Vol 3 Chapter 244 landing

In fact, it is not appropriate to describe it as a sparrow here, because in comparison, the two fighter jets are more like a slightly larger butterfly.

“Please do not get too close to Luna 2, lest the force field near Luna 2 cause unnecessary damage to the aircraft.”

The two fighter planes continued to circle, which seemed to be intentional. The closest position to the spaceship was already close to 100 meters away.

Because it was flying in the air, although the visible light stealth system was turned off on Luna II, the outer protection was always on, because no one knew if someone would have a convulsion and give them a missile.

It’s just that there is no need to glide in the air now, so the shape of the protective cover no longer has the shape of wings, and it becomes closer to the hull of the spaceship.

However, there is still a buffer distance, about 50 meters. You must know that this is a protective cover that can withstand the impact of micrometeorites and meteorites. The protective cover has no effect, let alone the spacecraft tens of meters away.

Her reminder was purely because she didn’t want the two planes to get too close to each other, resulting in a plane crash and fatal accident, which would affect Hua Guo’s cooperation.

At an altitude of 20,000 meters, even if you eject and parachute immediately, the chance of surviving is almost zero, let alone the greater possibility, and the plane hits the protective cover, which is no different from hitting a mountain. No, no chance to skydive at all.

Following Xiao Ai’s reminder, the two fighter planes stopped flying around, and quickly straightened their bodies and flew down.

It’s not that the two planes don’t know how to lead and accompany them, but that the Luna 2 is almost the same from the front to the rear, and it’s impossible to tell which side is the head and which side is the tail, so they can only fly downwards first. Speed, leading in the front.

At this time, Luna 2 also started up. Its huge body seemed to have completely escaped from Blue Star’s gravity, and slowly, like a tractor, it slowly fell towards the predetermined location.

In fact, in the field of aviation, although flying fast is not easy, it is definitely not as difficult as flying slow.

Although at the beginning of the birth of the aircraft, with the lift of multiple wings, the flight speed of the aircraft could be reduced to more than 100 kilometers.

But at that time, it was a propeller plane, and its top speed would not exceed 200 kilometers.

Now it has almost become the world of jet aircraft, especially fighter jets. For high-altitude and high-speed performance, the wing sweep exceeds 45 degrees, and the flying speed will never be lower than 500 kilometers. If it is lower, it will fall. .

Probably the only decommissioned American Panda fighter jet in the world, because of the variable swept wing, can transform itself into a straight-winged aircraft, capable of cruising in the sky at a speed of two to three hundred kilometers.

“Eighty kilometers per hour, is this an aircraft? Tractors are faster than it!”

The staff on duty at Jiucheng Airport, without the auxiliary system of radar, had to rely on primitive telescopes to observe the trajectory of Luna 2 bit by bit, and finally calculated its moving speed.

From the wine city to the capital, under the anxious gaze of everyone, Luna II slowly landed on the airport, where it was prepared.

After falling down, you can see its huge size. Its height is actually not that high, only about ten meters high, which is limited compared to those large planes, but its width is more than 25 meters, and its length is about 100 meters. .

As it fell, several armored vehicles with warning lights on, including fire trucks, had already surrounded the place tightly, and the warning tape with reflective film was also pulled for several hundred meters.

This is also what it should be. After all, it is something that came back from outer space. Although the items that entered the Blue Star through the normal way, they were basically sterilized by the heat generated by the friction of the air. There should be no virus. Such things can withstand high temperatures of thousands of degrees.

But Luna II is different, because its landing method is different from that of ordinary spaceships and meteorites, and its speed is far from the level of violent friction with the air.

And there is a protective cover outside. Although most of the time, the protective cover is invisible, but after entering the atmosphere, it will form a space shuttle-like wing, which can glide in the air, which can be regarded as greatly reducing friction.

Of course, the shell of Luna 2 and most of its structures were actually built in the vacuum environment of the moon. So far, no microorganisms or viruses have been found that can survive for a long time. Survive in a vacuum environment.

Yang Qing’s research on the lunar soil also proved that although there are some organic macromolecular components in the lunar soil, there is absolutely no sign of life, not even the legendary tardigrades that can survive anywhere .

However, just in case, Luna 2 mainly travels between the blue star and the moon. The situation on the blue star is extremely complicated. There are various microorganisms in the soil and air, which will inevitably pollute the moon. The cabin and shell of the God II.

The interior of the cabin is okay, the air and moisture are circulated, and the disinfection procedure can be completed during the circulation process.

There is not much to do with the casing, unless it is disinfected by liquid cleaning like car washing.

However, Luna II is still too big, and the liquid consumed by cleaning it, even water, is an unbearable pain in this small northwest city.

Besides, Yang Qing also looked down on this backward method of using liquid to clean.

The titanium alloy sandwich plate on the surface of Luna 2 has a metal airgel in the middle that acts as a support and has thermal insulation capabilities. Its thermal conductivity is extremely low, second only to vacuum.

The sandblasting coating on the outside is not only extremely smooth, but also has almost no wettability. Neither water nor organic solutions can soak it.

Except for mercury~www.readmtl.com~ of course, its wettability is completely a bug for metallic substances.

But here, even mercury can’t exert its sky-defying amalgam binding ability, otherwise, if a spaceship is afraid of a drop of mercury, it will become a joke like a Hollywood blockbuster.

The coating of the shell has a strong bactericidal ability, and there are no microorganisms at all, which can survive on it for more than a minute.

In the human world, generally speaking, the most harmful diseases are caused by viruses, but in fact, the survival ability of microorganisms and bacteria is much stronger than that of viruses.

Microorganisms can survive independently, and the DNA of their offspring can remain basically the same, and mutations are less prone to occur.

Viruses not only need a host to survive, but the DNA or RNA in the body frequently mutates, and even the original virus, after dozens of generations of mutation, has completely lost the characteristics of the tissue.

But even though Xiao Ai had already communicated with them about the situation of Luna II, they still chose their own way of handling it.
