Mars is the fourth planet from the sun and second smallest planet in the solar system. Mars is know as the "Red Planet" and was named after a Roman of war, Mars.
The fastest spacecraft launched from Earth was NASA's New Horizons mission, which is en route to Pluto. In January 2006, the probe left Earth at 36,000 mph (58,000 kph). The time it would take such a probe to get to Mars would be: Closest approach: 942 hours (39 days)
A lot of planets are bigger than Earth. For example, 318 Earths could fit inside of Jupiter. Mars is not quite so big. In fact, Mars is one of only two planets in the solar system to be significantly smaller than Earth.
The solar day, by contrast, is the time it takes for the Earth to rotate on its axis so that the Sun appears in the same position in the sky. This position changes slightly each day, but on Earth, a mean solar day works out to being 24 hours long. On Mars, a solar day lasts 24 hours, 39 minutes, and 35 seconds.
But one big difference is that the gravity on Mars' surface is much lower than it is here on Earth – 62% lower to be precise. At just 0.38 of the Earth standard, a person who weighs 100 kg on Earth would weigh only 38 kg on Mars.

Mars Facts. Mars is the fourth planet from the Sun and is the second smallest planet in the solar system. Named after the Roman god of war, Mars is also often described as the “Red Planet” due to its reddish appearance. Mars is a terrestrial planet with a thin atmosphere composed primarily of carbon dioxide. After the Earth, Mars is the most habitable planet in our solar system due to several reasons: Its soil contains water to extract. It isn't too cold or too hot. There is enough sunlight to use solar panels. However, the surface is not hospitable to humans or most known life forms due to greatly reduced air pressure, and an atmosphere with only 0.1% oxygen. ... Human survival on Mars would require complex life-support measures and living in artificial environments.

Mars Planet Profile

Mars is home to the tallest mountain in the solar system.
Olympus Mons, a shield volcano, is 21km high and 600km in diameter. Despite having formed over billions of years, evidence from volcanic lava flows is so recent many scientists believe it could still be active.
- There are signs of liquid water on Mars.
  For years Mars has been known to have water in the form of ice. The first signs of trickling water are dark stripes or stains on crater wall and cliffs seen in satellite images. Due to Mars’ atmosphere this water would have to be salty to prevent it from freezing or vaporising. The journey from Earth to Mars takes about 300 days. Every two years Mars is at its closest point, only 55 million km from Earth, and it's the ideal time to send a spacecraft. Travel time depends on the positions of the planets and how much fuel you're willing to burn

Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System after Mercury. In English, Mars carries a name of the Roman god of war, and is often referred to as the "Red Planet" because the reddish iron oxide prevalent on its surface gives it a reddish appearance that is distinctive among the astronomical bodies visible to the naked eye. Mars is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth. The rotational period and seasonal cycles of Mars are likewise similar to those of Earth, as is the tilt that produces the seasons. Mars is the site of Olympus Mons, the largest volcano and second-highest known mountain in the Solar System, and of Valles Marineris, one of the largest canyons in the Solar System.
Mars can easily be seen from Earth with the naked eye, as can its reddish coloring. Its apparent magnitude reaches −2.91,^[8] which is surpassed only by Jupiter, Venus, the Moon, and the Sun. Optical ground-based telescopes are typically limited to resolving features about 300 kilometers (190 mi) across when Earth and Mars are closest because of Earth's atmosphere.

Several groups as NASA, Elon Musk and Mars-One are planning to bring the first people ever to Mars around the year 2030. A Return to the moon is anticipated within five year and at least ESA and China are working on plans for a moon station. If people will go it will be for longer periods or even for a permanent stay. These human Martians or Lunarists will have to eat. Especially for longer stays food will have to be grown at the spot to feed the inhabitants.

Three experiments were carried out (in 2013, 2015 and 2016) to investigate if it is possible to grow food on Mars and moon soil simulants provided by NASA. In 2015 we could harvest the first tomatoes, radishes and rye. In 2016 we were able to harvest ten different crops, including the above mentioned crops, but also beans, peas, carrots and potatoes. Because there are heavy metals present in the soils we had to test the vegetables, but luckily they turned out to be save to eat. This paved the way to the first ever ‘Martian diner’ based on the grown crops for our crowdfunders.

Now it is time to set the next step. Just growing crops is simply not enough. All non-eaten parts of the crops have to be returned to the soil and broken down so the nutrients will be released again for the next generation of crops. What we actually need is a small sustainable ecosystem that also is able to deal with the inhabitants poop and pee. A crucial part of the ecological chain is the earthworm. It will eat the organic matter, chew it to small parts and mix it with the soil. Bacteria can then break it down further. Worms also dig burrows and by doing so they aerate the soil and make it possible for water to enter the soil easily. All this is essential for an abundant crop harvest Length of day: 1d 0h 40m

Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System after Mercury. In English, Mars carries a name of the Roman god of war, and is often referred to as the "Red Planet" because the reddish iron oxide prevalent on its surface gives it a reddish appearance that is distinctive among the astronomical bodies visible to the naked eye. Mars is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth.

Our tale of two planets begins four billion years ago. One planet was Earth, and the other planet was Mars, and the two had much in common in their infancy. Rivers and lakes etched their surfaces, craters pockmarked their faces, and volcanoes rose from their plains. But something seems to have changed on one and not the other.

In Earth’s burbling warm water, fate and chemistry combined amino acids into complex molecules, and in a process we still don’t understand, these gave rise to single cells that figured out how to make copies of themselves. Tiny mistakes in those copies eventually turned them into oxygen-exhaling organisms we call algae. Endless forms flowed from these humble ancestors, and after eons, there we were: All of human culture and hope and possibility arising within a tiny slice of time.
Mars was not so lucky. Mars dried up. Mars is small, about half Earth’s diameter, so it cooled off faster than Earth did after their birth in the cloud of dust left over from the sun’s creation. Compared to its overall volume, more of Mars’ mass is exposed to the icy blackness of space. As it cooled, its iron-nickel core solidified. When this happened, we think, the Martian magnetic field shut down, robbing Mars of its protective shield, of the sort that still safeguards Earth from solar and cosmic rays. Time and the brightening sun stripped away the Martian atmosphere before the planet’s algae, if it existed, had a chance to make the air thick and warm. Mars turned to rust before any skeletons could adorn its deserts, before any creatures could look up and contemplate their place among the other dots in the night sky. While Earth is fecund and bursting with life, Mars is, and may have always been, barren.

To me, this is why Mars is the best planet. A few simple changes turn its history into our history, and vice versa. That’s the key thing; that could have been us.

Mars and Earth have approximately the same landmass.
Even though Mars has only 15% of the Earth’s volume and just over 10% of the Earth’s mass, around two thirds of the Earth’s surface is covered in water. Martian surface gravity is only 37% of the Earth’s (meaning you could leap nearly three times higher on Mars).
Mars is home to the tallest mountain in the solar system.
Olympus Mons, a shield volcano, is 21km high and 600km in diameter. Despite having formed over billions of years, evidence from volcanic lava flows is so recent many scientists believe it could still be active.
Only 18 missions to Mars have been successful.
As of September 2014 there have been 40 missions to Mars, including orbiters, landers and rovers but not counting flybys. The most recent arrivals include the Mars Curiosity mission in 2012, the MAVEN mission, which arrived on September 22, 2014, followed by the Indian Space Research Organization’s MOM Mangalyaan orbiter, which arrived on September 24, 2014. The next missions to arrive will be the European Space Agency’s ExoMars mission, comprising an orbiter, lander, and a rover, followed by NASA’s InSight robotic lander mission, slated for launch in March 2016 and a planned arrival in September, 2016.
Mars has the largest dust storms in the solar system.
They can last for months and cover the entire planet. The seasons are extreme because its elliptical (oval-shaped) orbital path around the Sun is more elongated than most other planets in the solar system.
On Mars the Sun appears about half the size as it does on Earth.
At the closest point to the Sun, the Martian southern hemisphere leans towards the Sun, causing a short, intensely hot summer, while the northern hemisphere endures a brief, cold winter: at its farthest point from the Sun, the Martian northern hemisphere leans towards the Sun, causing a long, mild summer, while the southern hemisphere endures a lengthy, cold winter.
Pieces of Mars have fallen to Earth.
Scientists have found tiny traces of Martian atmosphere within meteorites violently ejected from Mars, then orbiting the solar system amongst galactic debris for millions of years, before crash landing on Earth. This allowed scientists to begin studying Mars prior to launching space missions.
Mars takes its name from the Roman god of war.
The ancient Greeks called the planet Ares, after their god of war; the Romans then did likewise, associating the planet’s blood-red colour with Mars, their own god of war. Interestingly, other ancient cultures also focused on colour – to China’s astronomers it was ‘the fire star’, whilst Egyptian priests called on ‘Her Desher’, or ‘the red one’. The red colour Mars is known for is due to the rock and dust covering its surface being rich in iron.
There are signs of liquid water on Mars.
For years Mars has been known to have water in the form of ice. The first signs of trickling water are dark stripes or stains on crater wall and cliffs seen in satellite images. Due to Mars’ atmosphere this water would have to be salty to prevent it from freezing or vaporising.
One day Mars will have a ring.
In the next 20-40 million years Mars’ largest moon Phobos will be torn apart by gravitational forces leading to the creation of a ring that could last up to 100 million years.

The bright rust color Mars is known for is due to iron-rich minerals in its regolith — the loose dust and rock covering its surface.According to NASA, the iron minerals oxidize, or rust, causing the soil to look red.
The red planet is home to both the highest mountain and the deepest, longest valley in the solar system. Olympus Mons is roughly 17 miles (27 kilometers) high, about three times as tall as Mount Everest, while the Valles Marineris system of valleys.
Mars has the largest volcanoes in the solar system, including Olympus Mons, which is about 370 miles (600 km) in diameter, wide enough to cover the entire state of New Mexico.
Mars is much colder than Earth, in large part due to its greater distance from the sun. The average temperature is about minus 80 degrees Fahrenheit (minus 60 degrees Celsius)
NASA is working hard now to discover whether there is life on Mars. The United States and other countries have been sending spacecraft to orbit or land there since the 1960s, and each mission teaches us more about this fascinating planet. We have learned that even though Mars is more similar to Earth than anywhere else in the solar system, and therefore is a good place to look for life, it is still different from Earth in many ways.
In 1976, NASA landed robotic spacecraft named Viking 1 and Viking 2 on Mars. One of these landers worked there for nearly 4 years and the other lasted more than 6 years. Think of spending that much of your life studying another world! Among their scientific experiments were the only ones so far specifically designed to discover whether there was something tiny (like bacteria) living in the soil.
Even if there were no life on Mars, it would be exciting to know whether there used to be life there. So in addition to looking for living bacteria, NASA will be searching for tiny fossils that might indicate life got a start early in Mars' history but, unlike on our home planet, it did not survive and evolve into larger life forms.
Many of the studies of Mars will involve robots, like the ones that have gone there before, but getting more advanced with each flight. Someday a spacecraft may pick up samples from Mars and bring them back to Earth where they can be studied in our best laboratories. Eventually, humans may make the daring journey, but many important problems have to be solved before trying such an expensive, difficult, and exciting voyage.
