    In the space base, the scientific researchers of Dayang Group are busy.

    The transformation of Venus is by no means as simple as it seems, and a series of data must be carefully checked.  The most important thing is the time, which must be accurate to 0.01 seconds!

    The revolution speed of Venus is 48 kilometers per second, and the attack speed of the rail gun is 500 kilometers per second. In order to pursue absolutely precise control, only the functions of the electromagnetic science part are used.

    Then there is the flying speed of the asteroid. The temporary flying speed is 52 kilometers per second, and it is catching up with Venus relatively quickly.

    ¡°Venus in this world has a diameter of 14,000 kilometers, an orbital velocity of 8.4 kilometers per second, and an escape velocity of 11.9 kilometers per second.

    At the last moment, the asteroid must reduce its speed from 52 kilometers per second to between 8.4 and 11.9 in order to be captured by Venus' gravity.  Of course, the distance to Venus cannot be too far, and it must be controlled within 30,000 kilometers.

    At this time, the distance between Venus and Tianyuan Star is more than 8,000 kilometers; when the asteroid reaches the vicinity of Venus, the distance between Venus and Tianyuan Star will be about 83 million kilometers.

    On a scale of 83 million kilometers, there are too many factors to consider when launching a railgun shell from Tianyuan Star to accurately hit a moving asteroid.

    The flight trajectory of asteroids, the deceleration effect of spacecraft and engines, the gravity of Venus, the gravity and interference of the sun on asteroids.

    Rail gun shells fly 83 million kilometers in the void, and they also have to consider the gravity of the sun - and when they were just launched, because they were too close to Tianyuan Star, they also had to consider the gravity of Tianyuan Star and even the moon's gravity.  When it reaches the vicinity of Venus, it will still be affected by Venus' gravitational pull.

    When launched, the speed of the rail gun shell is 500 kilometers per second; affected by the gravity of the sun, according to calculations, when approaching Venus, the flight speed will reach 547 kilometers per second.

    Finally, the rail gun projectile needs to trace an irregular curve, span one-sixth of the orbital distance of Venus, and hit the small ice planet.

    The diameter of the first ice planet is 800 kilometers. If the rail gun wants to destroy the planet with one shot, it must hit the bullseye, and the deviation cannot exceed 100 kilometers.

    According to the target calculation, it must be within 8 rings.

    And there is only one chance to attack, and if you make a mistake, the consequences are unpredictable.  Once an asteroid slows down, it has little chance to speed up again.  A runaway asteroid is likely to hit Venus head-on.

    By then, the land of Venus will have completely changed, if at all, and the force of the impact will be enough to reshape the entire planet. It will take tens of thousands of years to stabilize.  And after the impact, the location of resources on Venus that have been explored for more than two years will all disappear.

    If it¡¯s serious, if you say no accidentally, it will cause Venus to deorbit, which will be really troublesome.  At that time, the planets in the entire galaxy will be in regional chaos under the effect of gravity.

    According to scientific calculations, once Venus deorbits, there is a 30,000 chance that Tianyuan Star will detach from the sun, and then be gravitational slingshot by the gravity of other planets, until 300,000 years later, the planet will be directly ejected out of the galaxy.  , becoming a wandering planet.

    Therefore, when transforming the galaxy, there is really no room for mistakes.

    Rail gun shells need to fly a distance of 83 million kilometers - in fact, because the flight trajectory is an irregular curve, Venus will continue to move forward during this process, and the actual flight distance exceeds 85 million kilometers.

    During the flight, it is also affected by the gravity of the surrounding planets, and the speed of the cannonball is changing all the time.  During the entire process, the flight time of the artillery shell is approximately 45 hours.

    There are so many difficulties, but the time when the rail gun hits the target must be accurate to 0.01 seconds, and the bullseye only has a radius of 100 kilometers.

    This is truly the challenge of the century.

    ¡°It took two years to prepare for this shot, during which countless simulation calculations were performed.

    In the command center, various calculation data are displayed on the huge display screen, and various orbits appear.  A huge amount of data passed by like a waterfall, and even a master of Dongxu had no time to memorize all the data.

    The orbits of different colors displayed on the screen include the orbit of Venus, the orbits of three asteroids, the orbit of the starry sky cannon attack, and the evacuation orbit of the spacecraft.

    The time difference of ten days between the three asteroids is used as the reserved adjustment time.  No one can guarantee that this process will be completely smooth.

    Zhang Hao sat quietly in the live broadcast room on the ground and did not enter space.

    Zhang Hao knew very well that the pressure on the researchers was already high enough. Going there himself would not only have no effect on promotion, but would actually double their pressure.  Appropriate pressure is good??The relative speed was reduced to 9.5 kilometers per second, and the asteroid was completely captured by Venus.  (Note 1)

    At this moment, the steam from the asteroid rolled towards Venus.  In fact, at this moment, even if there is no rail gun attack, the asteroid will evaporate little by little and be absorbed by Venus within a thousand years.

    However, Venus does not have a magnetic field and cannot protect its atmosphere. The water vapor will be carried away little by little by the solar wind.

    The asteroid was captured by the gravity of Venus and revolved around Venus for a small half circle. At this time, the asteroid was just between Tianyuan Star and Venus.

    And at this moment, the cannonball of the starry sky cannon accurately hit the asteroid.

    "I saw the asteroid tremble suddenly, its surface collapsed rapidly from the direction of the attack, cracks spread rapidly, and a large amount of ice, dozens of kilometers in size, peeled off from the planet.

    The next moment, the entire planet suddenly collapsed and turned into endless pieces of ice.  Under the impact of the cannonball, a large amount of broken ice and rocky star cores quickly fell towards Venus.

    The entire asteroid fragment rushed into the atmosphere of Venus with huge kinetic energy.

    For a time, the atmosphere of Venus was lit up by meteors.  Crushed ice rubs violently with the atmosphere, and the temperature can reach over 3,000 degrees. Steam and hot air exhibit combustion characteristics.

    Because the structure of the asteroid is mainly composed of ice, and coupled with the impact of cannon shells in the sky, the collapsed ice itself is already densely covered with cracks. After entering the atmosphere of Venus, the violent collision caused a large number of ice cubes to break.  Atmospheric friction causes constant evaporation and collapse.

    Only less than 10% of the ice eventually fell to the ground.  However, because most of the ice is already very fragile and full of cracks, most of the ice breaks when it touches the ground, and has limited impact on the surface of Venus.  Only a little ice, and mostly fragments of the rocky core, have impacted the surface of Venus.

    Generally speaking, under the strict calculations of Dayang Group¡¯s technical staff, the structure of Venus has not been damaged.

    On the contrary, these broken ice and water vapor carry huge kinetic energy, which is the kinetic energy of an entire asteroid. This kinetic energy first caused the atmosphere of Venus to surge like a tsunami, and part of the atmosphere of Venus was directly knocked out of the planet and out of gravity.

    There are also some fragments that impact and drive the rotation of Venus.

    And the disturbed atmosphere gradually accelerated Venus.

    Five days after the impact, the speed of Venus's winds finally dropped below the speed of sound, and Venus began to rotate.

    And a large amount of ice entered Venus, causing the atmosphere of Venus to double in size. Endless water vapor crisscrossed the atmosphere of Venus, causing lightning and thunder.  Thick dark clouds appeared on the golden planet.  The temperature of Venus' atmosphere has dropped by a hundred degrees!

    ¡°But because the crust of Venus itself is in a molten state, coupled with the energy of the impact, the temperature is rising rapidly.

    (Note 1: Regarding the speed of planets capturing asteroids, I checked a lot of information, and the more I looked at it, the more confused I became. I always felt that the description was wrong. It seems that the speed of the two planets is not much different, rather than that one planet is slowing down. But no  Come around the corner~) (Remember this website address: www.hlnovel.com
