The ion engine of the six ships emits a light blue flame and gradually moves away from Deep Space.

Under the strong discouragement of the people, Yu Yifeng did not play in person this time.He was just standing on the observation deck of the Deep Space and watched these ships leave.

Half a day later, all the spacecraft, centered on the Titanz, successfully reached the "Dig 114" over the "Dig 114", about 15,000 kilometers above the surface.

They then begin to slow down to lower the orbital altitude.

If the plan can be successfully implemented, the five Leviathan spacecraft will enter a low-Earth orbit 1,000 kilometers above the ground to carry out remote remote control tasks of unmanned machinery.

1000 kilometers, equivalent to the distance between some satellites and the earth, the signal delay is still acceptable.

The Titanz stays in an orbit of 3,000 kilometers.

It will be responsible for the relevant data processing and provide the necessary fire support.

Titanz is still a bit large and is specifically designed for war.To maximize its combat capabilities, it looks like a spherical space fortress with a variety of sophisticated weapons.

But this complex structure also has some limitations... it, like Deep Space, cannot land on the planet.

"If Titanz gets too into the planet's gravitational well and wants to climb out, it's a little hard.It's its own ion engine, and it's not powerful enough."

“In this way, should we design a large spacecraft dedicated to climbing deep gravitational wells?”Yu Yifeng couldn't help but ask in the captain's room.

“You mean... the big ship that can land on the planet?”The cost of manufacturing is too high, it is not necessary!"

“This kind of ship, all the structures have to be redesigned, troublesome.”

The lily shook his head and said lightly, “You know, where gravity is big, you can’t use a curvature engine.According to our current theory, the spacecraft still has to jet in the opposite direction to obtain propulsion power.”

"The ion engine is ejected, is high-speed plasma, and in principle it is still the opposite direction of the jet... very low-end, isn't it?"How much gas is going to be sprayed by a hundred million tons of large spacecraft that wants to fly out of the atmosphere!”

Speaking of which, she smiled slightly, "So climbing the deep grit of gravity, the space elevator is already a good choice."

Yu Yifeng nodded: "This is also, using electric energy to convert potential energy, or is it very economical... So, some non-work quality promotion methods?"Is there any scientific progress?”

Lily thought about it and shook his head again: "The laser push is the mainstream of current research, and it has been partially successful."But the driving force is not big, and it is difficult to mention.Slight motion is the same problem...”

"No quality to push, the price/performance ratio is not good at all, we launch a large number of high-energy lasers back, but in exchange for the back seat force is so little... I think there is no working quality to promote, the possibility of replacing the ion engine is unlikely, unless there is a theoretical qualitative change!"

“Is it so difficult to push without work quality... well...” Yu Yifeng wai.

In this way, the scientists in front of them have made new discoveries.

Perhaps because of war, in the low-Earth orbit of space, there is scattered space junk, all around the planet to do high-speed motion.

These space junk is a very annoying thing in space engineering, because they have a certain probability of encountering a spacecraft and causing a major accident.They are more than ten times faster than a normal bullet, so the kinetic energy is much higher than the bullet.

Although human spacecraft have been reinforced in key parts, it is also troublesome to be hit by large space junk.

Therefore, the automatic defense laser of each ship is all in an open state.

"Space junk will not be produced naturally, it can only be man-made!"All scientists see space junk as they see a baby.

Then, in this pile of space junk, a spherical device similar to a communications satellite was observed, flying rapidly.

Its speed is about 7 kilometers per second.

One of the captains reacted extremely quickly, observing the satellite for a moment, and he immediately excitedly said: "Capture!Catch it!”

With the commander's order, a highly maneuverable "Uyan" emerged from the frigate and began to accelerate its flight and chase the satellite.

After approaching the satellite, the robotic arm threw out a soft material similar to the aerogel net to reduce the speed of the satellite.

The satellite was successfully covered, gliding a distance inside, and the speed finally dropped, and the spacecraft remained on par.

Then it was pulled back to the ship...

“Did you capture a satellite?”

Deep Space is 900,000 kilometers away from six spacecraft, and the images seen are three seconds delayed.So, 3 seconds later, Yi Feng received the news, and he frowned slightly.

If it is his, before capturing the satellite, it must be carefully tested to see if it is not working properly to eliminate some potential dangers.

So, from his point of view, the captain's approach is a little reckless...

But he didn’t say much.

900 thousand kilometers of distance, one by one, almost six seconds, this delay is still too much, inconvenient to command.Therefore, Yu Yifeng simply devolved most of his powers to the respective captains in advance, and let them grasp the decision-making within the safety regulations.

This mission is also an exercise for the group of soldiers.

In addition to the "Titan Z" captain is Xu Yunjin, the next "Livitan" captain is Zhao Yao, the other four are new captain.

In fact, it can not be said that it is a "new recruit", but the kind that has never fought and seen blood...

No way, can't always protect them, they have enough training, but the sense of crisis, mission experience is seriously insufficient...

After the satellite was returned to the spacecraft, the first inspection was carried out.

Its mass is about 560 kilograms, the core part of a small hole is played by some kind of weapon, and because of this hole, it has become a pile of space junk, and there is no signal to release.

“... the level of danger should be low, and in theory there would be no such thing as a bomb.”

After evaluating the risk, the scientists immediately isolated it with a robotic arm to analyze the specific performance.

The first analysis is the material system.

The results show that both metal and glass are the most conventional low-level space materials, such as titanium alloys, magnesium alloys, and glass steel.

Its level ... is even less than the Knicks civilization!

“These materials look familiar... well, I don’t mean we’ve used it before, have we used it before?”

“Is every civilization’s technology tree the same?”Some scientists are doubtful.

"To be light, you want a unique technology tree out... This kind of underlying technology, perhaps every low-level civilization is really similar."Only at a higher level, with more and more development directions, will the unique technology of civilization be formed...” They analyze and guess.
