[June Theme Report] Space Pollution

by Alex Kim | 01-07-2023 00:57


Space pollution, sometimes referred to as space debris or orbital debris, is the buildup of manufactured items in Earth's orbit that are no longer usable. Satellites, spacecraft, and the long-term viability of space activities are all seriously threatened by this junk. The problem of space pollution is becoming more urgent as human space exploration and satellite deployments rise. The goal of this paper is to examine the issue of space pollution, highlight noteworthy examples, talk about potential remedies, and emphasize the value of international cooperation in resolving this widespread issue.

Examples:

Fragmentation Debris: Produced when bigger objects split into multiple smaller fragments, fragmentation debris poses a major concern because of its rapid velocity and unpredictable nature. The amount of debris in some orbits has dramatically increased as a result of the collision between a retired Chinese spacecraft and an inactive Russian satellite in 2007.

Space pollution is a result of several non-operational satellites and leftover rocket stages that are still in orbit. For instance, in order to prevent collisions with retired satellites and rocket stages, the International Space Station (ISS) has had to execute debris-avoidance maneuvers.

Discarded Equipment: The problem of space pollution is getting worse due to the discarding of equipment from space missions, including lens covers, spent rocket fairings, and other debris. These objects, if left unattended, contribute to the overall debris population in Earth's orbit.

Solutions:

Technology development is essential for active debris removal from space (ADR). Techniques like deorbiting debris to burn up in Earth's atmosphere after capturing it with robotic arms, nets, or harpoons show potential. These techniques can lessen the likelihood of accidents while also reducing the overall population of space debris.

Responsible spaceship design can reduce the production of space trash by implementing rules and regulations. This involves making sure satellites have efficient propulsion systems for final movements, which lowers the possibility that they will finish up as inactive trash.

Improved Tracking and Monitoring: More precise data on the locations and motions of space debris can be obtained from improved tracking and monitoring systems, allowing spacecraft operators to take the appropriate evasive measures to avoid collisions. International guidelines and cooperation are necessary to manage space pollution on a global scale. The creation of standards, ideal procedures, and protocols to reduce space debris can be facilitated by international agreements like the COPUOS of the United Nations. 

Conclusion:

Future space research, satellite operations, and the viability of activities in Earth's orbit are all seriously threatened by space pollution. The examples of space pollution covered in this study demonstrate how urgent it is to address this problem. In order to reduce space pollution, it is important to use active debris removal techniques, responsible spacecraft design principles, improved tracking systems, and promote international cooperation. The international community can cooperate to protect the long-term sustainability of space activities and guarantee a sustainable space environment for future generations by giving priority to these efforts.
