Why are satellites normally sent into orbit by firing them in an easterly direction? Based on this, explain why the International Space Station (ISS) orbits the Earth at about 17,500 miles per hour at an altitude above Earth’s surface of about 230 miles. Would it be more efficient to have a higher or lower orbit for the ISS? Explain in detail why or why not.
