Information on Mars
Mars was one of the eight planets in the solar system. It was the fourth closest to the sun and the second smallest planet in the solar system after Mercury. It was a terrestrial planet. In China, it was known as the "Mars". In ancient Roman mythology, it was imagined as Mars, the god of war, or Ares, the god of war in Greek mythology. Mars was 55 million kilometers away from Earth and 400 million kilometers away from Earth. Its average diameter was 6794 kilometers, its surface area was about 145 million square kilometers, its volume was about 163 billion cubic kilometers, its mass was 6.42× 1023 kg, and its average density was 3.93 g/cm. The atmosphere was thin, mainly composed of carbon dioxide (95%), nitrogen (2.7%), and Argon (1.6%). There were also traces of carbon dioxide, water vapor, and oxygen. The oxygen content was extremely low. The temperature ranges from 27 ° C (300 ° K) to-138 ° C (145 ° K), and the global average annual surface temperature is-63 ° C (210 ° K). The magnetic field is weaker than Earth's, with a surface gravity of 3.693 m/s2 and a maximum brightness of-2.9. There were two natural satellites, Phobos and Deimos. At the end of the 16th century, the Danish-born Astronomist Tyco began to systematically observe Mars. In 1960, the Soviet Union began to launch a Mars probe. After many failures, the landing module of the Mars 3 probe was launched on February 8, 1971, and landed on Mars in December of the same year. The United States also conducted Mars exploration. On July 20 and August 7, 1976, the landing modules of the "Viking 1" and "Viking 2" probes landed successfully on Mars. On November 7, 1996, the United States launched the Mars Global Explorer (MGS). In mid-March 1998, it began to map Mars and obtain a large amount of data. On June 2, 2003, the European Space Agency launched Mars Express. In November 2013, India's Mangarian Mars Orbiter was successfully launched. The United United Arab Emirates Republic's Hope Mars probe was launched in July 2020 and entered scientific orbit in March 2021 for a two-year data collection. On May 15,2021, China's "Tianwen-1" Six Patrol Vehicle successfully landed in the pre-selected six zones, and the first Mars exploration mission was successful. Mars 'orbit had an eccentric ratio of 0.09 and was oval in shape. Its orbit radius was 1.52 astronomical units, and its rendezvous period with Earth was about 779.87 days (about once every two years and two months). When the Earth and Mars moved to the same side of the Sun, it was called "Mars Opposition." Every 15 - 17 years, the distance was particularly close, which was called a big opposition. It was the best time to observe Mars. Mars had terrain similar to Earth's, such as deserts, hills, canyons, and dry riverbeds, indicating that Mars once had water. In terms of its internal structure, the iron core in the center of the core may be in a semi-melted state; the mantle is composed of Silicate Rock, which may have been in a liquid state at the beginning of its formation, but now there is no sign of flowing. The giant rift on the surface of Mars is caused by the movement of the mantle; The crust is mainly composed of volcanic rocks. The outer layer of rock is about 80 kilometers thick in the southern hemisphere and about 35 kilometers in the northern hemisphere. 95.3% of the Martian atmosphere was carbon dioxide, with the rest being nitrogen, nitrogen, carbon dioxide, oxygen, oxygen, and hydrogen. Water vapor accounted for about 0.01%. Water on Mars exists in the form of steam or ice in the air, on the ground, and underground. In addition, there was also a China Hong Kong actor named Mars (Jiang Rongfa). He was born in Shanghai on February 28, 1954. He entered the entertainment industry in 1962 and joined the Cheng Long family in 1979 to begin his martial arts career. His representative works included films such as "The Golden Cauldron Wandering Dragon Soul-Seizing Order" and "The Lady Boss". In 2003, he won the 39th Taiwan Film Golden Horse Awards-Best Action Design (nominated). The novel "Mars of Paradise" is equally exciting. Everyone is welcome to read it!
Information on Mars
Mars was one of the eight planets in the solar system. It was the fourth planet closest to the sun and the second smallest planet in the solar system after Mercury. It was one of the four terrestrial planets in the solar system. In China, it was called "Mars". In Western ancient Roman mythology, it was imagined as the God of War, Mars, or Ares in Greek mythology. Mars was only 55 million kilometers away from the Earth, and it was 400 million kilometers away from the Earth. Its average diameter was 6794 kilometers, its surface area was about 145 million square kilometers, its volume was about 163 billion cubic kilometers, its mass was 6.42× 1023 kg, and its average density was 3.93 g/cubic centimeter. The atmosphere was very thin. It was mainly composed of carbon dioxide (95%), nitrogen (2.7%), and argon (1.6%). There were also traces of carbon dioxide, water vapor, and oxygen. The oxygen content was extremely low. The temperature on Mars varied from 27 ° C (300 ° K) to-138 ° C (145 ° K), and the global average annual surface temperature was-63 ° C (210 ° K). Mars 'magnetic field was weaker than Earth's, with a surface gravity of 3.693 m/s2 and a maximum brightness of-2.9. It had two natural satellites: Deimos and Deimos. In 1960, the Soviet Union began to launch probes to Mars. During the process, many attempts failed. On February 8, 1971, the Soviet Union's Mars 3 probe was launched, and its lander landed softly on Mars in December of the same year. The United States also conducted Mars exploration. On July 20 and August 7, 1976, the landing modules of the "Viking 1" and "Viking 2" probes landed successfully on Mars. On November 7, 1996, the United States launched the Mars Global Explorer (MGS). In mid-March 1998, it began to map Mars and obtain a large amount of terrain and climate data. On June 2, 2003, the European Space Agency launched the Mars Express to detect whether there was water on Mars. In November 2013, India's Mangarian Mars Orbiter was successfully launched. The United United Arab Emirates Republic's Hope Mars probe was launched in July 2020 and entered scientific orbit in March 2021 to begin a two-year data collection. On May 15,2021, China's "Tianwen-1" Six Patrol Vehicle successfully landed in the pre-selected six zones, and the first Mars exploration mission was successful. The Martian calendar began in 1955 on Earth. On November 12th, 2024, Mars began its 38th New Year. Mars revolved around the sun and rotated at an angle. The rotation period was 24 hours, 37 minutes, and 22.7 seconds, and the inclination of the axis was 25.19 degrees. It was very close to Earth, so Mars had the cycle of day and night and the four seasons. Mars was cold in winter and hot in summer, but the overall temperature was much lower than Earth's. The annual average temperature was about-60 degrees Celsius. Moreover, due to its orbit around the sun's eccentricity of 0.093, which was much flatter than Earth's orbit, the length of Mars 'four seasons was very uneven. Spring and summer in the northern hemisphere were about one-third longer than autumn and winter. When the sun's direct point on Mars moved from the southern hemisphere to the northern hemisphere to the equator, it was the vernal equinox in the northern hemisphere of Mars. On this day, the Martian world basically had an equal day and night. From the vernal equinox, the northern hemisphere of Mars entered spring, and the southern hemisphere entered autumn. The global sandstorm season on Mars also ended. Mars's oval orbit caused it to be close to the sun at times. When the southern hemisphere of Mars was in spring and summer, Mars was relatively closer to the sun. The temperature difference between the northern and southern hemisphere was greater. In the second half of the year, there would usually be violent sandstorms, sometimes even throughout the entire planet, lasting for more than three months. In addition, Mars was a fictional planet that appeared in the comics. There were Green Martians, White Martians, Yellow Martians, Kriglo Martians, Solazis, and other species living on Mars. Among them, the Green Martians were extinct. In the sci-fi concept, the "Cold Light" aircraft with a universal vertical take-off and landing platform would be deployed in low-gravity environments such as Mars in the future. Its power source mainly relied on a force field, which could be flexibly maneuvered at low speeds. The novel "Mars of Paradise" is equally exciting. Everyone is welcome to read it!

In addition, Martian meteorites were formed when asteroids or comets hit Mars, causing the surface of Mars to be ejected into space. After floating in space, they might enter Earth's orbit, burn in the Earth's atmosphere, and fall to Earth. About 200 Martian meteorites found on Earth may have come from five specific impact craters in the two volcanic regions of Tharsis and Elysium on Mars.

In terms of observation, Mars was observed on November 6, 2024. It rose before sunrise from the beginning of 2024. At sunrise, it was at a low altitude in the southeast. As time passed, the rise time became earlier, the altitude increased, and the brightness increased from 0.6 magnitude in September to-0.3 magnitude in November. From December 8th, Mars in the sky of Cancer changed from anterograde to retrograde and entered the best observation period. On January 16th, 2025, Mars was in Gemini, and the altitude was very high. At midnight, it was close to the upper sky and was least affected by the atmosphere. During this period, Mars 'brightness would gradually increase from-0.3 magnitude to-1.4 magnitude.

Mars was one of the eight planets in the solar system. It was the fourth closest to the sun and the second smallest planet after Mercury. It was a terrestrial planet. Mars had different names in different cultures. In China, it was called the "Mars". In Western ancient Roman mythology, it was imagined to be the God of War, Mars (equivalent to Ares in Greek mythology). It was 55 million kilometers away from Earth at its closest point and 400 million kilometers away at its farthest point. Mars had an average diameter of 6794 kilometers, a surface area of about 145 million square kilometers, a volume of about 163 billion cubic kilometers, a mass of 6.42× 1023 kg, and an average density of 3.93 grams per cubic centimeter. The atmosphere of Mars was very thin. It was mainly composed of carbon dioxide (95%), nitrogen (2.7%), and argon (1.6%). There were also traces of carbon dioxide, water vapor, and oxygen. The oxygen content was extremely low. Its temperature ranges from 27 ° C (300 ° K) to-138 ° C (145 ° K), and the global average annual surface temperature is-63 ° C (210 ° K). Mars 'magnetic field was weaker than Earth's, with a surface gravity of 3.693 m/s2 and a maximum brightness of-2.9. It also had two natural satellites, Deimos and Deimos. Since the end of the 16th century, when the Danish-born Astronomist Tyco began to make systematic observations, human exploration of Mars continued to develop. Many countries and regions had launched Mars probes, such as the Soviet Union, the United States, the European Space Agency, the United Arab United Arab Emirates, and China. These exploration activities had obtained a large amount of information on Mars 'topography, climate, and so on. The surface of Mars was filled with canyons, craters, mountain ranges, and huge volcanoes formed by volcanic activity. A year on Mars was about 1.88 years on Earth, and a day was about 24 hours and 37 minutes. Most of its water existed below the surface in the form of ice, but there were also traces of ancient rivers and lakes, which indicated that there might have been liquid water on Mars in the past and potential habitat for life. In the comic, there were still many Martian groups such as green, white, and yellow. Among them, the green Martians were extinct. The novel "Mars of Paradise" is equally exciting.
