History of Mars ExplorationMars exploration had a long history. On October 10, 1960, the former Soviet Union launched a probe to Mars, which was the beginning of early exploration. In October 1964, the US Mariner 4 probe returned to Earth the first close-up image of the surface of Mars in human history. In 1971, the Soviet Union successfully launched Mars 3, becoming the first Mars lander. In 1972, the United States 'Mariner 9 landed on Mars and became the first artificial satellite on Mars.
Since the 1990s, the United States 'Braveheart, Opportunity, Curiosity, and other probes had successfully found evidence of the existence of Martian water. China's Tianwen-1 probe was successfully launched on July 23,2020. The first Mars exploration mission realized Mars orbit, landing and patrol exploration. At about 8:20 on May 15,2021, it successfully landed on the Utopia Plain in the northern hemisphere of Mars. China became the second country to achieve Mars Six.
So far, seven countries (international organizations) had carried out 47 Mars exploration missions, achieving the exploration of Mars. According to the development of Mars exploration, it could be roughly divided into three stages. The first stage was the early fly-by exploration, mainly for Mars fly-by exploration, transmitting Mars images, and detecting atmospheric parameters. The second stage was to understand the surface of Mars, mainly for orbit and landing exploration, including transmitting images, detecting the atmosphere, magnetic field, surface temperature, and other tasks. The third stage was to search for signs of life on Mars. The exploration methods were mainly landing and patrol exploration. The goal was to find evidence of the existence of Martian water and signs of life.

Is history fact or fiction? An explorationHistory is fact. Think about historical battles like the Battle of Waterloo. There are military records, eyewitness accounts, and physical evidence on the battlefield. These all prove that it was a real event that took place at a specific time. Of course, over time, stories might get embellished, but if we dig deep into the primary sources, we can separate the truth from the made - up parts. So, it's not fiction but a record of what actually happened in the past.

The History of Human Exploration and Flight* * Title: Human Exploration of Flight **
Flying had always been a dream filled with fantasy and desire in the hearts of humans. From ancient legends to modern high-tech aircraft, mankind's exploration of flight had gone through a long and winding process.
In ancient times, the dream of flying had already been reflected in myths and legends. In ancient Egyptian mythology, the goddess Isis had wings to soar in the sky. In ancient Greek legend, Daedalus and his son Icarus used feathers and wax to make wings and tried to fly over the Aegean Sea. These legends reflected the early human yearning and initial imagination for flight.
In ancient China, kites were considered the first form of man-made aircraft. Legend has it that they were invented by Mozi and improved by Lu Ban. Wooden kites were used as communication and detective tools in wars. There was also the Sky Lantern (Kongming Lantern), which was said to have been invented by Zhuge Liang. Its principle was the same as that of a hot air balloon, and it had many military uses in ancient times. In ancient times, there were also some "flying men" who tried to fly by themselves. Although most of their attempts ended in failure, this brave spirit of exploration took the first step for flight exploration.
As time passed, the ornithopter appeared after the 17th century. Da Vinci was particularly famous for his research in this area. His manuscripts and sketches provided the theoretical basis for the development of aircraft. The ornithopter was an important stage in the transition from ancient flying people to modern aircraft.
The year 1783 was an important year in the history of flight. The Mongolfi brothers carried out the world's first manned flight in a hot air balloon. The balloon flew in the air for 25 minutes. This event opened a new era for humans to use buoyancy to fly. Two months later, their competitors also conducted further flight tests, such as flying longer distances and longer times in hydrogen balloons.
At the beginning of the 19th century, Sir George Kelly published "On Air Navigation", which determined the four forces of flight (gravity, lift, drag, and thrust), proposed the concept of fixed-wing aircraft, and designed a manned glider, introducing the world into the study of aerospace. In 1852, Henry Gifal piloted an airship to complete the first flight with controllable power, proving the possibility of powered air travel. In 1876, the internal combustion engine designed by Nicholas Otto laid the foundation for the new era of aviation.
In 1903, the Wright brothers took off from Kitty Hawk, North Caroline, and made the first controlled, continuous flight. Although each flight was short, this feat opened the era of human freedom in the sky. Less than six years later, Feng Ru completed the test flight of the aircraft he designed and manufactured in China, Feng Ru No. 1. Soon after the aircraft appeared, it was used in war. During World War I and World War II, it was unprecedentedly developed. From the initial simple reconnaissance aircraft to fighter aircraft and heavy bomber equipped with weapons, the structure and performance of the aircraft were constantly improved.
Since the 20th century, aviation technology continued to develop rapidly, and helicopters began to gradually develop and improve. In terms of space exploration, the Voyager 1 probe had been flying for 47 years. Although it would take about 30,000 years to completely fly out of the solar system, it also represented the efforts of humans to explore space on a larger scale.
From ancient fantasies and initial attempts, to modern scientific theory research and continuous innovation of aircraft, and then to the great achievements of modern aerospace, the journey of human exploration and flight reflected the great spirit of human beings to constantly pursue dreams, bravely explore innovation, and break through themselves. This process also showed that with the continuous advancement of science and technology, human exploration of flight would continue to develop. In the future, there might be more unimaginable flight technologies and achievements.
