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

Jeff Bezos finally reappeared in people's sight 48 hours after the space capsule landed.

First, let’s clear up the rumors: there is nothing wrong with the capsule, Jeff is not dead, and New Shepard is safe.

As for why Jeff hasn’t shown up for so long? The reason is that the world's second richest man, who bravely flew into space on his own rocket, broke his chair and fractured his tailbone when the capsule landed...

Inside the "New Shepard" space capsule were six swivel chairs arranged in a ring. Maybe the quality of one of them was not very good, causing it to break the moment it touched the ground. Then the unlucky Jeff Bezos was killed. He was quickly carried into the operating room.

After the operation, his body was fine, but obviously this could be regarded as a space flight accident, so Blue Origin tried to cover it up, but failed.

But in any case, Jeff did prove his mettle, and Blue Origin began to promote its tickets with great fanfare:

$25 million.

It is US$3 million cheaper than the original world line, but this figure does not seem to be very cost-effective nowadays, especially when you can only experience weightlessness for a few minutes.

Not to mention competing with Xinyuan, but the "Manned Dragon" spacecraft manufactured by SpecaX in Texas next door is also about to undergo a test flight. The ticket price advertised by Lao Ma last year was only US$15 million.

…

"This is the 'Feitian III' lunar surface work spacesuit we developed."

At the Beijing headquarters of the space agency, the person in charge here introduced to Lin Ju the red and white space suit samples on display.

"In the past, our extravehicular spacesuits did not consider lower body movements. Feitian III has a semi-rigid structure and can support 8 hours of activity. After wearing it, astronauts can complete various tasks such as driving a lunar rover, collecting samples, and setting up camps.

Moreover, Feitian III has an important technological advancement. Although its material is soft, it will not expand too much after being inflated and affect body movements..."

Feitian III, since the launch of the Dawn Project, the development of lunar landing spacesuits has also started simultaneously. The space agency has developed a series of sub-models directly based on the "Feitian".

Although Feitian III has many technological breakthroughs, the unpowered spacesuit is just like that and is inconvenient to put on and use.

Because the astronauts in the spacesuit need air and air pressure, and the outside of the spacesuit is almost a vacuum. The huge air pressure difference between the inside and outside will cause the spacesuit to bulge like a balloon, as if it is covered with honey snow ice. Although the city mascot costume has better visibility, it still has great restrictions on movement.

Astronauts wearing such spacesuits can do easy tasks, but if they are required to do more delicate and complicated tasks, even if they can barely do it, it will consume a lot of energy.

"Okay, okay, let's not brag in front of Mr. Lin."

Academician She, who was accompanying Lin Ju, smiled and stopped the person in charge here from continuing, and instead said:

"Xinyuan's hard style... should be called exoskeleton. It's much more advanced than us old guys, and it's stronger than Artemis's."

The "ares" spacesuit of the Artemis Project mentioned by Academician She is also a semi-rigid structure, but with rotating joints on the lower limbs and a hard-shell vest design on the upper body, many improvements have been made compared to traditional extravehicular spacesuits. Much more flexible and indeed more advanced than Feitian III.

There is no way, the Feitian III design work was too rushed, it is necessary to be conservative for safety reasons, and we can adjust it slowly in the future.

Xinyuan Company is also designing its own lunar space suit. They are not in a hurry, and based on the "Warrior" series, they decided to develop the "Pioneer I" rigid space suit containing a mechanical exoskeleton in one step.

The pioneering I type, although the main part is still a textile one-piece, the upper arms, lower arms, torso, legs and other parts are all wrapped with a fitting metal/non-metal hard shell, so that the limbs and torso expand due to the difference in air pressure. restrictions to allow astronauts to move more freely and flexibly.

It is also equipped with an exoskeleton design, which is divided into basic type of passive exoskeleton and type A of active powered exoskeleton.

Passive exoskeletons mainly disperse the stress on the upper body through reasonable support design, and at the same time can protect astronauts from falling injuries; active power exoskeletons are very powerful, and even equipped with jet RCS, which can empower astronauts on the moon and Mars. The ability to stay in the air for a short period of time and move quickly, taking full advantage of low gravity, can also do some heavy physical work.

Of course, the development of these two types of exoskeletons is also very difficult, especially the monocoque design. Obviously, the aerospace industry has thought of it for a long time, but it has not been able to produce it due to current technology, and there are many technical problems that need to be overcome.

The space agency has also invested an initial 70 million in this project. Maybe after the development of Type I, it will be registered with the space agency as Feitian IV...

Lin Ju suddenly flew to the capital again. Naturally, he was here for the 304 injection. Coming to see the space suit was completely a pretense.

However, Academician She was obviously very happy about Lin Ju's arrival. After the two chatted for a while, Lin Ju finally started to try to guide the topic.

"Chief Master She, Institute 507 was researching superpowers back then. Did you really discover anything?"

"Super power?" Academician She was stunned. With his qualifications, he naturally knew what happened in Institute 507 back then.

"Well, hey, this is complicated. There are many factors involved that you won't be able to explain for a while, but one thing I can tell you clearly is that there are no superpowers.

However, some of the anecdotes about strange people are indeed true, but the most true one is that he has a super memory, which is indeed a photographic memory. The rest of the things about walking through walls, being invulnerable, and not afraid of fire are all fake, at least they are not super powers. Are you curious about this? ? Mr. Qian has a book that mentions these things. I will look it up for you later...

Why are you paying attention to this now? Such mysterious things are fruitless. "

Lin Ju: "That's not true, but our base has some recent achievements, so I thought of it."

"Results, superpower results? That's right. Your rocket success rate is so scary. I should have thought of it, but what superpower can..."

"Ahem!" Lin Ju quickly interrupted Academician She who said "I have discovered the truth" and quickly began to explain (blindly) explain (edit):

"That's right, aren't we working on the Qianjin space station? We collaborated with universities on a project to study how to prevent or delay osteoporosis and muscle atrophy in no gravity or low gravity. Naturally, we decided to use drugs. Methods of treatment.

A few years ago, they unexpectedly produced some results. I planned to carry out this project but it was difficult to control it, so I came here to get some advice. "

"Oh." Academician She was greatly disappointed. He thought it was something extraordinary. The space agency had already done similar research.

But now he also understands that this is the reason why Lin Ju flew over again, and he is somewhat interested.

"Why are the results so great, why would you bother to come here in person?"
