Mindy Parker poured a cup of coffee and returned to her desk.
At this time, a communication message lit up on the computer screen.
The message was from Vincent Kapoor.
Vincent Kapoor is NASA's Mars mission director.
Mindy Parker clicked on it and saw that she was asked to check the coordinates of a certain location on Mars.
Seeing this, she opened the system without hesitation and entered the latitude and longitude sent by Vincent.
At this glance, I noticed something was wrong.
She kept enlarging the satellite pictures and comparing them with the satellite pictures from a month ago. Her face changed drastically, she picked up the phone and called the security guard, asking for Vincent's emergency contact number.
2:30 in the morning.
NASA Director Sandy Sanders, Mars Mission Director Vincent and NASA Media Relations Director Anne Montrose gathered in the Satellite Communications Department and looked at the Mars satellite pictures on the big screen.<
/p>
Compared with the satellite images from thirty days ago, there are several more things in the current images:
"The solar panels have been cleaned. Rover 2 was originally in a charging state, but now its position has been moved and there is an extra machine!" Vincent said.
"What the devil!" murmured Anne Montrose.
"What do you think that machine is?" Sandy Sanders asked solemnly.
"I don't know..." Vincent shook his head and said, "If it is not an industrial product made by Martians, then there is only...oh...Pathfinder! Mark! It must be Mark! Mark is not dead! He took the Pathfinder
The Router has been dug up! He wants to contact us!"
Vincent suddenly remembered this incident, he smiled bitterly and said, "It seems I have to catch a flight!"
"Where?" Anne Montrose, director of media relations, asked in confusion.
"California, Jet Propulsion Laboratory." Sandy Sanders looked at the satellite picture without blinking and said.
"Yes." Vincent's eyes never left the satellite picture.
The next morning.
Vincent came to the Jet Propulsion Laboratory in California.
The director of the laboratory was a Chinese named Bruce Wu. He received Vincent, and they came to the warehouse at the corner of the laboratory.
There is a machine here - a replica of the 1997 Mars rover - [Pathfinder].
"Okay, let's take action." Vincent glanced at the machine with emotion and said to Bruce Wu and other engineers in the laboratory.
They skillfully started the machine and connected the system.
Not long after it was completed, the old desktop computer showed that it had received remote sensing signals.
Vincent's face suddenly burst into a smile of joy.
He couldn't help but clap his hands.
Several other engineers also felt indescribably excited as they operated the system.
An engineer said, "Camera."
As soon as he finished speaking, the camera on the replica of [Pathfinder] started to move.
"Okay, let's take a panoramic photo." said the engineer in front of the computer.
The camera moved again.
Vincent looked back at the engineer in front of the computer, "Have you received the signal? Have the photos been sent?"
"I was thinking that it would be better for us to see a vibrant red planet than to see a pure black screen."
"What's wrong?" Vincent was puzzled.
"Tim is our best communications expert, and we appreciate his meanness." Bruce Wu explained to Vincent in a humorous tone, then turned to Tim and said viciously, "I will kill you!
”
He was warning Tim not to act weird.
Tim shrugged and said that there was nothing he could do. The computer screen showed pure black, but soon, a black and white photo was passed over.
Above the photo are three card boards inserted into the ground.
The two cards on the left and right say "yse" and "no"!
The card in the middle said: "You can see it, right? It's too troublesome to communicate like this. We are trying to update the rover's system and connect it to the Pathfinder's broadcast so that we can communicate better.
!"
This is really great advice!
Because according to the current situation, only one-way communication can be made through [Pathfinder], and the transmission of information is extremely difficult.
Slightly more complex information transmission will be very time-consuming and energy-consuming.
The suggestion given by Wu Siyuan allows both parties to communicate in text and transfer complex information to each other. Of course, because of the distance between the ground and the fire, a minimum waiting time of 22 minutes for communication is essential! p>
"Mark is a genius!" Vincent couldn't help but said after seeing this sentence.
The eyes of others also lit up.
As everyone knows, this method was originally thought up by them, but Wu Siyuan plagiarized it in advance.
In short, after two days of complicated communication, Wu Siyuan finally got the underlying code given by the other party and successfully modified Rover 2. The two parties were finally able to communicate via text with a delay of 22 minutes.
NASA has long publicized this event and decided to broadcast the first exchange live around the world.
This is also a characteristic of the United States. Funerals are held with joy!
In other words, expectation management.
For example, if you want to announce an important data, you are worried about the impact on the market, so you pretend to spread an exaggerated data, and then the stock market immediately panics. At this time, the US National Security Agency comes out to refute the rumor and announces a smaller number.
.
When the market looked at it, it thought it was a good thing, so the stock market rose again instead of plummeting. This is expectation management!
The United States is very skilled at playing this game.
It was clearly their fault for leaving Mark on Mars.
However, through packaging, they make others feel that they are doing something great and meaningful.
………………………………………………………………………………………………………………………………
…
Under the spotlight, Vincent typed his first sentence, "I am Vincent Kapoor. We have been watching you since the 54th day of Mars. The whole world is applauding your safe return.
You did a great job finding the Pathfinder. We are working on a rescue plan. At the same time, we are preparing a supply mission to give you enough supplies to last until Ares 4 arrives."
After the message is sent.
22 minutes later, Wu Siyuan received the message in the rover on Mars.
As soon as he thought about it, he sent a message, "All over the world? Vincent, you won't tell me that it is a global live broadcast now, right?"
Forty-five minutes later.
Wu Siyuan saw the message on the screen, "Yes, we are doing a global live broadcast, and the whole world is watching you! Behind you are all of us!"
The corners of Wu Siyuan's mouth raised slightly, that's really great.
