Versailles vs Mars

Informations

The Palace of Versailles ( vair-SY, vur-SY; French: Château de Versailles [ʃɑto d(ə) vɛʁsɑj] (listen)) was the principal royal residence of France from 1682, under Louis XIV, until the start of the French Revolution in 1789, under Louis XVI. It is located in the department of Yvelines, in the region of Île-de-France, about 20 kilometres (12 miles) southwest of the centre of Paris.A simple hunting lodging and later a small château with a moat occupied the site until 1661, when the first work expanding the château into a palace was carried out for Louis XIV. In 1682, when the palace had become large enough, the king moved the entire royal court and the French government to Versailles. Some of the palace furniture at this time was constructed of solid silver, but in 1689 much of it was melted down to pay for the cost of war. Subsequent rulers mostly carried out interior remodeling, to meet the demands of changing taste, although Louis XV did install an opera house at the north end of the north wing for the wedding of the Dauphin and Marie Antoinette in 1770. The palace has also been a site of historical importance. The Peace of Paris (1783) was signed at Versailles, the Proclamation of the German Empire occurred in the vaunted Hall of Mirrors, and World War I was ended in the palace with the Treaty of Versailles, among many other events.

The palace is now a historical monument and UNESCO World Heritage site, notable especially for the ceremonial Hall of Mirrors, the jewel-like Royal Opera, and the royal apartments; for the more intimate royal residences, the Grand Trianon and Petit Trianon located within the park; the small rustic Hameau (Hamlet) created for Marie Antoinette; and the vast Gardens of Versailles with fountains, canals, and geometric flower beds and groves, laid out by André le Nôtre. The Palace was stripped of all its furnishings after the French Revolution, but many pieces have been returned and many of the palace rooms have been restored. In 2017 the Palace of Versailles received 7,700,000 visitors, making it the second-most visited monument in the Île-de-France region, just behind the Louvre and ahead of the Eiffel Tower.After 82 days of closure due to the COVID-19 outbreak in 2020, the Palace of Versailles has re-opened to the public again.

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.
