I ask you to build tractors, but you build rockets?

It was more than an hour after the Aviation Development Committee received the news. At that time, Lin Ju's first reaction was: How could it be such a coincidence?

Due to the time difference, it was already past six o'clock in the morning on the 23rd China time.

A few days ago, Xinyuan-3 moved the three spoke cabins to the three axial cabin sections of the Forward space station, and the Pioneer is preparing to launch with the truss on the 24th for installation work.

At this time, there are still more than 20 hours before the launch. The Pioneer has been combined with the Xinyuan-2A modified rocket and can be launched after refueling.

The Pioneer is much easier to carry out rescue missions than the H1, especially the super large cargo hold with a length of 35 meters and a width of 8.4 meters.

The size of the Dream Chaser is 9 meters in length and 7 meters in width. The Pioneer's cargo bay can fit three Dream Chasers...

So Lin Ju immediately issued a statement, and then the 20 astronauts from the four H2M crews began to draw lots to see which five people could win the title of Space Hero.

However, when the Aerospace Development Commission expressed its goodwill to NACA, the latter did not seem to appreciate it. At least it kept denying on the phone that the Dream Chasers could not return, and only said "thank you for your colleagues' concern."

In fact, they did not appear so calm to the outside world. Engineers from Lockheed Martin and Sierra Nevada Corporation were frantically searching for the specific cause of the failure, otherwise the Dream Chaser would not be allowed to re-enter the atmosphere.

And time is limited because there are 9 Dream Chasers on board! 9 astronauts!

Oxygen and food are trivial matters. Emergency food can sustain normal activities for 7 days, and oxygen can also last for 7 days, but there will always be too much inconvenience for 9 people crowded into a small space.

The first is a physical problem. There is really no bathroom on the Dream Chaser. The best solution is to pull a piece of cloth and use a simple folding toilet.

The second is the tightness of the crew cabin. Now the nine astronauts dare not take off their masks. Otherwise, if the connection port suddenly leaks, it will be the most serious accident in the history of spaceflight.

Six hours after Dream Chaser was launched, the ground finally determined the cause of the failure.

Eamon grabbed the sweaty Lockheed engineer and asked him what was going on.

"The hatch, the hatch is not stuck. It is a mechanical component failure. It should be that a connecting rod is deformed and cannot be opened."

"Maybe? What is should?"

"No, it's for sure. It's that part. I can confirm that the interface does not withstand any force or high temperature during the launch process. There can be no problem, it can only be an internal problem."

Eamonn: "Then why did the connecting rod you mentioned fail?"

"Because the Dream Chaser needs to lose weight while still holding 9 people, and the interface needs to be compatible with 3 different types, we must improve it."

Eamon: “…”

Well, the several docking ports currently available on the International Space Station not only come in several sizes, but also come in several types with the same size.

ISS has been developing compatible interfaces more than ten years ago, which brings convenience but also complicates the structure.

But the good news is that since there is no problem with the hatch seal, it means that at least there will be no risk of burning the astronauts when returning to the atmosphere.

But he still refused to give up: "Can't we find a way to dock with the space station? The hatch is not broken."

"I can guarantee that the Dream Chaser is safe if it is not opened, but if it is forcibly opened... regardless of whether it is possible or not, the Dream Chaser cannot guarantee that the person will be brought back to the ground safely."

Eamonn wanted to say something else, but someone stopped him at this time. It was the assistant of the boss's office and Director Claire's secretary.

The two approached together and expressed NACA's decision without expression:

"Eamonn, bring our astronauts back."

…

"The Space Shuttle Dream Chaser landed safely at the Kennedy Space Center. All nine people on the flight had their vital signs intact and no injuries were reported."

"NACA, Lockheed Martin, Sierra Nevada, and Raytheon formed an accident investigation committee and the Dream Chaser's manned missions were suspended during the investigation."

"Stephen Bowen's heroic actions saved the entire crew and is understood to be dedicated to animal protection."

"The Aviation Development Committee expresses great concern about the safety of manned flights and will implement a new generation of safety standards."

"..."

On the morning of October 22, Aramco time, the Dream Chaser returned to the ground in a thrilling manner after being stranded in space for more than 10 hours.

After landing, the interface was broken open by a cutting machine, because all attempts to open it failed, and the cut part was immediately given to the investigation team to analyze the cause of the accident.

The Dream Chaser was immediately grounded, and the next two aircraft under construction also had their docking interfaces vacated. Obviously, they will be postponed again.

Fortunately, the nine astronauts were safe and sound, but most of them had changed diapers and they did not dare to take off their spacesuits the entire time in the sky.

John directly issued an order from his boss to thoroughly investigate the cause of the accident. An accident occurred on the first day he took office. Although he was fine, his face was almost completely lost.

Boeing and SpecaX are a blessing in disguise. The latter's Manned Dragon spacecraft just completed an unmanned test launch the day before yesterday and is already preparing for manned flight. Although the former's Starliner spacecraft is progressing slightly slower, because it is all traditional technology, it looks better than Are Dream Chasers safer?

But what NACA should be worried about now is what to do with the nine astronauts. The longest of the nine people waiting to be replaced in the sky has been postponed for more than 150 days. It is unreasonable to stay any longer.

Waiting for Dream Chaser? No, the next Dream Chaser mission will definitely be unmanned anyway.

But if we don’t wait, what can we use now?

ISS reluctantly turned its attention away from the other side of the ocean and returned to Lucia.

Mao Zi: The Alliance spaceship must be stable. The laws of our ancestors cannot be abolished!

The H2M crew gearing up to win the title of hero: Sigh.

…

"Mr. Guo..."

"No, no, no, just call me Ye Changsi, or just Lao Ye. I'm twenty years younger."

"Then you can call me Xiao Lin...that old Ye, I want to ask..." Lin Ju looked forward to it with a hint of nervousness.

"You have participated in the development of eggs and stars. That configuration..."

Ye Changsi: "Hey, you have to ask Lao Yu and Lao Chen about that. They are still here. I am just an errand boy."

"Don't say that..."

After ending the sensitive topic, Lin Ju was in a great mood.

Two A+ level legendary scientists control the operation of the base. He can do almost nothing but give orders. Coupled with the super overall BUFF gains of the two, the scientific research capabilities of the base have increased significantly.

After discussion, Ye Changsi was in charge of two parts: Qingshan Base and Laser Laboratory.

Both are extremely important confidential departments of Xinyuan, and they are easy for Ye Changsi to pick up, and they happen to be the parts that interest him.

Before waking up as Ye Changsi, he had gone through systematic and long-term study, and had basically digested all the cutting-edge physics achievements of mankind for decades. At this time, he still had the identity of a scientist standing at the forefront of current human physics.

After a few days of contact with Lin Ju and a rough grasp of the base's situation, he had his own plan in mind. The freedom of the legendary A+ level scientist was also part of the reward.

"Xiao Lin, have you seen the news about EAST a few days ago?"

"Oh? Ignition at 80 million degrees?"

Lin Ju immediately remembered that a few days ago, Huaguo's own EAST plasma-confined superconducting tokamak controllable nuclear fusion device was ignited at 50 million degrees Celsius some time ago and then ignited at 80 million degrees Celsius, but he didn't think much of it. care.

Controlled nuclear fusion? Later generations have ignited more than 100 million degrees, but there has been no breakthrough.

Ye Changsi: "I think we should carry out some controllable nuclear fusion research."
