In other words, it encourages us to appreciate not only what we find, but also how we go about finding it.


"Space travel isn't just a technological achievement; it's also a cultural achievement, and it speaks to who we are as a species."

By venturing into the cosmos, we are transcending our earthly boundaries and pushing the limits of human knowledge and understanding.

"I think people have this idea of astronauts as superhuman, but we're not. We're just people who made a choice."

This reminder helps dismantle any potential idolization or unrealistic expectations surrounding the astronaut profession. It also serves as an inspiration for those considering space exploration careers, demonstrating that the choice to become an astronaut is within the reach of ordinary people with extraordinary determination.
