Compared with their first unmanned experimental spacecraft, although this second spacecraft stayed in space for a week, it actually did not attract much attention.

The reason is still the lack of freshness, especially the rapid development of domestic aerospace technology in recent years, and their Walker manned spacecraft has been unveiled before, so naturally not so many people pay attention to it again.

This is just like the launch of a new aircraft carrier and the launch of a second aircraft carrier. The first one often attracts more attention. By the time we got 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 prepared to land at the Northwest Aerospace Landing Site.

The reason why we landed at the Northwest Space Launch Site instead of Siziwang Banner was mainly because of the different orbits and different missions. For this launch, they will prepare for the docking of Walker 3 with the space station, so it is natural to choose an orbit close to the space station.

In addition, Siziwang Banner is close to several densely populated cities and has gradually been turned into an alternate landing site in recent years. Therefore, according to relevant requirements, they can only choose the landing site here.

Wu Hao and the others were still watching the entire return process from the Aerospace Integrated Command and Control Center on the company campus.

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

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

Entering the 'black barrier' means that the return capsule will be interrupted from the information and data written in the ground remote control. Although the return capsule can be tracked through optical radar, no one knows how.

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

"The Northwest Aerospace Landing Site Measurement and Control Center reports that the infrared optical radar tracking is normal, the telemetry signal is normal, and the flight attitude of the return capsule is normal."

"Attention all units, we will begin to report that 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 the news that the No. 1, 2, and 3 crews began to maneuver toward the predicted landing site according to the predetermined plan."

"Car crew No. 1 received it!"

"Coach No. 2 received it!"

"Coach No. 3 received it!"

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

On the big screen, a search convoy consisting of off-road vehicles had already begun to move towards the predicted landing site. On the satellite map of the landing site, you can also clearly see the location coordinates of each search vehicle team, 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, you can also see the ground conditions of the entire landing field, including the progress of each convoy and so on.

"Attention 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 vehicle crew adjusted their route and headed for the new estimated landing site."

"The landing site measurement and control center reported that the infrared optical radar found the return capsule of the spacecraft. The return capsule is in complete shape and the flight attitude is normal."

Bang bang bang bang...

Upon hearing the 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've watched it, I can't help but be excited."

Haha, there will be more exciting scenes like this in the future. You have to prepare some life-saving pills in advance, so as not to get too excited when the time comes. Wu Hao joked with a smile.

In response, Zhang Jun smiled, waved his hands and said indifferently: "What are you afraid of? In the worst case, I will replace it with our intelligent bionic artificial heart, and then I will be a new and new human being."

Speaking of this, Zhang Jun clutched his chest and complained: "Ever since I got this disease, it has been really inconvenient and I can't do many things. Occasionally, like running, playing ball or something, I just do it. Rapid heartbeat.

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

Hello, you don’t take your life seriously. As for the heart, it's better to make it your own. If it doesn't work anymore, consider artificial ones.

With that 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 really comes time to replace it, let's replace it."

Zhang Jun shook his head, and then continued to look at the big screen, wondering what was going on in his mind.

"The landing site measurement and control center reported that the return capsule parachute group has been thrown out and deployed smoothly, and the parachute shape is normal."

Bang bang bang bang...

This time, the applause was even more enthusiastic. As long as the parachute opened, it meant that it was more than half successful. Everyone no longer had to worry, and the depressing atmosphere in the command and control center was also swept away.

"Attention all units, the following announcement will be made that 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 radar pod has discovered the return module!"

Following this report, the large screen also switched to the observation signal transmitted by the high-altitude drone. I saw a bright spot on the skyline, falling downwards.

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

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

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

The telemetry equipment on the convoy has all been aimed at the return capsule that is about to land a thousand meters above. Find Shuyuan www.zhaoshuyuan.com Now everyone is waiting and waiting for the return capsule to land.

As the return capsule gets closer to the ground, the surveillance cameras on site can clearly see the return capsule. The entire return capsule's surface has been burned and discolored, but its appearance is intact.

Boom!

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

The tail flame blew up the sand and dust on the ground, and soon the return capsule was covered by the dust and smoke. The three large parachute groups lost gravity and then slowly landed.

Blown by the northwest wind, the smoke and dust quickly dispersed and leaked out of the landed return capsule. The entire return capsule is in an upward position and has not tipped over.

The large parachute groups have also been automatically disconnected. The three large parachute groups began to float away in the distance under the northwest wind.
