How Long Does It Take to Get to Mars?

Greetings Challenger!

Welcome to the world of space exploration where humans have been fascinated by the red planet, Mars, for centuries. Mars has been a topic of discussion and research since ancient times, with both scientists and the general public wondering about the time it would take to reach the hostile planet.In this article, we will dive into the details and help you understand how long it takes to get to Mars, the journey’s duration, distance, and the latest developments in space exploration. So without further ado, let’s explore the red planet!


The idea of traveling to Mars started with the Mariner 4 and Mariner 7 missions launched by NASA in 1964 and 1969, respectively. Since then, space exploration towards the destination has taken place with significant advancements in technology, but the question still remains: how long does it take to get to Mars?The travel duration from Earth to Mars highly relies on several factors, including the spacecraft’s speed, distance, the position of Mars concerning Earth, and more. Therefore, the journey’s duration can vary from months to years.In this article, we will break down the factors that determine the duration and give you answers to the burning question, how long does it take to get to Mars.

The distance between Earth and Mars

The distance between Earth and Mars varies due to several factors, including their orbits, which are the paths they take around the Sun. Earth completes one orbit around the sun in approximately 365.25 days, while Mars takes around 687 days, which means that their orbits vary in time.The distance between them is minimum when they are positioned closest to one another, and it’s called the “opposition.” At its closest, Mars is approximately 33.9 million miles (54.6 million kilometers) away from Earth. This distance is the minimum required to start a journey towards Mars.

Factors That Affect Travel Duration

Several factors determine the time required to reach Mars. The most influential factors include the spacecraft’s speed, the position of Mars concerning Earth, and the spacecraft’s technology.

The spacecraft’s speed

The spacecraft’s speed is the essential determinant of the travel duration. To reach Mars, spacecraft must escape from Earth’s gravity while reaching the necessary velocity to orbit and travel towards Mars. Currently, NASA’s spacecraft reach a top speed of approximately 25,000 mph (40,225 km/h) to reach Mars.

The position of Mars concerning Earth

The most optimal position between Mars and Earth for a spacecraft to launch would be when they are closest to each other. This position is the opposition and occurs once every two years.

The spacecraft’s technology

The spacecraft’s technology is an important determinant of travel duration. Spacecraft technology has significantly advanced since NASA’s first Mars missions. The latest technology, such as NASA’s Mars Reconnaissance Orbiter and Mars 2020 Perseverance Rover, use AI, machine vision, and reliable Internet of Things (IoT) devices to explore the planet.

How Long Does It Take to Get to Mars?

Achieving a distance of approximately 33.9 million miles (54.6 million kilometers) to reach Mars takes between 150 and 300 days, depending on the characteristics of the spacecraft, the speed of the spacecraft, and the position of Mars concerning Earth.

The History of Mars Exploration

Mars has been a topic of research and exploration for centuries. While our understanding and knowledge of the planet have increased, space exploration of Mars’s planet began in the 1960s. The following missions have contributed to our understanding of Mars:

Worldwide Missions

Several other countries have also launched missions towards Mars. The following are some international missions towards the planet:

The Challenges of Traveling to Mars

Traveling to Mars presents several significant challenges that one must overcome. The harsh environment, distance, and lack of resources are just some of the issues that space travelers face. However, with the advanced technology and ongoing scientific breakthroughs, the goal of human exploration of Mars is closer to becoming a reality.

Mars – The Destination

Mars has been called Earth’s twin planet due to its environmental similarities. The planet’s features make it a good candidate for a second home if scientists can address the environmental challenges.
