How NASA Uses Gravity to Boost Spacecraft Speed — The Genius of Gravity Assist 🌍🚀

History Photographed on Instagram: "This is the phenomenon of astronauts temporarily having difficulty readjusting to Earth's gravity after spending time in space.⁠ ⁠ This condition, which is called orthostatic intolerance, is a condition where the bodies struggle to adjust to Earth’s gravity in an upright position. ⁠ ⁠ In space, their bodies adapt to microgravity, which weakens leg muscles and causes cardiovascular changes. ⁠ ⁠ Back on Earth, standing up can lead to a sudden drop in blood press

Knowledge on Instagram: "According to Einstein’s theory of General Relativity, gravity affects the flow of time through a phenomenon called gravitational time dilation. The stronger the gravitational field, the slower time passes relative to areas with weaker gravity. Near massive objects like planets, stars, or black holes, clocks tick more slowly. This effect is measurable with precise atomic clocks and is crucial for technologies like GPS. Near a black hole, seconds can equal years far away,
