To many of you, it's probably given to you as an assignment by your teacher.identify data sources, gather, analyse and present information on the contribution of one of the following to the development of space exploration: Tsiolkovsky, Oberth, Goddard, Esnault-Pelterie, O‘Neill or von Braun
My Physics teacher on the other hand won't, we have to do it ourselves.
I proposed to research von Braun, who worked on V-2 rockets, but they were for military applications, not space exploration.
Which of these people do you find contributed most to space exploration ?
