The answer to this question is scientific and technical data It holds up.

to have someone else It looks like we still have time for that.

The power of rockets is used to counteract gravity.

Given the fact that the Earth pulls everything towards it with its enormous gravity, spacecraft must escape the influence of this force and reach space. a huge thrust they need it.

This is where rockets come into play. rockets, chemical energy into kinetic energy They transform and provide thrust at tremendous speed.

To escape the world 25 thousand miles or 40 thousand km Because it is necessary to go fast, this thrust is created and rockets overcome gravity and provide the necessary escape velocity.

One of the reasons rockets are so powerful is the fuels used.

in rockets solid, liquid or hybrid There are different types of fuel used, and they all have different advantages. Fuels burn under high pressure in the rocket engine, and the gases released during combustion are expelled at high speed.

In this way the rocket is actually Newton’s “For every action there is an equal and opposite reaction.” It obeys the principle and rushes forward. With the thrust, the spacecraft leaves the earth and reaches space.

Being in different phases is also a factor in transporting spacecraft.

Another important point about rockets that carry vehicles into space is their multi-stage design. Rockets usually consist of more than one stage, and each stage functions as the previous stage. He finishes and leaves.

They provide more efficient flight by gradually reducing the weight of the rocket. The first stage provides the greatest thrust to overcome gravity, while the later stages longer distances with less energy focuses on reaching there.

Why then aren’t other methods used?

Think of a balloon, a catapult or an electromagnetic rail system. If you understand these things a little bit, you can come up with many ideas, and they are all theoretically possible may appear.

However, the Earth’s atmosphere and gravity make most of these ineffective, or at our current level of technology, rockets do precision and reliability not offered.

Of course a new idea is new and high costs We must not forget that this is so.

It is unknown what the future holds, but today in the transport of space vehicles We’re still in the rocket.
