본문내용

Since the first artificial satellite called Sputnik 1 was launched by the Soviet Union in 1957, many countries have launched projectiles in space to gain many kinds of information and demonstrate developed technologies. According to Kim (2015), the number of projectiles launched by countries is approximately 3,000. But the total number is more than 6,600 when the number of informal spy and military satellites is included. This lead to a lot of space junk which is defined that it is debris after rockets are separated from a satellite, a space shuttle and a missile and the old satellites which cannot operate are also artificial space debris. This essay will describe two main causes of the increase in space junk in earth orbit in terms of the space race and the Kessler Syndrome as well as the effects on humans and present circumstances to overcome it.
