Musk did another big thing, SpaceX's "Dragon spacecraft" took four passengers into the sky, this space exploration is very different from previous launch missions, because two of them completed the first commercial spacewalk of mankind.
This is the first time that a private space company has carried out space exploration without a government organization, and this is a remarkable achievement! So what is so special about the new aerospace business model created by Musk?
Let's find out!
1. Musk's "Polaris Dawn" space mission
This time, the "Dawn of the North Star" launch mission involved a total of four people, including United States billionaire Isaac Man.
Isaacman and SpaceX's engineer Gilis took turns conducting spacewalks.
Neither of these two are professional astronauts, Isaacman is the initiator of "Dawn of the North Star" and the main funder of this project.
As for Gillis, he is a good friend of Isaacman, although Isaacman is not a professional, but he still has a lot of experience in space, because as early as three years ago, Isaacman had entered space on Musk's spacecraft!
Speaking of the "Dawn of the Polaris" mission, although it is nominally a commercial spacewalk, in fact the two did not "walk".
So what's going on here?
2. Commercial spacewalks, not real spacewalks
Because they just poked their bodies out of the hatch and their bodies remained in the cabin, in short, Isaacman and Gillis only felt a little bit of a spacewalk, which was a completely different concept from a spacewalk performed by a professional astronaut.
For example, spacewalks on the space station are generally carried out with tasks, so their spacewalks belong to work, mainly repairs and replacement of parts, and generally speaking, this kind of work lasts for more than ten hours at a time.
The reason why commercial spacewalks are so "easy" is that this time Isaacman and Gillis are wearing spacesuits that don't allow them to stay outside the capsule for too long. From the video footage, we can clearly see that this time the astronauts are wearing spacesuits that are particularly close-fitting, because the spacesuit is not equipped with a life support system.
The oxygen, power and even communication that the astronauts need are provided by an umbilical cable, in other words, even if the astronaut wants to walk a little farther, the umbilical cable length does not support it.
Although Isaacman and Gillis have undergone a series of professional training on land, their abilities are still far behind those of professional astronauts. It's not just a technical gap, it's also a psychological gap, knowing that inside and outside the cabin are two very different sensations.
Once this layer of protection is lost, when the astronaut faces the darkness of the universe, fear will arise in the bottom of people's hearts. This fear can be overcome, but it cannot be stopped, so this is the time to test the astronauts' psychological endurance.
3. The true purpose of "Dawn of the North Star".
For the media, the focus is on the first human spacewalk, but in fact, the Dawn of the North Star mission has another purpose!
It turned out that this commercial spacewalk was to test the performance of this spacesuit, and with the rapid development of space technology, modern spacesuits are also improving. In the past, the bloated spacesuit will slowly "slim down", and its function will decrease a little, but it will be strengthened!
For example, the spacesuit worn by Isaacman has several small designs, such as a camera installed on the spacesuit, as a commercial spacesuit, the camera is a big selling point.
After all, the spacewalk experience is only for a while, and if you want to reminisce later, you have to watch the video, so the high-definition camera is very necessary. Of course, this spacesuit is not the final version, because an EVA spacesuit must have a complete life support system, as well as strong protection functions.
The life support here includes oxygen supply, pressure stabilization and temperature regulation, as for the protection is mainly against cosmic radiation, of course, the spacesuit must also have the function of preventing space debris, after all, the power of a fragment the size of a grain of rice in space is comparable to that of a bullet.
You must know that this spacesuit will carry out manned lunar and manned missions in the future, so Musk's space dream is coming true little by little!
4. Black technology on the new EVA spacesuit
For a spacesuit that focuses on the future, there is no black technology that cannot be justified, for example, the spacesuit worn by this commercial spacewalk, the technology on it has a sense of futurism.
For example, the display on the helmet of the spacesuit is somewhat similar to the scene in the movie, and the human data collected by the spacesuit and the external data will be transmitted to the helmet in real time, so that the astronauts can make correct judgments through this information.
In addition, the EVA spacesuit has also been optimized for joints, the old spacesuit is not only bloated, but also inconvenient, and Musk's spacesuit has perfectly solved these problems.
In addition, thanks to the application of new materials, the protective function of the EVA spacesuit has also been strengthened.
5. The International Space Station sets a world record for the number of people in near-Earth orbit in space
Because of this commercial spacewalk, 4 people also went to the International Space Station, so the International Space Station also achieved a new achievement, setting a world record for the number of people in near-Earth orbit in space.
Polaris Dawn is scheduled to stay for five days, and after five days, four astronauts will return to Earth, after all, the Dragon spacecraft has an even more important mission to take the other two astronauts home.
With the failure of Boeing's manned space mission, and with SpaceX completing the first commercial spacewalk, the competition between the two space companies has become clear.
Obviously, the advantage of Musk's SpaceX is already very large, and if nothing else, NASA's space launch missions will be handed over to SpaceX in the next few years.
In addition, Musk's commercial space activities are also in full swing, and now it seems that commercial spacewalks are not too difficult.
In the coming years, there will be no shortage of such space business activities, and for Musk, these can only be considered appetizers, because the real feast is on Mars.
Musk has shared his Mars plan with everyone in public more than once, in this huge plan, the unmanned spacecraft will arrive on Mars first, and when everything is mature, it will be the first human landing on Mars.
According to Musk's plan, an unmanned starship will be launched in two years, and by 2028, the manned Mars flight program will be implemented. It has to be said that Musk's plan is crazier than the other, if a commercial spacewalk is a space mission based on commercial considerations, then the Mars plan is a suicide under the business model.
The cost of a spacewalk is high, but at least it is safe, but going to Mars is not a matter of how much money, and astronauts are facing a death journey with no return!
