Chapter 576 Radio Telescope
Lin Fan was awakened by the ringing of the bell. Without any time to think, he jumped up from the sofa and rushed out.
Run to the information room in one breath, the screen was calm, and none of the random speculations in her mind came true.
"What's going on?" Lin Fan held on to the back of Zhu Cunjun's chair and took a few breaths. When he looked up, it was only past one in the morning.
Wu Yusen handed her a bottle of water from the side, "It's not clear yet. We just caught an abnormal signal. The general control thinks it may not be good, so you should be alert."
Lin Fan was not thirsty, but Wu Yusen handed it to her, so she took it, opened it and took a few sips.
"Abnormal signal? The satellites have all fallen, can they still be captured?"
She looked up at the big screen, and many pictures showed that the logistics were cleaning up the mess on the ground.
The sparse remains were all hit by artillery, and the glory before them could no longer be seen. The more complete ones were basically thrown down by her own hands.
On the other hand, in the Western Hemisphere, there are not many wreckage on the ground, only scattered ones.
"Old P and the others move very fast." Lin Fan muttered, "What are you excited about this time? Are you so active in working?"
These foreigners are probably used to having an 8-hour weekend. At this special moment, they didn't look very nervous.
She had been cleaning up the remains of the big spider for a long time. When she went to destroy the launcher, she accidentally saw the spider corpse still there on the split screen in Hua Province.
Why are your hands and feet so fast this time? It's a scam!
Lin Fan rolled his eyes and was about to ask John Woo, but he was vague.
"Although the satellites are gone, isn't the World Tree network still there? There are also some receiving devices on the ground, such as giant radio telescopes. But it is not an optical telescope, and the visual effect is not as good as the telescope in space."
Everyone unanimously decided not to let Lin Fan know about the energy cannon, especially on the eve of the upcoming battle, for fear of affecting her condition.
Lin Fan remembered the photo model he had seen at the observatory before and responded repeatedly.
"Oh, I remember, the boss has a pot. I also said, there are so many satellites in the sky, are these big things useful? Unexpectedly, it didn't take long before they were actually used. On.”
So, there are some things that you really shouldn’t think too much about, this is not...
...Should she really check out crow brains?
"However, I remember that those pots don't seem to have cameras, right? Are they really telescopes?" Lin Fan asked in a timely manner, pulling out the important openings among a bunch of messy thoughts.
“It’s just a metaphor to say it’s a telescope. Radio telescopes are actually signal receiving devices.”
“They were first put into use during the Z War, in order to monitor enemy missile movements. , use it by sending out an alarm in time."
"It sounds very powerful, but how can such a slippery pot detect something so invisible as its trajectory?" Puzzled.
"Simply put, its pot surface is an antenna, which uses radio waves to confirm the position and trajectory of flying objects."
"Oh." Lin Fan nodded silently and listened briefly. .
She originally wanted to ask where the radio waves came from and how they were received.
Let’s forget it after thinking about it. It sounds like a very complicated issue, so don’t delve into it further.
“These radio telescopes can receive weak electromagnetic waves emitted by various materials and celestial bodies, and are used to locate and identify celestial objects. The larger the area of the pot, the farther away it can be detected.”
< br>
"I can't remember the specific data. Anyway, it seems that the big pot of our G family is said to be able to detect the distance outside the Milky Way. It is said."
"Is it so powerful?" Lin Fan was surprised. .
She still remembers what Zhu Cunjun told her about the Kuiper Belt. It took country P’s telescope 10 years to fly there, and it was just the edge of the solar system.
Can we transcend with just one pot?
"It is very powerful! However, this technology seems to be more susceptible to interference from some radio data such as FM radio stations, TVs, mobile phones, etc. So most of them are built in deep mountains." "It seems that in recent years, we have joined forces Some G families also built a radio array, with hundreds of cauldrons lined up side by side, hoping to continue exploring the mysteries of deep space. It is not known whether it was destroyed by this attack."
“I didn’t see the array in the area I was involved in.” Lin Fan recalled, “Maybe he escaped.”
Wu Yusen shook his head, “I don’t know, this matter People from the space agency know best. You have to ask them. Aren’t all the space telescopes gone now? The people from the space agency have transferred radio telescopes to use them, so they can’t focus on the Milky Way. Let’s just look at the front.”
"Then what has been detected now?" Lin Fan looked at the big screen without real-time images and was really not used to it.
“There are five flying objects parked near the low-Earth orbit outside Lanxing, and they are larger than the previous advance ships...”
Lin Fan looked at John Woo nervously when he heard this.
The advance ship is already very difficult to deal with. Both the ship itself and the monsters inside are worrying.
Now there are even larger spaceships, five of them.
Lin Fan couldn't explain what she felt in her heart. Her instinct was to reject it.
“It was these things that caused satellites to fall down before.” John Woo was also very unhappy and said bitterly, “Originally, they had been hanging on the periphery of low-Earth orbit, but now the radio telescope has detected that they are moving.”
"Moved?" Lin Fan's scalp was numb, "Five together?"
"Yes, five together, approaching Lanxing." John Woo looked helpless, "I don't know what bad move they are holding back. , but it’s definitely not a good thing.”
“Their speed is not very fast now, a bit similar to the cruising speed of a space shuttle, but who knows what will happen next? That’s why they picked you up. "
When it comes to emergency response speed, only Xingchen and Apollo on Lanxing are the first to bear the brunt.
Over in country P, Apollo is also on standby.
Lin Fan scratched his forehead and asked a little irritably, "How was the last wave of losses? Was it big?"
"It was okay. You two plug-ins took action, and later ground firepower also provided support. Basically, Within the controllable range." Wu Yusen saw that Lin Fan was a little irritable and reassured, "There are no casualties and a small amount of damage to the infrastructure. It is much better than we imagined."
If there were not two mechas rushing in. In front, if there is no global firepower behind them, just satellites falling from the sky can hit them hard.
It is not just buildings that are destroyed, but also people’s hearts.
Although the current situation is not very good, at least they have held on and did not lose.
Coupled with the previous wave of concentrated fire, many people let out a bad breath. The revenge against Gro became more intense.
In terms of momentum, it is a good thing.
It's past midnight now. The time until the barrier opens has been shortened again.
As long as they persist, once the barrier between the ugly women is opened, their safety will be guaranteed.
Six days.
Six days to go!
I feel dizzy every time I look up information. I look for a long time and extract one or two useful sentences.
A radio telescope is that cauldron with a diameter of 500 meters, as you know.
In fact, there are fixed ones, some that can shake your head, and some that are not round. The text does not go into details.
Regarding the detection distance of the cauldron, I found that it is 7 billion light years. That far away? I am also a little skeptical, but... this is a novel after all. If there are any errors in this aspect, just treat it as necessary for the novel, hahahaha, mainly because I am lazy. I don’t want to check anymore.
