The international space station travels at a distance of about 250 miles above Earth’s surface and at a speed of 17,500 miles per hour. Even though space dust and debris can be tiny, 1 centimeter or less in size with a mass of 10 grams or less, there is always fear that the space station will sustain damage from a collision with a small piece of space debris. Why should scientists be concerned about a collision with such a tiny object? Use evidence and scientific reasoning to explain your answer.

Because of Microgravity

Explanation:

Because of Microgravity, some people think that there is no gravity in space. But small amounts of gravity are everywhere. Gravity keeps the moon in orbit around Earth. It keeps Earth in orbit around the sun. The pull of gravity gets weaker the farther apart two objects are. A spacecraft could go so far from Earth that a person would feel very little gravity. But this is not why things float on the International Space Station. The space station orbits Earth at about 200 to 250 miles high. At that height, Earth's gravity is still very strong. In fact, a person who weighs 100 pounds on the ground would weigh 90 pounds there.
