Planet Mars

In some cultures or historical periods, marrying within the family was seen as a way to maintain social status, wealth, or power within the family. It was also sometimes practiced to keep property and resources within the family. However, marrying relatives can also increase the risk of genetic disorders in offspring due to a lack of genetic diversity.

Mars has a thin atmosphere, mainly of Carbon Dioxide (95.32%). Nitrogen makes up 2.7%, Argon 1.6%, Oxygen 0.13% and Carbon Monoxide makes up around 0.08%.

When considering distance from the sun, the planet that come after Mercury is Venus.

To date, no human being has gone to Mars, but NASA is planning to send a manned mission to Mars in a few decades.

Even though there has been no manned mission on Mars, a great deal of unmanned missions have been sent to the red planet, including a lot of rovers. Mars rovers are large tank-like vehicles that work with solar energy and are programmed with signals from the earth.

Mars' atmosphere is almost entirely carbon dioxide gas (95%) with only a little nitrogen (3%)(as well as 1.5% argon)

Compare with Earth: 77% nitrogen, 20% oxygen, 1% argon, 1% water vapour, 1% other gases.

Except for the dwarf planet Ceres (largest of the asteroids), there is no real planet between Mars and Jupiter, Instead, there is a wide, sparsely populated belt of asteroids. This is referred to as the "Main Belt".

It was once speculated that a planet did exist between the orbits of Mars and Jupiter, based on the distances of the known planets from the Sun. Many of the early astronomers viewed the asteroid belt as the remains of a planet that was destroyed by a devastating impact with another stellar object.

However, the current theory is that no planet ever formed there due to gravitational interactions between the Sun and Jupiter. These could have stopped the accretion process from actually allowing the planetesimals to "gel" together. The mass of the belt is relatively low, suggesting that much of the original mass there has been dispersed.

A Mars rover is a robotic vehicle designed to explore the surface of Mars. These rovers are equipped with cameras, sensors, and various scientific instruments to study the Martian environment, geology, and climate. They are controlled remotely from Earth by a team of scientists and engineers.

The gravity of Uranus is about 0.86 that of Earth. This means an object that weighs 100 pounds on Earth would weigh 86 pounds on Uranus.

Mars is the windiest planet in the solar system. Dust devils are known to be created when the winds get very windy.

There is no ring around the Mars now but Phobos (Moon of the Mars) Might form a ring around the Mars about 15billion(mabey million) years later.

There are two rovers currently active on the planet Mars. Spirit which which is exploring the Gusev Crater and Opportunity which is exploring the Meridiani Planum. Both rovers have far outlasted their intended lifespan of 90 sols (Martian days) due to wind sweeping dust off of their solar panels.

The atmosphere of Mars is predominantly composed of carbon dioxide (95.3%), with traces of nitrogen (2.7%), argon (1.6%), and oxygen (0.13%). There are also small amounts of water vapor, methane, and other gases in the Martian atmosphere.

Mars period of revolution around the sun, its orbit, is 686.971 Earth days long. The time it takes to make one spin on its axis relative to the background stars is 24h:37min:22.663sec.

The apparent day or solar day on mars is 24h : 39min : 35sec.

To go to Mars, you would need a spacecraft that can carry both crew and supplies for the journey that can withstand the challenges of space travel, advanced life support systems to sustain humans for the duration of the trip, and a deep understanding of how to navigate the complexities of interplanetary travel including trajectories, communication delays, and landing techniques.

Depending on the positions of the planets, Mars could sometime be the brightest in the sky. The planet which becomes the brightest overall is Venus - when its in the right place it will be brighter than the brightest star, even visible before sunset/sunrise if you know where to look.

The two VIKING probes arrived in Mars orbit in 1976 when they started sending photographs back to Earth. The two orbiters continued sending photographs and the landers conducted experiments on the planet's surface until they failed as follows:Viking 2 Orbiter: July 1978

Viking 2 Lander: April 1980

Viking 1 Orbiter: August 1980

Viking 1 Lander: November 1982.

Uranus is the third largest planet by diameter, but the fourth largest by mass (after Neptune).

Phobos orbits Mars in a close-in, nearly circular orbit that is closer to Mars than any other moon is to its planet in the solar system. It moves in a westward (retrograde) motion compared to the rotation of Mars, rising in the west and setting in the east.

No human has been on Mars yet. The only missions to Mars have been robotic, with various rovers like Curiosity and Perseverance sent by NASA to explore the planet's surface. Crewed missions to Mars are being planned for the future.

There is no way to get a spacecraft from Earth orbit to Mars, or to establish an orbit around mars, without some form of propulsion being used.

However, the Russian scientist Konstantin Tsiolkovsky proposed, back in 1924, that the pressure of sunlight on an object in space could be used to propel a spacecraft. (See link.) In 1960, science fiction great Arthur C. Clarke wrote a story in Boy's Life magazine about a race from Earth orbit to the Moon using solar sailboats.

So it might be possible to fly a spacecraft from Earth to Mars using a solar sailer, but it would probably not be possible to get into orbit without using rocket engines once you get there.

You really can't, however, the best way to start would be to find a way to keep oxygen in the atmosphere, so that you could grow plants and then introduce primary, secondary and tertiary consumers.

It is approximately 228 million km, or 142 million miles.

This number is average. Mars travels in an elliptical orbit around the Sun. Sometimes it gets closer and other times it's more distant. At its closest point, Mars is only 207 million km from the Sun. Astronomers call this point in a planet's orbit perihelion. And then at its most distant point, called aphelion.

We know about most of the common elements on Mars, such as iron, silicon, hydrogen and oxygen. Scientists expect to find almost every metal in the periodic table on Mars, but the exploring probes sent there have not been equipped to do that much analysis. The probes were intended to discover if there was any water, and if there was life.

So far we know that there IS water on Mars, but no proof of life has been found yet.

Mars is the only rocky planet to have two moons, named Phobos and Deimos. Earth only has one moon and both Mercury and Venus have none.
