"One small step for men, one giant leap for mankind"...these are the words with which Armstrong conquered the Moon with Apollo 11 on the 21st of July 1969. This happened in a period of a great ideological war between USA and the USSR, and even though USSR send first Gagarin into space, basically winning the space race, USA sent the first man, filmed it and promoted it through a good PR campaign, which left the Russians in the shadow.
40 years after that, mankind continues to be dazzled by the Universe and its wonders. Recently I read an article about the existence of another 361 to 38000 civilizations in our galaxy only. The human imagination is extremely rich and we always wanted to discover these aliens, which in movies are either bad and ugly or good and sweet, they come in peace or to conquer us...Be it either, the sky for us has always been a wonder and it has been used both by religion and pagan rituals. God is somewhere in the sky, Jesus was born under a star, as well as, our life is guided by zodiacal signs reflected by planets or even ancient depiction of drawings showing the existence of some creatures coming from above. This is Scientology's favorite topic, so in case anyone would know anything...it should be them.
A problem in this case would if humans could procreate in space. A smart article says that: "sex in space is human sexual activity in weightless and extreme environments of space. The topic also includes conception and pregnancy in off-Earth environments. The topic has been hotly disputed to clarify its potential impact on human beings in the isolated, confined, and hazardous environment of space. Experts consider humanity's expansion into space crucial to survival, though it was considered taboo for decades of space faring exploration history. As of 2009, with NASA planning long-term missions for lunar settlements with goals to explore and colonize space, the topic has taken its respected place in life sciences. Scientist Stephen Hawking publicly concurred in 2007 that possibly human survival itself will depend on successfully contending with the extreme environments of space. In zero gravity there is no natural convection to carry away body heat and bodily fluids tend to pool around the body. The sweat from sexual activity could pool as floating droplets. Although zero gravity is a boon for saggy body parts, males might notice a "slight decrease" in penis size due to the lower blood pressure that humans experience in microgravity..."
