Planetary Exploration Quotes

“Planetary exploration satisfies our inclination for great enterprises and wanderings and quests that has been with us since our days as hunters and gatherers on the East African savannahs a million years ago. By chance—it is possible, I say, to imagine many skeins of historical causality in which this would not have transpired—in our age we are able to begin again.

Exploring other worlds employs precisely the same qualities of daring, planning, cooperative enterprise, and valor that mark the finest in military tradition. Never mind the night launch of an Apollo spacecraft bound for another world. That makes the conclusion foregone. Witness mere F-14s taking off from adjacent flight decks, gracefully canting left and right, afterburners flaming, and there’s something that sweeps you away—or at least it does me. And no amount of knowledge of the potential abuses of carrier task forces can affect the depth of that feeling. It simply speaks to another part of me. It doesn’t want recriminations or politics. It just wants to fly.”
― Carl Sagan, Pale Blue Dot: A Vision of the Human Future in Space

“I believe that the mind is the last planet that’s left unexplored—Achieving the universal or cosmic consciousness is the highest goal to mankind.”
― Mwanandeke Kindembo, What They Asked Me: The Fear of Living and Dying Young

“Just because there’s no one living on a planet does not mean it’s yours for the taking. Do you not see how dangerous that mindset is? Do you not think that treating the galaxy as if it is something to be endlessly used will always, always end in tragedy? You think you’ve broken the cycle. You haven’t. You’re in a less violent period of the exact same cycle, and you don’t see it. And the line of what you find to be justifiable cause is going to keep slipping and slipping until you end up right back where you started. You haven’t fixed anything. You put a stamp and a permit and a shiny coat of paint on an idea that has been fundamentally damaged from day one. You engaged in bloody theft and you called it progress, and no matter how much better you think you’ve made things, no matter how good your intentions are, that will always be the root of the GC. You cannot divorce any of what you do from that. Ever.”
― Becky Chambers, The Galaxy, and the Ground Within

“There are often evolutionary parallels on the different worlds because creation tends to be economical.”
― Julian May, Orion Arm

“Part of what drives us to explore and discover is the intangible: expanding our horizons, feeding our curiosity, finding all those unexpected things, and trying to answer those profound questions discussed in previous chapters, like how did the universe begin? How did life begin? Are we alone?”
― Nancy Atkinson, Incredible Stories from Space: A Behind-the-Scenes Look at the Missions Changing Our View of the Cosmos

“Every few days, Giordano Bruno has his revenge.”
― Michio Kaku, The Future of Humanity: Terraforming Mars, Interstellar Travel, Immortality and Our Destiny Beyond Earth

“While human spaceflight is certainly compelling – and it has always been a big part of my reporting career -- there is something about unmanned robotic spacecraft that has always tugged at my heart. These machines are our emissaries out into the cosmos, flung to faraway places that humans can’t yet visit. I grew up hearing about spacecraft like Mariner, Viking and Voyager boldly going on some of the first-ever deep space missions and making monumental discoveries that changed our view of the Solar System. They showed us worlds we previously could only dream about and artists could only imagine.”

― P.S. Jagadeesh Kumar

“PSJ Kumar's Laws of gravity and gravitational force
Law 6:
“The gravitational force experienced by any object on the surface of any planet will be the maximum and the gravitational force experienced by any object in the atmosphere of any planet will vary between the minimum and the maximum”
― P.S. Jagadeesh Kumar

“PSJ Kumar's Laws of gravity and gravitational force
Law 7:
"If any object enters into the gravitational field of any planet, the increase in the velocity of the object is directly proportional to the linear least square of its shortest distance and the maximum gravity from the surface of that planet”
― P.S. Jagadeesh Kumar

“PSJ Kumar's Laws of gravity and gravitational force
Law 8:
“The time taken for any object to move against the gravity of any planet will be more than the time taken for any object to move towards the gravity of any planet for a given distance, the decrease in the time taken to move towards the gravity will decrease with the increase in the mass of that object”
― P.S. Jagadeesh Kumar

“PSJ Kumar's Laws of gravity and gravitational force
Law 9:
“The time speed of any object in the weak gravitational force will be more than the time speed of any object in the strong gravitational force”
― P.S. Jagadeesh Kumar

“PSJ Kumar's Laws of gravity and gravitational force
Law 10:
“The diversion of any object onto the surface of any planet is the direct proportion of the mass and the velocity of that object to the continued proportion of the force applied against the object”
― P.S. Jagadeesh Kumar

“PSJ Kumar's Laws of gravity and gravitational force
Law 11:
“The gravity of any planet never ends at any given space rather the object has reached beyond the maximum gravitational force experienced on the surface of that planet and the minimum gravitational force experienced in the atmosphere of that planet”
― P.S. Jagadeesh Kumar

“PSJ Kumar's Laws of gravity and gravitational force
Law12:
"The time speed varies from one space to another space if its time zone varies irrespective of the gravitational field in any particular planet or in any particular position in the universe”
― P.S. Jagadeesh Kumar

“PSJ Kumar's Laws of gravity and gravitational force
Law 13:
"Any object that travels in the space and in the atmosphere of any planet do not lose or gain its weight including the light, the illusion of weight lost or gained by that object is due to its relative speed of motion with respect to the distance travelled against the gravitational force if any experienced by that object”
― P.S. Jagadeesh Kumar

“PSJ Kumar's Laws of gravity and gravitational force
Law 14:
