1, the beginning of human exploration of the moon:
1957, 10/0 On October 4th, the Soviet Union successfully launched the world's first artificial satellite, Putnik I, marking the first time that mankind entered the space age. This incident aroused the interest of American government and scientists in space exploration.
2, the realization process of human exploration of the moon:
In the following years, the United States and the Soviet Union launched a protracted space race for the leading position in space science and technology. 1961April 12, Soviet astronaut yuri gagarin became the first human to go into space, and he completed a space flight around the earth.
1On July 20th, 969, Apollo spacecraft 1 1 with astronauts neil armstrong and Edward Aldrin successfully landed on the moon, becoming the first man to set foot on the moon. Armstrong said the classic line when he set foot on the surface of the moon: "This is a small step, but it is a big step for me."
This historic moment shocked the world, and the dream of exploring the moon finally came true.
Problems faced by human beings in exploring the moon;
1, cost problem:
Manned space mission needs huge investment, including research and development, test and manufacture of spacecraft, training and support of astronauts, etc. In addition, it is necessary to establish and maintain complex infrastructure and networks to support the implementation of manned space missions.
2, flight safety and astronaut health issues:
Long-term space flight has brought great pressure to astronauts' physical and mental health, such as the influence of microgravity on bones and muscles and the damage of space radiation to DNA. In order to ensure the health and safety of astronauts, we need to further study and improve space flight technology, and carry out long-term health monitoring and care for astronauts.
3, sustainability and environmental protection issues:
The utilization and development of lunar resources should follow the principle of sustainable development to ensure the rational utilization of lunar resources and environmental protection. In addition, the protection of historical sites and scientific values on the moon also needs full attention to avoid unintentional damage to the surface of the moon.
