Chapter 39 Chapter Eleven

On the morning of October 28, Yang Fan found Xu Zhenyu with a telegram: "The operator asked me to hand it over to you." Xu Zhenyu took the telegram and looked at it, and it was the reply he was looking forward to: Xu Zhenyu was very happy, and took the telegram to find Liang Weizhou and Ren Sihong. In the evening, the satellite communication room on the ship sent Xu Zhenyu four false-color remote sensing photos, and he immediately took them to the detection cabin.Scientists also rushed to hear the news.Zhang Kai looked at these photos as if he had found a treasure.You know, they are not easy to come by!

Still in the daytime today, my country's marine resources satellite flew over the Xisha Islands, and recorded the details of this sea area with a multispectral scanner (MSS) in a satellite orbit 910 kilometers above the ground. The marine resource satellite ground data receiving station in Hainan records the voltage data transmitted from the satellite on the video tape exactly.Then it was converted into an accurate image and recorded on a black and white transparent film with four bands.Then, it is transferred into a set of false color remote sensing photos. The Hainan ground station forwarded it to the "Zheng He" through a communication satellite located above the equator at 70 degrees east longitude and 35,810 kilometers above the ground.

Zhang Kai looked at the photos carefully.They are all refined, and each one reflects a sea area of ​​3,000 square kilometers.He thought in his mind that what needs to be searched is only a 1,000-square-kilometer sea area between Beijiao and Zhaoshu Island, which only accounts for one-third of the photo.Therefore, he was very impressed by the exploration capabilities of the resource satellite. Zhang Kai selected a false-color photo in the MSS7 band, and he pointed out a red dot hidden in a dark green for everyone to see: "There is a relatively high temperature spot here, so it's in this sea area." Xu Zhenyu asked Zhang Yu:

"What band does MSS7 work on?" "Near infrared." "How many degrees is this dark dot higher than the surrounding sea?" "0.2° higher" "Where are the geographic coordinates?" Yue Jing took the photo and put it into an interpreter. "East longitude 112°16', north latitude 17°06'." Yue Jing said. "Can you see what's going on under the sea?" Xu Zhenyu asked again.Zhang Kai said regretfully: "On the blue-green light band MSS4, it can be seen hundreds of meters deep. Unfortunately, there is no sign of a spacecraft in this picture."

Liang Weizhou felt that this local high temperature point in this sea area was very strange, although it was only 0.2 ℃ higher than the surrounding sea area.He even wondered, does this mean that the power plant in the wreckage of the spacecraft is still emitting heat?Xu Zhenyu agreed with him and advocated that the sea area near the high temperature point should be investigated first to see if it has any connection with the wreckage of the spacecraft. The "Zheng He" continued to move forward relying on the radar to determine its azimuth, and arrived at 112°16' east longitude and 17°06' north latitude in a short time.Zhang Jie's assistant turned on the sonar device in the detection cabin.He and Liang Weizhou and Xu Zhenyu will take turns on duty here to monitor and check the working conditions of the sonar devices at any time to see if the ultrasonic signals provided by Fang Yutian are generated here.

That night, they discovered that one of the sonar receivers on the side of the ship had been broken loose by the waves.Xu Zhenyu turned on the searchlight at the bow, climbed down from the gangway, and fastened the receiver.When he came up, Liang Weizhou saw something like a black cauldron flashing in the sea.He greeted: "Do you see what that is?" Xu Zhenyu looked down, the water was very clear, and under the searchlight, he could see a depth of about ten meters, but there was nothing there.It took him a while to realize that it was a squid scurrying around under the light.There are two big jellyfish dancing in the water a little farther away, with a very graceful posture.Neither Huang Jingzhi nor Ren Sihong had ever seen squid and jellyfish, and they all came to watch after hearing the news.

They didn't receive the ultrasonic signal under the sea for several days, and they even wondered if Fang Yutian made a mistake that time?Fang Yutian said very frankly; "That's right, definitely right!" On the night of November 1st, Xu Zhenyu finally found the ultrasonic signal on the recording paper of the sonar device.He also determined that the source of the signal was just south-west of where the ship stopped.He took out the original fax and telegram to check with it, and the result was exactly the same.Fang Yutian also brought the original record paper, which was completely consistent after checking.This not only affirmed that the situation provided by Fang Yutian was correct, but also provided new evidence for the speculation that there were spaceships under the sea.

A new exploration operation is about to begin. The "Zheng He" returned to the Xinghua Island base in the early morning of the second day, and the chief purser brought several loads of fresh vegetables and several baskets of grouper on the island.We also disembarked and had a good rest on the island for a day. On November 3, the "Zheng He" cruised back and forth from the point where the water temperature was higher, and at the same time used the argon ion laser underwater television system to directly detect the seabed in this area. Outside the porthole, the waves are undulating and the sea wind is whistling.But in the detection cabin, people work as usual.They searched for several days in a row, but still could not detect the specific location of the sunken ship.

On November 8, as usual, the scientific workers on board gathered in the detection cabin early in the morning.They watched intently the flat-screen TV on the bulkhead. The seabed in the TV was calm, yet very strange. Suddenly, a large squid broke into the camera.Maybe it was the laser TV camera that startled it, the squid let out a thick jet of ink that blackened the water, and the TV screen was covered in a black mist.After a while, the water became clear again.At this moment, everyone saw almost at the same time that there was an object embedded in the thick sediment on the seabed, and the exposed part looked like a ball.There are many unnamed shellfish attached to it, and there is a layer of soft sediment on the top.There are many small holes in the sediment, which seem to be drilled by some small insects.Although there are many exposed places on the hemisphere, it is difficult to tell what it is.

At this time, Zhang Wei came over and told Xu Zhenyu that the magnetic detector had found out that the hemisphere was a magnetic metal object.He also said that the water depth measured by the water depth sounder was 912 meters.After checking the charts, there is no special record on this position. Xu Zhenyu made a phone call to Captain Li, and Captain Li immediately ordered the ship to berth on the spot.A working boat was hoisted down from the "Zheng He", carrying several sailors and several members of the marine exploration team and sailed to a distance to carry out artificial explosion operations.After a while, a huge jet of water erupted from the sea surface on the working boat, and then there was a loud explosion under the water.Zhang Kai recorded the artificial explosion sound waves reflected from the seabed in time through the sonar system.After a comprehensive analysis, a preliminary conclusion was drawn that the sunken object was a hollow spherical body with damage on the surface.It has been half-buried by the soft sediment of the ocean floor.It is about twenty meters in diameter.

Captain Li called and told Xu Zhenyu: "The current coordinates are: 112°15' east longitude, 17°03' north latitude." Xu Zhenyu took the chart and drew a red circle on that coordinate.This location is south of the high temperature point on the sea surface, about 3 nautical miles apart.Yue Jing looked at it and found it very strange: "Why is it inconsistent with that high temperature point?" "There is a sea current from south to north here." Fang Yutian said. It seems that this is the wreckage of the four-person spaceship of Tianyuan! The workers and crew members on board were very excited. They shook hands and congratulated each other, talking enthusiastically.
