With the start of the engine, Li Ling thought again, and the power of the engine began to increase slowly. Finally, when the power of the engine increased to 20%, the plane began to slide forward slowly.


    However, at this time, the engine of the aircraft continued to increase thrust. Finally, when the engine thrust increased to 100%, the aircraft finally taxied forward quickly. Finally, when the speed of the aircraft reached the take-off speed, the speed of the aerospace aircraft suddenly decreased. Obviously, at this time, the crew, The engines of the space plane have been shut down.


    After all, this first test was just a ground taxiing test, so the plane didn''t pull up until it reached the take-off speed.


    When the aircraft stopped at the starting point again, the crew of the aircraft conducted a self inspection of the aircraft again. After the self inspection had no problems, Li Ling''s crew started the engine again and turned on the pulse detonation engine power of the aircraft to the maximum at once.


    Finally, when the speed of the plane reached the take-off speed, Li Ling and his crew did not turn off the engine this time, but pulled up the plane and rushed to the sky.


    As the speed of the aircraft becomes faster and higher, the altitude becomes higher and higher. Finally, when the speed of the aircraft reaches subsonic speed, it will not increase any more.


    At this time, Li Ling''s crew immediately carried out self inspection of the aircraft. After all, the next test flight is much more dangerous than the previous test flight.


    Because the next test flight will be supersonic and hypersonic. Although it will not fly out of the atmosphere, it will only be tested at the suborbital altitude at the edge of the atmosphere, but the risk factor is much higher than that at subsonic speed.


    Soon the aircraft''s intelligent system completed the aircraft''s self-test, and did not find any problems. All the data of the aircraft are very perfect!


    Then, Li Ling and his team continued to increase the thrust of the aircraft engine. Naturally, the speed of the aircraft became faster and faster. Finally, the speed of the aircraft soon exceeded the speed of sound.


    And the speed is getting faster and faster. Finally, when the speed of the aircraft reaches five times the speed of sound, the altitude of the aircraft has also reached the sub orbital altitude. As long as the speed of the aircraft is increased again, the aircraft can cross the atmosphere and enter the universe.


    However, the aircraft did not continue to accelerate. On the contrary, the speed of the aircraft began to decrease and the altitude began to decrease slowly. Finally, when the speed of the aircraft decreased to subsonic speed, the flight direction of the aircraft also changed again and flew towards the space center.


    When the plane finally returned to the Aerospace Center and landed on the runway, people on the whole ground cheered. After all, this is not an ordinary aerospace plane, but the largest aerospace plane developed by human civilization.


    Therefore, the people on the ground are naturally very happy when the first flight test is successful.


    In addition to being happy, the ground crew on the ground will not forget their responsibilities. They will immediately check the overhead plane to see the situation of the plane after its first test flight.


    Therefore, the ground crew immediately began to tow the overhead aircraft on the ground to the hangar with a tractor and began to conduct an all-round inspection of the aircraft.


    After all, after this test flight, the next step is to make a real atmospheric flight, so they must ensure that the plane is safe.


    Two days later, the phoenix-5 aerospace plane had been thoroughly inspected, and the next day, it had an atmospheric test flight, and the test flight was also very successful.


    At the same time, with the successful atmospheric test flight of this aerospace aircraft, the mass production of this aircraft also began. Only more than ten days later, the aircraft was manufactured the next day, and the test flight began immediately.


    As the flight test continued, at this time, everyone also had a certain understanding of this aerospace aircraft, so they put their focus back on the test of the space fighter.


    After all, compared with this super large space plane, although the space plane is very important, the space combat capability still depends on the real combat weapon platform.


    At this time, Zhao Feng and his crew finally flew the space fighter and returned from Mars to near the lunar orbit.


    It can be said that the first test flight of the space fighter has been basically completed, and a large number of valuable data have been obtained. However, compared with the Mars orbit data obtained by Zhao Feng, in fact, the data of the fighter itself is not so important.


    After all, with these data, human civilization will have reliable data to support it if it wants to land on Mars.


    In fact, for landing on Mars, both Tiangong technology and the earth''s space agencies with strong Aerospace strength have long wanted to go.


    However, due to the limited volume and range of the previous space plane, the range of the space plane is not enough for the space plane to go back and forth from Mars.


    And the risk factor of using an aerospace plane to go to Mars is also very large.


    After all, the space plane is just an air and space vehicle, which is not enough to undertake the mission to Mars.


    But now it''s different. With the space fighter, compared with the space plane, the space fighter has strong defense and powerful force, so it can naturally carry out the ability to go to Mars.


    Most importantly, because the gravity of Mars is much smaller than that of the earth, but larger than that of the moon, and because the atmosphere of Mars is thin, with the ability of space fighters, we can still take off from Mars into space with our own power.


    Because of this, today''s Tiangong technology has begun to land on Mars.


    After all, in the plans of Tiangong technology and Qin Lao, when alien civilizations come to the solar system, the best way is to keep them out of the asteroid belt, so the status of Mars is naturally very important.


    After all, Mars is the closest planet to the asteroid belt, so for the safety of human civilization, Qin and others decided to build a large military base on Mars within 20 years to protect the safety of the earth.


    Of course, in addition to Mars, in the asteroid belt itself, it is natural to establish a military base, because compared with Mars, the asteroid belt is the main battlefield of future and alien civilization and the focus of building various defense facilities.


    However, with the existing scientific and technological strength of human civilization, it is still impossible to establish a base directly in the asteroid belt. Mars must be used as a transit station, so we should build a base on Mars first
