The earth and Mars are so far apart, how to solve the interstellar traffic between them?

Scientists conceived a relay scheme: it was transferred to the spacecraft several times, mainly because direct flight could not carry enough fuel. The general idea is to build three space stations in the space between the Earth and Mars, namely, the near-earth orbit space station, the free point space station between the Earth and Mars and the Mars orbit space station. These three space stations are both transit stations and gas stations. Its traffic line will be like this: take the space shuttle from the earth to the first station-the low-earth orbit space station, and then transfer to the second station-the freedom point space station, where you will refuel, and then take off to dock with the survey spacecraft. This kind of spacecraft uses nuclear power and sails in a fixed orbit. When the spacecraft approached Mars with a transshipment spacecraft, the transshipment spacecraft left the spacecraft and flew to the third station, the Mars Space Station. After arriving at this station, transfer to the Mars lander and land on Mars, thus landing on Mars. It can be seen that traveling to Mars is much more complicated than landing on the moon, which is time-consuming and requires a lot of money.

Interestingly, maybe it fell from the sky, and Mars has two satellites orbiting it. "Phobos" is 20 kilometers in diameter, and it takes 8 hours to make a detour; Phobos has a diameter of 1 1 km, and it takes 30 hours to make a circle. Both satellites have an atmosphere and low gravity, so the transshipment spacecraft does not need to land here, just dock. These two small satellites are natural space stations where humans can build camps.

American scientists put forward a plan to immigrate to Mars, called "Louis space settlement". The idea is to send a huge spaceship to Mars, which will hold 65,438+0,000 people. This ship will not land on the surface of Mars, but will be suspended on it. The spacecraft carries all kinds of life on the earth. It will rely on the energy recovered from space to keep running, and it can use local materials on Mars. The spacecraft is equipped with thousands of solar panels to make full use of the sun's irradiation to generate energy.

In the early years of 2 1 century, it is possible to send Martian houses and equipment to Mars, and then it is possible to send astronauts to Mars. However, the distance between the earth and Mars is very long, and the journey takes more than half a year. Loneliness in space is another problem. However, there is always a way for mankind to overcome these obstacles. 2 1 century, a trip to mars will eventually become a reality. The expectation of the universe

The development of science not only provides a new basis for human beings to understand the unknown world, but also raises new questions about the established theory, thus promoting the continued development of the theory.

The discovery of pulsars proves the speculation of Landau, a famous physicist in the former Soviet Union, after discovering neutrons as early as 1932: there may be a neutron star with high density, which is almost entirely composed of neutrons. The discovery of pulsars and pulsars in the crab nebula quickly made scientists realize that pulsars are just neutron stars that people were looking for decades ago.

Pulsars prove the existence of neutron stars and test the theory of star evolution. The discovery of pulse binary stars proves the prediction of gravitational waves; The discovery of interstellar molecules is of great significance to the study of the origin of life. Water molecules and ammonia molecules are closely related to life processes. Formaldehyde, hydrogen cyanide and propionyl molecules are essential raw materials for the synthesis of amino acids, so it is speculated that there may be amino acids in space. 1969 a meteorite fell in Australia, and scientists found more than a dozen amino acid molecules. By analyzing the rock samples retrieved from the moon, trace amino acids were also found. Amino acid is the main raw material of protein and nucleic acid, and life is the way of existence of protein Group. Therefore, the discovery of interstellar molecules gives scientists good reason to speculate that in many parts of the Milky Way and extragalactic galaxies, the process of life formation that began about 3 billion years ago on earth is under way. Perhaps in some places, the civilization created by rational life is more advanced than that created by human beings on earth. There are still many unsolved mysteries in the universe, and people are expected to continue to explore.

Human beings are constantly understanding nature, and the development of science and technology has promoted the deepening of human understanding of nature. The course of human understanding of the universe reflects this deepening process. Dialectical materialism holds that the universe is infinite, and the course of human understanding of the universe can also explain this infinity. With the development of science and technology, human exploration of the universe will never stay within the scope of the entire galaxy. Outside the total galaxy, there must be a vast world that humans don't know today. Let's give full play to our wisdom and make our contribution in the human struggle to explore nature.
