Ankara vs Mars

Informations

Ankara ( ANK-ə-rə, also US: AHNK-ə-rə, Turkish: [ˈaŋkaɾa] (listen)), historically known as Ancyra ( an-SY-rə) and Angora ( ang-GOR-ə, also US: ANG-gə-rə), is the capital of Turkey. Located in the central part of Anatolia, the city has a population of 4.5 million in its urban center and over 5.6 million in Ankara Province, making it Turkey's second-largest city after Istanbul. Serving as the capital of the early Celtic country of Galatia (280--64 BC), and later of the Roman province with the identical name (25 BC--7th century), the city is very old with various Hattian, Hittite, Lydian, Phrygian, Galatian, Greek, Persian, Roman, Byzantine, and Ottoman archaeological sites. The Ottomans made the city the capital first of the Anatolia Eyalet (1393--late 15th century), and the Angora Vilayet (1867--1922). The historic center of Ankara is a rocky mountain climbing 150 m (500 ft) over the left bank of the Ankara River, a tributary of the Sakarya River. The hill remains crowned by the ruins of Ankara Castle. Although few of its outworks have survived, there are well-preserved examples of Roman and Ottoman architecture across the city, the most remarkable being the 20 BC Temple of Augustus and Rome that boasts the Monumentum Ancyranum, the inscription recording the Res Gestae Divi Augusti.

On 23 April 1920, the Grand National Assembly of Turkey was established in Ankara, which became the headquarters of the Turkish National Movement during the Turkish War of Independence. Ankara became the new Turkish capital upon the organization of the Republic on 29 October 1923, succeeding in this role the former Turkish capital Istanbul (Constantinople) following the collapse of the Ottoman Empire. The government is a prominent employer, but Ankara is also an important commercial and industrial city, located at the centre of Turkey's road and railway networks. The city gave its name to the Angora wool shorn from Angora rabbits, the long-haired Angora goat (the origin of mohair), and the Angora cat. The area is also famous for its pears, honey and muscat grapes. Although located in one of the driest regions of Turkey and surrounded largely by steppe vegetation (except for the forested areas on the southern periphery), Ankara can be considered a green city in terms of green areas per inhabitant, at 72 square metres (775 square feet) per head.

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.
