The Challenge of Space Travel

Space travel is a journey or transportation in or through space. A clear boundary between the Earth and the space is absent. The International Aeronautical Federation adopted a height of 100 km from the Earth’s surface as a border between the Earth and the space. In order for the aircraft to fly at this altitude thanks to the action of aerodynamic forces, it is necessary to have the first cosmic velocity.

As soon as the mankind opened a window into space, humanity rushed into the unknown distance, and not only in dreams as before.

Space travel is still available only for some people and is too expensive. Two years ago, NASA has launched an ambitious project 100 Year Starship, which involves a gradual and long-term creation of a scientific and technical foundation for space travels.

This unprecedented program should attract scientists, engineers, and enthusiasts from around the world. If it is successful, after 100 years the mankind will be able to build an interstellar ship, and travel around the solar system on special trams. However, there are still some challenges that need to be overcome in order to space travel.

One of such challenges is that time and speed are relative. No matter whether the ship space is inhabited or not, it needs high speed to reach the stars, which is close to the speed of light. However, it will help solve the problem only during the flights to the nearest stars.

According to the relativity theory, the passage of time in two systems moving relative to each other is different. Since the space ship at large distances will be able to develop a speed very close to the speed of light, the difference in time on the Earth and the ship will be particularly large.

Another challenge is that space is not empty. Everywhere, there are the remains of gas, dust, and particles. When you attempt to move at speeds close to the speed of light, each atom faced with the ship is like a particle of cosmic rays of high energy. The level of radiation at such a bombardment will rise even when flying to the nearest stars. The mechanical action of these particles at such speeds is like the bursting of bullets. According to some estimates, every centimeter of a protective spaceship screen will continuously be fired at with a frequency of 12 bullets per minute. Clearly, no screen will sustain such an impact over several years of flight. To overcome this challenge, the thickness of the screen should be tens to hundreds of meters with the weight of hundreds of thousands of tons.

Hopefully, in future all the challenges of space travel will be overcome, which will allow the mankind to travel in space.

Space travel is a journey or transportation in or through space. A clear boundary between the Earth and the space is absent. The International Aeronautical Federation adopted a height of 100 km from the Earth’s surface as a border between the Earth and the space.
