance high-speed human spaceflights will probably become the only chance for people to survive. Of course, it does not mean that this day will happen tomorrow, but the earlier we brood over the problem, the earlier we will find the solutions to it.
