"Tarth, calculate the remaining fuel of the ship and make a plan for the route to Planet Five."

"Captain Pang, at present, the spacecraft has 30% of fuel left, going to Planet 5 will consume 10% of the fuel, about 5% of the fuel will be consumed during landing, and at least 20% of the fuel will be consumed for take-off and return, if you land on Planet 5, you will not be able to perform the return mission."

Pang Xuelin said: "For the time being, we will not consider the take-off and return plan, if we can find Murphy on Planet Five, then use her shuttle to replenish fuel, and if we can't find Murphy, then hibernate on Planet Five and wait for rescue." ”

"Understood, Tass will make a flight plan right away."

……

Planet 5 is only about 10 million kilometers away from Planet 6, and this planet is located exactly on Lagrange L1, where red giants and Jupiters work together.

The so-called Lagrange point, also known as the translational point, is the five special solutions to the restrictive three-body problem in celestial mechanics. A point in space where a small object is under the gravitational pull of two large objects, at which point the small object remains essentially stationary with respect to the two large objects.

In the solar system, the famous Trojan Group asteroids are located at the Lagrange point between the Sun and Jupiter, in the same orbit as Jupiter.

Here, however, Planet Five's orbit is largely synchronized with that of the Jupiters.

It only took Pang Xuelin a week to drive the shuttle to the geosynchronous orbit of Planet 5, and then captured a geosynchronous orbit relay communication satellite left by Murphy.

"Captain Pang, the communication log on the relay satellite shows that on the day of landing, Murphy sent an encrypted message about Planet 5 to the Eternal Night via the relay satellite, and no information has been transmitted since then."

Pang Xuelin frowned, looked at the emerald-like planet covered with a large green patch below, and said: "First analyze the encrypted information, and then descend to the altitude to make an all-round observation of Planet Five, I need all the information of this star." ”

"Yes!"

Three hours later, all the information about Planet 5 appeared in front of Pang Xuelin's eyes.

Life exists on Planet Five.

This was the first message Murphy sent back to the Eternal Night via a relay communications satellite.

This is followed by a large description of Planet Five.

Planet 5 has a complete atmosphere, of which 24% is oxygen, 73.4% is nitrogen, 1.7% is argon, and the remaining 0.9% is carbon dioxide, hydrogen, ozone and other gases.

Planet 5 does not have oceans, but there are many large and small lakes and rivers.

Moreover, the overall trend of Planet Five's rivers is from north to south or from south to north.

The poles are covered with glaciers and plateaus, and the water of these lakes and rivers comes mainly from glacial meltwater at the poles.

The surface of the planet is covered with vast forests and grasslands.

The surface water is evenly distributed, and deserts are almost non-existent.

In addition, there are many wild animals that Murphy has never seen before.

"It's really strange, Planet Five is simply the most suitable habitat for humans, how could Murphy suddenly lose contact with the Eternal Night after entering?

Could it be that on this planet, Murphy has encountered some kind of irresistible and powerful creature?

But it's not very likely, even if some powerful creature attacks Murphy, it is impossible to block the shuttle's connection with the communication satellite in the air above the synchronous orbit.

Or was it a problem with Murphy's shuttle that caused the communication with the Eternal Night to be cut off? ”

Pang Xuelin couldn't help frowning.

"Tarth, does the encrypted message have the coordinates of Murphy's location when he landed?"

Pang Xuelin said in a deep voice.

"Yes. But ......"

"But what?"

But images sent back by Murphy show that the area where she landed was a meadow-forest zone, with a lake nearby. But according to the coordinates she provided, satellite photos show that there is only forest ...... in that area."

"How so? Could it be that there is a problem with the coordinates that Murphy sent back? ”

"I don't know, this requires the shuttle to map the global terrain for comparison, and then TASS can give an answer."

"Alright, Tarth, from now on, the shuttle maneuvers in the terrestrial orbit and maps the terrain of the world."

"Roger."

……

In the next few days, in addition to drawing a topographic map of the world, Pang Xuelin spent the rest of his time conducting a comprehensive analysis of the data of Planet 5 formed by the shuttle.

But no matter from which point of view, Planet 5 has a complete ecosystem, the natural environment is completely in a primitive state, and has not experienced any development of intelligent civilization.

"Tarth, it seems that we can only go deep into the interior of Planet Five to find the secret of Murphy's loss of contact."

Looking at the emerald-like planet under the porthole, Pang Xuelin said in a deep voice: "Let's go." ”

The shuttle flipped over deftly and floated down towards the dark green planet below.

Three hours later, the shuttle stopped a kilometer from the planet's surface.

What appeared in front of Pang Xuelin was a majestic green world.

The tall trees are nearly 100 meters short, and the height is even four or five hundred meters, and the branches and leaves spread out like umbrella covers.

Small trees cover an area of dozens of acres, and large trees cover an area of hundreds of acres.

Each giant tree is inhabited by countless creatures, and these creatures form a complete ecological chain.

Some trees have strange fungi growing on their bodies, and the spores that drift away with the wind swim among the trees.

There are huge flying birds, nimble monkeys, squirrel-like animals that look cute but have sharp fangs......

There are also giant pythons the size of buckets, fierce beasts with sharp fangs like tigers and leopards, and flying eagles with wings spread for tens of meters......

It's a vibrant, untamed world.

Pang Xuelin piloted the shuttle and flew around Planet 5 at an average altitude of about 1,000 meters.

Then he flew straight to the landing spot that Murphy had sent back.

"Captain Pang, what's wrong with you?"

Seeing Pang Xuelin's frowning brows and standing in front of the front window, Tas came up curiously and asked.

Pang Xuelin shook his head and said, "It's perfect." ”

"Isn't it nice to be perfect?" It's a great place to live. ”

Pang Xuelin shook his head and said, "The essence of the universe is to tend to chaos, but the essence of life is to pursue order and perfection. Tarth, do you think these newly-enlightened beings alone can form such a perfect ecosystem? ”。

Tas said: "Captain Pang, do you mean that there is an intelligent civilization on this planet?" ”

Pang Xuelin shook his head with a smile and said, "I don't know." ”
