Military Technology

Compared with their first unmanned experimental spacecraft, although this second spacecraft stayed in space for a week, it actually attracted less attention.

The reason is the lack of freshness, especially the rapid development of domestic aerospace technology in recent years, and their manned spacecraft Walker has been unveiled before, so naturally there is not so much attention once again.

This is like the launching of the new aircraft carrier and the launching of the second aircraft carrier. Often the first one attracts more attention. When it came to the second ship, it felt normal.

The Walker-2 unmanned experimental spacecraft soared in space for seven days. After completing a series of on-orbit experimental projects, it returned immediately and was ready to land on the Northwest Aerospace Landing Field.

The reason why I landed at the Northwest Space Launch Site instead of Siziwangqi is mainly because of the different orbits and the different missions. They will prepare for the docking of Walker-3 with the space station this time, so it is natural to choose an orbit close to the space station.

In addition, Siziwang Banner is close to several densely populated cities, which have gradually been converted into alternate landing sites in recent years. Therefore, in accordance with relevant requirements, they can only choose the landing field here.

During the whole return process, Wu Hao and the others still watched the whole process in the aerospace integrated command and control center of the company park.

Compared with the excitement the first time, everyone seemed calmer this time. Wu Hao and Zhang Jun sat on the VIP seats in the command and control hall, listening to various instructions and data information reports from the speakers.

"The return cabin begins to enter the'black barrier'."

Entering the ‘black barrier’ means that the return cabin will be interrupted with the information and data written in the ground remote control. Although the return capsule can be tracked by optical radar, no one knows exactly how it is.

So now everyone can only wait for the return capsule to break through the black barrier and re-establish a data information link with the ground.

"The Northwest Aerospace Landing Field Observation and Control Center reported that the infrared optical radar tracking is normal, the telemetry signal is normal, and the flight attitude of the return module is normal."

"Attention to all units, the first landing site is estimated to be 101 degrees XX minutes XX seconds east longitude and 4. degrees XX minutes XX seconds north latitude."

"The ground search team received that the first, second, and third vehicle group, according to the predetermined plan, began to maneuver to the predicted landing point."

"Car Group One received!"

"The second car group received!"

"Car Group 3 received!"

Through the monitoring system scattered everywhere, the rear command and control center can clearly see the real-time pictures of each scene through this set of equipment.

I saw that on the big screen, the search convoy composed of off-road vehicles had started to move towards the predicted landing point. On the satellite map of the landing site, it is also possible to clearly see the location coordinates of each search vehicle group, the direction of travel, and the estimated landing area fed back by the landing site measurement and control center.

Through the high-altitude drone hovering over the landing field, it is also possible to see the ground conditions of the entire landing field, including the progress of each fleet and so on.

"Attention to all units, the second landing site is estimated to be 101 degrees XX minutes XX seconds east longitude and 41 degrees XX minutes XX seconds north latitude."

"Each car group adjusts the route of travel and heads for the new estimated landing field."

"The Landing Field Measurement and Control Center reported that the infrared optical radar found that the spacecraft returned to the capsule, which had a complete shape and normal flight attitude."

Bang bang bang...

Hearing this news, there was a burst of warm applause in the hall.

Zhang Jun clapped his hands and said to Wu Hao, "Although this is the second time I have watched it, I still can't help but get excited."

Haha, there will be more excitement like this in the future. You have to prepare heart-saving pills in advance, so don't get too excited. Wu Hao joked with a smile.

In response to this, Zhang Jun smiled and waved his hand in an indifferent manner and said: "What's the big deal? I put on our smart bionic artificial heart, which was a new human at that time."

Speaking of this, Zhang Jun clutched his chest and complained: "Since I got this disease, it's really inconvenient. I can't do a lot of things. By chance, it's like running for a while, playing a ball or something. Fast heartbeat.

I sometimes think, if it doesn't work, I can just change it. "

Hello, I don't take my life seriously. The heart is still your own good thing, it's not good anymore, let's consider man-made ones.

As he said, Wu Hao sighed and said: "So, you have to take good care of it now, and don't let it continue to deteriorate. When it is really necessary to change, let's change it again."

Zhang Jun shook his head, and then continued to look at the big screen, wondering what else looked like in his mind.

"The Landing Field Measurement and Control Center reported that the parachute group of the return module has been thrown out, deployed smoothly, and the parachute shape is normal."

Bang bang bang...

This time, the applause was even more enthusiastic. As long as the parachute was opened, it was more than half of the success. Everyone didn't have to worry any more, and the depressive atmosphere in the command and control center was also swept away.

"Attention to all units, the third landing site is estimated to be 101 degrees XX minutes XX seconds east longitude and 40 degrees XX minutes XX seconds north latitude."

"The high-altitude drone reported that the synthetic aperture mirror radar pod has found the return pod!"

Following this report, the observation signal transmitted by the high-altitude drone was immediately switched on the big screen. I saw a bright spot above the sky, which was falling.

Soon, the optical observation equipment on the various search vehicle groups on the ground also found and tracked this bright spot, and saw the return capsule hanging under three huge parachutes.

"Attention to all units, the fourth landing site is estimated to be 101 degrees XX minutes XX seconds east longitude and 40 degrees XX minutes XX seconds north latitude."

As the forecast of the impact point becomes more and more accurate, several convoys have gradually approached the core area of ​​the landing field. However, they did not continue to enter, but stopped at the periphery to ensure safety.

The telemetry equipment on the convoy has all been aimed at the return capsule that is about to land from a kilometer above ~www.readwn.com~ Now everyone will wait and see, waiting for the return capsule to land.

As the return cabin gets closer and closer to the ground, the surveillance cameras on site can clearly see the return cabin. The exterior of the entire return cabin has been burnt and discolored, but the appearance is intact.

Boom!

At a height of tens of meters above the ground, the small solid engine on the return cabin ejected a huge tail flame and white smoke.

The tail flame blew up the sand and dust on the ground, and soon returned to the cabin to be covered by the dust and smoke. The three large parachute groups lost their gravity and landed slowly.

Blowing by the northwest wind, the smoke and dust quickly dispersed and leaked out of the return capsule that had landed. The posture of the entire return cabin is upward, and it does not tip over.

The large parachute group has also been automatically disconnected, and the three large parachute groups have begun to drift far away under the blowing of the northwest wind.
