Read a passage about the problem of space junk.
Cleaning Up the Skies
Since the beginning of the space age in the 1950s, thousands of
rockets and satellites have been launched into space.
Most have
functioned as they were designed to, but over time, some machines
have broken down and remain floating around in space because they
are difficult to bring back.
Dead satellites, used rocket parts, and small
pieces of dirt are in orbit.
Those objects left unattended in space are
collectively referred to as space junk.
The presence of space junk
significantly increases risks to space activities and the safety of
astronauts.
For example, small pieces of junk might not seem like a big
issue, but they move at 6.7 kilometers per second.
At that speed, even a
small piece of metal can seriously harm satellites that provide services
across the world.
In addition, each crash has the potential to generate
more space junk.
Without active efforts to remove the junk, traveling in
space would be extremely dangerous.

Cleaning Up the Skies
하늘 청소하기
Since the beginning of the space age in the 1950s, thousands of rockets and satellites have been launched into space.
1950년대 우주 시대가 시작된 이래로 수천 개의 로켓과 위성이 우주로 발사되었다.
Most have functioned as they were designed to, but over time, some machines have broken down and remain floating around in space because they are difficult to bring back.
대부분은 설계된 대로 작동했지만, 시간이 지나면서 일부 기계는 고장이 나서 우주에 떠돌아다니는 채로 남겨진 경우가
있는데 왜냐하면 그것들은 다시 가져오기 어렵기 때문이다.
Dead satellites, used rocket parts, and small pieces of dirt are in orbit.
작동을 안 하는 인공위성, 사용된 로켓 부품, 그리고 작은 먼지 조각들이 궤도를 돌고 있다.
Those objects left unattended in space are collectively referred to as space junk.
우주에 방치된 이러한 물체들을 통칭하여 우주 쓰레기라고 한다.
The presence of space junk significantly increases risks to space activities and the safety of astronauts.
우주 쓰레기의 존재는 우주 활동과 우주 비행사의 안전에 대한 위험을 상당히 증가시킨다.
For example, small pieces of junk might not seem like a big issue, but they move at 6.7 kilometers per second.
예를 들어, 작은 쓰레기 조각은 큰 문제가 되지 않을 것 같지만, 그것들은 초당 6.7km의 속도로 움직인다.
At that speed, even a small piece of metal can seriously harm satellites that provide services across the world.
그 속도에서는, 작은 금속 조각 하나도 전 세계에 서비스를 제공하는 위성에 심각한 피해를 줄 수 있다.
In addition, each crash has the potential to generate more space junk.
게다가 각각의 충돌은 더 많은 우주 쓰레기를 발생시킬 가능성이 있다.
Without active efforts to remove the junk, traveling in space would be extremely dangerous.
쓰레기를 제거하려는 적극적인 노력이 없다면, 우주로의 여행은 매우 위험할 것이다.
