html On the 110th, scientists released the first photo of human black holes, once again proving the hypothesis of general relativity proposed by Einstein more than a hundred years ago. Scientists say:
"We have seen what we thought was unseeable."
Humans have seen black holes that are impossible to see, what else is impossible? Time and space travel, immigration Mars , interstellar travel, the things depicted in science fiction novels seem to be one step closer to us.
While excited, you still need to understand that the actual development of human technology is far from that level. We don't know anything about real space travel and life.
Today, let’s read the three space station service experiences by former NASA astronaut Terry Virts and many stunning photos he took while working in space - "View From Above: An Astronaut Photographs the World).
Wilz is an extremely lucky person, and his space dream began in his childhood. Because of his good innate conditions and acquired persistence and hard work, he realized his childhood dream, which is rare in the entire human race.
Astronaut Terry Virts (Terry Virts)
Born in 1968, the picture book "Apollo Moon Plan" he read in kindergarten was the first book he read in his life. The book was full of moon, rockets, spacecraft, space suit and other lunar landing equipment.
Little Wilz was completely fascinated by the story of Apollo landing on the moon. He had the greatest wish in his life: to become an astronaut.
-year-old Wiltz took a photo with the aircraft 989 after graduating from US Air Force Academy , he obtained a master's degree in aviation science from Embrede Aeronautics University , and later became a US Air Force fighter pilot. During his service around the world, he flew more than 40 aircraft models and had a cumulative flight of more than 5,300 hours. Wilz is the kind of person who feels more comfortable flying at high altitude than moving on the ground.

years after serving in the U.S. Air Force, in July 2000, Wilz was selected as the 18th NASA team astronaut and began several years of space training.However, everything is not smooth sailing. It took Wilz a decade from being selected to perform his first mission.
Finally in 2010, he was appointed as the pilot of the space shuttle "Entertainment" to carry out a 13-day mission to send two new compartments to the US space station.
boarded the "Entertainment"
"Entertainment" space shuttle launch
two years after the mission ended, Terry received another two and a half years of training to prepare for the long-term international space station : practice spacewalk and run-in with the new crew members.
In 2014, Werz and two other astronauts boarded Russia's Soyuz TMA-15M carrier rocket and embarked on a journey to the International Space Station. It took a total of 200 days and was the third consecutive space mission NASA has carried out.
International Space Station full set of equipment
International Space Station flies at a speed of 28,000 kilometers per hour, orbiting the earth for 16 times a day.
means that in 200 days, Wilz flew a total of 13.518 million kilometers, orbited the earth 3,184 times, and performed hundreds of scientific experiments and three space walks.
In addition, the photo shooter Wiltz took 319,000 photos in 200 days, and is currently the person who takes the most photos in space.

In order to share these photos with people on earth, he was authorized to apply for Twitter and Instagram accounts, becoming an internet celebrity astronaut who shares the wonders of space. This is why this exquisite book is created.
The beauty of the Algerian
Since the first time flying the space shuttle , Werz has recorded in detail what he saw, heard, thought and felt during his three missions.
His excitement, tension, worry, excitement, dissatisfaction, and exhaustion, these emotions and details of life have turned the astronauts far away in outer space into flesh and blood bodies so close to us, no longer like the out-of-reach superheroes created in science fiction movies.
Flying
I had never seen that shade of blue before. It was as if I had been raised in a black-and-white world and I was seeing color for the first time, reminding me of the first time I saw my daughter’s blue eyes.
That was like a person who had been living in a black-and-white world. The first time I saw color, which reminded me of the first time I saw my daughter’s blue eyes.
That was the feeling of my daughter’s blue eyes.
This was my very first sunrise from space, flying over the Alps, and although I had seen thousands of astronaut photos of the Earth, nothing could have prepared me for this experience.

I was prepared me for this experience.
This was my very first sunrise from space, flying over the Alps, and although I had seen thousands of astronaut photos of the Earth, nothing could have prepared me for this experience.
I happened to be over the Alps when I first saw sunrise in space. Although I have seen the Earth photographed by astronauts countless times, it is far less than this scene that is deeply shocking.
The blue of our atmosphere was so intense that I could barely look away—until I noticed the Alps whizzing by underneath.
I was attracted by the dazzling blue atmosphere and could hardly divert my sight until I realized that the Alps were flying by underneath the spacecraft.
I was piloting the space shuttle Endeavour, still climbing into orbit. We hadn’t yet performed the “OMS-2” rocket burn, so as I looked out of my pilot’s window and saw the Alps fly by, it was the closest daylight view of Earth that I would ever have on either of my two spaceflights. And it was amazing.
The space shuttle I was flying was climbing into flight orbit, and the rocket's OMS-2 had not yet been ignited, so I took the opportunity to see the Alps flashing through the window. This was also the closest time the Alps were me during the day during the two space flights. It's really incredible!
Peaks were passing by every few seconds—mountain ranges that would take hours to drive across were literally whizzing by, one after the other, as we flew at 17,500 miles an hour. The mountains on Earth flashed one by one, and the mountains that usually took several hours to cross were now quickly disappearing from their sight.
I thought of the years that I lived in Germany and France and took long vacations driving through those very valleys, and now I could see them in their entirety.
I remember during the years I lived in Germany and France, I would drive through villages and towns during the long holidays, and now I could see these beautiful scenery.
Then, in only a minute or two, the Alps had become the Balkans and it was time to get back to work. We had a space shuttle to fly.
After just one or two minutes, the Alps had become the Balkans and it was time to get back to work. We had a space shuttle to fly.

Destination: International Space Station.
The destination of this voyage: International Space Station.
What is the experience of working in weightless situations
As the astronauts often say: "It is more difficult to do anything in a weightless environment." Everything is floating! Nothing can stay in the same place properly! Too annoying!
In order to fix items, we use a lot of Velcro, tethers, sealing pockets, pockets and even occasionally use strong tape, but sometimes even tape rolls will float away.
The most difficult thing in a weightless environment is how to correctly control the direction of the body, that is, how to start from a place a and finally reach the destination place b.
Weight loss
One key point is that lets the thrust pass through the center of gravity of your body ; but if the ends of the arms and legs are too strong, you will turn a few more circles. Any force exerted from a part away from the center of gravity will trigger the body's rotation.If you can use force correctly, it will be relatively easy to reach the destination.
But I find that I often still spin after arriving at my destination. At the beginning of my first space journey, I found that I always had to go one or two more turns than I expected. If I were to push myself to a farther position and couldn't catch something that could correct the direction on the way, I might reach the destination with my body spinning and rushing my back, so I had to pretend to do it on purpose (hopefully not captured by a nearby camera and sent back to the ground control center).
What color is the earth in outer space during the day?
is mainly white and blue.
China Xinjiang Mountains
When I sailed during the day for the first time, the beautiful scenery of the universe made me intoxicated.
I clearly see through the sunshine that a color occupies the whole world: white.
Europe, Russia, Siberia and other regions are covered in white, especially in winter.
Papua New Guinea
White not only appears in a corner of the mainland or a specific area, but continues to extend along the ground plane, as if bypassing half of the earth, from European plains in the west to Kamchatka Peninsula in the east.
The area of white land is so large that it surprised me. It may be that endless snow dyed more than 1,000 miles (1,000 miles = 1,609 kilometers) of land into pure white.
Greece Island
Two hundred days of space life, what should I do during the holidays?
In space, we celebrate Thanksgiving, Christmas, New Year, Easter , and of course the opening day of the baseball game and the Super Bowl game.
Christmas
In the International Space Station, we also celebrated our birthdays for each crew member, and we did not miss International Women's Day and International Labor Day. It can be said that we have put a lot of effort into being able to have a party in space.
What about food?
All foods must be prepared and packaged a few months ago, which greatly limits the types of foods that can be brought into space. For example, we can't bring bread because it can't be saved for a long time, and tortilla is its replacement. In fact, some astronauts will really eat tortillas for every meal.
Fresh oranges from Earth
There are actually a variety of foods in the space station, some of which are "commercial spot" such as bagged tuna , beef jerky, and MM chocolate beans; and some are dehydrated foods, which are what most people think of as aerospace foods. Meat and vegetables are dehydrated and enclosed in vacuum plastic bags.
We put these bags in a machine containing cold or hot water, and the machine will mash them and shake them, which only takes 10 minutes - look! A meal in a bag is finished!
In addition, there are ready-to-eat foods in green metal bags, similar to soldiers' military rations. All kinds of meat, vegetables and desserts are packaged in this form.
European Space Agency is packing out outer space supplies
We use a briefcase-sized "electric stove" to heat food - that's my way of cooking.
But there are also traditional Thanksgiving foods: smoked turkey, tortilla filling, tortillas, candied yam , mashed potatoes, all kinds of tea and coffee, and blueberry cherry pastry.
Can astronauts see black holes?
cannot.
Unfortunately, in the vast universe, a small orbital spacecraft is no closer to those celestial bodies than we are on Earth.
However, we can see it more clearly because the atmosphere does not obstruct our field of view. But we still have to pass through several thick glass windows, several of which are also coated with scratch-resistant coatings.
Wilz
, located in the dome bin, What's worse is that these glass completely destroy the chance of taking clear zoom photos, and the daytime view is always covered with spots formed by the reflection of the sun.
What can humans produce on the International Space Station at present?
Today, space life depends entirely on the earth's supply, such as water, food, oxygen , clothing, etc. We produce nothing in space except electricity (thanks to the huge solar cell pack ).
If humans really want to immigrate to other planets, it will indeed change, but for now, it is all pretty good.

What is the most expensive express delivery in the world?
from the Earth to the International Space Station, $20,000 per kilogram.

Will aliens discover humans when passing through the earth during the day?
is very likely to not be discovered, because the aliens in a hurry must stop and observe carefully to see the metropolis on Earth. Even when there are no clouds, aliens are very likely to ignore the reinforced concrete forests.

0What emergency situations will astronauts encounter in the space station? The concentration of carbon dioxide in the cabin of
increases, the condensed water in the helmet is released in the air-tight cabin, causing suffocation, the supply spacecraft failed to launch, the supply spacecraft cannot dock with the space station after entering space, and the most terrible deadly gas ammonia leak.
working outside the capsule
ammonia gas is used as a coolant for the external trusses of the International Space Station due to its excellent chemical properties. But the designers of the space station must do their best to make sure it never enters the cabin, thus mixing into the gas that the astronauts breathe. I learned during training that once a person smells ammonia, it is too late.
1What happened to the astronauts in the space station surprised you?
collects garbage. Because things are transported to the space station, they are packed like Russian dolls , resulting in huge amounts of garbage.
2What is the mood when walking in space?
Before taking the first step, he could only describe his mood at that time as "uneasy".
You can't predict what will happen when you step into the dark universe, when you will be separated from the vacuum environment by a layer of plastic a few millimeters thick.
I have always been a peaceful and steady person. Even when I encounter an emergency when I am a fighter pilot and a pilot, I can deal with it calmly. But in fact, I couldn't be sure of my reaction before I actually left the cabin.
Some astronauts feel strongly dizzy at first because when they walk from a relatively stable space station into infinite outer space, they see the floating earth in the distance.
Space Walking
I am very lucky because when I took the first step, the sun had not risen, and the earth was shrouded in the night. I couldn't see the surface of the earth clearly, so I couldn't say that I felt falling or dizzy.
If you feel that you are moving slowly, it may actually be that you are walking too fast. Because the universe has no friction and only needs a little force to move, it is actually easy to increase the speed, but it is very difficult to stop.
3In addition to the breathtaking beauty, what else does Wilz see?
At night, when Wirtz was watching the earth, he found that the Nile Valley region in northern Africa was 8,000 kilometers apart from Johannesburg in the south. More than 1 billion people live in the area between the two places, but most areas have almost no lights at night.
Apart from thunderstorms, the night on the African continent is almost pitch black, and only a few small cities occasionally flash a little light or flames burning oil products.
At dawn North Africa Duns on the land
This is incredible, and the population living on this vast land is twice that of Europe. At the root of this, this not only shows that Africa lacks light at night, but also shows that they lack communication, lack of refrigerated food, no ventilation system to prevent mosquito bites, and even rarely participate in global economy . The quality of life of residents is far behind that of other parts of the world.
Round farmland in Tabuk Province, Saudi Arabia
Interestingly, some cities are just the opposite. The brightness of a city exceeds the upper limit of the light brightness corresponding to the number of urban population.
Arabian Peninsula belongs to this kind of cities such as Mecca , Riyadh , Jeddah , and Jeddah are very bright at night.
Persian Gulf overlooking
Western Europe and the eastern United States region lit up in flakes of light at night, and the "per capita lighting" here is higher than other parts of the world. "The amount of lighting per capita" is a symbol of wealth that I can see in space.
Wilz's favorite Panama
In space, I clearly see that the soil on Madagascar (the most abundant region in the world) is terrible: there is a large patch on the west side of the island that seems to be grassy, and orange-red silt flows into the sea in large quantities, a lot of the soil comes from the Bezibuca River Delta. These are evidence of deforestation, and most of the forests were cut down 50 years ago, but the impact is still obvious today.
When such large-scale destruction can even be seen from space, things are not great.
4What is the most touching thing about Wilz’s story?
Science has no borders.
computer issued an ammonia leak alarm, American astronauts closed the US cabin and went to the Russian cabin to wait for Houston's investigation results. If it was really an ammonia leak, the US cabin would have to be permanently closed.
On Earth, the United States-led West imposes sanctions on Russia because of the Crimea issue. But the Russian deputy prime minister called and said: How long does American astronauts want to stay?
5What is the most exciting part of space travel?
returns to Earth on the combat nation's spacecraft "Soviet".
Wilz returned to Earth the previous time he was riding a space shuttle produced by the United States. After entering the atmosphere, the space shuttle can fly softly like a passenger plane, and the whole process is relatively comfortable. However, the "Soviet" spacecraft is different: fast speed, bumpy, loud noise, uncertain direction when landing, and strong impact.
"Soviet" soft landing
According to experts' requirements, in order to prevent poor standing endurance and dizziness, astronauts drank a lot of liquid before taking off.
"Soviet" is very small. After entering the seat, the astronauts fastened their seat belts, hugged their knees in front of their chests, and shrank their bodies into a ball. The three astronauts squeezed together.
Three astronauts squeezed into the narrow "Soviet" cabin
returned to the atmosphere. When freely fell , slowdown parachute suddenly opened. Everyone who has been sitting on jumping machine knows the feeling of dying. Three astronauts screamed and laughed.
There is an astronaut named Scott Kelly called experiencing a "roller" again, and he signed another one-year mission.
Moreover, Werz said that the "soft landing" on the Kazakhstan grassland should also be renamed "flying landing slightly stronger than the scene of a car accident". Anyone who has sat on Russian Airlines knows that the mood was very complicated when applauding in the end.

6How did space travel change people's worldview and outlook on life?
No question about it: Space travel changes your perspective.
There is no doubt that space travel will change your worldview.
A few hours after my first mission, returning to Earth on the space shuttle Endeavour, I had completed all of my postflight medical tests, met with NASA management, and reunited with my family. Finally, I was alone in my room in astronaut crew quarters at the Kennedy Space Center, exhausted and ready for bed.
A few hours after I returned to Earth on the Endeavour shuttle, I completed all my medical examinations, met with NASA's management, met my family I missed day and night, and finally, exhausted, I returned to the astronaut dormitory of the Kennedy Space Center alone, planning to go to bed.
And I did what anyone does when they return to their hotel room on a business trip: I flipped on the TV. The standard fare of cable television news started up: Such and such had happened, people were shocked, blah blah blah. Sports scores. Silly commercials.
I turned on what anyone does when they return to their hotel room on a business trip: I flipped on the TV. The standard far of cable television news started up: Such and such had happened, people were shocked, blah blah. Sports scores. Silly commercials.

I turned on what anyone did when they return to their hotel room on a business trip: I flip The standard package for cable news jumped out: something happened one way or another, people were shocked, it was like this, it was like this; it was all kinds of sports events; and there were commercial advertisements all over the sky.
It didn’t take more than a minute before I had to turn it off. It felt like my body was rejecting all this input, just as it would reject an organ donation that had the wrong blood type. All of this noise was just completely foreign to who I was—or, more appropriately, who I had become.
. I feel like my body is resisting the input of this information, like rejecting organ transplants from different blood types. All this "noise" means nothing to me as a person—or, more appropriately, for astronauts who have just returned from space.
A few hours before, I had been orbiting Earth, seeing our planet from space, flying the most amazing machine ever built by human hands, working with a team that was the absolute pinnacle of humanity. And now here in my room I was watching what was being sold as news—and with my newfound perspective, I just could not stomach it. My worldview was changed forever in a prominent way.
A few hours ago, I was still flying around the earth, observing our planet from space, riding on the most magical machines we humans have made, and working together is the best team of humans. But at the moment, I am watching news made like merchandise in the room - for me now, such a show is boring at all. I realized that my worldview has changed forever and has become more profound.
The biggest change by far—and the one for which I will always be most grateful—is this big-picture perspective. That will stick with me for the rest of my life.
Thinking about problems is more conscious of the overall situation. This is the biggest change I have so far and the change that I am most grateful for. It will accompany me for the rest of my life.
Thinking about problems is more conscious of the overall situation. This is the biggest change I have so far, and it is the change that I am most grateful for the most. It will accompany me for the rest of my life.
Whenever I feel the pressures of modern life, stress about minutiae, or worry about the future, I remember my time in the space station. Back to seeing the sun set, hearing God speak to me during the EVA. Or watching our galaxy rise on the horizon. Or seeing a sea of lightning flash a hundred times a second. Or simply back to floating weightlessly.
Whenever I feel the pressure from modern life, as well as the anxiety about all kinds of trivial matters, and the concern for the future, I will think of those days on the space station: when I watch the sunset in space, I hear the secret words of God; when I see our planet rising from the horizon; when I see lightning flashing hundreds of times every second, like a sea of light; or just think of the feeling of floating in a weightless environment.
Dawn
When I’m there in my mind and realize how many billions of these beautiful sunsets there have been and will be in the future, the cares of the world just don’t seem that pressing.

When I realize that billions of beautiful sunsets have existed, and that the future will continue, the pressure of the real world is less important.
It really brings home the words from the book of Matthew: "Do not worry about tomorrow, for tomorrow will worry about itself." Living daily life down here on the planet is so much better with this attitude!
This sentence in Matthew is deeply rooted in my heart: "Do not worry about tomorrow, because tomorrow will worry about tomorrow." With this attitude, daily life on earth feels much better.
Maybe space travel will no longer be so expensive in decades, maybe we can fly out of the atmosphere to outer space and live in an international space hotel. The two-day and three-night itinerary covers: space starry dinner, enjoying the beautiful scenery of the earth (day + night), space walking, taking photos, calling family, etc.
So, just like Liu Cixin, let’s work out, refer to Wilz’s records and start preparing for such an adventure!

The top 3 readers who have received the most likes
will each receive a book called "Long Farewell".
Deadline: April 15th 11:00
The book I want to recommend today is also the book of life that Haruki Murakami strongly recommends! Since middle school, Haruki Murakami has been in trouble, and he has read the novel more than a dozen times, and has translated and introduced it to Japan himself. This book is Raymond Chandler's "Long Farewell".
"Long Farewell" and Fitzgerald "The Great Gatsby", Hemingway "The Sun Rises As Always", and Kerouac "On the Road" are ranked as the four masterpieces in the golden age of American literature!
At the same time, this is also a novel that "there is a manly flavor between the lines", a masterpiece with its own intoxication! If you like cool men and speak cool lines in a cool tone in a cool environment, then you must not miss "Long Farewell"!
