――――――

When the future launch vehicle 1 reaches an altitude of about 100 kilometers above the earth's surface, it has completely shaken off the influence of gravity.

When the velocity of the first universe is reached, when the object obtains horizontal velocity in this direction, it does not need to increase the power to move around the earth.

However, the launch vehicle continues to move towards higher spaces, only the speed has ceased to increase.

In the ground command center, after the launch vehicle successfully escaped the gravitational pull of the earth, there was no cheering as expected.

Everyone remained quietly at their posts, looking at the launch vehicle that was moving away from the earth step by step.

At a distance of 1,000 kilometers from the Earth, the fairing at the head of the launch vehicle detached from the launch vehicle, and the capsule officially separated from the launch vehicle.

The two opposable engines ignited almost simultaneously, the launch vehicle quickly returned to Earth, and at the same time, under the acceleration of its own power, the capsule immediately came to the tenth point of the first satellite.

The first hatch of the future capsule opened, and a satellite of only about 100 kilograms separated from the capsule, and in the gravitational pull of the earth, away from the position of the capsule, then the two solar panels unfolded, and the satellite began to work.

At this time, the power system of the future capsule continues to increase its power and fly towards a height farther away from the ground.

on the ground. After watching the picture of the release of the satellite from the space capsule in the command center, Musk looked surprised.

Originally, he just thought that the three satellites carried by this launch would only be released in the first orbit or adjacent orbits at one time.

But I didn't expect it. It is actually a more difficult multi-orbit separate release of satellites, and such a technology is a new threshold for launch vehicle launch technology.

In particular, the design requirements for space capsules have become very demanding, and there are few countries in the world that can independently research and design such space capsules.

This was Musk's first surprise, and another surprise he felt was the launch vehicle that was returning to Earth. It actually came towards the location of the launch center.

This made him feel once again that Cai Ruichen was playing a little big.

Launch vehicle recovery technology is not a simple technology. The stakes are extremely high in their own right.

And in his opinion, it is the best choice for this rocket to fall on the sea, after all, on the sea, even if there is an accident. It will also not hurt personnel and facilities.

And such a technique is relatively simple. It is only necessary to reserve a certain amount of fuel on the launch vehicle, let the launch vehicle after the release of the capsule fall freely, and arrange the flatbed ship to meet the landing of the launch vehicle on the sea surface where the landing point has been calculated.

But the Future Technology Group obviously did not do this, because the launch vehicle in the process of returning has been resting its orbit, and the target is directly aimed at the launch vehicle recovery platform in the launch center.

In the process of returning to Earth, the launch vehicle is constantly resting its orbit. Musk's original thoughts of being a little proud were completely shattered in an instant.

In fact, the Dragon spacecraft of space exploration technology. It also has a similar ability, but it is not used to rest the rocket below the choice to land.

Instead, after the rocket has landed freely, in an uncontrollable situation, the landing point is calculated in advance, and then the ship is arranged to go to prepare in advance.

After re-entry, the engines on the Dragon spacecraft will start to run with the support of reserved fuel, reducing the speed at which the launch vehicle falls, and at the same time adjusting the landing attitude of the launch vehicle so that it slowly descends towards the position directly opposite the ship on the sea surface.

Compared with such technology, the future technology group also needs to prepare a large flatbed ship in the Arabian Sea that can recover the launch vehicle.

But obviously, this launch vehicle of the Future Technology Group looks more advanced, at least it does not need to land on a ship at sea that is not very stable, but relatively speaking, the technical difficulty is naturally higher.

Before the capsule could release its second satellite, the launch vehicle had already re-entered the atmosphere, returned to Iraqi airspace, and landed towards the northern desert location.

As the height of the launch vehicle fell rapidly, everyone in the command center couldn't help but hold their breath.

A successful rocket launch is not exciting enough for every crew and engineer involved, because it is only the first step to success.

However, the most critical rocket recovery is the most critical last step of this rocket test launch, and whether this launch can end perfectly depends on whether it can land stably on the recovery platform.

The launch vehicle, which was rapidly descending towards the satellite launch center, was less than 10,000 meters above the ground, and the engine in the tail nozzle sped up.

The speed of the launch vehicle is slowing down again, and by the time the launch vehicle reaches the recovery platform accurately, the speed has dropped to an extremely low level.

The flames of the tail vent will be sprayed on the ground, and there is no dust or dust around the prepared recovery platform, and almost everyone on the hard alloy platform has forgotten to breathe, watching the launch vehicle slowly descend like a helicopter.

All the balance wings on the launch vehicle, under the control of the computer, ensure that the launch vehicle and the ground are completely vertical at an angle of 90 degrees, and then get closer to the ground little by little, and finally it is like a helicopter, landing smoothly and vertically on the platform, and at the moment of stable landing, the engine of the launch vehicle also just stopped running.

When the launch vehicle landed steadily on the recovery platform, everyone in the entire command center cheered passionately.

Future Media Company also broadcast this historic picture to the world's audience for the first time, from the launch of the rocket to the successful recovery of the launch vehicle to the launch center, such an exciting picture is enough to make the whole of Iraq cheer.

This kind of picture also sees that many people are enthusiastic, of course, there are many people who think that this may not be anything, after all, there was a successful picture of rocket recycling and reuse a few years ago.

It's just that those who understand it are very clear that the future technology group's launch vehicle recovery this time is absolutely different in meaning, and it can even be said that such a recovery can be regarded as a real launch vehicle recovery technology.

Compared with the recovery method of American space exploration technology, it is more efficient and complete, and it seems to be the same, but in fact it is very different. (To be continued.) )
