The ride to orbit was impressive, as it always is. But once I got on board the space station, it really felt like I was visiting an old home; it felt very comfortable.

During my time in orbit, I lost bone mass, my muscles atrophied, and my blood redistributed itself in my body, which strained my heart. Every day, I was exposed to ten times the radiation of a person on Earth, which will increase my risk of a fatal cancer for the rest of my life.
Interpretation
The quote reflects the physical challenges and risks astronauts face in space.
Scott Kelly's quote highlights the significant physical toll that space travel takes on the human body, illustrating the loss of bone mass, muscle atrophy, and increased radiation exposure that can lead to serious health risks. It underscores the sacrifices and dangers that come with exploration beyond our planet, reminding us of the delicate balance of health and the vast unknown of space.

If we're going to go farther from Earth, to Mars or somewhere else someday, we have to have a good understanding of the psychological impact on people. And not only psychologically, but how it affects their cognition. We're doing a lot of research on my cognitive abilities.
The problem of neurology is to understand man himself.
We fly to 106 kilometers. We've always had as our mission that we always wanted to fly above the Karman line because we didn't want there to be any asterisks next to your name about whether you're an astronaut or not.
We simply must balance our demand for energy with our rapidly shrinking resources. By acting now we can control our future instead of letting the future control us.
If we use our fuel to get our power, we are living on our capital and exhausting it rapidly. This method is barbarous and wantonly wasteful, and will have to be stopped in the interest of coming generations. The heat of the sun's rays represents an immense amount of energy vastly in excess of waterpower...The sun's energy controlled to create lakes and rivers for motive purposes and transformation of arid deserts into fertile land.
Nuclear power plants must be prepared to withstand everything from earthquakes to tsunamis, from fires to floods to acts of terrorism.
Through every rift of discovery some seeming anomaly drops out of the darkness, and falls, as a golden link into the great chain of order.
