Despite Henry''s argument, every country is selfish. Who is willing to hand over his country''s elite troops to the Williams Empire? What''s more, the annual cost of this 100000 joint force is huge. Should each country share it equally?

    Henry looked at the faces of the people and knew that his idea of setting up the "Wei Yuan" joint force was too simple. Henry couldn''t help laughing at himself. It was for everyone''s sake. After the establishment of the Weiyuan united forces, the countries of the whole Weiyuan system could greatly improve their right to speak to the outside world. However, all countries were full of speculation and defense about the Williams Empire, and they were obviously unwilling to agree to the establishment of the Weiyuan united forces.

    Others kindly sent troops to help the Williams Empire, but in the end, they annexed their own troops. What would these countries think? At this time, if we want to push forward this plan, it will undoubtedly destroy the relationship between Williams Empire and the other 14 countries!

    Henry thought about it and said, "well, I don''t think you want to. In that case, forget it! Then I''ll send my troops back to all countries! Thanks for the help of all countries in this war. I will give 50 billion Weiyuan to show my gratitude and distribute it to all countries according to their contributions! For those who were killed or injured, the Williams empire will make up for them separately! "

    When the presidents heard this, they were very surprised and thought, it''s great to send troops to "make soy sauce" to get so much money!

    And Henry did it with a purpose.

    These countries get money this time and have a good taste. Next time, if Henry asks them to send troops, they will certainly send more troops. Virtually, the Williams Empire had the armed forces of the other 14 countries. In the Williams empire is not really strong, the power of the United Nations 14 can make European and American countries have a little fear of the Williams empire!

    After sending off the presidents of 14 countries, Henry began to be addicted to the research and development of artificial intelligence.

    Meanwhile, Henry is keeping a close eye on SpaceX''s moon landing plan. The manned spaceship used for landing on the moon has already been built, named "Zeus" spaceship. The spaceship is mainly divided into two parts: the main body of the spaceship and the lunar module. When the spaceship stops in the lunar orbit, the lunar module separates from the spaceship and begins to land on the moon. After completing the mission on the moon, the lunar module returns to the lunar orbit, combines with the spacecraft, and finally returns to the space station!

    When Apollo 11 landed on the moon in 1969, it adopted the three module landing mode, with the command module at the top, the service module in the middle and the lunar module at the bottom. The way to land on the moon is basically the same. After the spacecraft reaches the lunar orbit, the lunar module leaves the spacecraft and goes to the moon. However, limited by the technical conditions at that time and considering the weight and fuel, the lunar module had to be thrown away to reduce the weight after it returned to the spacecraft. Then the service module will provide power to return to the earth. In the end, the service module will be thrown away, only the command module will return to the surface of the earth.

    Today is different from the past. After 37 years, the Zeus spacecraft uses nuclear fission and graphene solar energy as the power source, which is enough to ensure the energy supply of the spacecraft. It is no longer necessary to throw away the lunar module, which is a waste!

    On July 15, SpaceX held a press conference to announce that the manned lunar landing project will be launched on July 20.

    The news shocked the whole world.

    Because so far, only the United States has successfully landed on the moon! If SpaceX can succeed, it is of great significance!

    Countless people are looking forward to the early 20th.

    Five days passed quickly.

    The launch site of the Zeus spacecraft is located at the SpaceX launch center in southern Somalia, which is located on the equator, where the earth''s rotation speed is the largest, which can save fuel for the rocket. SpaceX company plans to send 10 astronauts in the past, and these 10 astronauts have taken the first generation of gene evolution medicine developed by gene umbrella. Their body strength has reached 1.5 times that of ordinary people, and their resistance to cosmic rays has been enhanced, so they can better adapt to space life!

    At 09:00 a.m. southern Somali time, SpaceX successfully launched a heavy rocket code named "falcon 8" at the southern Somali launch center to lift Zeus into the sky. The rocket is a two-stage rocket. The first stage uses liquid fuel, and the second stage uses nuclear fission to ensure that the Zeus will be put into lunar orbit at the fastest speed.

    In fact, SpaceX has developed a plasma rocket thruster, but at the beginning, the plasma thruster was very slow, producing only 5 Newtons of thrust. If it is used in the short distance voyage of the moon, it is not as fast as other propellers!

    But don''t underestimate the plasma thruster.

    As early as 1998, deep space-1 was launched by the ion engine. Its impulse is 10 times that of the liquid rocket It consumes 100 grams of xenon propellant every day. When the engine is running at full speed, the speed will increase by 25-32 meters per hour every day. It eventually worked more than 14000 hours, more than all previous conventional rocket engines combined.

    The birth of plasma thruster shortens the time from 250 days to 39 days, maybe even shorter!!!

    There is no doubt that SpaceX company has a very deep research in this field. Zhang Fulin, a retired NASA astronaut, is now the main director of SpaceX''s plasma engine. He is the first Chinese American professional astronaut of NASA, with a quarter of Chinese descent. He completed his PhD in applied plasma physics at MIT in 1977. After graduation, he has been engaged in the research of plasma thrusters, and is one of the most authoritative experts in the world in this field! In 2005, he retired from NASA and founded Ad Astra Rocket Company. SpaceX company did not hesitate to acquire the company. Finally, Zhang Fulin and other talents were included in SpaceX company!

    The gravity of the moon is 16 times that of the earth, while the gravity of Mars is slightly more than 13 times that of the earth.

    The next goal is Mars.

    The rocket successfully sent the Zeus spacecraft into outer space and flew to the moon.

    The average distance between the moon and the earth is 38400 km. It took more than three days for the United States to land on the moon, and SpaceX plans to complete it in only one and a half days!

    Thirty one hours later, Zeus reached lunar orbit. The next moment, Zeus will send a lunar module to the moon.

    The exciting moment has finally arrived!
