Seeing Eаrth frоm Spаce [A] Fоr the bulk оf humаn history, it's been impossible to see Earth in terms of its place in the universe. Bound by gravity and biology, we can't easily step outside it, above it, or away from it. For most of us, Earth is larger than life. Even now, after nearly six decades of human spaceflight, precious few people have rocketed into orbit and seen the sun emerging from behind that curved horizon. Since 1961, a mere 556 people have had this rare experience. Fewer, just 24, have watched Earth shrink in the distance, growing smaller and smaller until it was the size of the face of a watch. And only six have been completely alone behind the far side of the moon, cut off from a view of our planet as they sailed in an endlessly deep sea of stars. [B] It's an essentially unnatural thing, spaceflight. After all, our bodies evolved specifically to succeed on this planet, not above it. Perhaps that's why it can be difficult for astronauts to describe the experience of seeing Earth from space. [C] Italian space traveler Luca Parmitano says that we haven't yet developed the words to truly convey the realities of spaceflight. The building blocks of modern human communication, words are necessarily limited, no matter which language you choose (Parmitano speaks five). And until the mid-20th century, there was no need to express what it means to see our planet in space. "We just don't think in terms of spaceflight," he says. [D] Seeing Earth from space can change the way a person sees the world. U.S. astronaut Nicole Stott flew twice on the space shuttle1 Discovery and returned with a new drive for creating artwork depicting the view. Canadian astronaut Chris Hadfield says that while orbiting Earth, he felt more connected to the people on the planet than ever before. [E] Kathy Sullivan, who in 1984 became the first American woman to perform a spacewalk, returned with a deep awe for the complex systems that come together to make Earth an improbable home for life. "The thing that grew in me over these flights was a real motivation and desire...to not just enjoy these sights and take these pictures," she says, "but to make it matter." After retiring from NASA, Sullivan led the National Oceanic and Atmospheric Administration for three years, using the robotic eyes of orbiting satellites to follow her passion. She says Earth from above is so beautiful, she never grew bored looking at it. "I'm not sure I'd want to be in the same room with someone who could get tired of that." [F] Even when words fail us, a single picture of home from above can change the perspectives of millions of people. In 1968, the Apollo 8 crew became the first people to rocket far away from Earth and loop around the moon. On Christmas Eve, astronaut William Anders took what would become an unforgettable image: a lush2 world rising above the lifeless, cratered lunar3 horizon. Now called "Earthrise," the photograph boosted awareness of our planet's beauty and fragility. [G] "Twenty eighteen is the 50-year anniversary of that iconic4 picture that helped define the environmental movement. What are the course corrections we need to do now that will help us get to the hundredth anniversary?" asks U.S. astronaut Leland Melvin. He's working with a group of fellow space travelers to rethink how we balance ecological health and human needs. The project will use astronauts' experiences to help others adopt more sustainable lifestyles. [H] Clearly, a desire to protect the planet is common among those who have left it. Russian Gennady Padalka has logged more total days in space than anyone else. The attraction of spaceflight kept him on the job for 28 years, but something even more powerful than gravity kept bringing him home. [I] "We are genetically connected to this planet," he says. And to the best of our knowledge, Earth is unique in its ability to support life as we know it. The past decade or research has shown us that we are one among billions of worlds in space, but this strange rock is the only one in reach that's just right for humans. [J] As astronaut Mike Massimino said, "I thought at one point, if you could be up in heaven, this is how you would see the planet. And then I said, no, it's more beautiful than that. This is what heaven must look like. I think of our planet as a paradise. We are very lucky to be here." [K] There really is no place like home. How does the author characterize the impact of seeing Earth from space on individuals?
