The universe is something that we can touch, feel, sense, and detect. It has many living components like stars, moon, planets, galaxies, cloud dust, and light. It has millions and billions of stars and galaxies. These stars and planets in the universe are very far apart from each other in real. The spaces present in-universe between planets and stars have hydrogen atoms and dust particles.
It has the presence of many radiations too like light, heat, magnetic fields, and high energy particles. The universe is huge and it is said by scientists that it is expanding day by day. The universe was small when it was created. The galaxies are moving apart from each other expanding the space.
Mars is the fourth planet from the sun and also the second-smallest planet as mercury is the smallest planet in our solar system. Mars is on the name of a Roman god of war and also known as the red planet. It has a reddish color appearance on its surface due to the presence of iron oxide. Mars is a terrestrial planet with a thin atmosphere. Surface features are quite similar to that of the earth like valleys, deserts, and polar ice.
How Long Does It Take To Get To Mars?
Mars is quite similar to the earth, it is half the diameter of the earth. The surface area of the mars is only slightly less than the dry land of the earth. The density of mars is less than the earth. The volume of mars is 15% less than the earth and its mass is 11% less than the mars. The gravity of mars is about 38% of the earth.
The distance between mars and earth is about 393.85 million kilometers. It takes almost six to seven months to reach march. The radius of the earth is 3,389.5 km with a surface area of 144.8 million km². The sun is about 227.9 million kilometers. It has an orbital period of 687 days. The gravitational force of the mars is 3.721 m/s². It has its own two moons named Phobos, Deimos.

Why Does It Take That Long To Get To Mars?
The universe is consists of several elements like planets, stars, and moons. The distance between mars and earth is traveled by spacecraft. The scientists first observe the complete movement of the mars as it revolves around the sun and rotates on its own orbit too so, they have to wait for a perfect launch time. The spacecraft has to be launched at the right time and at the right launch window to increase the success rate of the mission.
The time period can be reduced but there are a couple of problems associated with it. Firstly, to increase the speed of the spacecraft more fuel is needed for which the weight of the spacecraft has to be increased which means more expenses. Secondly, in space spacecraft follows the “First Law of Newton”. It states that an object is at rest or motion until an external force is applied to it.
Unlike in movies, it is shown that if the engine gets off it will stop moving but it is not the same in real. When the spacecraft’s engine is turned off it will still move in a straight line at a constant speed until any external force is applied to it. When spacecraft enter the mar’s atmosphere this may change the speed of the spacecraft. The gravity of the mars is used to slow down the spacecraft, but if the speed is more then its gravity will not be enough.
There are many space agencies and countries that are trying to reach mars and find favorable living conditions similar to the atmosphere of the earth. The scientists are finding life on the mars like the presence of water, oxygen, and other gases like on earth.
