Science and technology painting aerospace city

Science and technology painting Space City is as follows:

1. Draw a semicircle first and draw the glass cover of the spaceship.

2. Draw an ellipse under the semicircle to represent the main body of the spaceship.

Draw a semicircle under the ellipse, and the shape of the spaceship will come out.

4. Draw a diagonal line on the ellipse and a dot on the edge to decorate the spaceship.

Space city, the dream of human beings moving to outer space. In the vast space, there are "high-rise buildings" that run around the clock, and tens of thousands, hundreds of thousands or even millions of people on earth work and live in them.

Everything you need to work and live in this behemoth is readily available. The environment is elegant, the trees are shaded, the bridges are flowing, the frogs are singing and the birds are singing ... it's simply paradise. This is the future space city.

The rapid growth of the earth's population leads to the rapid expansion of cities, the decrease of cultivated land and serious urban pollution. With the development of space technology, it is predicted that the establishment of a space city to live and work in space will become a reality in 2 1 century. At that time, you may be lucky enough to become a new citizen of Space City and live and work in the space world.

Human exploration of building a space city. For a long time, people have always had the idea of building a space city in space outside the earth. 1926, tsiolkovsky, the originator of human space technology, imagined that one day in the future, human beings would establish settlements in space around the earth.

He imagined that the weightless environment in space could produce artificial gravity through rotation, and the indoor temperature and humidity could be suitable for plant growth through manual control, so that plants could be planted in greenhouses. He boldly predicted: "Choose the crops with the biggest harvest, and under the best growth conditions, every inch of land on the space farm may be enough to feed space immigrants."

Maybe you will ask, isn't the space city a space station? In fact, the space city envisioned by scientists is different from the space station. Their main difference is that the space city, as a space settlement, should be self-sufficient, first of all, self-sufficient in food. At present, the daily necessities on the space station are all transported from the ground.
