Leipzig vs Mars

Informations

Leipzig (, also , , German: [ˈlaɪptsɪç] (listen); Upper Saxon: Leibz'sch) is the most populous city in the German state of Saxony. With a population of 600,000 inhabitants as of 2019 (1.1 million residents in the larger urban zone), it is Germany's eighth most populous city as well as the second most populous city in the area of former East Germany after (East) Berlin. Together with Halle (Saale), the largest city of the neighbouring state of Saxony-Anhalt, the city forms the polycentric conurbation of Leipzig-Halle. Between the two cities (in Schkeuditz) lies Leipzig/Halle Airport. Leipzig is located about 160 kilometres (99 mi) southwest of Berlin in the Leipzig Bay, which constitutes the southernmost part of the North German Plain, at the confluence of the White Elster River (progression: Saale→ Elbe→ North Sea) and two of its tributaries: the Pleiße and the Parthe. The name of the city as well as the names of many of its boroughs are of Slavic origin. Leipzig has been a trade city since at least the time of the Holy Roman Empire. The city sits at the intersection of the Via Regia and the Via Imperii, two important medieval trade routes. Leipzig was once one of the major European centres of learning and culture in fields such as music and publishing. After the Second World War and during the period of the German Democratic Republic (East Germany) Leipzig remained a major urban centre in East Germany, but its cultural and economic importance declined. Events in Leipzig in 1989 played a significant role in precipitating the fall of communism in Central and Eastern Europe, mainly through demonstrations starting from St. Nicholas Church. The immediate effects of the reunification of Germany included the collapse of the local economy, which had come to depend on highly polluting heavy industry, severe unemployment, and urban blight.

Starting around 2000, however, the decline was first arrested and then reversed and, since then, Leipzig has seen significant changes with the restoration of major historical buildings, the demolition of derelict properties of little historical value, and the development of new industries and a modern transport infrastructure.Leipzig today is an economic centre, is rated as the most livable city in Germany by the GfK marketing research institution, and has the second-best future prospects of all cities in Germany according to HWWI and Berenberg Bank. The city is one of two seats of the German National Library, as well as the seat of the German Federal Administrative Court. Leipzig Zoo is one of the most modern zoos in Europe and ranks first in Germany and second in Europe. Since the opening of the Leipzig City Tunnel in 2013, Leipzig forms the centrepiece of the S-Bahn Mitteldeutschland public transit system. Leipzig is currently listed as a "Sufficiency" level global city by the Globalization and World Cities Research Network, Germany's "Boomtown" and was the 2019 European City of the Year.Leipzig has long been a major centre for music, both classical as well as modern "dark alternative music" or darkwave genres. The Oper Leipzig is one of the most prominent opera houses in Germany. Leipzig is also home to the University of Music and Theatre "Felix Mendelssohn Bartholdy". The Leipzig Gewandhaus Orchestra, established in 1743, is one of the oldest symphony orchestras in the world. Johann Sebastian Bach is one among many major composers who lived and worked in Leipzig and, during a stay in the city, Friedrich Schiller wrote his poem "Ode to Joy".

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.
