Mars vs Lázaro Cárdenas

Informations

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.

Lázaro Cárdenas del Río (Local Spanish pronunciation: [ˈlasaɾo ˈkaɾðenas] (listen); May 21, 1895 – October 19, 1970) was a general in the Constitutionalist Army during the Mexican Revolution and a statesman who served as President of Mexico between 1934 and 1940. He is best known for nationalization of the oil industry in 1938 and the creation of Pemex, the government oil company. He also revived agrarian reform in Mexico, expropriating large landed estates and distributing land to small holders in collective holdings (ejidos). Although he was not from the state of Sonora, whose generals had dominated Mexican politics in the 1920s, Cárdenas was loyal to Sonoran general and former president Plutarco Elías Calles (1924–28). Calles had founded the National Revolutionary Party (PNR) in the wake of the assassination of Sonoran general Alvaro Obregón, who served as president (1920–24) and was president-elect in 1928. Cárdenas was Calles's hand-picked candidate in 1934 to run for the presidency. While Calles did not hold the title of president, he had remained the power behind the presidency, and expected to maintain that role when Cárdenas took office. However, Cárdenas out-maneuvered him politically and eventually forced the former president into exile, establishing Cárdenas's legitimacy and power in his own right during his remaining time in office.

In 1938, Cárdenas transformed the structure of the party Calles founded, creating the Partido de la Revolución Mexicana (PRM), based on sectoral representation of peasants via peasant leagues, unionized workers, professionals, and the Mexican army. Cárdenas's incorporation of the army into the party structure was a deliberate move to diminish the power of the military and prevent their traditional intervention in politics through coups d'état. An important political achievement of Cárdenas was his complete surrender of power in December 1940 to his elected successor, Manuel Ávila Camacho, who was a political moderate without a distinguished military record. Cárdenas has been revered as "the greatest constructive radical of the Mexican Revolution," for reviving its ideals, but he has also been criticized as an "authoritarian populist." According to numerous opinion polls and analysts, Cárdenas is the most popular Mexican president of the 20th century.
