Recife vs Mars

Informations

Recife (Brazilian Portuguese: [ʁeˈsifi] (listen)) is the fifth-largest urban area in Brazil with 4,054,866 inhabitants, the second largest urban area of the North/Northeast Regions, and the capital and largest city of the state of Pernambuco in the northeast corner of South America. The population of the city proper was 1,625,583 in 2016. The first slave port in the Americas, Recife was founded in 1537, during the early Portuguese colonization of Brazil, as the main harbor of the Captaincy of Pernambuco, known for its large scale production of sugar cane. It was the former capital Mauritsstad of the 17th century colony of New Holland of Dutch Brazil, established by the Dutch West India Company. The city is located at the confluence of the Beberibe and Capibaribe rivers before they flow into the South Atlantic Ocean. It is a major port on the Atlantic. Its name is an allusion to the stone reefs that are present by the city's shores. The many rivers, small islands and over 50 bridges found in Recife city centre characterise its geography and led to the city being called the "Brazilian Venice". As of 2010, it is the capital city with the highest HDI in Northeast Brazil and second highest HDI in the entire North and Northeast Brazil (second only to Palmas).The Metropolitan Region of Recife is the main industrial zone of the State of Pernambuco; major products are those derived from cane (sugar and ethanol), motor vehicles, ships, oil platforms, electronics, software, and others. With fiscal incentives by the government, many industrial companies were started in the 1970s and 1980s. Recife has a tradition of being the most important commercial hub of the North/Northeastern region of Brazil, with more than 52,500 business enterprises in Recife plus 32,500 in the Metro Area, totaling more than 85,000.

A combination of a large supply of labor and significant private investments turned Recife into Brazil's second largest medical hub (the first being São Paulo); modern hospitals with state-of-the-art equipment receive patients from several neighbouring States.Recife stands out as a major tourist attraction of the Northeast, both for its beaches and for its historic sites, dating back to both the Portuguese and the Dutch colonization of the region. The beach of Porto de Galinhas, 60 kilometers (37 mi) south of the city, has been repeatedly awarded the title of best beach in Brazil and has drawn many tourists. The Historic Centre of Olinda, 7 kilometers (4.3 mi) north of the city, was declared a UNESCO World Heritage site in 1982, and both cities' Brazilian Carnival are among the world's most famous. The city is an education hub, and home to the Federal University of Pernambuco, the largest university in Pernambuco. Several Brazilian historical figures, such as the poet and abolitionist Castro Alves, moved to Recife for their studies. Recife and Natal are the only Brazilian cities with direct flights to the islands of Fernando de Noronha, a World Heritage Site.The city was one of the host cities of the 2014 FIFA World Cup. Additionally, Recife hosted the 2013 FIFA Confederations Cup and the 1950 FIFA World Cup. The city, despite having a higher crime rate than the southern region of Brazil, is considered the safest state capital in northeastern region. It has a much lower crime rate than other regional capitals, such as Salvador or São Luís. Despite that, crime rose 440% in 2015.

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.
