Guadalajara vs Mars

Informations

Guadalajara ( GWAH-də-lə-HAR-ə, Spanish: [ɡwaðalaˈxaɾa] (listen)) is a metropolis in western Mexico and the capital of the state of Jalisco. The city has a population of 1,460,148, while the Guadalajara metropolitan area has a population of 5,002,466, making it the second-largest metropolitan area in the country. Guadalajara has the second highest population density in Mexico, with over 10,361 people per square kilometre. Guadalajara is an international center of business, finance, arts, and culture, as well as the economic center of the Bajío region, one of the most productive and developed regions in Latin America.Guadalajara is the tenth largest metropolitan area in Latin America and a major Latin American tech hub and financial center. It is one of the most productive and globally competitive cities in the world. The city is an important center for science, technology, finance, culture, innovation, education, business, and tourism in Mexico. It is home to numerous landmarks, including Guadalajara Cathedral, the Teatro Degollado, the Templo Expiatorio, the Hospicio Cabañas, and the San Juan de Dios Market—the largest indoor market in Latin America.Guadalajara was founded on 14 February 1542 by Cristóbal de Oñate, a Basque conquistador, as the capital of the Kingdom of Nueva Galicia, part of the Viceroyalty of New Spain. After 1572, the Royal Audiencia of Guadalajara, previously subordinate to Mexico City, became the only authority in New Spain with autonomy over Nueva Galicia, owing to rapidly growing wealth in the kingdom following the discovery of silver. By the 18th century, Guadalajara had taken its place as Mexico's second largest city, following mass colonial migrations in the 1720s and 1760s.

During the Mexican War of Independence, independence leader Miguel Hidalgo y Costilla established Mexico's first revolutionary government in Guadalajara in 1810. The city flourished during the Porfiriato, with the advent of the industrial revolution, but its growth was hampered significantly during the Mexican Revolution. In 1929, the Cristero War ended within the confines of the city, when President Plutarco Elías Calles proclaimed the Grito de Guadalajara. The city saw continuous growth throughout the rest of the 20th century, attaining a 1 million metro population in the 1960s and passing 3 million in the 1990s. Guadalajara is a global city and one of Mexico's most important cultural centers. It is home to numerous mainstays of Mexican culture, including Mariachi, Tequila, and Birria and hosts numerous notable events, including the Guadalajara International Film Festival, the most important film festival in Latin America, and the Guadalajara International Book Fair, the largest book fair in the Americas. The city was the American Capital of Culture in 2005 and has hosted numerous global events, including the 1970 FIFA World Cup, the 1986 FIFA World Cup, the 1st Ibero-American Summit in 1991, and the 2011 Pan American Games. The city is home to numerous universities and research institutions, including the University of Guadalajara and the Universidad Autónoma de Guadalajara, two of the highest-ranked universities in Mexico and Latin America.

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.
