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

"The 21st century is an era of rapid changes and rapid development. Space is the most important issue in the 21st century. Whoever takes the lead in space will control the future."

——Media excerpt from the opening speech of the Huayin Conference.

This sentence, together with the news headline "Two rockets, two skies, one moon" published by CBS, became a popular saying in early July.

Of course, John was not to be outdone, saying that he would hold a joint meeting on international space cooperation and planetary defense on July 4, around the time Artemis 2 arrived on the moon for its landing mission, and would invite all members of the Artemis program. countries and all allies.

The meeting location was chosen near the Great Smoky Mountains National Park in North Carolina, and the agenda is expected to last until July 20.

Using a state to benchmark a county-level city fully demonstrates the importance John attaches to the Huayin Treaty Organization.

It is also expected that the number of member states of the North Carolina Conference will exceed 27, which is twice as many as the member states of the Huayin Treaty Organization.

"This North Carolina Conference? What is its purpose?"

In Qiongzhou, Academician She sincerely expressed his doubts.

Lin Ju shook his head. John really thought about everything. If it were to compare with the Huayin Treaty, the many organizational agreements they signed would be enough.

To be honest, he is not optimistic about the Huayin Treaty. Only four of the twelve members have aerospace technology, three of them have independent launch capabilities, two have manned transportation means, one has large-scale space launch capabilities, and the rest Half of the eight are money bags and half are pits.

But... no matter what, it is the first step taken.

On the surface, public opinion around the world is now in a state of excitement.

Although the second space race has essentially arrived, a tit-for-tat Cold War has not occurred. On the contrary, global trade volume is still rising. Economists are very optimistic about the future trend. Space competition seems to be peaceful competition.

24 hours have passed since the launch of the two rockets. CCTV took the lead in calculating the domestic ratings data:

The viewership rating is 45%, the cumulative number of viewers exceeds 1.12 billion, and the video network platform exceeds 800 million (including repeat users). It is estimated that the number of live broadcast viewers worldwide exceeds 2 billion, of which Asia accounts for the majority, especially Korea, island countries and Southeast Asia. Mainly, the ratings in Korea and island countries even exceed those in China (?).

The global viewing data released by Artemis 2 also exceeded 2 billion, and the highest number of simultaneous live online viewers on YouTube exceeded 24 million (NSF forwarding channel), setting a new record in history.

Even though Bloomberg published a sensational report such as "NACA has lost the moon," in fact the public did not react much.

The launch interval between the Long March 10 Yaosan and the SLS was less than 30 minutes. When they entered the Earth-moon transfer orbit, reports were sent out almost at the same time. It is not excessive to use simultaneous departures.

Now people all over the world are curious: Which spacecraft's astronaut will land first on the first footprint of the new century?

According to the public content, the media speculated that the first person to launch the lander on Dawn 3 was Zhang Zhiguang, and that the first person to launch the lander on Artemis 2 was Victor, a black man. There was already a gambling website on the Internet for betting, and it attracted a lot of people in just one day. Hundreds of millions of funds were raised.

Before the landfall phase began, the public attitude was unanimous: celebrate.

The base has received information from the Chengdu Air Force to temporarily suspend or restrict the flight area at Hushan Airport, because fireworks may suddenly rise from the ground no matter it is day or night, which is fatal to most low-flying propeller aircraft.

In mid-July of the year, the fireworks market across the country was suddenly brought to prosperity by Shuguang 3. It is said that all major urban areas have added checkpoints at major imports and exports. There is almost a half chance that the fireworks can be obtained from the trunk of a private car entering the city. Turn out the fireworks you are carrying.

The flight show that the flight school originally planned to organize was postponed because of this hidden danger. It is now tentatively scheduled to be after the moon landing is successful.

Aramco also has the momentum to restore the spirit of the last century. The tense pursuit of each other in the previous year has been temporarily put aside. Ordinary people believe that the launch of Artemis 2 will bring them back to the peak of the last century - -?

Although everything was normal during the launch phase of Artemis 2, aerospace companies around the world can see the haste and chaos of multiple changes to the launch plan.

Out of humanitarianism, the boss asked Lin Ju to speak out to take a vaccination in advance and occupy the moral high ground in advance: You are the one who thinks you are right and have to compare. If there is an accident, don't blame us.

After the launch of Shuguang-3, the Aviation Development Commission urgently conducted an analysis of the Artemis-2 mission and discovered many doubts.

First of all, from public leaks, the Blue Moon lander suffered frequent malfunctions during its development in the first half of the year. Even the BE-7 engine with low thrust suffered serious accidents such as shutdown. Moreover, there is evidence that its configuration is designed to be able to The launch of the Falcon Heavy has undergone major changes, and the overall center of gravity has changed greatly.

In just two or three months, it went from the verification stage with frequent problems to a stable formal machine manufacturing process?

The second is the on-orbit fueling technology, which requires more than 20 tons of fuel, and the technical difficulty required will also increase significantly. How long did it take Raytheon to develop that fuel tank?

Third: Landing site survey. Before the Apollo program, Aramco conducted 7 "Surveyor" unmanned soft landing programs. The Aviation Development Commission also threw so many robots into the Qom Crater. Aramco only had one "Isis" , can accurate landing data be obtained?

The Aviation Development Committee raised serious doubts about the entire landing stage and believed that the probability of accidents was extremely high.

Although the Apollo program's lander also did not undergo actual testing, the development period was at least twice as long.

And if something goes wrong during the landing stage, losing control on the moon without an atmosphere means death, and no one can save it.

How would the situation change if there were casualties on Artemis 2?

…

Space Center Houston.

The SLS rocket completed its mission, and even after the manufacturing and testing time was compressed several times, it still successfully sent Artemis 2 into the transfer orbit - although it was not as smooth as the outside world saw, and there was a small problem in the middle.

The problem lies in the SRB, which should not be the problem. The solid booster of the SLS rocket is improved from the SRB of the Space Shuttle Launch System. The four combustion chambers are increased to five. For solid propellers, it can only Considered a routine operation, the risk is not high.

It was supposed to continue burning for 126 seconds and then separate, but during yesterday's launch, the rocket's right booster shell sensor abnormally issued a pressure warning at the 98th second of the launch. Claire decisively requested to abandon the two boosters in advance, so the separation time It's 110 seconds ahead of schedule.

The SRB worked for 16 seconds less, which means that the rocket lost 3,200 tons of thrust for 16 seconds.

Fortunately, the design of SLS Block1 has a lot of redundancy. Its first stage had the potential to send more than 130 tons of payload to low-Earth orbit. The Block1 version LEO capacity is only 95 tons. The first stage relied on excess fuel to work for a while, and still Send the second level up.

After salvaging the right SRB booster that fell into the sea, it was found that there was an obvious crack on the shell with traces of explosion. If it was separated and the fuel would burn through the shell in a few seconds at night, the direction of the flame was in the opposite direction. The orange tank of the core stage, when the time comes, the entire SLS rocket will turn into a huge firework under the combined action of liquid oxygen, liquid hydrogen, and polybutadiene-acrylonitrile. If the escape tower is not activated in time, the four astronauts will Not even the ashes of the members will be left, they will only become part of the atmosphere.
