What is the name of my country's Mars probe? The difference between the sun and Mars

In the solar system, Mars, like other planets, needs to rotate and revolve around the sun. Mars is one of them. Mars is a planet that moves around the sun regularly under the sun's gravity. What is the difference between the sun and Mars? Today we will learn about it, including the name of my country's Mars probe.

The name of my country's Mars probe

Tianwen-1 is China's first Mars probe. In late April 2020, China's Mars exploration mission was officially named the Tianwen series, and the first exploration mission was named Tianwen-1. The Mars exploration project is another major space exploration project for China after the manned space program and the lunar exploration program.

The name Tianwen-1 comes from "Heavenly Questions", a long poem by Qu Yuan, a famous Chinese patriotic poet. This poem describes the changes of yin and yang in heaven and earth, natural phenomena such as the sun, moon and stars, and expresses the author's courageous spirit of exploration in pursuit of truth.

The exploration mission for Mars mainly includes exploring information on life activities on Mars, including whether there has been life on Mars in the past and present, the conditions and environment for the survival of life on Mars, and the detection of the origin of life and extraterrestrial life.

Scientific research on Mars itself will include detection of the Martian magnetosphere, ionosphere and atmosphere, as well as environmental science, including the topography, geomorphic features and zoning of Mars, the composition and distribution of Martian surface materials, and geological characteristics.

Difference Between Sun and Mars

There are many essential differences between the Sun and Mars. The Sun is a star, while Mars is a planet. In the solar system, Mars, like other planets, needs to revolve around the Sun. The Sun is located in the middle of the solar system, while Mars is one of the eight planets, revolving around the Sun.

The sun is a star that is large enough in mass and volume to ignite the hydrogen in its interior, thereby using nuclear energy to make itself glow. Mars is a terrestrial planet with thin air on the surface, mainly sand and stone, and very little liquid water.

Since the volume and mass of the sun are much larger than other planets in the solar system, the sun's gravity causes the planets around the sun to rotate and revolve regularly. Mars is one of them. Mars is a planet that revolves around the sun under the sun's gravity and moves regularly.

Since the sun is the only star in the solar system, it is usually surrounded by other planets. There are eight planets in the solar system, among which Mars is located between the earth and Jupiter. It is the fourth planet from the inside to the outside of the solar system, and there are four other planets orbiting the sun at the same time.

Radiation from Mars to Earth

Mars is mainly composed of iron, and also contains compounds such as sulfur and magnesium, which will definitely have radiation to the Earth. Astronauts going to Mars to explore must wear special aviation suits to avoid radiation. However, since the Earth has an atmosphere that can weaken radiation, and the radiation from Mars is very small compared to the sun, there is no need to worry.

There is a certain amount of radiation on Mars. Generally, astronauts who go to explore Mars will wear special aviation suits. The aviation suits have the functions of keeping warm and providing oxygen. They can help astronauts overcome the low temperature and thin air on Mars. The most important thing is to prevent the body from being exposed to radiation from Mars.

Scientists speculate that many years ago, Mars may have had conditions such as an atmosphere and water that allowed species to survive, just like Earth. However, for some unknown reason, the magnetic field inside Mars disappeared, and the atmosphere was taken away by the gravity of the sun, and the liquid water evaporated directly, turning into the Mars we see today.

Mars definitely has some radiation. The core of Mars is mainly iron, and contains sulfur, magnesium and other elements, but this radiation is far less powerful than the radiation from the sun. Although Mars is very close to the Earth, the Earth still has an atmosphere that can weaken the radiation, so the radiation from Mars is minimal.
