On Mars, located in the eastern part of the Tharsisbulge plateau, there is a 4,000-kilometer-long canyon system with a maximum depth of more than 7 kilometers, with extremely steep and complex terrain. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

For earthlings, the Grand Canyon is already a formidable and spectacular natural spectacle. However, compared with the canyon in front of Yuan Chen, the Grand Canyon in the United States is far inferior.

This is the Vallesmarineris, the largest canyon on Mars and the veritable largest canyon in the entire solar system.

On a numerical scale, Mariner Canyon is 10 times longer and 5 times deeper than the American Grand Canyon on Earth.

Geologists speculate that the cause of the formation of Mariner Canyon may be closely related to the formation of the nearby Plateau of Thalcis.

The Plateau of Tarsis is home to Mount Olympus, the largest volcano in the solar system. The rocky features on the cliffs of Mariner Canyon and on the surrounding plateau indicate that the area experienced volcanic activity, which was formed by continuous lava flows.

During the first billion years of Mars, as the Tarsis Plateau was gradually uplifted by lava, the surrounding crust was constantly stretched and torn apart, and finally fractured to form the huge Mariner Canyon in front of Yuan Chen.

"It's better to see than to hear!! I already feel my feet shaking! “

Trunik simply stood at the edge of the Mariner Canyon, looking down at the abyss beneath his feet, and couldn't stop marveling.

"Do you remember the Grand Canyon where the two of us went?" Yuan looked at the other side of the Mariner Canyon and remembered all the experiences he had when he dealt with NASA a year ago.

From identifying the area where the mysterious meteorite target is located, assembling the Mars scientific exploration team, to departing from Earth. In the blink of an eye, it has been nearly 10 months since Yuan Haochen arrived on Mars.

“what？ How can the Grand Canyon of the United States and the Mariner Canyon be compared!! You look at the bottomless here, from my feet to the bottom of the valley, there is at least 6 kilometers of distance. "We are now the first earthlings to experience the majestic scenery of Mariner Canyon. Can you believe it? In the future, it will definitely become a tourist attraction for the people of the earth. ”

"Indeed, it's hard to appreciate this magnificent scenery without being there."

Although Hara had also seen the photos of Mariner Canyon taken by the European Space Agency's Mars rover before, how could those pale pictures be the same as the real feeling of stepping on the edge of the canyon.

With the launch of the Mars scientific research base construction project, in the foreseeable future, the human footprint will gradually cover the entire solar system.

Hara is convinced that more large bases will be established on every planet in the solar system.

At that time, such magnificent extraterrestrial natural landscapes as Mariner Canyon and Mount Olympus (the highest mountain in the solar system) will surely become a tourist attraction for people on earth.

However, today Hara and Trunik did not come to Mariner Canyon for fun (Mariner Canyon is located not far from the Martian Life Pod camp).

They came here to complete their last scientific mission on Mars, to investigate the interior landscape of the Mariner Canyon, and to control the Martian drone to sample and measure information in the canyon.

Mariner Canyon is indeed too long and deep, and with the capabilities of this Mars scientific exploration team, it is unrealistic to carry out very detailed scientific exploration on it.

Due to the steep terrain, places like Mariner Canyon cannot be reached by ground rovers. Therefore, the Martian drone has become the best choice.

"This Martian drone looks stupid!!"

Trunik removed the Martian drone from the rover and kept complaining about the clumsy guy.

The wings of the Martian drone are at least 60 centimeters, they are made of composite, glass or carbon fiber, and have a mass of less than 0.45 kilograms.

Since Mars' gravity is about 38% of Earth's, its actual weight on Mars is only 0.45 kilograms.

"The Martian atmosphere is so thin that only gliding drones with a huge wingspan can barely fly." Hara explained, "Keanu Reeves and Khadgar used it to survey the crater where the Source of Creation was located. Except for the inability to flexibly control the direction and shoot in the air, the other performance is quite good. ”

Trunik patted the wide wingspan of the Martian drone, and then said with a smile: "It's only this stupid guy." ”

"Let's get started." As he spoke, Durukik placed the drone on a suitable take-off trajectory.

"Let's go!!"

Yuan Haochen shouted, pressed the start button of the remote control in his hand, and the Martian drone immediately swooped towards the depths of the canyon with its wings trembling.

"Turn on Intelligent Flight Mode."

The Mars drone has an intelligent driving system and the ability to independently judge obstacles, which can safely and effectively avoid most dangerous areas.

When the Martian drone disappeared from the field of vision of Yuan Chen and Durunike, they could only operate on the video screen on the display screen, which was synchronized with the camera on the drone in real time.

"There are several canyons that merge into the Plains of Chris, and this should be the Kasai Canyon and the God of War Canyon......"

"These teardrop-shaped 'islands' at the end of the canyon are most likely the topography eroded by the current."

"After Mariner Canyon was formed, perhaps hundreds of millions of years ago, there was a strong current that changed the topography here.

"Do you think there could be signs of life at the bottom of the canyon?"

"God knows, but Mingqi will definitely be interested here."

"We're going back to Earth soon, and these tasks can only be handed over to the Martian science team in the future."

With the cooperation of Durunike, Yuan Haochen controlled the drone to shuttle back and forth at the bottom of the Mariner Canyon.

This feeling reminded Yuan Haochen of the model airplane toys he played with when he was a child.

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

There is still one month left before the Mars scientific exploration team returns to Earth.

In the last month, the Mars scientific exploration team has finally completed all the scientific research projects in the Mars exploration program.

This Mars scientific exploration operation has achieved outstanding results that have surprised everyone, and this operation will surely be recorded in the history of the development of human civilization and shine through the ages.

The only regret is that the Mars team was unable to take any of the core components of the Source of Creation with them.

However, the Mars science team has collected a large number of scientific research samples on the [Source of Creation] in accordance with the requirements and recommendations of the Earth science team.

Therefore, this operation can also be regarded as a full load.
