SOLAR SYSTEM

Detailed explanation-1: -The space shuttle gains more altitude above Earth and the speed increases to the nearly 7, 850 m/s (17, 500 mph) required to achieve orbit.

Detailed explanation-2: -1. What country launched the world’s first man-made satellite, Sputnik, into Earth orbit on October 4, 1957? 2. Because Sputnik travels at 18, 000 mph, it can make an orbit of Earth every minutes.

Detailed explanation-3: -Like any other object in low-Earth orbit, a Space Shuttle must reach speeds of about 17, 500 miles per hour (28, 000 kilometers per hour) to remain in orbit.

Detailed explanation-4: -How long does it take the shuttle to orbit the Earth once? It takes approximately 90 minutes for the orbiter to go around the Earth one time, moving at 17, 500 miles per hour.

Detailed explanation-5: -The Space Shuttle has been measured at speeds over 17, 000 miles per hour (27, 359 kph), and the Apollo manned spacecraft traveled at 24, 500 miles/hour (39, 428 kph) between the earth and the moon ― the fastest a person has ever traveled.
