What is outer space?
If asked, of course, we all know what outer space is and that it has always been there somewhere around the Earth for all this time, but the problem here is that space represents a challenging environment for human exploration because of the dual hazards of vacuum and radiation. Microgravity also has a negative effect on human physiology. In addition to these health and environmental issues, the economic cost of putting objects, including humans, into space is very high. So, there we have it.
Outer space, or just space, is the expanse that exists beyond the Earth and between celestial bodies and throughout our history, the humanity was curious about the secrets that lie within it and how it can be connected to our future.
Let’s find out, what do the greatest minds of all times think about it.
“Exploring and colonizing Mars can bring us new scientific understanding of climate change, of how planet-wide processes can make a warm and wet world into a barren landscape. By exploring and understanding Mars, we may gain key insights into the past and future of our own world.”
– Buzz Aldrin
“Earth as an ecosystem stands out in the all of the universe. There’s no place that we know about that can support life as we know it, not even our sister planet, Mars, where we might set up housekeeping someday, but at great effort and trouble we have to recreate the things we take for granted here.”
– Sylvia Earle
“Across the sea of space, the stars are other suns.”
– Carl Sagan, Cosmos
“By refocusing our space program on Mars for America’s future, we can restore the sense of wonder and adventure in space exploration that we knew in the summer of 1969. We won the moon race; now it’s time for us to live and work on Mars, first on its moons and then on its surface.”
– Buzz Aldrin
“The single simplest reason why human space flight is necessary is this, stated as plainly as possible: keeping all your breeding pairs in one place is a retarded way to run a species.”
– Warren Ellis, “Warren Ellis: On Space Travel”, Wired
“The venture into space is meaningless unless it coincides with a certain interior expansion, an ever-growing universe within, to correspond with the far flight of the galaxies our telescopes follow from without.”
– Loren Eiseley,
the Star Thrower
“I think humans will reach Mars, and I would like to see it happen in my lifetime.”
– Buzz Aldrin
“If there was an observer on Mars, they would probably be amazed that we have survived this long.”
– Noam Chomsky
“The purpose of going to Mars is for humans to first begin to occupy, permanently, another planet in the solar system. The astronauts or pilgrims, whatever you might call them, are going to be very historically unique human beings.”
– Buzz Aldrin
“I think space exploration is very important. I think there is very intelligent life on Mars. I believe that Martians are spying on us from the bottom of the ocean.”
– Annabella Sciorra
“Human exploration and colonization of Mars will keep us busy for hundreds, even thousands, of years. During that time, there will be advances in nanotechnology, space sailing, robotics, biomolecular engineering, and artificial intelligence. These advances are occurring even now, affecting our outlook about what it means to be human and engage in human activity. Those technologies will not merely allow us to stay home on Earth and Mars, but our minds will extend our presence throughout the universe so that we will not need or want to extend our bodies there — even if we could, which I think is doubtful.”
– Louis Friedman,
“Beyond Mars: The Distant Future of Space Exploration”,
“As long as we are a single-planet species, we are vulnerable to extinction by a planetwide catastrophe, natural or self-induced. Once we become a multiplanet species, our chances to live long and prosper will take a huge leap skyward.”
– David Grinspoon
“Only via continuing to probe every nook and cranny of the universe that is accessible to us will we truly build a useful appreciation of our own place in the cosmos.”
– Lawrence M. Krauss,
A Universe from Nothing
“Returning to Earth, that was the challenging part.”
– Buzz Aldrin,
“The Dark Side of the Moon“
“What is it that makes a man willing to sit up on top of an enormous Roman candle, such as a Redstone, Atlas, Titan or Saturn rocket, and wait for someone to light the fuse?”
– Tom Wolfe,
the Right Stuff
“NASA’s next urgent mission should be to send good poets into space so they can describe what it’s really like.”
– Shannon Hale,
“Man must at all costs overcome the Earth’s gravity and have, in reserve, the space at least of the Solar System. All kinds of danger wait for him on the Earth… . We have said a great deal about the advantages of migration into space, but not all can be said or even imagined.”
— Konstantin Tsiolkovsky,
The Aims of Astronautics, 1929.
“No matter how vast, how total, the failure of man here on earth, the work of man will be resumed elsewhere. War leaders talk of resuming operations on this front and that, but man’s front embraces the whole universe.”
— Henry Miller,
Sunday after the War, 1944.
