Many associate the notion of the giant leap to humanity with the small step taken by Neil Armstrong on the moon, while NASA's astronauts and chemical engineers, as well as astronaut Donald Petit, disagree that the revolution actually took place much closer to Earth.

"The first step on the moon was not the giant leap in human history, but the Earth's orbit," he wrote in 2012.

The first step in reaching orbit about 400 kilometers from Earth requires half of the total energy needed to reach the surface of Mars.

The distance between the earth and the moon is simple compared to the distance we need to cut to reach the Earth's orbit.

The cost of the first step is flexed in the amount of gravitational force.


Physicists argue that saving one penny of the total cost depends on Earth's attempts to get your spacecraft back into orbit.

The gravity of the earth controls the surface of the earth, which means that 80-90% of the current missile mass must be disposed of by burning energy-generating materials to lift the rocket into space. According to Petit, this means that its stability will be low and unstable, and this will leave no room for transporting astronauts, food and equipment.

Despite these shortcomings we are fortunate.



"If the radius of the Earth is larger than it is now at a certain rate, we will not be able to make any rocket that can launch into space," says Pittit.

Betit began the calculation using the Tsilkovsky missile equation, to determine this ratio.

Suppose that a 96% missile design is propulsion material and a 4% rocket block is the practical limit for vehicle launch engineering.

With the choice of hydrogen and oxygen mixtures, the most active and effective driving chemical that can be used in rocket engines.

By applying these numbers to the Tsiolkovsky missile equation, we can convert the output of the escape velocity to the planetary radius.

According to this equation, the radius of the planet will be about 9680 km «6670 Earth radius».

If the diameter of our planet is larger than its current size by 50% - while maintaining its own density - we will not be able to invade space, at least not using missiles.

First, in this case, no current space transfer technology will succeed and will not be as efficient as the rockets currently used, and we must invent modern techniques that can overcome gravitational forces.

Several proposals for such techniques were inspired by science fiction, some of which were tested while others were successful.

The second point is to consider the establishment of a launch base on the moon as an axiom, as the rate of escape on the moon about 21.3% of the rate of escape speed on the ground.

While the launch of a rocket from the ground requires a lot of fuss and preparation, the moon still lacks much equipment.

Although a Cape Caneveral base on the moon is elusive, it is achievable with the development of 3D printing techniques as well as processing of raw materials.

To that end, we need to extract most of the material from the moon or nearby space objects, such as asteroids and comets.

That is, we can use the moon to serve as a gas station that processes its stock of ice water into a hydrogen and hydrogen energy.

In other words, the earth, as Petit puts it, controls its hold on humanity. Our invasions into space have been able to overcome this grip, and there is still a possibility of liberation.
