Answer 1

Space debris left from satellites poses a hazard to working spacecraft, and the number of objects in space continues to increase. NASA has experienced instances where spacecraft have been damaged by debris, and near-misses happen daily. NASA is concerned that the situation will worsen in the future.

Step-by-step explanation:

The subject of this question is Physics.

Step-by-step explanation:

1. According to NASA, there are more than 500 working satellites and 2,000 defunct satellites orbiting Earth.
2. There are also 1,400 used satellites and 1,100 smaller objects in space.
3. Since the beginning of space exploration in 1957, more than 137 satellites have exploded or broken apart while in orbit around the Earth.
4. Over time, even working spacecraft lose parts and screws.
5. The speed of these objects is several thousand kilometers per second.
6. At such high speeds, even tiny objects can cause huge problems.
7. NASA engineers believe that an electronic hit caused a dent on the door of the Columbia space shuttle.
8. So much debris has bounced off shuttles that NASA has had to replace 63 shuttle windows since 1981.
9. Several thousand near-misses involving debris and satellites happen every day.
10. NASA is concerned that the situation will only worsen.
