Space probes have been placed into orbit around all the five planets known to the ancients: first Mars ( Mariner 9, 1971 ), then Venus ( Venera 9, 1975 ; but landings on Venus and atmospheric probes were performed even earlier ), Jupiter ( Galileo, 1995 ), Saturn ( Cassini / Huygens, 2004 ), and most recently Mercury ( MESSENGER, March 2011 ), and have returned data about these bodies and their natural satellites.

Aerobraking does not require a thick atmosphere – for example most Mars landers use the technique, and Mars ' atmosphere is only about 1 % as thick as Earth's.

The design retains most of the essential features of Mars Direct, but uses multiple medium-lift rocket launchers that are commercially available today ( such as the Ariane V or the Delta rocket ) to launch the crew vehicles, and their propulsion, separately, and mate them in orbit.

If there was life on Mars, after Mariner 4 most concluded it would probably be smaller, simpler forms.

All that is long in the past of the series ' 30th century plot, where Mars is an established human-settled planet, humans living mainly " in the fertile canal areas " while most of the planet is desert.

At present though, most of the water remaining on Mars is frozen.

If life exists at all on Mars, it is most likely to be located underground where liquid water can still exist.

In 1931, Nicholson and Mayall calculated its mass, based on its supposed effect on the gas giants, as roughly that of the Earth, while in 1949, measurements of Pluto's diameter led to the conclusion that it was midway in size between Mercury and Mars and that its mass was most probably about 0. 1 Earth mass.

It is also one of the possible ways that Mars has lost most of its atmosphere and that Mercury continually replenishes its tenuous surface-bounded exosphere.

Mars is considered by many to be the most likely candidate for terraforming.

On other planets and moons that experience more-active surface geological processes, such as Earth, Venus, Mars, Europa, Io and Titan, visible impact craters are less common because they become eroded, buried or transformed by tectonics over time.

His interest in space, however, was his primary focus, especially after reading science fiction stories by writers such as Edgar Rice Burroughs, which stirred his imagination about life on other planets, such as Mars.

( The same terms may be used analogously in describing other eclipses, e. g., the antumbra of Deimos crossing Mars, or Phobos entering Mars's penumbra )

Although the Greek-language-origin prefix geo refers to Earth, " geology " is often used in conjunction with the names of other planetary bodies when describing their composition and internal processes: examples are " the geology of Mars " and " Lunar geology ".

* In the Divine Comedy Joshua's spirit appears to Dante in the Heaven of Mars, where he is grouped with the other " warriors of the faith.

Detailed calculations for the orbit of the planet Mars first indicated to Kepler its elliptical shape, and he inferred that other heavenly bodies, including those farther away from the Sun, have elliptical orbits too.

The reference surfaces for some planets ( such as Earth and Mars ) are ellipsoids of revolution for which the equatorial radius is larger than the polar radius ; in other words, they are oblate spheroids.

The " Slumberland " of the title soon acquired a double meaning, referring not only to Morpheus's fairy kingdom, but to the state of sleep itself: Nemo would have dream-adventures in other imaginary lands, on the Moon and Mars, and in our own " real " world, made fantastic by the dream-state.

Grasping the bloody dagger, he swore by Mars and all the other gods that he would do everything in his power to overthrow the dominion of the Tarquinii and that he would neither be reconciled to the tyrants himself nor tolerate any who should be reconciled to them, but would look upon every man who thought otherwise as an enemy and till his death would pursue with unrelenting hatred both the tyranny and its abettors ; and if he should violate his oath, he prayed that he and his children might meet with the same end as Lucretia.

About 85 % of images and other data from NASA's twin Mars Exploration Rovers, Spirit and Opportunity, have reached Earth via communications relay by Odyssey.

While trying to find a suitable name, Mars remembered an incident which occurred when he was playing with a band called White Horse, when one of the other band members called the group " a motley looking crew.

Its aim is to show that Mars is an achievable goal through a practical series of technical and other projects, including these:

* actively supports NASA, ESA and other space agencies in their on-going exploration of Mars

* TMS-SD provides public outreach events to classrooms, libraries, museums and other organizations throughout the Southern California region with seven different multimedia programs: " Invasion from Earth-The Robotic Exploration of Mars "; " Mars Exploration Rovers-Year 4 "; " Mars on Earth-The Adventures of Space Pioneers in the Utah Desert "; " Mars on Earth-The Adventures of Space Pioneers in the Canadian Arctic: " Humans to Mars-How We'll Get There "; " A Close Look at Mars "; and " Mars in the Movies "

The main means of communication with members and the general public is the MSD Website with information on the ARCHIMEDES project, publications on Mars and other space subjects, the regular news, which can be commented by visitors of the website, the Space Forum and informative meetings.

The Italian Mars Society carries out scientific divulgation activities related to the Red Planet. It cooperates with the other European Mars Society chapters to build a knowledge network whose aim is to develop the interest of European people towards Mars exploration.

Mars Festival 2008 was smaller due to the efforts being made in other projects, particularly the Polish URC rover, named Skarabeusz.

Of the remaining planets, only Mars and Saturn have been observed as radio sources, and not very much information is available.

In Gnostic cosmology, the 7 letters spelling its name represent each of the 7 classic planets — Sun, Moon, Mercury, Venus, Mars, Jupiter, and Saturn.

The five major planets are associated with and even named after the elements: Jupiter 木星 is Wood ( 木 ), Mars 火星 is Fire ( 火 ), Saturn 土星 is Earth ( 土 ), Venus 金星 is Metal ( 金 ), and Mercury 水星 is Water ( 水 ).

Edmond Halley in 1692 put forth the idea of Earth consisting of a hollow shell about thick, two inner concentric shells and an innermost core, about the diameters of the planets Venus, Mars, and Mercury.

It has several benefits for NASA .” These scientists are researching how different amounts of light, temperature and carbon dioxide, along with plant species can be grown and cultivated on planets like Mars.

It is possible to put stations or spacecraft on orbits that cycle between different planets, for example a Mars cycler would synchronously cycle between Mars and Earth, with very little propellant usage to maintain the trajectory.

He found that each of the five Platonic solids could be uniquely inscribed and circumscribed by spherical orbs ; nesting these solids, each encased in a sphere, within one another would produce six layers, corresponding to the six known planets — Mercury, Venus, Earth, Mars, Jupiter, and Saturn.

Finding that an elliptical orbit fit the Mars data, he immediately concluded that all planets move in ellipses, with the sun at one focus — Kepler's first law of planetary motion.

The other group is almost certainly from Mars and are the only materials from other planets ever recovered by man.

Mars was one of the first planets visited, and the crew stayed on the surface for some time, finding water and experiencing a huge dust storm.

Spirits od the dead from various planets were taken to Mars and given new bodies to work.

The ionospheres of weakly magnetized planets such as Venus and Mars set up currents that partially deflect the solar wind flow, but do not have magnetospheres, per se.

Venus, Mercury and the outer planets Mars, Jupiter and Saturn were all identified by Babylonian astronomers.

To the Ancient Greeks, some " stars ", known as planets ( Greek πλανήτης ( planētēs ), meaning " wanderer "), represented various important deities, from which the names of the planets Mercury, Venus, Mars, Jupiter and Saturn were taken.

They are still not universal, however, as not all people use a solar-based calendar where the solstices occur every year in the same month ( as they do not in the Islamic calendar and Hebrew calendar, for example ), and the names are not useful for other planets ( Mars, for example ), even though these planets do have seasons.

Originally " drop-in " replacements were considered for higher performance, but a larger replacement for the S-IVB stage was later studied for missions to Mars and other high-load profiles, known as the S-N. Nuclear thermal space " tugs " were planned as part of the Space Transportation System to take payloads from a propellant depot in Low Earth Orbit to higher orbits, the Moon, and other planets.

He took his observations of dark and bright spots on the surfaces of Mars and Jupiter to be evidence of water and ice on those planets.
