Last Updated: August 17, 2022 by Team

Are you looking for inspirational space quotes and meaningful sayings? Here you’ll find an incredible selection of quotes and deep thoughts from the world’s top thinkers and celebrities.

Humans have been wondering about space for centuries, but we have only been able to visit space with the advancement of science in the last century. Space is a giant leap for humankind.

On July 20th, 1969, Apollo 11 landed on the moon. Astronauts Neil Armstrong, Buzz Aldrin, and Michael Collins operated the Saturn V rocket, departing the Kennedy Space Center at 9:32 a.m EDT and landing the moon module (the Eagle) at 4:18 p.m EDT.

With over half a billion people watching live on television, Neil Armstrong climbed the ladder and proclaimed: “That’s one small step for a man, one giant leap for mankind.”

Aldrin joined him shortly afterward, offering the people at home a simple but powerful description of the moon’s surface: “magnificent desolation.” The astronauts explored the lunar surface for two and a half hours, taking photos and collecting samples.

Before heading back to Earth, the crew left behind an American flag, a patch honoring the fallen crew of Apollo 1, and a plaque on one of the Eagle’s legs. It reads, “Here men from the planet Earth first set foot upon the moon. July 1969 A.D. We came in peace for all humanity.”

We’ve handpicked each of the space quotes below and added my favorite famous astronaut quotes and quotes about space exploration from the world’s best novelists, teachers, engineers, actors, science communicators, screenwriters, entrepreneurs, and inspirational speakers.

Final Thoughts

We are in many ways unimaginably small within this universe, yet uniquely special. We have the power to go to space, are self aware, and masters of our own destiny. Yet we are on a small planet circling a very average star, spiraling around a massive galaxy of hundreds of billions of stars. That galaxy, on top of that, is just one of billions of galaxies. Yet we are alive today, and that is a gift no one can undervalue.
