If you want to understand the differences in the advantages and disadvantages of electric propulsion and chemical propulsion, you must first understand a concept that all junior high school students understand, and that is acceleration.
"A bad news..."
Especially the rescue plan that was launched within 15 minutes immediately made the staff of the NASA Ares Project Ground Command Center blush.
On a shorter distance scale, due to the huge thrust of chemical propulsion, the spacecraft can reach a very high speed in a short period of time, so it is more advantageous in terms of flight time overall.
In this dilemma, the White House finally made a choice. At the same time, the Chinese Ministry of Foreign Affairs received a call from the President of the United States, and during the call, the President of the United States formally made a request for rescue.
In a deep and dark space, the Xiaguang spacecraft, which had delivered the Yuegong station astronauts to their destination and completed the supply of working fluids, was slowly separating from the Yuegong space station.

The assistant smiled bitterly.

Although electric propulsion cannot erupt the working medium in a short period of time in exchange for huge thrust like chemical propulsion, it can achieve a speed far greater than that of chemical rockets through continuous acceleration and huge specific impulse. maximum value.

[I feel ashamed of NASA.]
However, if the distance scale is enlarged to millions of kilometers or even tens of millions of kilometers, it is another situation.
"Because of those Americans?"
"The name seems to be... The Martian."
They spent three days analyzing various options and possible consequences, but no one responsible could tell them whether to save it or not, so they missed the best window for launch.
However, less than five minutes after the announcement was issued, NASA received a bill sent from across the Pacific Ocean.
Although electric propulsion cannot erupt the working medium in a short period of time in exchange for huge thrust like chemical propulsion, it can achieve a speed far greater than that of chemical rockets through continuous acceleration and huge specific impulse. maximum value.
At this moment, his assistant walked over from the side.
[Don’t tell me about the difficulty of rescue. Now I seriously doubt that NASA has no intention of saving people at all!]
"This is the Xiaguang. We have completed all flight missions and are requesting instructions for the next step."
In this dilemma, the White House finally made a choice. At the same time, the Chinese Ministry of Foreign Affairs received a call from the President of the United States, and during the call, the President of the United States formally made a request for rescue.
Silence lasted in the cockpit for a short while.
15 minutes ago.
A faint blue arc of light ejected from the Xiaguang's five electric propulsion engines, dragging the silver spacecraft toward the distant and boundless sea of stars...
From receiving the rescue request to the departure of the rescue team, it took less than 15 minutes.
Therefore, it will take 3 months for a BFR rocket to travel to Mars across a distance of tens of millions of kilometers.
Although electric propulsion cannot erupt the working medium in a short period of time in exchange for huge thrust like chemical propulsion, it can achieve a speed far greater than that of chemical rockets through continuous acceleration and huge specific impulse. maximum value.
How come you even invited reporters!
But for Xiaguang, which sets off directly from the lunar orbit, one month is enough.
"gentlemen… "
Liu Biao reminded: "Signal from the ground command center."
"Yes."
How come you even invited reporters!
"What's wrong?"
"A bad news..."
"Because of those Americans?"
"A bad news..."
This is even after missing the optimal launch window for the Hohmann transfer orbit. If the relative position of Mars and the Earth happens to be at the optimal launch position, it may not even take a month to complete a mission from the moon to Mars. flight.
I didn't have time to say hello and watched them fly away.
They spent three days analyzing various options and possible consequences, but no one responsible could tell them whether to save it or not, so they missed the best window for launch.
At almost the same time, the Xiaguang spacecraft, which was performing a mission in lunar orbit, received the news and immediately launched a preparatory plan. After the Yuegong space station completed the supply of working fluids and living supplies, it followed the route calculated in advance by the ground command center. Channel to Mars.
In this dilemma, the White House finally made a choice. At the same time, the Chinese Ministry of Foreign Affairs received a call from the President of the United States, and during the call, the President of the United States formally made a request for rescue.
Originally, the White House planned to deal with the situation in a low-key manner, but unexpectedly, the Chinese side started to handle it with great fanfare, holding press conferences and reporting the rescue progress to all walks of life in real time.
[Don’t tell me about the difficulty of rescue. Now I seriously doubt that NASA has no intention of saving people at all!]
In a deep and dark space, the Xiaguang spacecraft, which had delivered the Yuegong station astronauts to their destination and completed the supply of working fluids, was slowly separating from the Yuegong space station.
After seeing this bill, Director Carson was almost furious.
Ten minutes ago, the news reached the Jinling Space Launch Center, and the staff who finished the navigation work immediately returned to work.
Sitting in the cockpit, Xu Zhenghong reached out and pressed his helmet, and reported to the ground command center in a clear voice.
"This is the ground command center. Congratulations on completing all tasks. Now please switch to cruise mode and wait for the next instruction."
"The name seems to be... The Martian."
"This is the Xiaguang. We have completed all flight missions and are requesting instructions for the next step."
Carson: “…”
Is this treating him as a cash machine
[The rescue team was dispatched within 15 minutes... God, how is this possible!]
"What's wrong?"

Just when Xu Zhenghong half closed his eyes and was about to sleep for a while, the signal light in the cockpit suddenly flickered slightly.
Originally, the White House planned to deal with the situation in a low-key manner, but unexpectedly, the Chinese side started to handle it with great fanfare, holding press conferences and reporting the rescue progress to all walks of life in real time.
"Received, switching to cruise mode."
He opened his mouth and asked in a forced voice.
What about doing things in a low-key manner as promised
A total of $1.7 billion.
Speaking of this matter, Liu Biao couldn't help but feel emotional.
Not only that, China's open, transparent, serious and responsible attitude towards "humanitarian" rescue was in sharp contrast to NASA's previous push and pull, and for a time, all the work of the Ares program ground command center was paralyzed. The personnel, as well as those who supported the Ares project, felt ashamed, and the direction of public opinion changed overnight.
Therefore, it will take 3 months for a BFR rocket to travel to Mars across a distance of tens of millions of kilometers.
"5, 4, 3, 2, 1... fire up!"
Liu Biao reminded: "Signal from the ground command center."
Sitting in the passenger seat and looking at Xu Zhenghong who had switched to cruise mode, Liu Biao asked casually.

How come you even invited reporters!
In order to save face and show its determination to bring its own citizens home, after realizing the seriousness of the matter, the White House urgently announced that it would bear the entire budget of the rescue plan.
But even so, this efficiency is enough to make them far behind.
As a result, the Chinese side did not conduct any budget assessment. In less than 15 minutes, they determined the channel and dispatched a rescue team, which efficiently destroyed more than one street.
Silence lasted in the cockpit for a short while.
However, less than five minutes after the announcement was issued, NASA received a bill sent from across the Pacific Ocean.
This is even after missing the optimal launch window for the Hohmann transfer orbit. If the relative position of Mars and the Earth happens to be at the optimal launch position, it may not even take a month to complete a mission from the moon to Mars. flight.
Liu Biao reminded: "Signal from the ground command center."
Especially the rescue plan that was launched within 15 minutes immediately made the staff of the NASA Ares Project Ground Command Center blush.
At almost the same time, the Xiaguang spacecraft, which was performing a mission in lunar orbit, received the news and immediately launched a preparatory plan. After the Yuegong space station completed the supply of working fluids and living supplies, it followed the route calculated in advance by the ground command center. Channel to Mars.
Looking at the subordinates of his mother-in-law and mother-in-law, Carson said impatiently: "Stop talking nonsense and speak quickly."
Although electric propulsion cannot erupt the working medium in a short period of time in exchange for huge thrust like chemical propulsion, it can achieve a speed far greater than that of chemical rockets through continuous acceleration and huge specific impulse. maximum value.
"Received, switching to cruise mode."
A total of $1.7 billion.
"A bad news..."
Looking at Director Carson with a sullen expression, the assistant hesitated for a moment and hesitated to speak.
The assistant smiled bitterly.
I didn't expect that we would meet again soon, but in this form.
On a shorter distance scale, due to the huge thrust of chemical propulsion, the spacecraft can reach a very high speed in a short period of time, so it is more advantageous in terms of flight time overall.
Scan code and pay in installments are supported.
Looking at the subordinates of his mother-in-law and mother-in-law, Carson said impatiently: "Stop talking nonsense and speak quickly."
Sitting in the cockpit, Xu Zhenghong reached out and pressed his helmet, and reported to the ground command center in a clear voice.
They spent three days analyzing various options and possible consequences, but no one responsible could tell them whether to save it or not, so they missed the best window for launch.
After seeing this bill, Director Carson was almost furious.
What about doing things in a low-key manner as promised
Especially the rescue plan that was launched within 15 minutes immediately made the staff of the NASA Ares Project Ground Command Center blush.
Scan code and pay in installments are supported.
In this dilemma, the White House finally made a choice. At the same time, the Chinese Ministry of Foreign Affairs received a call from the President of the United States, and during the call, the President of the United States formally made a request for rescue.
Looking at Director Carson with a sullen expression, the assistant hesitated for a moment and hesitated to speak.
…
Although they also knew that this rescue plan was definitely not made within 15 minutes. It might have been prepared before the video call, or even three days ago.
$1.7 billion!
In order to save face and show its determination to bring its own citizens home, after realizing the seriousness of the matter, the White House urgently announced that it would bear the entire budget of the rescue plan.
Originally, the White House planned to deal with the situation in a low-key manner, but unexpectedly, the Chinese side started to handle it with great fanfare, holding press conferences and reporting the rescue progress to all walks of life in real time.
"Received, switching to cruise mode."
Liu Biao reminded: "Signal from the ground command center."
Damn it, you can build a new Xiaguang!
Carson: “…”
Looking at Director Carson with a sullen expression, the assistant hesitated for a moment and hesitated to speak.
Sitting in the passenger seat and looking at Xu Zhenghong who had switched to cruise mode, Liu Biao asked casually.
"What documentary?"
"Yes!" Seeing the impatient expression of his boss, the assistant nodded quickly and said, "... Just half an hour ago, we found on the official website of the Chinese official media that they also released a documentary program. "
Is this treating him as a cash machine
Originally, the White House planned to deal with the situation in a low-key manner, but unexpectedly, the Chinese side started to handle it with great fanfare, holding press conferences and reporting the rescue progress to all walks of life in real time.
They spent three days analyzing various options and possible consequences, but no one responsible could tell them whether to save it or not, so they missed the best window for launch.
At the same time, the Lunar Orbit Construction Committee held a press conference at the Jinling Hotel to publicly report the latest progress of the rescue operation to reporters from major media.
At this moment, his assistant walked over from the side.
At almost the same time, the Xiaguang spacecraft, which was performing a mission in lunar orbit, received the news and immediately launched a preparatory plan. After the Yuegong space station completed the supply of working fluids and living supplies, it followed the route calculated in advance by the ground command center. Channel to Mars.
Therefore, it will take 3 months for a BFR rocket to travel to Mars across a distance of tens of millions of kilometers.
"Yes."
Is this treating him as a cash machine
"gentlemen… "
About two or three months ago, they met from a distance in outer space orbit.
[I feel ashamed of NASA.]
[I feel ashamed of NASA.]
On a shorter distance scale, due to the huge thrust of chemical propulsion, the spacecraft can reach a very high speed in a short period of time, so it is more advantageous in terms of flight time overall.
[I feel ashamed of NASA.]
However, if the distance scale is enlarged to millions of kilometers or even tens of millions of kilometers, it is another situation.
Damn it, you can build a new Xiaguang!
[I feel ashamed of NASA.]
"What's wrong?"
"What documentary?"
"This is the Xiaguang. We have completed all flight missions and are requesting instructions for the next step."
In a deep and dark space, the Xiaguang spacecraft, which had delivered the Yuegong station astronauts to their destination and completed the supply of working fluids, was slowly separating from the Yuegong space station.
…
Scan code and pay in installments are supported.
Looking at Director Carson with a sullen expression, the assistant hesitated for a moment and hesitated to speak.
He opened his mouth and asked in a forced voice.
"The ground command asked us to wait."
On a shorter distance scale, due to the huge thrust of chemical propulsion, the spacecraft can reach a very high speed in a short period of time, so it is more advantageous in terms of flight time overall.
[Until now, I don’t know why "Mars Diary" was stopped. It was not because of the high cost of communication or the sandstorms on Mars. It was purely because our White House and NASA wanted to hide the truth... ]
Speaking of this matter, Liu Biao couldn't help but feel emotional.
[Don’t tell me about the difficulty of rescue. Now I seriously doubt that NASA has no intention of saving people at all!]
"A bad news..."
"A bad news..."
Speaking of this matter, Liu Biao couldn't help but feel emotional.
But for Xiaguang, which sets off directly from the lunar orbit, one month is enough.
Looking at the subordinates of his mother-in-law and mother-in-law, Carson said impatiently: "Stop talking nonsense and speak quickly."
This is even after missing the optimal launch window for the Hohmann transfer orbit. If the relative position of Mars and the Earth happens to be at the optimal launch position, it may not even take a month to complete a mission from the moon to Mars. flight.

[Don’t tell me about the difficulty of rescue. Now I seriously doubt that NASA has no intention of saving people at all!]
I didn't have time to say hello and watched them fly away.
Especially the rescue plan that was launched within 15 minutes immediately made the staff of the NASA Ares Project Ground Command Center blush.
The assistant smiled bitterly.
[Don’t tell me about the difficulty of rescue. Now I seriously doubt that NASA has no intention of saving people at all!]
…
Upon hearing these words, Director Carson's heart suddenly thumped, and he secretly felt something bad.
Speaking of this matter, Liu Biao couldn't help but feel emotional.
But where the bad news came from, he couldn't tell.
As a result, the Chinese side did not conduct any budget assessment. In less than 15 minutes, they determined the channel and dispatched a rescue team, which efficiently destroyed more than one street.
"I saw it." Opening his half-closed eyes, Xu Zhenghong sat up straight in his chair and reached out to press his helmet. "This is the Xiaguang. It is heading to the predetermined airspace and preparing to switch routes..."
"The name seems to be... The Martian."
Scan code and pay in installments are supported.
But where the bad news came from, he couldn't tell.

The assistant smiled bitterly.
"What's wrong?"
If you want to understand the differences in the advantages and disadvantages of electric propulsion and chemical propulsion, you must first understand a concept that all junior high school students understand, and that is acceleration.
15 minutes ago.
"A bad news..."
"What documentary?"
15 minutes ago.
In order to save face and show its determination to bring its own citizens home, after realizing the seriousness of the matter, the White House urgently announced that it would bear the entire budget of the rescue plan.

However, less than five minutes after the announcement was issued, NASA received a bill sent from across the Pacific Ocean.
[Don’t tell me about the difficulty of rescue. Now I seriously doubt that NASA has no intention of saving people at all!]
"What documentary?"
"The name seems to be... The Martian."
$1.7 billion!
This move almost made the United States so angry that he vomited blood.
Ten minutes ago, the news reached the Jinling Space Launch Center, and the staff who finished the navigation work immediately returned to work.
Carson: “…”
15 minutes ago.
"gentlemen… "
After seeing this bill, Director Carson was almost furious.
"What documentary?"
He doesn't want to say anything now, except for a few words...
Not only that, China's open, transparent, serious and responsible attitude towards "humanitarian" rescue was in sharp contrast to NASA's previous push and pull, and for a time, all the work of the Ares program ground command center was paralyzed. The personnel, as well as those who supported the Ares project, felt ashamed, and the direction of public opinion changed overnight.
"The name seems to be... The Martian."
After seeing this bill, Director Carson was almost furious.
