Immediately afterwards, the second deceleration parachute was opened. This deceleration parachute was larger than the first one and could more effectively slow down the descent speed of the open return lander.
Under the action of the deceleration parachute, the speed of the open return lander dropped rapidly, but it was still very fast. As the second deceleration parachute was inflated by the high-speed airflow, it expanded.
Bang, the second parachute was cut off and abandoned.
Yu Chengwu and Zhou Xiangming watched the data changes on the screen nervously, their heartbeats synchronized with the trajectory of the open return lander.
At this time, the main parachute on the open return lander was also opened. This was a huge parachute, its area was several times larger than the previous deceleration parachute, and almost the entire open return landing was
The utensils are all shrouded below.
Under the action of the parachute, the speed of the open return lander further decreased and it began to descend slowly.
At this moment, the atmosphere in the entire Xinyuehu Space Command and Control Hall reached a climax. Everyone was staring closely at the screen, looking forward to the safe landing of the open return lander.
At this moment, at the Lenghu landing site located in the uninhabited land of the plateau, the ground search and rescue team and the aerial search team were already ready. They stared at the sky, their ears close to the radio, listening to every instruction from the command center.
When they saw that the signals detected on the equipment were becoming more and more obvious, the members of the ground search and rescue team excitedly clenched the equipment in their hands, filled with anticipation and nervousness.
The helicopter of the aerial search team flew towards the estimated coordinates of the landing site, and we rushed there at the slowest speed.
"Attention all units, the seventh landing point estimate has been reported above. The landing point of the open return lander is 102 degrees XX minutes XX seconds east longitude and 41 degrees XX minutes XX seconds north latitude; the landing point of the return capsule is 102 degrees XX minutes east longitude.
XX seconds, 41 degrees north latitude, XX minutes, XX seconds.”
Not all of the telemetry equipment under the convoy was aimed at the open return lander that was about to land a thousand meters below. The relevant footage was also simultaneously transmitted to the world through live broadcast, attracting the attention of countless people.
As the frame containing the gold meteorite star core gets closer and closer to the ground, at a low altitude of about two or eight meters from the ground, with a bang, the air bag at the bottom of the frame rapidly expands, like a car steering wheel
Same as the dangerous airbags outside.
Through the monitoring systems scattered everywhere, the forward command and control center can vaguely see the real-time pictures of each scene through that set of equipment.
"Rehu Landing Site Measurement and Control Center reports that the Hongli optical radar tracking is abnormal, the telemetry signal is abnormal, the open return lander is broken, the parachute is abnormally inflated, and the flight attitude is abnormal. The return capsule is broken, the parachute is abnormally inflated, and the flight
Abnormal posture."
As for the main parachute system under the frame, it was automatically cut off before the frame lost tension during landing, and was blown nearby by the wind.
On the small screen, I saw that the search convoy composed of off-road vehicles had not yet finished setting off and was maneuvering towards the predicted landing site. Under the satellite map of the landing site, the location coordinates of each search vehicle group could also be seen vaguely.
Retreat direction, and the estimated landing area fed back by the landing site measurement and control center.
Bad! Zhang Jun clapped his hands and pulled Wu Hao and said excitedly: "Haozi, success is getting closer and closer to you."
"Car crew No. 7 received it!"
"Car crew No. 1 received it!"
"Attention all units, the eighth landing point estimate has been reported above. The landing point of the open return lander is 101 degrees XX minutes XX seconds east longitude and 40 degrees XX minutes XX seconds north latitude; the landing point of the return capsule is 101 degrees XX minutes east longitude.
XX seconds, 41 degrees north latitude, XX minutes, XX seconds.”
I hope so. Wu Hao nodded, with a smile on his face.
"Rehu Landing Site Measurement and Control Center reported that Hongli Lidar found the open return lander, the lander was broken, the parachute was full, and the flight attitude was abnormal.
"The ground search team received the message that the No. 178 crew, according to the predetermined plan, maneuvered towards the predicted landing site."
As the landing point forecast became more and more accurate, several convoys had not yet gradually approached the core area of the landing site. However, we did not continue to retreat, but stopped in the inner circle to ensure danger.
By circling the low-altitude manned aircraft under the landing site, one can also see the ground conditions of the entire landing site, including the retreat of each convoy, etc.
The orange airbag quickly expanded and filled up. As the frame hit the ground, the entire airbag was squeezed and deformed by the huge force, and finally deflated and collapsed.
Low-altitude manned aircraft No. 7 reported that the airborne synthetic aperture radar pod had not yet captured the return capsule, the main parachute was full, the flight attitude was abnormal, and the landing speed was abnormal.
Very slowly, the optical observation equipment under the search vehicles on the ground also discovered and tracked the bright spot, and saw the square frame hanging on the small parachute. Fixed in the middle of the frame was the gold that everyone was paying attention to.
Meteorite core.
Bang bang bang...
At this time, the entire frame, including the inner metal film wrapping the gold meteorite star core and the remaining unburned foam insulation material, has not been burned and discolored by the low-speed airflow, but the inner shape is still broken, which is important.
Upon hearing the news, there was a burst of cold applause outside the small hall.
"Attention all units, the above report has concluded the first landing point estimate. The landing point of the open return lander is 102 degrees XX minutes XX seconds east longitude and 41 degrees XX minutes XX seconds north latitude; the landing point of the return capsule is 102 degrees XX minutes east longitude.
XX seconds, 41 degrees north latitude, XX minutes, XX seconds.”
Haha, the main parachute hasn't opened yet, so it's not 44% successful yet. Zhang Jun said with a smile.
"Coach No. 8 received it!"
"Each vehicle crew adjusted their retreat route and retreated to the new estimated landing site."
"Low-altitude manned aircraft reported that the synthetic aperture radar pod has not found the open return lander!"
As for the entire frame, because the landing site is located under a relatively steep sand dune, the frame falls upwards along the sand dune.
"Attention all units, the seventh landing point estimate has been reported above. The landing point of the open return lander is 101 degrees XX minutes XX seconds east longitude and 40 degrees XX minutes XX seconds north latitude; the landing point of the return capsule is 101 degrees XX minutes east longitude.
XX seconds, 41 degrees north latitude, XX minutes, XX seconds.”
As the open-return lander got closer and closer to the ground, no one could vaguely see the open-return lander under the low-definition camera under the Sentinel system arranged under the Rehu landing site.
"bad!"
Bang bang bang bang...
Following that report, the small screen also switched to the observation signal transmitted back by a low-altitude manned aircraft. Under the sky, there was no bright spot, and it was falling upwards.
"The Rehu Landing Site Measurement and Control Center reported that the Hongli Lidar detected the return capsule. The capsule was broken, the parachute was full, and the flight attitude was abnormal.
It hasn’t started yet, everything is still bad now. Wu Hao shook his head. Although I really wanted to dampen Zhang Jun’s interest, I still couldn’t help but say.
