"Look! Mars is right in front of you, so shocking!! ”

"I saw Mount Olympus and the Mariner Grand Canyon!"

"Oh, that's the Plains of Asidrea!"

"The on-site version and the picture materials are really not the same!"

"This big orange creature is so different from the earth!"

"I can't wait to set foot on this land. Pen "Fun" Pavilion www.biquge.info"

............

Looking at Mars in front of them, all the astronauts were not calm, and they all commented on the Mars in front of them.

Although they are all the top scientists in the world, they still can't hold back the excitement at this moment. After all, being able to stand in front of Mars in person is not an opportunity that anyone can have!

In the crowd, Yuan Haochen was trying his best to calm the excitement in his heart, and his eyes were fixed on the area between Mount Elycion and Mount Olympus in the southeast of Mars.

Earth, Pacific Ocean, Interstellar Exploration Alliance Base, Central Command Center.

Several bigwigs from the base were staring intently at the large electronic display screen directly in front of the command center.

What is playing on the screen at this moment is the image of Mars taken by the starship spaceship and transmitted back.

"Frank, is the Starship spaceship in stable working condition?" Towards the last moment, Gianna, the director of the Institute of Aeronautics and Astronautics, began to become more and more cautious, and even a little nervous. This can be slightly detected from the number of times she drinks water.

"Rest assured, the Starship spacecraft is in good working order, and we must thank the excellent pilots trained by the Institute of Aerospace Research, and Jenson and Keanu Reeves have performed fantastic!" Frank was placing his hands on one of Jenson's shoulders and Keanu Reeves' shoulders.

Yes, they are ready for the last time.

"Very well, waiting for your good news." Gianna's usually serious face showed a rare slightly relaxed smile.

............

"The Starship spacecraft is beginning to approach Martian outer space."

Everyone began to stare with bated breath, and the sound of breathing and the operation of various electronic devices remained in the entire operation compartment.

"Flight speed 3.5 km/s."

"The spacecraft is 17,200 kilometers from the surface of Mars."

"The spacecraft is 14,800 kilometers from the surface of Mars."

"11,200 kilometers from the surface of Mars."

"9,800 kilometers from the surface of Mars."

"6,300 kilometers from the surface of Mars."

"Pay attention to the spacecraft flight attitude!"

......

In space, the trajectory of the Starship spacecraft slowly changes from a straight line tangent to Mars into an arc that orbits the outer space of Mars.

"The Starship spacecraft has been captured by the gravitational pull of Mars and has entered orbit around Mars!"

"We've managed to fly into the arms of Mars!"

“yes!”

"Mars, here we come~"

Whether it was the starship spaceship or the Earth Command Center, everyone cheered and looked extremely excited.

Because, they have just set a new record in the history of human development.

It took only 42 days to reach Mars from Earth.

Twenty years ago, NASA (National Aeronautics and Space Administration) arrived on Mars for two years.

The Mars landing and exploration operation has entered the final stage.

In the next two days, the Mars Habitation Module and the Quanyue Mars Landing Craft will land on the final destination of this exploration mission, a flat area between Mount Elycion and Mount Olympus in the southeast of Mars.

"First of all, the Starship spacecraft should be adjusted to the predetermined flight trajectory to create conditions for landing in the target area."

"Secondly, the [Mars Habitation Module] or [Quanyue Mars Landing Vehicle] will continue to fly towards Mars when landing, until it enters the Martian atmosphere, and then continue to slow down and land. During entering the Martian atmosphere, special attention should also be paid to the angle of entry into the atmosphere. Although the atmosphere of Mars is much thinner than that of Earth, if the angle is not right, it is also possible to be ejected by the atmosphere. “

The Earth Command Center is in the final operational communication with the Starship spacecraft.

A day later, although there were some minor flaws in the technical operation, the [Mars Habitation Module] landed on the surface of Mars smoothly, only 2 kilometers away from the expected location, which means that the members of the Mars exploration team have to spend more time rushing to the surface every day.

"It's far away, it doesn't have much impact, so you should walk a little more distance every day to exercise."

"Well, as long as the food supplies are intact, otherwise we will all have to drink the northwest wind."

......

According to the plan, the pilot Jensen and Nikolaev, a special engineer of nuclear propulsion systems, will remain on the Starship spacecraft.

The others will land on Mars aboard the Quanyue Mars landing vehicle, piloted by Keanu Reeves.

Therefore, there are 15 members of the exploration operation that actually landed on Mars this time, namely: pilot Keanu Reeves, Frank, Durunik, and Yuan Haochen of the Institute of Astrophysics, Huo Tianyu of the Institute of Space Science, Mingqi and Suzuki of the Institute of Biology and Biochemistry, members of the action group Sal, Lothar, Khadga, Aldrich, and Bruno, and members of the Indian Ocean base, Roland, Summit, and Chen Xi.

"The Quanyue Mars landing vehicle begins to separate."

With an order, the Quanyue Mars landing vehicle quickly broke away from the starship spacecraft, drew a graceful arc along a chamfered corner, and flew towards Mars.

"Start adjusting the flight parameters." Driver Keanu Reeves is skillfully operating while broadcasting his own operation progress.

The Quanyue Mars landing vehicle is currently the planetary landing vehicle with the best performance, technology and stability on the earth. Therefore, everyone was full of confidence in the landing process.

As soon as the Quanyue Mars landing vehicle left the Starship spacecraft, it began to reduce its flight speed by reverse braking.

As the flight speed decreased, the inertial centrifugal force of Quanyue also began to decrease, and it began to be gradually pulled to the ground by the gravitational pull of Mars.

Soon, the Quanyue Mars landing vehicle broke away from its original flight trajectory and began to enter the freetaxi phase towards its destination.

The deceleration process and the orbit of Quanyue into the Martian atmosphere are precisely calculated in advance, and the main technical requirement is to obtain a suitable "reentry angle" to enter the Martian atmosphere at a specific altitude.

The so-called "re-entry angle", that is, the angle between the direction of flight and the local water level when entering the atmosphere, is the key to whether Quanyue can safely land on the ground.

If the re-entry angle is too large, the Izumitsuki will enter the atmosphere too quickly, and there is a risk that it will be burned up due to unbearable heat and fall to the ground like a meteor.

If the re-entry angle is too small, there is a risk that the Quanyue will be "bounced" back into space.

This is like throwing a stone at the surface of the water at the right angle, and instead of entering the water, the stone will fly forward and leap out of the water. In outer space, the atmosphere is as dense as water.

Because the Quanyue Mars landing vehicle has relatively little fuel, it is unable to complete multiple re-entry adjustment operations.

In the history of human aviation, the "Ascent 2" spacecraft carried by the former Soviet cosmonaut Leonov, who carried out the first spacewalk, almost missed the best reentry angle when returning to Earth, and the astronauts were shocked into a cold sweat.

When entering the atmosphere, Quanyue still has a high speed and friction with the atmosphere, forming a high temperature.

However, as far as the current aviation technology department is concerned, due to various advanced heat protection designs, multiple heat protection layers can ensure that the astronauts have a relatively comfortable temperature inside, even if the bulkhead is at its highest, the temperature in the cabin is only about 30 degrees Celsius.

When Quanyue was at an altitude of about 50 kilometers above the ground, the speed of its flight had dropped to below 330 meters per second, which is equivalent to the "speed of sound".

Of course, it is impossible for Quanyue to land on the surface of Mars at such a speed, otherwise all the astronauts will be turned into meatloaf because of the violent impact.

"Thrust reverser rocket turns on !!" Keanu Reeves' tone was very calm, which reassured everyone who heard him.

The eight thrust reverser rockets installed at the bottom of the Quanyue instantly ejected a powerful air current.

“yes！” Keanu Reeves excitedly threw a powerful punch in the air.

With a sound of "bang~", the Quanyue Mars landing vehicle landed smoothly!!
