Giant craters between Mars, Mount Elycion and Mount Olympus. Pen fun and pavilion www.biquge.info

Frank, Minchi, Suzuki, Sal, Lothar, Aldrich and others have successfully reached the bottom of the crater with professional climbing equipment through the previously surveyed route.

"It's just ahead, let's hurry!" After a short rest, Frank pointed to the hollow of the deep valley at the bottom of the crater.

That's the ultimate goal of this exploration of Mars.

A large dark green rock about a kilometer in diameter was in the center of the crater's deep valley, shrouded in a dark shadow.

When they reached the bottom of the crater, they understood the cause of the dark shadow that had been hanging over the bottom of the crater.

It turned out that the terrain at the bottom of the crater formed a natural return air outlet, which caused the Martian air flow to increase at the tuyere, rolling up the dark dust at the bottom of the valley from time to time and flying all over the sky.

This, combined with the relatively little sunlight that can reach the bottom of the crater, makes it always a lingering dark shadow for astronauts or exploration satellites to look at from high altitudes.

"Oh my God, this guy is so much bigger than I thought !!"

The road at the bottom of the crater was not in good condition, and it took Frank, Sal and the others half an hour to reach the foot of this mysterious meteorite.

"The composition of this whole meteorite seems to be the same as that of the black and green part of the Chenchen meteorite!!"

"It's shocking, know what that means?"

"Could it be that this whole meteorite contains traces of ancient extraterrestrial life!" Dr. Minchi said as he looked at the mysterious meteorite with bright eyes.

"Far more than that, we are all meteorites combined with stable dark matter in front of us!" Frank added with some excitement, "I guess it's not just a natural meteorite!" There must be an amazing secret hidden behind it. ”

"Let's find out the truth!" Sal looked a little impatient.

"Sal, let's split into two groups and go around from each side." Frank suggested.

"Okay, this meteorite is estimated to have a circumference of five to six kilometers. We divided our troops into two routes, first made preliminary observations, and estimated that we would be able to meet again in less than an hour. ”

After deliberation, Sal led Lothar and Aldrich to the left of the meteorite, while Frank, Minchi, and Suzuki began to explore along the right side of the meteorite.

As the investigation continued to deepen, Frank's heart became more and more surprised.

"Is this just a coincidence? The mysterious shape of the meteorite is too regular. Frank seemed to sense something, and thought to himself.

Indeed, the slightly larger meteorites in the general universe are basically of different shapes, but the shape of this meteorite is very special.

After nearly half an hour of observation, Frank was surprised to find that the route they had traveled along the meteorite, that is, the shape of the edge of the meteorite, turned out to be an arc length with mathematical laws!!

Frank was keenly aware of this and began to do a number of calculations in his mind.

First of all, he selected one at intervals for punctuation, and determined the corresponding coordinate values in the unified system, and when he finally calculated the coordinates of these points in a unified manner, he obtained a very perfect elliptical image.

Yes, if there were no miscalculations, the arc Frank had just traveled was a quarter of a perfect oval.

To make further confirmation, Frank continued to select coordinate points for the second half of the journey, and then substituted the coordinate values of these points into the elliptic standard equation he had calculated earlier.

"Exactly fit!! The meteorite has a perfect elliptical shape!! ”

Frank has fully verified his conjecture.

However, apart from the mysterious shape of the meteorite, Frank made no other special discoveries along the way.

Although the shape of the mysterious meteorite is perfectly oval, the details of the outer wall of the meteorite are not so perfect, and it is covered with dense small craters.

"Maybe it's caused by the high temperature melting of the meteorite's surface in space or other external forces." As Frank observed, he guessed that these details were indeed consistent with the situation of the space meteorite.

"Don't you think something is wrong, Frank?" Dr. Minch's deep voice interrupted Frank's train of thought.

Along the way, both Mingchi and Suzuki have remained silent, and there has been little communication between the three.

"Something is wrong? Yes? Minki, what do you mean? Frank asked, confused.

"We've been walking for over an hour!!" Minki continued to prompt Frank Dao.

"Walked for more than an hour?" Frank frowned slightly.

"Ahh By the way, according to the plan, we should have met Sal and them a long time ago! ”

"Maybe Captain Sal was delayed on the road and walked more slowly." Suzuki guessed from the sidelines.

"It's unlikely, we're not going fast, and we're already three-fifths of the circumference of the meteorite." Dr. Minchi apparently also secretly calculated the standard equation for the shape of the meteorite.

"Quick, let's pick up the pace and go ahead and have a look!!" Frank said with a serious face.

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

In the Martian Habitation Module camp, Hara is giving Durunik a routine infusion treatment according to Dr. Minchi and Suzuki's instructions.

"Poof~" The airlock cabin suddenly sounded, and a person hurriedly walked in.

Take off the helmet, it's Khadgar.

"Something's wrong! Something went wrong!! Khadgar said anxiously.

"What happened?" Yuan Haochen and Huo Tianyu asked at the same time.

"Sal, Lothar, Aldrich, and the three of them suddenly disappeared while exploring the crater!!"

"What, all three of them are missing!!

This is really surprising.

"Have the Starship Spaceship send a message to everyone on the emergency call channel, telling Vice Captain Thrall that if they receive a message, they will immediately return to the camp to report."

"Okay, I'll contact Jenson right away!" Huo Tianyu immediately began to contact the starship spaceship.

"And you." After Khadgar and Huo Tianyu finished speaking, they looked at Yuan Haochen, this was the first time he had spoken to Yuan Haochen in a few weeks since Bruno's death.

"Now that there is a serious shortage of manpower, Captain Frank asked you to go to the bottom of the crater and search for Sal and them together.

"Good!" Yuan Haochen didn't say anything, and began to put on the spacesuit quickly.

Out of the camp, Yuan Chen and Khadgar boarded the rover together.

"Are you ready?"

"That's it!"

"Let's go!"

"Let's go!"

There were only Khadgar and Yuan Chenchen on the rover, but the atmosphere was not as tense as before.

Although there were not many words between the two, the tone was calm.
