The vast starry sky is boundless.

When navigating in space, it is easy to lose your sense of direction and degree.

Because if there is no reference object as a comparison, it is easy to feel that the spaceship is floating in the vast universe, and it will never reach the other side, as if it has neither advanced nor retreated, and has lost its sense of degree.

This feeling is like a person wandering in the ocean, if there is nothing around for reference, it is easy to get lost and lose the confidence and courage to move forward.

Fortunately, there is no shortage of 'lighthouses' in the universe.

In astrophysics, stars also have a lifespan, and when a particularly massive star reaches its old age, it will have a nova explosion, and the remaining mass is less than the Oppenheimer limit, and it will collapse into a neutron star.

The neutron star rotates very fast, and the strong radiation from the poles will form a stable high-brightness light, making the entire neutron star look as bright as fluorescence from a distance.

Taking the position of one or several neutron stars as a reference, it is possible to determine a general direction for interstellar navigation, and at least through the change of relative position, it can be calculated that it is moving, and there is no prohibition.

After a long journey, Qin Tian was not bored enough to count the stars, in fact, there was a lot of work to be done.

After passing through the wormhole, the position of the 'Tianyu O1' spacecraft is already very far away from the Milky Way, where is the planet Dastan? How far is the distance? Qin Tian first had to determine his position.

The second is that the Dastan civilization is about to be destroyed, so will it be other races and civilizations that will destroy them, or will the geological or climate change of the planet Dastan itself, and the harsh environment will lead to the destruction?

In the end, Qin Tian's family is old and young, and it is impossible to lose his life for a task, so even if he does a task, he must plan carefully and meticulously to avoid hanging up because of negligence.

Therefore, Qin Tian had a lot of things to be busy with.

"There are 200 million kilometers left from the planet Dastan!"

After loading the mission map package, the spacecraft's intelligent master control system finally completed the calculation of the position of the universe and planned the navigation route to the planet Dastan.

For a spacecraft that can fly with light, the distance of 200 million kilometers seems to be a long way, but when it enters the state of light, it will only take twenty minutes to arrive.

"Dad, the Dastan civilization is about to be destroyed, of course I can't rush directly into this planet to save people!"

"There are too few available intelligence materials, I must first find a position that can be attacked, retreated and defended, and then reconnoitre!"

Qin Tian called up the star map and looked for a nearby planet, and suddenly a planet larger than the mass of the earth made Qin Tian's eyes light up.

This planet is very similar to Saturn in the solar system, with multiple moons orbiting, and a large number of planetary rings composed of broken ice, rocks, gravel, etc., although the environment is harsh, but it is very suitable for hiding, and most importantly, it is not far from the planet Dastan.

The hiding place, of course, is to make the environment as complex as possible.

After making up his mind, Qin Tian immediately made a plan to hide.

If you want to take refuge in the highly moving planetary ring, you must have some necessary calculations, the most important thing is to fly near the planet, be able to be accurately captured by its gravity, and then enter the planetary belt, and keep the flight degree and direction consistent with rocks, ice and other debris, so as to avoid being knocked unconscious by these 'space junk'.

Soon, Qin Tian's simulation calculation determined that the plan was feasible, and immediately adjusted the spacecraft's course and power system thrust to make the spacecraft move forward at about 18 kilometers per second.

At the same time, in order to avoid being hit by interstellar dust and meteorites, and to deal with any sudden situation, Qin Tian turned on the power of the detection system, and electromagnetic and laser weapons were also ready.

Five minutes!

Ten minutes!

Before the spacecraft approached the planetary ring, Qin Tian began to constantly adjust its course and power output.

After a few minutes of tossing, the Tianyu spacecraft successfully 'hid' into the planetary rings full of various large and small meteorites, broken ice, gravel and other mixtures, and hiding in this 'big circle' around the planet, Qin Tian did not forget to keep the spacecraft's optical electromagnetic stealth system on.

After quietly hiding down, Qin Tian began to prepare for the observation of the planet Dastan.

Just as the Earth can support life, in the galaxy where Dastan is located, there is also a massive yellow dwarf star that is constantly nuclear fusion to scatter light and heat to the surrounding area, and bring a large amount of electromagnetic radiation.

At present, the volume of the Dastan planet is larger than that of the earth, although it also has an atmosphere, but Qin Tian has some abnormal air flow movements, and it is estimated that on the surface of the Dastan planet, there must be a lot of bad weather such as hurricanes, tsunamis, and sandstorms.

At the same time, Qin Tian also found that there were a large number of floating objects in the space space near the planet Dastan, and the metal detection reaction was very strong, which could not be ruled out as space junk caused by large-scale space activities.

"The fact that the human civilization on the planet Dastan is able to carry out space activities proves that their technological strength is not bad! But why haven't they seen a single normal satellite? The electromagnetic activity of the entire planet is also very small, is it that they are all dead?"

Qin Tian sighed with emotion, and in order to grasp more of the situation, he controlled the spacecraft to shoot a space probe.

This space probe, which uses electromagnetic catapult, is a small reconnaissance satellite of the dexterous type on the other side of the earth, and now it is used as Qin Tian's 'reconnaissance pioneer'.

The probe flew very quickly, because it itself was equivalent to a cannonball, shot by a large-caliber electromagnetic cannon, and after more than ten minutes of high flight, the probe approached the gravitational orbit of the planet Dastan, and under the gravitational action of the planet, there were some changes in course.

Qin Tian immediately remotely controlled the probe to make attitude adjustments, making the probe get closer to the planet Dastan, and then immediately began to carry out various explorations through the onboard equipment.

Conventional detection methods such as infrared/visible/synthetic aperture were of course used for the first time, and life detection, electromagnetic induction, etc. were also put into operation.

The probe soon began to send back data, and Qin Tianxian saw photos of terrain and landforms that were not particularly high-resolution.

Looking down from space, Qin Tian felt that the more he looked at Planet Dastan, it looked more and more like the Earth.

There are mountains, plains, and rivers, and even the ocean can be seen in the back photos, which is a living planet full of life at first glance, but it is very strange that it always gives Qin Tian a sense of lifelessness and no human activity.

"Damn, I can't be late, right? Why is it that such a big planet has no signs of radio-electromagnetic activity at all? Could it be that I received a fake mission?"

As soon as Qin Tian finished scolding, the meteorological data came back.

After the automatic analysis of the system using the Dvořák analysis method, the minimum pressure in the center of the airspace detected by the probe is 92o hPa, and the wind force has exceeded 24o kilometers.

In order to get more high-definition photos, see what is really going on on the ground of the planet Dastan.

Qin Tian controlled the space probe to continue to descend in altitude, even if he risked being smashed by space junk, he had to risk death to take pictures secretly.

After all, the lower the altitude, the higher the accuracy of space remote sensing imaging.

It's like a human being, even if your vision is normal, you can't see clearly if you're too far away, but you can see clearly when you're closer.

And the photo that suddenly lowered the altitude and suddenly took it back made Qin Tian stunned......
