Technology Bigshot Chapter 558: :’Orion’ airborne on Mars]
……
"What news?" Ren Hong asked curiously.
"The American Noah has just entered the high-altitude orbit of Mars and sent the news back to Earth. NASA then announced the news and its follow-up actions, according to the brief message from the headquarters." Shockley said and looked at the time, It added: "According to the time on board, 53 hours later, the American crew of 'Noah', Scovo and Jackson, will take the 'Orion' spacecraft for the first manned Mars landing."
Speaking, Shockray sighed: "If there is no accident, the first human to land on Mars will be an American, but I am still a little unwilling. The first man on the moon was robbed by the Americans, and the first man on Mars also It is really uncomfortable to be robbed by them, our current level of space technology is obviously stronger than that of the Americans.”
"It's just a false name, what's wrong with it." Ren Hong smiled, seeming not to care.
But Shockley didn't think so: "That said, this is an achievement that will definitely go down in the history of mankind, and it has a huge impact. The footsteps of Armstrong, the words of one small step for mankind, one giant leap for mankind, It is widely circulated among all human beings. This time I don’t know how Americans will show off.”
Ren Hong said: "What is real influence? Real influence requires real strength as support. We are pragmatic. We are here to seek truth, not to seek fame. You have to figure out this. Point, Ari. Besides, the title of the first person on Mars was taken off by the Americans, but there are more first titles waiting for us, Jupiter, Saturn and their moons, as long as the strength is there, these first The gold content of the title will only be higher than Mars, but not lower, but the most important thing is that we are not here to get a false name, understand, risking danger and suffering dozens of times of acceleration and deceleration.”
"It would be nice if the old beauty's 'Orion' had something wrong and fell." Shockley muttered.
As soon as Ren Hong heard this, his originally pleasant smile turned into a serious expression, staring at Xiao Kerui and admonishing in a solemn tone: "Ari, I don't like your idea, it's not good. The height of civilization, any interstellar pioneer is great, no matter who the country is, he not only represents his country but also the human being. Even if he doesn't say it is so tall, he can't curse others behind his back with such narrow thinking. When something goes wrong, we can ignore rejection even when we have the ability to lend a helping hand. This is our right, and we don’t need to blame ourselves. But also we have no right to interfere with others. What others do is their business. , we ourselves must abide by the principles we should have.”
Ren Hong's tone was not very serious, but Xiao Kerui was still embarrassed and scratched his head not knowing how to respond. At this moment, the public frequency broadcaster on the ship sounded:
"All units and all crew members, please note that the last 45 minutes countdown, the spacecraft will perform the last acceleration, all crew members please stop all related activities immediately..."
Ren Hong glanced at the broadcaster, and said with a sad face: "Oh, it's time to torture people again, let's go boy, what are you doing, hurry up and get the nest ready for a long sleep, Do you want the acceleration to stick you to the wall?"
Speaking, Ren Hong got up and walked away. Every time the spacecraft was about to accelerate, the entire spacecraft was full of complaints. The spacecraft was about to accelerate for the last time. It stands to reason that everyone should cheer. , at least this is the last time to be tortured by acceleration, it is true.
But as long as you think that after the acceleration is over, you will also need to decelerate 15 times in the next time, so that when the spacecraft reaches the range of the gravitational field of Mars, the speed drops to the value range of the departure stage from the earth, which is another 15 times. Torment, thinking that there are 15 more times, no one can cheer.
Ren Hong is bored thinking about this kind of thing that he spends money to make himself suffer, just like a real masochist.
Having said that, although there are 30 tortures, it is not unrewarding. The spaceship that Ren Hong and the others are in can also continue to slightly accelerate for a long time like the "Noah", but the corresponding price is 200 Many days were wasted on the voyage that could not be done, and if Ren Hong and the others traveled to Mars according to the relative distance between the earth and Mars before departure, it would mean that it would take more than 800 days to travel to Mars. will reach Mars.
30 tortures can buy more than 700 days of precious time, and it's worth it no matter what.
America doesn't have the chance to be tortured.
45 minutes later, the front engine on the "Mars Express" started, and hundreds of thousands of lasers were irradiated on the light sail. The spacecraft, which was slowly decelerating, accelerated again.
The reason why the spacecraft has a very small slow deceleration at this moment is because of the solar wind. The "Mars Express" did not put up the light sail, and the front engine stopped the energy output. The solar wind will naturally take advantage of the huge area. The light sail forced the spacecraft to slow down, and he hesitated to use the third layer of the light sail to obtain energy from the sun during this period, so the multi-layer light sail could not be put away.
After the front engine operates, part of the thrust generated offsets the resistance from the solar wind and begins to accelerate forward...
……
June 25, 2028. Mars High Orbit, "Noah" Onboard Time: 15:36.
"9...8...7..." A crew member controls the "Noah" while reading the countdown, the "Orion" spacecraft at the head of the spacecraft, Scovo and Jackson are getting ready.
"...2...1 hull separation!"
On the quiet Mars mooring orbit, the spacecraft "Orion" and "Noah" were officially separated, and the "Orion" spacecraft carrying two crew members who landed on the planet's surface began to cut into the atmosphere of Mars.
The spacecraft entered the Martian atmosphere at a speed of 930,000 kilometers per hour. The outside of the hull quickly became hot and deformed. This is a normal phenomenon, but it is not as serious as the earth, because the atmosphere of Mars is thin and the gravity of the planet is not as good as that of the earth. The "Orion" spacecraft entered the Martian atmosphere at super high speed. Due to atmospheric friction, the temperature of the heat shield outside the hull was almost the same as the temperature of the sun's surface, reaching more than 1450 degrees Celsius. Fortunately, there is a heat shield to protect the interior of the spacecraft. The temperature is only about 20 degrees Celsius of normal temperature.
Over time, the speed of the first stage of the Orion spacecraft dropped by thousands of kilometers per hour. The spacecraft continued to descend, and the height drop became smaller and smaller. At this time, a huge parachute was opened, and the spacecraft further decelerated.
At this moment, the reverse thrust nozzle of the "Orion" spacecraft has been adjusted, but the spacecraft's landing speed is still very fast. If it hits the surface of the planet, it will also result in the destruction of the ship.
The height difference is getting smaller and smaller, and it has dropped to the height of 3 digits. Just as the spacecraft was about to collide with the surface of Mars, the three sets of nozzles spurted out flames in a frenzy, instantly creating a sky of dust in the Pezos Heights, and the reverse thrust constantly offset the speed of the spacecraft.
In the end, the "Orion" spacecraft was only a few tens of centimeters away from the surface of Mars. The flames of the three sets of engine nozzles disappeared in an instant. Once the engines were turned off, the spacecraft that lost thrust was pulled by gravity on the spot and collided heavily with the surface of Mars. , and then stopped moving.
The two astronauts in the spacecraft felt a relatively strong vibration before returning to stability.
"Arrived?" Scovo said suspiciously, but his teammates did not respond, and he answered himself: "It should be there!"
The two looked at each other, stunned for more than ten seconds, and the next moment was excited and wanton laughing.
