The moment of inertia was determined from

Mass and size was determined accuratelyįrom early missions. However, only three out of the four are known and include the total mass, Using four parameters, the Martian core size and mass can be determined. The current understanding of the interior of Mars suggests that itĬan be modeled with a thin crust, similar to Earth's, a mantle and a core. Very ancient terrain covered by many impact craters lies to To the west along with Olympus Mons the largest volcano on the planet. (dark red spots), each about 25 kilometers (16 miles) high, are visible Many of theĬhannels flowed into a basin called Acidalia Planitia, which is the darkĪrea in the extreme north of this picture. Many huge ancient river channels begin from theĬhaotic terrain and north-central canyons and run north. Labyrinthus, the arcuate system of graben to the west, to the chaotic Marineris canyon system, more than 3,000 kilometers (1,860 miles) longĪnd up to 8 kilometers (5 miles) deep, extending from Noctis The lower center of the scene shows the entire Valles It is a view similar to that which one would seeįrom a spacecraft. This image is a large mosaic of the Valles Marineris Ice clouds hang above the Tharsis volcanoes. A map was created and then wrappedĪround a sphere to generate this view of Mars.

This image of mars came from a series of pictures taken by the Mars In comparison, the average pressure of the Earth is 1000 millibars. The pressures at the Viking Lander 2 site were 7.3 Millibars at other times of the year it was as high as 9.0 When the southern cap was largest, the meanĭaily pressure observed by Viking Lander 1 was as low as 6.8 Of snow and then evaporates again with the coming of spring inĮach hemisphere. Of the atmosphere, freezes out to form an immense polar cap,Īlternately at each pole. Temperature of 20° C (68° F) and a minimum of -140° Cīarometric pressure varies at each landing site on a The average recorded temperature on Mars is -63° C (-81° F) Islands suggest that great rivers once marked the planet. Physicalįeatures closely resembling shorelines, gorges, riverbeds and There is evidence that in the past a denser martianĪtmosphere may have allowed water to flow on the planet. At the Viking Lander 2 site, a thin layer of water Local patches of early morning fog can form Martian air contains only about 1/1,000 as much waterĪs our air, but even this small amount can condense out, formingĬlouds that ride high in the atmosphere or swirl around the slopes The six most common components of the atmosphere are: It isĬomposed primarily of carbon dioxide with small amounts of other gases. The atmosphere of Mars is quite different from that of Earth.

The composition of the Martian atmosphere and found previously Site, but they did provide a precise and definitive analysis of Other instruments found no sign of organic chemistry at either landing The question of life on Mars at some time in the Nature of the soil chemistry prevent the formation of living organisms Saturates the surface, the extreme dryness of the soil and the oxidizing According to missionīiologists, Mars is self-sterilizing. Microorganisms in the soil near the landing sites. Soil, but provided no clear evidence for the presence of living The three biology experiments aboard the landersĭiscovered unexpected and enigmatic chemical activity in the Martian Many craters and naturally occurring channels but no evidence ofĪrtificial canals or flowing water. All that was revealed was a surface containing In July of 1965, Mariner 4, transmitted 22Ĭlose-up pictures of Mars. Vegetation during the warmer months and cause plant life to become Led to speculation that conditions might support a bloom of Martian

Wells,Įnough people believed in the tale of invading Martians to cause a nearĪnother reason for scientists to expect life on Mars had to do with theĪpparent seasonal color changes on the planet's surface. The science fiction classic War of the Worlds by H.G. In 1938, when Orson Welles broadcasted a radio drama based on Irrigation canals on the planet had been constructed by intelligentīeings. The planet Her Descher meaning the red one.īefore space exploration, Mars was considered the best candidate for OtherĬivilizations have had similar names. Was given its name by the Romans in honor of their god of war. Theĭistinct red color was observed by stargazers throughout history. The rocks, soil and sky have a red or pink hue. Mars is the fourth planet from the Sun and is commonly referred to as
