Du Xingyu doesn''t have time to reply to these private letters, because the space plane Xingzhou is about to test launch!

    The first launch will be unmanned. It is expected to stay in space for 48 hours and then return to the ground.

    After return, it will be overhauled. If everything goes well, it will be launched a second time.

    The second launch is a crucial link. This time, two astronauts will travel to space on Xingzhou and fly around the earth in low earth orbit to detect and collect various data.

    The launch site is still in Jiuquan Satellite Launch Center.

    This is a secret launch. No one knows except the core members of NASA and Xingyao company!

    In the ground command center, Du Xingyu looked at the computer quietly. It showed that all kinds of data were within the standard value. He looked very calm.

    But many people can''t calm down. This is the first time they have participated in such an important and cash space research mission.

    "I''m so excited!" Wang Wei whispered with Lv Liang. "We didn''t graduate and took part in such a task. No one has this resume!"

    "Yes, last time I launched a rocket with Du Xingyu in the school square. This time I''m going to play real, it''s still an air plane!" Lv Liang has always been calmer than Wang Wei, but his mood can''t be calm when he participated in this level of mission for the first time.

    "Attention, there are thirty seconds left." Du Xingyu read into the microphone.

    "Ten, nine, eight... Three, two, one, fire!" with his order, the engine of the space plane began to start.

    Some space planes cannot take off by themselves and must rely on rockets to help them fly into space. But the star boat has a three in one engine set and can fly out of space independently.

    Now it is the take-off state. The first operation is the air turbine. The power generated by it makes the space plane fly into the blue sky!

    "The speed of flight is close to the speed of sound!"

    "When the speed reaches six times the speed of sound, start the ramjet group and continue to accelerate!"

    "The air is thin, about to fly out of the atmosphere, start the rocket engine group and start the space navigation mode!"

    In the command center, Du Xingyu has been tracking the status of the Xingzhou in real time.

    "Xingzhou has entered low earth orbit."

    Xingzhou entered low earth orbit safely, and everyone celebrated.

    Du Xingyu said, "it''s hard for everyone. Now we''re on duty in turn. If there''s an accident, we''ll inform you at any time. In 47 hours, we''ll be ready to recycle the Xingzhou!"

    "Yes!" they began to take turns on duty, observing the state of the Xingzhou 24 hours a day.

    Xingzhou is flying silently in low earth orbit. The scientific research instruments carried on it keep transmitting data back to the ground.

    Forty eight hours later, the Xingzhou still flew steadily. According to the established plan, the ground gave it instructions to land.

    This is the third time that Du Xingyu has participated in the recovery of space equipment. He commanded and completed the task with ease and familiarity.

    "Except that the thermal insulation coating of the Xingzhou is worn, everything is in good condition! It can carry out the task again!" the inspectors reported.

    "OK," said Du Xingyu, "repair the thermal insulation coating and prepare for manned space!"

    "Start!"

    The team was busy again. A week later, three days before the launch of SpaceX manned dragon spacecraft, Xingzhou launched its second low-key launch.

    This time, there are two brave astronauts on the Xingzhou. They will drive the Xingzhou into space and stay in space for a whole week to test the performance of the spacecraft and space flight related data.

    All this is unknown to the outside world.

    Their focus has been on the launch of SpaceX''s new Falcon rocket. In order to demonstrate their strength, this time SpaceX will launch Falcon 9 and manned dragon spacecraft, which will also be broadcast live on TV and Internet!

    Global audiences can watch it in real time! In order to publicize, they also specially invited the media of various countries to broadcast.

    At 15:20 local time, about 3:20 a.m. Chinese time, the manned dragon spacecraft carrying two American astronauts and a dinosaur doll was ready to take off.

    The new Falcon 9 rocket is already on the launch pad, and media reporters are talking to astronaut Bob benken.

    Bob benken is the commander of the operation. He has carried out six spacewalks and has rich experience.

    "Mr. benken, what do you want to say about the launch of the manned dragon spacecraft?" the reporter asked.

    Bob benken replied, "I think this launch is of great significance. This is the first time in American history that a private company has sent astronauts into space, not the space agency!"

    "It can be seen that the commercial aerospace technology of the United States is developed. Believe me, I will successfully complete the mission! And you, every free American, will have the opportunity to wear the same aviation suit as me and walk in space!"

    Bob benken''s speech excited the audience, and countless Americans cheered and celebrated in front of the TV.

    On the webcast, American netizens were also very excited.

    "Bob, good job! I wish you success!"

    "SpaceX is great! It will realize my dream of going into space!"

    "Falcon 9 and manned dragon spacecraft are the world''s top!"

    "Ha ha, our aerospace technology in the United States ranks first in the world!"

    "This is much more powerful than the Rockets in China before. Can rockets make people walk in space?"

    ……

    In Huaxia, some netizens stayed in front of the computer and watched the live broadcast.

    At the moment of seeing Falcon 9 successfully ignite and take off, a large number of viewers brushed words such as "666" and "beef beer".

    At the same time, some people are regretting: "if only SpaceX were a company in our country!"

    "When can we do this?"

    "Du Xingyu doesn''t broadcast live anymore. It''s boring! Go to bed and watch it tomorrow!"

    In the United States, in the manned dragon spacecraft launch Mission Command Center, musk blushed. Everyone could see that he was very happy!

    "2 minutes and 30 seconds, the first stage rocket separated and recovered successfully!"

    "9 minutes and 28 seconds, two-stage rocket separation, successful recovery!"

    "In 12 minutes and 00 seconds, the manned dragon spacecraft separates from the secondary arrow and enters space!"

    "This is astronaut Bob. The spacecraft has separated successfully. We will dock with the international space station in 19 hours!" Bob benken''s voice came from the communicator.

    "Congratulations! Congratulations to us too!" Musk shouted.

    The good news kept coming. Musk told his subordinates: "champagne, open champagne for me!"

    He danced excitedly while opening champagne. He can imagine how much praise SpaceX will receive when the manned dragon spacecraft successfully docked with the international space station!

    Stock prices soared, orders soared, state support... All this seems to be readily available!

    "Haha, this time we''re finally going to surpass Du Xingyu in China!" Musk hummed happily. He decided not to sleep until the manned dragon spacecraft docked with the international space station!

    At this time, the earth''s outer space, in addition to manned dragon spacecraft, spacecraft are sailing. The Xingzhou, carrying Chinese astronauts, is also sailing.

    "It is reported that we have entered low earth orbit and will arrive near the international space station in about 19 hours," reported astronaut Tian Qinghui on the Xingzhou.

    "Nineteen hours?" the ground command center calculated that at this time, it is likely to meet the manned dragon spacecraft.

    However, both spacecraft are flying in low earth orbit and must meet.

    "Meet and meet!" Du Xingyu is also happy to see its success. There is no need to keep it secret. If you meet, you will take the opportunity to announce a wave and save advertising expenses.
