Kunming vs Mars

Informations

Kunming is the capital and largest city of Yunnan province, People's Republic of China. Also known as Yunnan-Fu, today it is a prefecture-level city and the political, economic, communications and cultural centre of the province as well as the seat of the provincial government. The headquarters of many of Yunnan's large businesses are in Kunming. It was important during World War II as a Chinese military center, American air base, and transport terminus for the Burma Road. Located in the middle of the Yunnan–Guizhou Plateau, Kunming is located at an altitude of 1,900 metres (6,234 feet) above sea level and at a latitude just north of the Tropic of Cancer. As of 2014, Kunming has a population of 6,626,000 with an urban population of 4,575,000, and is located at the northern edge of Dian Lake, surrounded by temples and lake-and-limestone hill landscapes. Kunming consists of an old, previously walled city, a modern commercial district, residential zones and university areas. Kunming is also one of the top 200 science cities in the world by scientific research as tracked by the Nature Index. The city has an astronomical observatory, and its institutions of higher learning include Yunnan University, Kunming University of Science and Technology, Yunnan University of Finance and Economics, Kunming Medical University, Yunnan Normal University, Yunnan Agricultural University and Southwest Forestry University.

On the northeast mountainous outskirt is a bronze temple dating from the Ming dynasty, the largest of its kind in China. Its economic importance derives from its geographical position. It is positioned near the border with Southeastern Asian countries, serving as a transportation hub in Southwest China, linking by rail to Vietnam and by road to Burma, Laos and Thailand. This positioning also makes it an important trade center in this region of the nation. It also houses some manufacturing, chiefly the processing of copper, as well as various chemicals, machinery, textiles, paper and cement. Though having a nearly 2,400-year history, its modern prosperity dates only from 1910, when the railway from Hanoi was built. The city has continued to develop rapidly under China's modernization efforts. Kunming's streets have widened while office buildings and housing projects develop at a fast pace. Kunming has been designated a special tourism center and as such sports a proliferation of high-rises and luxury hotels.

Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, being larger than only Mercury. In English, Mars carries the name of the Roman god of war and is often referred to as the "Red Planet". The latter refers to the effect of the iron oxide prevalent on Mars's surface, which gives it a reddish appearance distinctive among the astronomical bodies visible to the naked eye. Mars is a terrestrial planet with a thin atmosphere, with surface features reminiscent of the impact craters of the Moon and the valleys, deserts and polar ice caps of Earth. The days and seasons are comparable to those of Earth, because the rotational period as well as the tilt of the rotational axis relative to the ecliptic plane are similar. Mars is the site of Olympus Mons, the largest volcano and highest known mountain on any planet in the Solar System, and of Valles Marineris, one of the largest canyons in the Solar System. The smooth Borealis basin in the northern hemisphere covers 40% of the planet and may be a giant impact feature. Mars has two moons, Phobos and Deimos, which are small and irregularly shaped. These may be captured asteroids, similar to 5261 Eureka, a Mars trojan.Mars has been explored by several uncrewed spacecraft. Mariner 4 was the first spacecraft to visit Mars; launched by NASA on 28 November 1964, it made its closest approach to the planet on 15 July 1965. Mariner 4 detected the weak Martian radiation belt, measured at about 0.1% that of Earth, and captured the first images of another planet from deep space. The Soviet Mars 3 mission included a lander, which achieved a soft landing in December 1971; however, contact was lost seconds after touchdown. On 20 July 1976, Viking 1 performed the first successful landing on the Martian surface. On 4 July 1997, the Mars Pathfinder spacecraft landed on Mars and on 5 July released its rover, Sojourner, the first robotic rover to operate on Mars.

The Mars Express orbiter, the first European Space Agency (ESA) spacecraft to visit Mars, arrived in orbit on 25 December 2003. In January 2004, the Mars Exploration Rovers, named Spirit and Opportunity, both landed on Mars. Spirit operated until 22 March 2010 and Opportunity lasted until 10 June 2018. On 24 September 2014, the Indian Space Research Organisation (ISRO) became the fourth space agency to visit Mars when its maiden interplanetary mission, the Mars Orbiter Mission spacecraft, arrived in orbit.There are investigations assessing the past habitability of Mars, as well as the possibility of extant life. Astrobiology missions are planned, including the Perseverance and Rosalind Franklin rovers. Liquid water on the surface of Mars cannot exist due to low atmospheric pressure, which is less than 1% of the atmospheric pressure on Earth, except at the lowest elevations for short periods. The two polar ice caps appear to be made largely of water. The volume of water ice in the south polar ice cap, if melted, would be sufficient to cover the planetary surface to a depth of 11 metres (36 ft). In November 2016, NASA reported finding a large amount of underground ice in the Utopia Planitia region. The volume of water detected has been estimated to be equivalent to the volume of water in Lake Superior.Mars can easily be seen from Earth with the naked eye, as can its reddish coloring. Its apparent magnitude reaches −2.94, which is surpassed only by Venus, the Moon and the Sun. Optical ground-based telescopes are typically limited to resolving features about 300 kilometres (190 mi) across when Earth and Mars are closest because of Earth's atmosphere.
