# How Far Is Space From the Ground? Discover the Answer Here!

Space is a fascinating topic that has intrigued humans for centuries. People have always been curious about the vast expanse of the universe and what lies beyond the atmosphere of our planet. The question that comes to mind is – how far is space from the ground? In this article, we will take an in-depth look at this question and explore what scientists have to say about it.

## What is Space?

Before we delve into how far space is from the ground, it is important to understand what space is. Space is the vast expanse that lies beyond the Earth’s atmosphere. It is a vacuum that contains planets, stars, galaxies, and other celestial bodies. The temperature of space is very low and it has no air, which makes it impossible for humans to survive without adequate protection.

## The Definition of Space

The definition of space has been the subject of much debate over the years. According to the United States Geological Survey (USGS), space begins at an altitude of 50 miles (80 kilometers) above the Earth’s surface. This is known as the Karman line, named after the Hungarian-American engineer, Theodore von Karman. However, there is no global consensus on where space begins, and different organizations have different definitions.

### How Far Is Space?

The distance between the Earth’s surface and the beginning of space can vary depending on the definition that is being used. According to the USGS definition, space is approximately 50 miles (80 kilometers) from the ground. However, NASA defines space as beginning at an altitude of 62 miles (100 kilometers) above the Earth’s surface.

Furthermore, there are other definitions of space that stretch even further. For instance, the Fédération Aéronautique Internationale (FAI) defines space as beginning at an altitude of 62.1 miles (100.335 kilometers) above the Earth’s surface. The important thing to note is that the distance between the Earth’s surface and space is not fixed and can vary depending on the definition being used.

## How Far Can We Travel into Space?

Now that we have established how far space is from the ground, the next question is – how far can we travel into space? The answer to this question depends on the technology being used and the purpose of the space mission. Currently, the farthest humans have traveled from Earth is to the Moon, which is approximately 238,855 miles (384,400 kilometers) away.

Unmanned spacecraft, on the other hand, have traveled much farther. NASA’s Voyager 1 spacecraft, launched in 1977, has traveled beyond our solar system and is currently located more than 14 billion miles (22 billion kilometers) away from Earth.

## Why Do We Study Space?

Studying space is crucial for expanding our understanding of the universe and the laws that govern it. There are several reasons why we study space, some of which include:

• Discovering new planets and celestial bodies
• Exploring the possibility of life in space
• Better understanding of climate change on Earth

## Conclusion

In conclusion, the distance between the Earth’s surface and space can vary depending on the definition being used. Currently, the distance is approximately 50 miles (80 kilometers) according to the USGS definition. Studying space is crucial for advancing our understanding of the universe and the laws that govern it. Through space exploration, we can discover new planets, better understand climate change, and explore the possibility of life beyond Earth.
