Our rockets, on the other hand, are accelerating bodies, there is no need to exceed 11km/s, in fact, they don't. The highest speed of rockets within the Earth's atmosphere is about 7km/s. – varun Oct 13, 2024 at 20:04 1
WebA spacecraft leaving the surface of Earth, for example, needs to be going about 11 kilometers (7 miles) per second, or over 40,000 kilometers per hour (25,000 miles per hour), to enter orbit. An Endless Cycle Achieving escape velocity is one of the biggest challenges facing space travel. WebDue to their high exhaust velocity—2,500 to 4,500 m/s (9,000 to 16,200 km/h; 5,600 to 10,100 mph)—rockets are particularly useful when very high speeds are required, such as orbital speed at approximately 7,800 m/s (28,000 km/h; 17,000 mph).
WebMay 13, 2024 · The exact speed needed to orbit the earth depends on the altitude, according to a formula that was developed by Johannes Kepler in the early 1600's: V = sqrt ( g0 * Re^2 / (Re + h) ) where V is the velocity for a circular orbit, g0 is the surface gravitational constant of the Earth (32.2 ft/sec^2), Re is the mean Earth radius (3963 miles), and ...
