Cedar Rapids vs Mars

Informations

Cedar Rapids () is the second-largest city in Iowa and is the county seat of Linn County. The city lies on both banks of the Cedar River, 20 miles (32 km) north of Iowa City and 100 miles (160 km) northeast of Des Moines, the state's capital and largest city. It is a part of the Iowa City/Cedar Rapids Region of Eastern Iowa which includes Linn, Benton, Cedar, Iowa, Jones, Johnson, and Washington counties.As of the 2010 United States Census, the city population was 126,326. The estimated population of the three-county Metropolitan Statistical Area, which includes the nearby cities of Marion and Hiawatha, was 255,452 in 2008. Cedar Rapids is an economic hub of the state, located at the core of the Interstate 380 corridor. The Cedar Rapids Metropolitan Statistical Area (MSA) is also a part of a Combined Statistical Area (CSA) with the Iowa City MSA. This CSA plus two additional counties are known as the Iowa City-Cedar Rapids (ICR) Corridor and collectively have a population of nearly 500,000.

A flourishing center for arts and culture in Eastern Iowa, the city is home to the Cedar Rapids Museum of Art, the National Czech & Slovak Museum & Library, the Paramount Theatre, Orchestra Iowa, Theatre Cedar Rapids, the African American Museum of Iowa, and the Iowa Cultural Corridor Alliance. In the 1990s and 2000s, several Cedar Rapidians became well-known actors, including Ashton Kutcher, Elijah Wood, Terry Farrell, and Ron Livingston. The city is the setting for the musical The Pajama Game and the comedy film Cedar Rapids. Cedar Rapids is nicknamed the "City of Five Seasons", for the so-called "fifth season," which is time to enjoy the other four. The symbol of the five seasons is the Tree of Five Seasons sculpture in downtown along the north river bank. The name "Five Seasons" and representations of the sculpture appear throughout the city in many forms.

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.
