Professor José Maza, a well-known Chilean astronomer and science communicator, winner of the National Prize for Exact Sciences in 1999, explained why humans have not returned to the Moon since NASA's Apollo missions in the 1960s and 1970s. During his speech at País ADN, the doctor in Astronomy stressed that the main reason is the high economic cost of space missions. “Returning to the Moon is extremely expensive. At the time, the United States spent 3.5% of its Gross Domestic Product (GDP) to get there, which was equivalent to about 10 billion dollars a year,” explained Maza. “The cost of a Saturn V rocket, which was used for the Apollo missions, was 1 billion dollars, and it was only used once. It was an enormous amount that the United States decided to spend mainly for political reasons during the Cold War,” he added. According to Maza, lunar missions were largely a competition with the Soviet Union, which was leading the space race at the time. “Kennedy was the one who pushed the idea of reaching the Moon before the end of the 1960s, in an effort to demonstrate the technological and political supremacy of the United States over the Soviets,” he said. The future... The astronomer also mentioned that after the first moon landing in 1969, and after six other successful missions, NASA scientists wondered what else they could learn. “We had already collected 300 kilos of samples from six different places on the Moon. The consensus was that a seventh mission would not contribute much more to scientific knowledge. In addition, with the same budget for a trip to the Moon, several robotic probes could be sent to explore other places in the solar system,” he said. Finally, the professor reflected on the current competition for space exploration, this time with China as the protagonist. “Now the Chinese want to reach the Moon, and it is likely that they will do so soon. Meanwhile, the United States has plans with the Artemis project to return to the satellite in the coming years. The real competition, however, is moving towards Mars,” he concluded. #chile #radioadn #profesormaza #astronomy #science
