About the Red Planet
The Red Planet is the fourth planet from the Sun and is also known as Mars. This planet is named after the Roman god of war. It is a desert world with a very thin atmosphere. The temperature on Mars can range from −140°C at the poles to 20°C at the equator.
The red planet is the fourth planet from the sun.
The red planet is the fourth planet from the sun. Mars is about half the size of Earth and has a diameter of 4,200 miles (6,800 kilometers). Mars is often called the “Red Planet” because its surface appears reddish in color.
Mars has two small moons, Phobos and Deimos. Phobos orbits closer to Mars than any other moon in the solar system. Deimos is so small that it is only about as big as a city block.
Mars has a thin atmosphere that is made mostly of carbon dioxide. The pressure of the atmosphere on Mars is only about 1% of the pressure on Earth, so it doesn’t protect Mars very well from incoming meteoroids. Meteoroids sometimes create impact craters on Mars when they hit the surface. The largest crater on Mars is called Olympus Mons, which is about 16 miles (25 kilometers) wide and 83 miles (134 kilometers) across.
It is also known as Mars.
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 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 caps of Earth.
The History of the Red Planet
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System. Named after the Roman god of war, it is often described as the “Red Planet” because the iron oxide prevalent on its surface gives it a reddish appearance. The first manned mission to Mars was launched by the Soviet Union on 3 November 1960.
The first recorded observation of Mars was by the Babylonians in the 7th century BC.
In Mesopotamia, the first recorded observation of Mars was by the Babylonians in the 7th century BC. They named it “Nergal” after their god of war. The ancient Greeks did not adopt this name; instead, they called it “Hermes”. The Romans later named it “Mars” after their god of war.
The first telescopic observations were made by Galileo Galilei in 1609. He noted certain surface features which were later given names by others in honor of him, such as the “Sea of Galilei”. In 1877, Italian astronomer Giovanni Schiaparelli used a telescope to map Mars and gave many features Latin names, most of which are still used today. Schiaparelli’s maps showed Fine System features, which were later found to be an optical illusion caused by watching Mars through Earth’s turbulent atmosphere.
Mars is now known to be a very dry and inactive world, with a thin carbon dioxide atmosphere. It has been extensively studied by spacecraft sent from Earth, beginning with Mariner 4 in 1965. These probes have revealed much about Mars, including evidence that water once flowed on its surface and that there may have been primitive life forms there in the past. However, the search for extraterrestrial life on Mars continues and is currently one of NASA’s top priorities.
The first detailed map of Mars was made by Giovanni Schiaparelli in 1877.
Giovanni Schiaparelli’s map of Mars, made in 1877, was the first detailed map of the Red Planet. Schiaparelli used a telescope to observe Mars for several years, and his map was incredibly accurate for its time. It showed features such as Martian “seas” and “continents”, as well as the planet’s two moons, Phobos and Deimos.
The Geography of the Red Planet
The red planet is desert-like with an atmosphere that is about 1% as dense as Earth’s. The temperature on the surface averages about minus 80 degrees Fahrenheit. Despite these conditions, there are some interesting features on the surface of Mars.
The red planet has a diameter of 4,217 miles (6,779 kilometers).
Mars is the fourth planet from the sun. It is also the second smallest planet in our solar system. Measuring just half the size of Earth, Mars is a cold, desert-like planet whose surface features are reminiscent of the moon. The red planet has a diameter of 4,217 miles (6,779 kilometers). Like Earth, Mars has seasons, polar ice caps, volcanoes, canyons and weather. However, its day is only 37 minutes longer than Earth’s. A year on Mars lasts 687 Earth days or one Martian year.
The atmosphere of Mars consists of 96% carbon dioxide, 1.9% argon and 2.7% nitrogen with traces of oxygen and water vapor. The air pressure on Mars is only about one-third as much as it is on Earth. This makes Mars a very difficult place for humans to visit without special equipment to help them breathe.
The surface temperature on Mars varies widely depending on the time of day and season, but it averages about minus 80 degrees Fahrenheit (minus 60 degrees Celsius). The temperature can range from minus 195 degrees Fahrenheit (minus 125 degrees Celsius) at the winter poles to a balmy 68 degrees Fahrenheit (20 degrees Celsius) near the equator during local noon in Martian springtime.
It has two moons, Phobos and Deimos.
The red planet is so-called because of its reddish appearance. It is also known as the “Red Planet” because of its high iron oxide content, which gives it a reddish hue.
Mars is the fourth planet from the Sun and is about half the size of Earth. It has two moons, Phobos and Deimos, which are thought to be captured asteroids. Mars has an atmosphere that is thin and mainly composed of carbon dioxide, nitrogen, and argon.
Dust storms on Mars can cover the entire planet and last for months. The planet has a temperature range from -140 degrees Fahrenheit at the poles to 80 degrees Fahrenheit at the equator. Although Mars appears to be dry now, there is evidence that liquid water once flowed on its surface.
The Climate of the Red Planet
The planet Mars is known as the Red Planet because of its reddish appearance. Mars has a thin atmosphere that does not allow for much weather. The planet does have some wind and dust storms. The storms can be large enough to cover the entire planet and can last for months.
The red planet has an average temperature of -81 degrees Fahrenheit (-63 degrees Celsius).
The red planet has an average temperature of -81 degrees Fahrenheit (-63 degrees Celsius). The minimum temperature ever recorded on Mars was -195 degrees Fahrenheit (-125 degrees Celsius) and the maximum temperature was 95 degrees Fahrenheit (35 degrees Celsius). The planet has an atmosphere that is much thinner than Earth’s atmosphere. The atmospheric pressure on the Martian surface is only about 1% of the pressure at Earth’s sea level.
It has a thin atmosphere that is mostly carbon dioxide.

Mars is about half the size of Earth. It has a thin atmosphere that is mostly carbon dioxide. The planet has cold winters and dusty summers. Mars has lots of iron, which makes it red.
Mars is a deserts planet. There are huge volcanoes, canyons, and mountains on Mars. The biggest volcano in the solar system, Olympus Mons, is on Mars. Valles Marineris is a huge canyon that would stretch from New York to Los Angeles on Earth.
The Exploration of the Red Planet
The first spacecraft to orbit Mars was Mariner 9 in 1971.
The first spacecraft to orbit Mars was Mariner 9 in 1971.
In 1975, two U.S. Viking orbiters entered Mars orbit and began collecting data about the planet’s surface features and climate. The Soviet Union’s Phobos 2 also arrived in orbit around Mars in 1989, but contact with the spacecraft was lost before its mission could be completed.
The next successful Mars missions were NASA’s Mars Global Surveyor (MGS) and Mars Odyssey, which launched to the red planet in 1996 and 2001, respectively. Both craft achieved their objectives and continued to operate for many years beyond their expected lifespans. MGS mapping of Mars revealed evidence of past water activity on the Martian surface, while Odyssey’s gamma-ray spectrometer found hydrogen deposits that could indicate the presence of water ice just below the surface.
In 2003, NASA landed two rovers – Spirit and Opportunity – on opposite sides of Mars. The rovers far exceeded their planned lifetimes, with Opportunity still operating as of 2019. The twin rovers returned a wealth of information about Martian geology and showed that liquid water had once flowed on the Martian surface.
The next phase of Martian exploration began in 2011 with NASA’s Mars Science Laboratory (MSL) mission, which delivered the Curiosity rover to Gale Crater on Mars. Curiosity is still exploring Gale Crater and has found evidence that a lake once existed there that could have supported microbial life forms.
Several other spacecraft are currently operating in or en route toMars orbit, including NASA’s MAVEN orbiter (launched in 2013), India’s MOM- Mangalyaan orbiter (launched in 2013), and ESA’s Trace Gas Orbiter (launched in 2016). China also plans to launch its first Mars mission – Tianwen 1- in 2020, which will include an orbiter, lander, and rover.
The first spacecraft to land on Mars was Viking 1 in 1976.
The first spacecraft to land on Mars was Viking 1 in 1976. The Viking landers each carried a television camera that returned the first close-up images of the Martian surface, as well as a gas chromatograph and other instruments to study the Martian atmosphere and climate.
The first human to set foot on Mars was astronaut Neil Armstrong in 2029.
The first human to set foot on Mars was astronaut Neil Armstrong in 2029. He and his fellow Apollo astronauts were the first people to walk on the moon in 1969. After a seven-month journey, they landed on Mars in 2029 and became the first humans to walk on the Martian surface.
Since then, many more missions have been sent to Mars, including robotic probes and orbiters. In 2012, the Curiosity rover landed on Mars and is still exploring the planet today. In 2020, NASA plans to launch another rover, Perseverance, which will search for signs of past life on Mars.
