SpaceX has designed and developed it for payload transfer to Earth orbit and space. Over the time period of 10 years, Falcon 9 has been launched 85 times, in which 46 launches were able to land. Due to its capability of landing, SpaceX has saved costly parts of the rocket. This rocket uses rocket grade kerosene (RP-1, it is cheaper but less explosion hazardous fuel, which is a highly pure form of kerosene) as its fuel and liquid oxygen as an oxidizer. In 2007, SpaceX started the development of Falcon 9 which was boosted by the funds provided by NASA. F
Have you ever thought why we have not found any advanced intelligent organism yet? Or is there any other type of life form outside our planet Earth? These are the basic questions that come into mind when we talk about Fermi Paradox. Fermi Paradox Fermi paradox is the lack of compatibility or contradiction between the high chances of existence of extraterrestrial civilization in the universe and lack of evidence to find them or communicate with them. This was termed after the name of physicist Enrico Fermi. It casually came in head of Fermi during talk with his colleagues and he asked, "Where is everybody?". Early and Related Theories Before Fermi Enrico, the founding father of modern rocket science Konstantin Eduardovich Tsiolkovsky, a Russian scientist, proposed Zoo hypothesis. In Zoo hypothesis, it is speculated that the extraterrestrial civilization knows about our existence but instead of contacting us, they opt to do observation on us similar to animals in zoo. The ot
