Mars vs Brisbane City

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.

Brisbane ( (listen) BRIZ-bən) is the capital of and the most populated city in the Australian state of Queensland, and the third most populous city in Australia. Brisbane's metropolitan area has a population of over 2.5 million, and the South East Queensland metropolitan region, centred on Brisbane, encompasses a population of more than 3.6 million. The Brisbane central business district stands on the historic European settlement and is situated inside a peninsula of the Brisbane River, about 15 kilometres (9 miles) from its mouth at Moreton Bay, a bay of the Coral Sea. The metropolitan area extends in all directions along the hilly floodplain of the Brisbane River Valley between Moreton Bay and the Taylor and D'Aguilar mountain ranges. It sprawls across several of Australia's most populous local government areas (LGAs)—most centrally the City of Brisbane, which is by far the most populous LGA in the nation. The demonym of Brisbane is "Brisbanite", whilst common nicknames include "Brissy", "River City" and "Brisvegas".One of the oldest cities in Australia, Brisbane was founded upon the ancient traditional lands of the Jagera people, including the Turrbal group, who named the area Meanjin. Named after the Brisbane River on which it is located—which in turn takes its name from Scotsman Sir Thomas Brisbane, the Governor of New South Wales at the time of the city's founding—the area was chosen as a place for secondary offenders from the Sydney Colony. The Moreton Bay penal settlement was founded in 1824 at Redcliffe, 28 kilometres (17 mi) north of the central business district, but was soon abandoned and moved to North Quay in 1825, opening to free settlement in 1842.

Brisbane was chosen as the capital when Queensland was proclaimed a separate colony from New South Wales in 1859. During World War II, Brisbane played a central role in the Allied campaign and served as the South West Pacific headquarters for United States Army General Douglas MacArthur.A diverse city with 32.2% of its metropolitan population being foreign born, Brisbane is classified as a global city (Beta +), and ranks highly in ratings of liveable cities. Brisbane is well known for its distinct Queenslander architecture which forms much of the city's built heritage. The city is noted for its cuisine brunches, outdoor dining, and rooftop bar scene. Brisbane was also the origin of the Anzac Day tradition through the works of Canon David John Garland. A transportation hub, Brisbane is served by a large suburban rail network, popular bus and ferry networks as well as Australia's third-busiest airport and seaport. Brisbane is a popular tourist destination. Major landmarks and attractions include South Bank Parklands, the Queensland Cultural Centre (home to the Queensland Museum, the Queensland Art Gallery, the Gallery of Modern Art and other institutions), the Story Bridge, Fortitude Valley, the Riverwalk network, the D'Aguilar National Park, Lone Pine Koala Sanctuary, Mount Coot-tha Reserve and Moreton Bay.
