Tianwen No. 1's Journey to Mars
Tianwen-1 was launched on July 23,2020 at the Wenchang Space Launch Site in Hainan, starting its journey to Mars. It was composed of an orbiter and a landing patrol, carrying a total of 13 scientific detection equipment. During the seven-month journey to Mars, there were many challenges. After all, the success rate of human Mars exploration was only about 50%, the distance was far, and the signal transmission delay was serious. On February 10,2021, Tianwen-1 entered the orbit of Mars and became China's first man-made Mars satellite. On February 24, it entered the orbit of Mars to carry out orbit exploration. On May 15, the six patrol devices successfully landed in the pre-selected six zones in the southern part of the Utopia Plains on Mars. This process was called "shocking nine minutes". Due to the communication delay, it could not be controlled in real time. It needed to rely on its own computer to complete the process from entering the Martian atmosphere to landing, including the stages of airflow deceleration, umbrella deceleration, dynamic deceleration, hovering obstacle avoidance, buffer landing, etc. On May 22, the patrol left the six platforms and began to patrol and explore. For the first time, Tianwen-1 achieved the three goals of Mars orbit, landing and patrol in one mission. The novel "Mars of Paradise" is equally exciting. Everyone is welcome to read it!
Tianwen No.1's Journey to Mars
Tianwen-1 was the probe that carried out China's first Mars exploration mission. It was composed of an orbiter and a six patrol. ** I. Launch and Flight History ** 1. ** Lift-off ** - On July 23,2020, Tianwen-1 was launched by the Long March 5 Yao-4 launch vehicle at the Wenchang Space Launch Site in Hainan, starting its journey to Mars. 2. ** To Mars ** - After about seven months of flight, it arrived near Mars in February 2021 and was captured by Mars. Among them, on February 10,2021, it entered the orbit of Mars, becoming China's first man-made Mars satellite; on February 24th, it entered Mars parking orbit and carried out a three-month orbit exploration, which laid the foundation for six Mars. ** 2. Landing process ** 1. ** Prepare for Landing ** - The entire landing process was very complicated and thrilling. Due to the long distance between Earth and Mars, the communication time was delayed by about 18 minutes, and the landing process was only about 9 minutes, which could not be controlled in real time. Tianwen-1 had to rely on its own computer to complete the entire landing process independently. - The landing process went through six stages. The first was the landing preparation segment. The orbiter adjusted its attitude and trajectory and separated from the landing inspection assembly's outer cover. 2. ** Deceleration process ** - Then, they entered the deceleration section. The outer cover entered the atmosphere at a speed of 4.8 km/s and a suitable angle, using atmospheric friction to decelerate to 460 m/s. - At an altitude of about 11 kilometers, they entered the parachute deceleration segment and opened the parachute to further decelerate to about 95 meters per second. In this stage, they would also complete the operation of throwing away the bottom heat shield, opening the landing legs of the landing platform, throwing away the back cover and parachute. - Then there was the power deceleration section, which used the recoil generated by the ignition of the 7500N engine at the bottom of the landing platform to further reduce the speed to about 1.5m/s. 3. ** Landing Operation ** - Hovering and obstacle avoiding segment. At a height of 100 meters from the surface of Mars, the speed would be reduced to zero, and the target would hover in a state of stillness relative to the surface. The target would adjust its horizontal position to avoid obstacles. - Finally, there was the buffer landing segment. Relying on the cushion of the landing legs, the landing platform successfully landed on the pre-selected landing zone in the southern part of the Utopia Plains on Mars on May 15, 2021, marking that China had become the third country in the world after the Soviet Union and the United States to successfully land a probe on Mars. ** 3. Patrol Detection ** 1. ** Zhurong begins work ** - On May 22,2021, the rover (Zhurong) left the landing platform and arrived at the surface of Mars. It began to patrol and explore. Zhurong's name originated from the God of Fire in ancient China mythology. It implied that the application of fire promoted the development of human civilization and also symbolized that human exploration of Mars was like chasing light. 2. ** Quest Details ** - Tianwen-1 carried a total of 13 scientific exploration equipment for Mars global topography and geological structure detection, material composition detection, shallow structure and water distribution detection, space environment detection and Mars physical field detection. It also took a panoramic image of Mars and transmitted images and sounds back to Earth from 55 million kilometers away. For the first time in the world's aerospace history, Tianwen-1 successfully achieved the three goals of Mars orbit, landing and patrol in one mission. This marked that China had entered the world's advanced ranks in the field of planetary exploration and was an important milestone in China's aerospace history.

Tianwen-1 probes gravitational waves inside Mars
Tianwen-1 obtained high-resolution temperature data through radio occultation experiments. These data were used by the research team of the Astronomy Department of Beijing Normal University to study the gravitational waves inside Mars. They combined the observations of the Mars Global Explorer (MGS) to conduct an in-depth analysis of parameters such as the vertical wave-length, frequency, and energy density in the Martian atmosphere, revealing new characteristics of the gravitational waves inside Mars. For example, the vertical wave-length was usually between 6 and 13 kilometers, and the horizontal wave-length could be extended to thousands of kilometers. It was almost vertical and exhibited low-frequency inertia gravity wave characteristics. Tianwen-1's data also showed that these waves had a higher fluctuation intensity in the Martian atmosphere, a higher energy density, and less energy dissipation during transmission.

A Journey to Mars
The journey to Mars was full of unknowns and challenges, but it also contained infinite possibilities and hope. It was an extremely long journey from Earth to Mars. If they took a rocket to Mars, they would need to travel at a speed of more than 75000 miles per hour. It would take at least four months to reach Mars. After arriving near Mars, they had to change to the Mars lander, which was traveling at about 15000 miles per hour. The journey would be very bumpy. After successfully setting foot on Mars, what greeted his eyes was an endless yellow sky. Due to the difference in gravity between Mars and Earth, people would hop forward. There would be many scientists, engineers, and pilots living together in the residential area of Mars. Finding life on Mars and exploring water sources were important missions, and robots would become indispensable helpers in this. Mars had many amazing sights, such as Mount Olympus, which was the tallest volcano in the solar system, three times taller than Mount Everest, and Mariner Canyon, which was deep and wide, ten times longer and five times deeper than the Grand Canyon. However, the journey to Mars also faced many difficulties. The latest research shows that the human body may not be able to withstand the challenges of a trip to Mars. Long-term space life will change the structure and function of the kidneys, and the radiation in the universe will cause permanent damage to the kidneys. However, with the advancement of science and technology, China plans to launch Tianwen 3 to land on Mars in 2030 and collect samples to return to Earth. We look forward to more mysteries of Mars being unveiled. The novel "Mars of Paradise" is equally exciting. Everyone is welcome to read it!

Finally, Mars appeared in our field of vision. Its unique red appearance seemed to be telling us about its mysterious past. The spaceship slowly landed on the surface of Mars. The moment it landed, a slight vibration was felt. The moment I stepped out of the ship, a strange feeling welled up in my heart. The gravity on Mars is much lower than on Earth. I feel like a feather. The terrain here was very strange. It was filled with huge craters and towering mountains. Red sand and dust fluttered gently in the weak wind. We began our exploration of Mars. The first was to find a water source, because water was a key element for the existence of life. After some exploration, we found a substance that looked like ice at the bottom of a crater. This discovery made everyone very excited. If the ice could be turned into liquid water, then there would be greater hope for the transformation of Mars. Next, we tested the composition of the Martian soil and found that it contained some elements that were beneficial to plant growth. This means that in the future, we might be able to grow plants on Mars and improve the atmosphere. During our exploration, we also encountered a storm unique to Mars. The wind howled and swept over, sending sand and dust flying all over the sky. We quickly hid in the temporary shelter and waited for the storm to pass. Even though we are facing danger, everyone is full of fighting spirit because we know that this is a challenge that must be experienced when exploring Mars. As time passed, our journey to Mars was coming to an end. On the way back to the spaceship, I couldn't help but look back. My heart was filled with nostalgia for this red planet.

Journey to Mars
Journey to Mars In the distant future, Mars, the mysterious red planet, became a popular destination for human exploration. I was fortunate enough to be a member of the Mars Exploration Team, and I started a journey to Mars that was full of unknowns and surprises. When the spaceship slowly left the embrace of the Earth, I saw the Earth gradually becoming smaller through the porthole. The blue planet was so beautiful and fragile. As the journey progressed, the scenery outside the window was gradually replaced by the vast universe. The stars were like bright gems embedded in the black sky. After a long flight, Mars finally appeared in front of them. Its unique red surface was filled with a primitive and rough beauty. The spacecraft landed steadily on the surface of Mars. The moment it landed, a strong sense of excitement welled up in his heart. Stepping out of the spaceship, the first thing he felt was the gravity on Mars, which was completely different from Earth's. Every step he took felt like he was jumping. The atmosphere of Mars was very thin, and the sky was a faint pink. In the distance were rolling sand dunes. These sand dunes were like ocean waves frozen by time. The red sand grains rustled under their feet. We began to explore the mysteries of Mars. In a seemingly ordinary pile of rocks, he found some strange crystal structures. These crystals flickered with a mysterious light, as if they were telling the ancient history of Mars. After instrument testing, they found that they contained rare minerals on Earth, which might be an important clue to unravel the geological evolution of Mars. During our exploration, we also found traces of water that we suspected existed in the past. The dry riverbed meandered across the Martian land, indicating that Mars might have had a relatively humid environment a long time ago, and perhaps it had once nurtured life. This discovery has given us a new understanding of Mars. As the sun gradually set in the west, night arrived on Mars. The temperature dropped sharply, and we hid in the temporary living quarters. Through the observation window in the cabin wall, I saw that the night sky of Mars was filled with twinkling stars. They were brighter and clearer than those seen on Earth. This trip to Mars was not only an exploration of an unknown planet, but also a test of human courage and curiosity. It made me deeply feel the infinite mysteries of the universe, and also made me have a deeper love and cherish for Earth, the home of mankind. In the future, I believe that Mars will establish a closer relationship with Earth and become an important outpost for human exploration of the universe.
