The oxygen circulation system is broken, and it is an absolute nightmare for the astronauts on the Martian spacecraft.

But fortunately, they have backup systems, which every spacecraft has.

After all, in space, you don't have emergency equipment, that's not.

"Activate the emergency equipment."

"I activated, but nothing happened."

“……”

Several astronauts were dumbfounded, they couldn't figure out why the oxygen cycle equipment was broken, and even the emergency equipment was broken.

Isn't it good when the earth is tested and checked?

"There is oxygen circulation equipment in the landing module, and there is also oxygen circulation equipment in the rover, and the oxygen circulation equipment that was originally intended to be used in the construction of the Mars base is in the outer module, and we can only dismantle one now, otherwise we will not be able to hold on to Mars with our oxygen reserves."

"Our oxygen can last for 15 days, so let's contact the command center first."

There is no problem with contacting the command center.

Although at this time, they are already far away from the earth, a full 13 million kilometers.

But it's acceptable, after all, the delay of a contact is only 86 seconds, and this contact is not a real-time call, but a message in the form of a data packet, which can send a lot at a time.

In order to support the Mars mission, a brand new communication satellite has just been launched, although it is not quantum communication, but it is also the latest technology, much stronger than the previous antique.

Soon, they sent back the current situation of the Martian spacecraft or the data recorded by the spacecraft's computer.

A minute and a half later, NASA's command center received the packet.

And then...... Confused.

Broken oxygen circulatory system?

What about funny?

This thing is the least likely thing to break, even if the solar panels are replaced, the atomic clock is broken, and the oxygen circulation system will not break.

It's a pity that such an impossible thing has happened now, and even the emergency system has broken down.

A group of NASA experts calculated that it was impossible for the Martian spacecraft to return.

After all, the power of the Martian spacecraft is the fuel engine plus the Hall thruster, but the main power does not come from the engine, but accelerates through the Earth's orbit, that is, the gravitational slingshot.

Now halfway through the Mars spacecraft, there is no acceleration in the Martian orbit, and it is possible to slow down the fuel engine alone, but it is impossible to accelerate back to Earth in a short time.

Therefore, after research, NASA experts absolutely asked them to dismantle the oxygen circulation system of the Mars base and take it to the living module for use.

As for the Martian base, forget it, land on Mars and load a wave, and return quickly.

After receiving the message from the command center, the two astronauts put on their spacesuits, went to the outside of the spacecraft, and took down the equipment on the outer cabin.

More than forty minutes later.

The oxygen recirculation system equipment box attached to the outer compartment was removed from the outer compartment and transported to the interior of the ship.

A group of people open the equipment box, only to find six spacesuits and a bunch of oxygen tanks.

"Fack!"

"Shet!"

“*******”

When they saw the contents of the equipment box, several astronauts exploded.

Turn on the communication equipment, scold into the microphone, then start to explain the situation, and finally scold a few more words before clicking to send a message.

A minute and a half later, NASA received the message.

A group of people were scolded and confused.

Then, when they heard that there was no oxygen circulation equipment in the equipment box, they also broke out in a cold sweat.

Just kidding, this is no small matter.

Convene a meeting of personnel, contact the above, and ask the upper authorities to hold the supplier accountable and investigate the truth of the matter.

Why did the oxygen circulation equipment turn into a spacesuit and an oxygen tank.

Check the data, calculate the data, and a group of experts calculate the results.

In the absence of oxygen circulation equipment, the astronauts leave the living module and all go to live in the landing module, using the oxygen circulation equipment of the landing module and the rover, plus the remaining oxygen, it can last for 37 days.

In other words, this Mars mission will definitely not be completed.

Moreover, they want to save people, but they also have powerless hearts.

Every hour that passes, the Martian spacecraft will be 36,000 kilometers away from the Earth.

I had no choice but to ask Hua Guo for help and see if Hua Guo could help.

On this day, Ann smelled up and washed up, and hadn't eaten breakfast yet.

Director Shen's phone called.

"What's that? The Martian spacecraft in the United States is broken, and you want to ask us to help rescue it? After An Wen received the call, he was stunned.

"Yes, according to the news sent by the United States, the oxygen of the Mars spacecraft can only last for 36 days.

They have brought the Martian spacecraft back to home, and they have started the fuel engines, running out of fuel for acceleration. According to calculations, they can only reach a maximum of 600,000 kilometers from Earth before they run out of oxygen.

So, the astronauts on the Martian spacecraft need us to come to the rescue, otherwise they can't return to Earth's orbit.

The above meaning tends to rescue, but the specific performance of the Black Dragon, only you know best, do you think the Black Dragon can go to the earth orbit 1 million kilometers away for rescue? ”

After listening to Director Shen's words, An Wen nodded.

"Theoretically, there is no problem with the Black Dragon.

But in reality, the Black Dragon is just a space shuttle, and there is no problem in navigating the Earth-Moon orbit.

But the distance of 2 million kilometers back and forth, in case of an emergency, it is difficult to say.

But it doesn't matter, if the above really wants to rescue, I can drive the Phi Phi Shrimp to the rescue, as long as it doesn't fly out of the solar system, the Phi Phi Shrimp is no problem at all. ”

An Wen said indifferently, just rescue, small problem.

In fact, the Black Dragon can also be competent, but it is not so safe, so it is better to use the Phi Phi Shrimp.

"Okay, I'm relieved to have your words, I'll report to the above, the specific rescue plan, and I'll inform you later."

"Don't tell me, you can do this kind of thing, my research is not finished yet."

Hanging up the phone, An Wen stopped thinking about this problem.

Originally, he also thought that when the Martian spacecraft was about to arrive on Mars, he would set off again.

As a result, it was only a eighth of the way to fly, and it hung up.

Engage in wool, white is looking forward to it.

On the other side, Director Shen reported An Wen's original words to the above, and then held a meeting above to study the rescue plan.

You say there's nothing to study about this thing?

It's funny.

There are a lot of things in this, that is, An Wen doesn't think about it.

The above meeting was studied for more than two hours, and then contacted the United States.

The general meaning is very simple, we can help you save people, but you have to provide a spaceship, and we will send the spaceship to your astronauts and let them fly back on their own.

As for us using a spaceship to pick them up, that is not possible, because the spaceship is not ours, and we also borrowed it, which is inconvenient to visit and easy to leak trade secrets.

At the same time, this spaceship loan, please trouble first, not much, just 200 million dollars.

Then please hurry up and build the spaceship, and we can send the spaceship over.

This rescue plan is well-founded and convincing.

In the end, the United States had no choice but to agree to this rescue plan.

But just when the two sides negotiated the terms and were about to reach a cooperation, the communication was cut off.

Why.

Because the satellites of the United States have been scrapped again.

After Betelgeuse's explosion, gamma rays finally arrived in the solar system and swept across the entire solar system.

The last afterglow of the star, the glow of the supernova explosion, descended on Earth at this moment.
