Curiously two decades later it was the time of the United States if to deny a mission manned joint with the Soviets Mars (SAGAN, 1996). The North Americans had extended to its Mercury program of 1961 the 1963 and during six astronauts they had the same carried through longer flights each time. Its missions were more shy than of the Soviets. While these had kept a man for more than 24 hours in the space already in 1961, the Americans had only obtained fellow creature made in 1963. However, some Soviet missions were nothing more than mere propagandas. In 1962, when they had launched two ships to the space at the same time, one passed the 5 kilometers of the other but this nothing brought of practical beyond the fact of Moscow to be able to vangloriar itself to obtain to keep two ships in orbit at the same time.
In 1963, when the Soviets had placed the first woman in the space, it only effected the same that the men already were carrying through and also its mission nothing brought of practical beyond a study of the feminine organism in the space. Later this woman, Valentina Tereshkova, were married cosmonaut Adrian Nikolayev and its children had been kept in comment during years to know which would be the effect of the space trips of its parents on the organisms of the children (SPACEFACTS, 2010). While the Soviets they carried through these missions that served more to call the attention the public, the North Americans carried through experimental science in the space, submitting its astronauts the diverse examinations and tests and taking them to effect it different maneuvers in orbit (on the other hand first espaonaves Soviet was controlled from the ground, therefore it feared that some cosmonaut could not resist the desire to turn into a desert for the Ocidente with the vehicle).
