1300172 D ear friends and families Hope this email finds you well. I have been living on Mars for a while and it was a very unforgettable experience for me. Life here is very interesting. I tried the rover on Mars and the airplane. We have greenhouses to conduct experimental research and VR equipment to learn new knowledge. Everything was very new to me, an experience I had never experienced before. With the help of my friends, I learned very useful knowledge. Temperatures on Mars range from approximately -125 to 23 degrees Fahrenheit. Mars has two small moons named Phobos and Deimos. Phobos and Deimos are not as round as our moon. They are much smaller and irregularly shaped. Both moons are heavily cratered, made of rock and iron. Phobos and Deimos are likely two asteroids captured by Mars' gravity. Since Mars has a smaller mass than Earth, the gravity on Mars' surface is less than the gravity on Earth's surface. Mars' surface gravity is only about 38 percent of Earth's surface gravity, so if you weighed 100 pounds on Earth, you would only weigh 38 pounds on Mars. The gravity of Mars is a natural phenomenon. Due to the law of universal gravitation, all objects with mass around Mars will be attracted to Mars. Because the Earth has less mass, its gravity is weaker than Earth's. The average gravitational acceleration on Mars is about 38% of the gravitational acceleration on Earth. Under the influence of such different gravity, I discovered many interesting phenomena. I could jump very high, as if I was flying. Although Mars is smaller than Earth, with only 11 percent of Earth's mass, and is 50 percent farther from the Sun, its climate has important similarities, such as the presence of polar ice caps, seasonal changes, and observable weather patterns. It attracts continued study by planetologists and climatologists. While Mars' climate has similarities to Earth's, including periodic ice ages, there are also important differences, such as much lower thermal inertia. The

scale height of the Martian atmosphere is about 11 kilometers, which is 60% higher than the Earth's atmosphere. Climate is closely related to the question of whether life exists or ever existed on Earth. I also learned many other things, such as the wavelengths and frequencies of various radiations, the position of the moon, and how the magnitude of light appears on the spectrum through different gases. All knowledge is very useful and deserves in-depth study. I am always learning new knowledge, and everything here is very novel. Words cannot express it as well as personal experience. I hope that if there is an opportunity in the future, I hope that you can also come to Mars, come here to have a look, and live for a while. I will prepare everything for you to ensure your quality of life. Best wishes 1300172
