Since 1959, the former Soviet Union has launched many lunar probes. Lunar 3 probe circled the back of the moon, and the photos it sent back made people see that the back of the moon was really different from the front, and it was devastated by meteorites. Lunar 9 probe made a soft landing on the moon for the first time and brought back the first batch of panoramic photos of the moon. The United States also launched a rover and probe to explore the moon, laying the foundation for manned landing on the moon. During the period of 1998, the lunar explorer made an expedition around the moon, which not only confirmed that there were abundant mineral deposits and helium -3 nuclear substances on the moon, but also found hundreds of millions of tons of frozen water at the moon's poles, which brought good news for human beings to develop the moon.
The Venus probe of the former Soviet Union unveiled the corner of Venus veil. 1989 The Magellan Venus probe launched by the United States drew the first panoramic view of the surface of Venus through the scanning of synthetic aperture radar.
In 1970s, pioneers and navigators flew over Jupiter for the first time, providing people with the first close-up image of Jupiter. The Galileo Jupiter probe launched by 1989 detected a dark ocean under Europa's ice, which may have given birth to primitive life.
In the early 1980s, when Voyager flew over Saturn, it not only found that Saturn's beautiful rings were a group of rings composed of thousands of rings, but also newly discovered 13 satellites, which increased the number of Saturn's satellites to 23, making it a big family of Enceladus.
Mars and the earth have many similarities. Many scientists believe that Mars may have had life, at least for a period of low-level life development, so the exploration of Mars is particularly eye-catching. Starting from 1975, Viking and Mars Pathfinder flew to Mars for field trips. As a result, no Martians were found on this barren and desolate red planet, and even no traces of life were found.
In addition to Pluto, humans also visited the other eight planets and their satellites in the solar system by space probes, and made many new discoveries. The solar probe Ulysses launched in 1990 also detected the solar wind at the north and south poles of the sun for the first time.
Since 1990s, Hubble Space Telescope, Compton Gamma Ray Telescope and Chandra X-ray Telescope have been sent into space orbit to detect distant celestial bodies and galaxies outside the solar system, observe black holes, neutron stars and quasars in the universe, and explore the secrets of the formation and evolution of the universe.
1998, the alpha magnetic spectrometer hosted by Ding Zhaozhong and developed by China was launched by the space shuttle to explore antimatter and try to reveal the mystery of BIGBANG.
Although the road to space exploration is arduous and long, with the continuous progress of space technology, mankind will eventually solve the mystery of the universe.
