Let's go Mars
Why should humans travel in the universe? Why should humans go to Mars and other planets? We can collect data with unmanned space probes and make the universe a reality here on Earth in our worldview, in our self. That's not enough. Humans want information directly through their senses and thus make the world a reality. We have no choice. We have to go out into the universe. We have to take possession of planets to make them a reality.
The great challenge for our journeys into space is gravity. This mysterious force that we don't actually feel, which holds everything together, which prevents us from getting lost in the universe, but which also makes it difficult for us, to leave Earth.
We humans can only travel in space on a small Earth. In a spaceship that offers us everything we need to live. Because only when we live does reality emerge from the information our senses provide. We need air to breathe, food and drink, exercise, social life, and not to forget sex. Our spaceship must offer all of this if we're going to be traveling in space for months, perhaps years. So it has to be huge, not a small capsule like the ones rockets currently take us into space in.
WE NEED A GIGFACTORY IN SPACE
In orbit around the Earth, at an altitude and at a speed where gravity is still present, but at which it falls around the Earth, like satellites or the International Space Station - in weightlessness
Because gravity doesn't play a role in the construction of the Gigafactory in orbit, the statics are very simple. It only needs to be inherently stable. It must be airtight and provide a habitat for the people assembling our spaceship. The materials for the Gigafactory and the spaceship, as well as the supplies for the people, can be delivered using rockets we have.
The same applies to the spaceship. It can be built completely differently in zero gravity. It doesn't have to withstand the forces acting on Earth and during launch. It can begin its journey into the universe with little fuel. Travel to Mars or perhaps even to another solar system will become possible.
By the way, structures in space in zero gravity will be constructed as spheres. The sphere is a maximally stable shape. The spaceships of the trade will also look neither like saucers, nor rockets, nor ships. They will be spheres in which we travel in zero gravity.
We will make the journey to Mars in a space sphere.
We will build this space sphere in a spherical gigafactory in Earth's orbit. From there, we can easily set off with our space sphere to the moon, Mars, and beyond.
