Like a ball on a cosmic pool table, Discovery had bounced off the moving gravitational field of Jupiter, and had gained momentum from the impact. Without using any fuel, she had increased her speed by several thousand miles an hour…” quote by Arthur C. Clarke](https://sms4smile.com/quotes/i/0ad/arthur-c-clarke-640_nature_jupiter-s-fly-by-had-been-carried-out-wi_1774789.jpg) [Download](https://sms4smile.com/quotes/i/0ad/arthur-c-clarke-640_nature_jupiter-s-fly-by-had-been-carried-out-wi_1774789.jpg) [Open image](https://sms4smile.com/quotes/i/0ad/arthur-c-clarke-640_nature_jupiter-s-fly-by-had-been-carried-out-wi_1774789.jpg) > ““Jupiter's fly-by had been carried out with impeccable precision. Like a ball on a cosmic pool table, Discovery had bounced off the moving gravitational field of Jupiter, and had gained momentum from the impact. Without using any fuel, she had increased her speed by several thousand miles an hour. Yet there was no violation of the laws of mechanics; Nature always balances her books, and Jupiter had lost exactly as much momentum as Discovery had gained. The planet had been slowed down - but as its mass was a sextillion times greater than the ship's, the change in its orbit was far too small to be detectable. The time had not yet come when Man could leave his mark upon the Solar System.”” [Arthur C. Clarke](https://sms4smile.com/quotes/author/arthur-c-clarke/) ## About This Quote This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation. The spacecraft used Jupiter’s gravity to gain speed without fuel, illustrating nature’s conservation of momentum and the tiny effect on massive bodies. **In simple terms:** Gravity assists let ships gain speed while massive planets barely notice. Key Takeaway Use gravity assists for efficient travel. Themes physics space travel conservation exploration Mood inspirational educational Type scientific technical When to use this quote - spacecraft design - interplanetary missions - scientific education Key Concepts gravity assist momentum exchange energy efficiency Questions to Reflect On - What other planetary assists could be used? - How does this affect mission planning? A Different Perspective Relying on gravity limits maneuverability near massive bodies. ★ ★ ★ ★ ★ No ratings yet [Discovery Gained](https://sms4smile.com/quotes/about/discovery-gained-1810535/) [Gained Planet](https://sms4smile.com/quotes/about/gained-planet-1810537/) [Jupiter Gained](https://sms4smile.com/quotes/about/jupiter-gained-1810533/) [Jupiter Lost](https://sms4smile.com/quotes/about/jupiter-lost-1810534/) [Nature](https://sms4smile.com/quotes/about/nature/) [Planet Slowed](https://sms4smile.com/quotes/about/planet-slowed-1810536/) [Pool table](https://sms4smile.com/quotes/about/pool-table/) [Solar system](https://sms4smile.com/quotes/about/solar-system/) [Thousand miles](https://sms4smile.com/quotes/about/thousand-miles/) [Without u](https://sms4smile.com/quotes/about/without-u/) ## Related quotes > [“The way my body instantly reacted to his stare—that was definitely trouble.
