"It's so fast, it's as fast as lightning, and now it's almost reaching the second cosmic speed, wait, this is already beyond the second cosmic speed."

I saw the second speed of this manned rocket in front of the camera in the live broadcast room, from the original first cosmic speed, to the second cosmic speed.

Because after the second-stage booster is ignited, it has a stronger impulse, after all, there is no first-stage booster below, and the mass of the entire manned rocket has changed lightly.

Now it has reached 12 kilometers per second at a very fast speed, and the whole world is in an uproar.

"How can there be such a fast speed, it is impossible, to reach the second cosmic speed at least the mass is very light, and the thrust is more violent.

But now that their second level has not yet been detached, they didn't expect to have the second cosmic velocity. ”

This kind of progress in science and technology has greatly shocked the whole world, and these space agencies in Europe and the United States.

The scientists inside were all dumbfounded, after all, they had never seen and dared to imagine that such a huge manned rocket had such a fierce propulsion.

Although the volume and mass of this manned rocket are smaller than the manned rocket launched by country M during the day.

But it's only relatively small, but such a rocket is still a behemoth.

But now that I'm heading toward space at the second cosmic speed, I feel like I'm about to break out of the Earth's gravitational sphere.

The gravitational pull of the Earth ranges from zero to 380,000 kilometers, which is equivalent to the distance from the Earth to the Moon.

"Now our manned spacecraft has left the atmosphere of 1,000 kilometers and is moving towards a high altitude at a very fast speed, and will soon reach the altitude of a far-orbiting satellite."

Most of the synchronous satellites are at an altitude of 30,000 kilometers, and now this manned spacecraft of the Dragon Kingdom has not detached itself from the second-stage booster after the medium altitude has passed.

So when some people saw this situation, their brows couldn't help frowning, but then they relaxed.

Because if the current satellite altitude can reach such a point, it has always proved that the propulsion is strong, and it has now left the grassroots level.

So how to recover this second-stage rocket booster, in fact, the difficulty has already been surpassed, and the difficulty of the third-stage booster from country M has already been surpassed.

You must know that most of the second and third stage rocket boosters of country M are detached from the orbits of medium-altitude satellites and then return to the earth.

However, this time, the second-stage rocket booster still did not detach from the orbit of the medium-altitude satellite, could it be that he would choose to disengage and return after going further, right?

It's incredible to think about.

"It's really amazing, they have completely left the big grassroots, so it's not so simple to recover the current secondary booster."

However, in the eyes of everyone, they saw that the second-level booster was separated, and like the previous first-level booster, it had the awareness of autonomous navigation.

After separation, it automatically ignites, then quickly turns back to the ground, and returns to the tarmac on the side of the tower.

The first-stage rocket booster on the Lingping apron has been taken away, and now the second-stage rocket booster has also landed smoothly after coming here, and in front of the TV, all the audience have given fierce applause for this.

"The second-stage rocket booster has also returned, so is it the turn of our third-stage rocket booster next?"

Many people are looking forward to the return of the three-stage rocket booster, but what shocks countless people is that until the rocket reaches an altitude of 35,000 kilometers, the three-stage rocket booster still does not detach.

That's when everyone was worried.

"It's strange, how come at this juncture, our three-stage rocket booster still hasn't returned."

"Yes, it stands to reason that the three-stage rocket booster should also be returned, but there is still no sign of separation, does it mean that we don't have a three-stage rocket booster?"

After such speculation came out, everyone immediately looked left and right at each other.

After such a guess came out, countless people at the scene looked at each other left and right, and at the same time, they were full of shock.

"That's right, it's very likely to be the case, doesn't that mean that our rocket boosters only need two stages, unlike those rocket boosters in other countries, which need three stages, and the three stages may not be able to reach a high high orbit."

In the previous launch of the satellite of country M, their scheduled orbit was not very high, at most it was only a medium-altitude orbit, after all, the main thing in this manned spaceflight is actually the technical research on rocket recovery.

In that case, the height of the rocket is not the most important thing, but the recovery of the booster, which is the most critical.

However, what no one expected was that it came from the Dragon Kingdom, although the rocket here seemed to be smaller, but they sent the entire rocket to a high orbit with the first and second level boosters.

And with such a huge volume, it is completely larger than an ordinary space capsule.

To put it bluntly, an ordinary space capsule is only a small part of the top of the rocket, and that part is inhabited by astronauts.

So space rockets often astronauts actually live in that very small capsule to operate.

Or doing experiments or whatever, all of this is done in a very narrow area.

However, this time, everyone also saw their own rockets with their own eyes, and they seemed to be staying in the space capsule.

But now that the whole rocket is gone, the three-stage booster and even the length of its capsule and the range of usable space seem to be more and more than those of other countries.

So in this case, many people's eyes are more focused on the space capsule.

At this moment, several astronauts in the capsule are still chatting with each other.

Although they are not given the voice, it is impossible to hear their conversation in the capsule at this moment.

But after seeing the smiles on their faces and the relaxed atmosphere, many people at home and abroad paid attention.

I was already shocked by all this, after all, the current altitude of the space capsule has reached an altitude of 35,000 kilometers.

In this case, it can be regarded as almost out of the gravitational range of the earth.

Because at this moment, the gravitational force at an altitude of 35,000 kilometers does not cause much heaviness.

When there is no sense of heaviness, it is equivalent to being in a weightless environment.
