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

At the press conference, Claire, as the highest authority of NACA, came forward to explain the cause of the Dream Chaser accident a few days ago and to answer questions about the subsequent space program.

First, the accident investigation report of the Dream Chaser came out. After analysis by Lockheed Martin engineers, when the Dream Chaser required weight reduction, it also put forward technical requirements for the interface, which required a 20% reduction in mass compared with the original.

In order to achieve the goal, engineers have simplified the internal structure to a certain extent, resulting in a place where the strength is a bit inadequate. In addition, the design position is coincidental, and there is a probability of deformation due to pressure issues in a vacuum environment.

The solution is also simple: switch back to the original mature design.

The Dream Chaser does not lack the mass of the dozen kilograms of the docking port, and it does not take too long to modify it. However, the Dream Chaser still needs to be inspected as a whole, so the next unmanned test flight will be around the beginning of March, and then it will be manned. flight.

As for the nine astronauts on rotation...

Claire: "After internal deliberations at the ISS, we will not rule out using vehicles other than the Dream Chaser for subsequent personnel rotation missions."

Reporter: “Is it Lucia’s Soyuz spacecraft or Xinyuan’s space shuttle?”

Claire: "Task bidding is a commercial practice, and no more information can be disclosed for the time being."

Reporter: "Will the Dream Chaser's accident affect the follow-up missions of the Artemis program?"

Claire: "The Artemis project is currently progressing smoothly and is moving forward steadily in accordance with NACA's plan."

Reporter: "So the Artemis 2 mission will still be carried out in October 2017, carrying astronauts around the moon?"

Claire: "Yes, no later than this time."

In fact, Claire was a little happy at this time. Everyone thought that SLS could only be built once a year, but who knew that the next SLS was expected to be launched in August?

According to their manufacturing schedule, the Long March 10 of the Aerospace Development Commission will be launched from June to July at the earliest. In addition, the Artemis program has added a heavy Falcon rocket, the launch time will be shorter, and the actual progress will only be faster. NACA will soon Go ahead!

In the face of returning to the moon, the small setbacks encountered by the dream chasers were insignificant. Although it was a bit embarrassing for John, it actually had no catastrophic impact.

The follow-up Dream Chaser 2 and 3 are also about to enter final assembly. This kind of miniature space shuttle can be built much faster than the old space shuttle, which takes several years to build one.

But when he thought of large space shuttles, he felt a little embarrassed. The speed at which a private aerospace company in Xinyuan put two H2Ms into service at the same time was simply unbelievable to him, and they were both giant objects weighing more than a hundred tons.

Wait, today seems to be China’s New Year’s Eve? It seems that he has also made an appointment for YouTube’s Qianjin space station to be stationed for the first time and for the New Year’s Eve live broadcast.

What does the interior of a 14-meter-diameter super-large cabin look like? How spacious should it be?

I heard that they also innovatively use a concentric circle structure. Is this an optimized design due to centrifugal rotation? No, let more people take a look and analyze it to accumulate experience for NACA’s centrifugal space station.

…

"Come on Deng Lei!"

"Li Sheng, hit the bottom lane, bottom lane!"

In the pilot cabin of the Advance, a New Year's Eve friendly match is taking place.

Thanks to the super large diameter of 14 meters, even if the center of the pilot cabin is occupied by equipment, the space left for the personnel to be divided into two parts is very wide, wider than an ordinary living room. The length of more than 40 meters makes the activity space excessively spacious.

In addition to trusses and supplies, the materials brought by the Pioneer also included badminton, table tennis tables, darts and other sports equipment.

Due to the loss of gravity, Deng Lei and Li Sheng not only need to pay special attention to the correction trajectory that is completely different from that on the earth when playing badminton, but also need to stabilize themselves at all times.

Because Deng Lei used too much force to catch the ball in the air, he lost his point of focus and started rolling erratically on the spot. However, he still found time to catch the ball in reverse in an inverted posture that is impossible on earth.

The other three people were currently preparing materials at Li Sheng's feet, which was the other half of the space. In the two days after entering space, they only installed less than 10% of the trusses. They had to wait until New Year's Eve. The rapid construction phase will only begin after night.

Of course, from tomorrow to the sixth day of the first lunar month, if you work overtime on holidays, you will receive five times your salary, as well as a special New Year subsidy.

No one has any complaints about working overtime, because the astronauts on the Tiangong Space Station, thousands of kilometers away, have repeatedly expressed their strong desire to work to the ground, even if they do not receive overtime pay.

Compared to doing small experiments on the Tiangong Space Station, driving H2M to build a centrifugal space station seems to be much more interesting. Unfortunately, they currently do not have H2M driver's licenses, and they have to rotate through it to get the chance.

The ground has sent several H2M flight manuals to the Tiangong Space Station during a recent supply mission. Aspiring astronauts have nothing to do but chew on the 5 cm thick flight manuals and the emergency maintenance index catalog of the same thickness...

…

"Is it true that we can't use No. 3?"

"Mr. Lin really can't do it... Let the No. 3 rocket come with thousands of tons. These are not fireworks, this is a small nuclear bomb..."

Director Huang was resolute, and Lin Ju could only move his eyes to the Long March 7 on the launch tower in disappointment.

According to Xinyuan's tradition, this year it was originally planned to use the Xinyuan-3 rocket to launch fireworks, but the latter's first-level transport capacity can send a mass of almost two thousand tons to an altitude of tens of thousands of meters. The Qiongzhou Launch Administration really did this this time. If you don't approve, you can't go through the back door.

Two thousand tons of fireworks, if they were equivalent to TNT, could wipe out the city center. No, no, no, this is too exaggerated.

Of course, this does not mean that the fireworks show has been cancelled, but the fireworks manufacturer has turned into a space agency. They took out a Long March 7 and sent a 50-ton special fireworks can to a high altitude to detonate.

Unlike Xinyuan, which is rough in work, after the Long March 7 was successfully reused, the space agency secretly found manufacturers to customize it and made a gift for the Spring Festival several months in advance. It is said that it can explode a rooster that can be observed across the strait. Compared with Last year's Super Flare art was much richer.

But Lin Ju was still a little unconvinced. Xinyuan's New Year gift was for Pioneer's robotic arm to grab a truss and perform traditional martial arts. Although it was quite creative, he couldn't watch it from the ground!

Ye Changsi, on the other hand, didn't think it mattered. He felt that it was luxury enough to build spiritual culture with rockets that had to be accounted for every launch in their era. When he saw that the space agency was also led to amplify the fireworks, he couldn't help but sigh:

"If Lao Qian could see this scene when he was alive, I'm afraid he would be very happy."

Lin Ju: "If it were Mr. Qian, would he think it would be more interesting to explode a hydrogen bomb in outer space? It's like an artificial little sun."

Ye Changsi raised his head and thought seriously: "The effect will definitely be better, but it may affect the communication system of satellites and aircrafts, and we may have to pay a lot of money, forget it.

We can't make a small artificial sun yet, but we can still make a small moon. "

Lin Ju: "What? The moon?"

Ye Changsi: "Some time ago, the Sichuan government envisioned building a city that never sleeps. It plans to launch a reflector into space to cover the urban area to achieve high-brightness lighting to save electricity and create unique IP."
