Those who are lucky to see the earth from the universe, what do they think?

We live in an age where people can admire their common home from space. During the history of tens of thousands of years, it was unbelievable.

The Italian astronaut holds the record for the second longest time of an uninterrupted flight. She spent 199 days on the International Space Station in 2015. (NASA broke this record with 289 days in space in 2017).

The longer I stay on the trajectory, the more I become aware of human development on Earth, Cristoforetti said. As the small giant geologic plates had just reached the eye, below that skyscrapers ceaselessly sprung up beside ancient buildings hundreds of thousands of years ago. At night, what people have built glows and glitters when viewed from above.

'The whole planet is below you, a lot of things you can see without doing anything but just watching it for a whole day. From above, we cannot see people, we see that humans are extremely small compared to the immense planet. Suddenly blinking, I realized that if humanity does not unite to grow together, it will disappear quickly like a blink of an eye. "

Bound by gravity and body structure, humans cannot easily fly out of this planet to see it. For most people, leaving the Earth is an impossible thing. During the six decades since the era of space began, only a few people could see sunlight shining right after the Earth's atmospheric curve. From 1961 until now, only 556 people have seen this.

Less than, with 24 people, that's the people who are watching the Earth slowly smaller and smaller and smaller enough to fit into the watch. They flew to the Moon, the Earth's natural satellite. Less than that, only 6 people flew to the other side of the Moon and left behind the brilliant blue globe.

In 2009, NASA astronaut Mike Massimino approached the Hubble Space Telescope, which was 568 km above the surface, performing the task of repairing the human eye for the last time. The super sensitive eye - Hubble glasses - kept looking at the deep space, while Massimino looked towards the Earth and quickly fell in love with it.

The lush tropical rainforest forests of South America, seemingly endless golden sand mats in Africa, the urban lights glistening beneath like night stars, this planet is nothing more than a celestial sugar when viewed from this height.

'At the time, I thought that the heaven after death was when the souls of humans flew so high and saw the planet that they had lived from above. I was still living in a paradise but did not recognize. The moment I watched this world from above, I realized my daily life as angels playing in paradise. It's fortunate to be born on this planet. '

Humans were unable to change the body structure to conquer the universe, but developed a marvelous technology: space exploration. But don't be in a hurry to blame such human biological constructs, aren't we taking the downside as a springboard for technology development?

From the first people living in this world, until astronauts with luck flying into space, we have not yet developed the words used to describe the beauty of the planet Earth when seen from space. That is also the reason why space astronauts find it difficult to be asked to describe the scene that they see.

Italian engineer and astronaut Luca Parmitano, said that language was developed to convey the meaning of the speaker. It was not until the middle of the 20th century that people had no need to express the pristine beauty of the Earth when lying in the middle of the harsh universe.

Astronaut Karen Nyberg.

In September 2013, on his second flight to the International Space Station, Nyberg took the time and made a stuffed dinosaur for his 3-year-old son in space. It was the first toy created in the universe, made of materials that could be found in every compartment on the station.

Meticulously crafted to help her feel close to her family living below. Through the cotton dinosaur, the astronaut also wanted to express her views on the negative change of the natural ecosystem at the time before and after she came to Earth orbit.

'In the future, I will probably become a participant in animal conservation movements. Each part of this Earth lives and reacts to another. When I saw this planet from above, I realized this and hoped to help each group of wild animals have a chance to live. If I could do that in just one spin around the Earth's axis, this planet would become a better place for everything to live together. "

Flying into space and watching the Earth really changed a person's perspective. American astronaut Nicole Stott has had two missions on the Space Shuttle Discovery and returned to the art creation capabilities at a point of view that no one could have. Canadian astronaut Chris Hadfield clearly felt his love for his fellow men when he looked at the Earth every day.

Kathy Sullivan, the first American woman to take steps in space in 1984, returned to her motherland with a desire to do community-connected projects.'Look at the Earth from space not only to satisfy your curiosity, take a couple of photos of documents. Through that trip, in my heart, I really rose up the desire to make the society around me become better " .

Astronaut Gennady Padalka.

As a Russian astronaut who holds the record in the longest space, with 878 days accumulated from 1998 until 2015. For him, the teamwork experience is the most valuable thing he has learned. When you have to live in an environment, you can die at any time by countless dangerous things in the universe.

'So, how can our planet be helpless in such a cold space? Through the flights, I was aware that I would treat my mother with nature better, she took on the billions of children who still face day and night risks from the universe. '

Astronaut Ed Lu.

A veteran who participated in three NASA space flights from 1997 to 2003, Lu had a great view of the impact craters on Earth, which were places from the bombardment. man by external meteorite billions of years ago.

In 2002, he co-founded the B612 Foundation, a non-profit organization that works for a very macroscopic purpose, calling himself an organization that "works on the largest technical scale that is hard to imagine." out. ' The sole purpose of the fund, which is to prevent any effects of asteroids affecting the Earth.

'The biggest impression I get when contemplating the Earth is the intense life that always rekindles and booms strongly in it. God may have repeatedly tried to destroy all life here, but somehow I and you guys can survive until now to look back on the Earth's glorious past. ' .

After retiring from work at NASA, Sullivan held leadership positions in the US National Oceanic and Atmospheric Administration (NOAA) for three years. Now, she used the cameras of artificial satellites orbiting the Earth every day as her eyes to watch the beloved planet. 'This planet, when viewed from above, is very charming, I keep looking and not getting bored. Perhaps the love of a man is easier to give up than watching the Earth from above. '

When the world falls into the darkest times, only a picture of the Earth from above also makes millions feel happy and change their view of the surrounding life. In 1968, the Apollo 8 crew became the first people to fly farther away from Earth and circle the other side of the Moon.

Christmas Eve that year, astronaut William Anders captured a legendary image and in the minds of millions of people still remains indelible: a green world sprouting from the horizon of a dry place grim death. Now, we call that picture 'Earthshine', the image has raised the awareness of many people in preserving the planet's beauty and fragility.

2018 is the 50th anniversary of this iconic image that was released and became the most used image in the environmental protection movements of the time. To celebrate in a solemn way, the American astronaut Leland Melvin started a public health project, taking the astronaut's diet, exercise and nutrition and recommending everyone to done to get a healthier lifestyle.

Having attended the Detroit Lions team in the American Football League in 1986, a serious injury put an end to his sporting career. But when life closes a door, it opens another door for us.

Melvin turned to another direction in his life: flying into orbit. During NASA's two flights as an astronaut in 2008 and 2009, he saw firsthand the spectacle of Earth's ocean from above. Their colors are extremely diverse, they spread evenly across different green shades. The desire to explore the world around him always inspires him to open an educational organization for children, he wishes to spread the spirit of learning to the younger generation.

Obviously, wanting to protect this planet is the common desire of those who have flown away from it. Russian astronaut Gennady Padalka has more hours in space than anyone else (if calculated by the number of hours accumulated through many single flights). During his 28-year career, he flew into the unknown space many times, but there was something stronger than gravity, holding him back to his motherland.

'It is the connecting force, the connection between each person and mother nature. Earth is the only planet to have life in our knowledge. Over the past decade we have found countless planets that roam the Milky Way, but none of them exist as human beings like us. For these reasons, how can I leave this dear land? '

No matter how high it is, seeing how big the Earth is, astronauts still yearn to serve and develop this world on the ground. Because, nowhere else is my home.
