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.
I think the question is, are there women and have there been women who want to do science and could be doing great science, but they never really got the opportunity?
From the point of view of basic physics, the most interesting phenomena are, of course, in the new places, the places where the rules do not work - not the places where they do work! That is the way in which we discover new rules.
... that, in a few years, all great physical constants will have been approximately estimated, and that the only occupation which will be left to men of science will be to carry these measurements to another place of decimals.
One day I went up to my mom and I said, 'Mom, can I have permission to build a 2.3-million electron-volt atom smasher - a betatron - in the garage?' And my mom stared at me, and she said, 'Sure. Why not? And don't forget to take out the garbage.'
I think we need to move to the moons of Mars and learn how to control robots that are on the surface. It's not the impatient way of getting there, but Mars has been there a long time.
Science is the greatest of all adventure stories, one that's been unfolding for thousands of years as we have sought to understand ourselves and our surroundings.
