Back in 1973, the total cost of Apollo 11 mission was $25.4 billion. The most expensive parts of this mission, were Apollo spacecrafts. A single Saturn V launch can cost up to almost $400 million, which was really big amount of money in that time. An amazing fact with the rockets, was that, during the takeoff each one of the burnt 3 tons of fuel per second. In 2009, NASA tried to figure out once again what was the amount of cost for the project that occurred almost a half century ago. They came up with the number of $200 billion in today’s money. Compared to today’s cost of modern space travel, where some companies charge $130 million to launch a spacecraft to the international space station. From this example we can really get a better picture of how important that mission was for humanity. Nowadays, people are starting to ask themselves, whether it was worth or not. In 1966, NASA’s budget was at its peak, and it was 4.4% of the federal budget. Between 1975 and 2000, the budget was around 1%. Since the mid 90s it has slowly declined to 0.5%. This was one of the most important research project in the history of humanity. After that, every further action was much easier. Now we are using it as much as we can to gather the information which one day can help us to move out our population from the earth that we know.
