Space, a vast expense that extends outside of Earth's dimensions. It has long been regarded as a pristine and untouched environment. However, with the advancement of human space exploration and satellite deployment, concerns have emerged regarding the potential for space pollution. As long as humans launch objects into orbit, space debris is inevitable.
Space pollution refers to the accumulation of human-made debris, the emission of harmful substances, and the alteration of natural conditions in space. This article will explore the challenges posed by space pollution and discusses potential solutions to mitigate its impact.  One of the primary concerns in the space environment is the Accumulation of Space Debris. This includes defunct satellites, spent rocket stages, and fragments generated from collisions or explosions. These objects travel at high speeds and pose a significant threat to operational satellites and spacecraft. The growing number of satellites being launched into space exacerbates this problem. Efforts are underway to develop strategies for debris mitigation, such as designing satellites for re-entry or using active debris removal technologies. The increasing number of satellites in orbit has led to a surge in Radio Frequency Interference (RFI). RFI occurs when different signals interfere with each other, affecting satellite communications and hindering astronomical observations. International regulations and guidelines are being established to manage and allocate radio frequencies more efficiently, reducing the potential for RFI and allowing for harmonious coexistence among satellites.  In addition, Spacecraft and Satellites employ various chemicals and propellants for propulsion and operation. When not managed properly, these substances can contribute to Chemical Contamination in space. Efforts are underway to minimize the release of hazardous materials during satellite deployments and to design propulsion systems that use greener and less toxic propellants. Additionally, satellite operators are increasingly considering end-of-life disposal methods that aim to minimize contamination risks. The prospect of space mining and resource extraction introduces potential environmental concerns. Extracting resources from celestial bodies could lead to the Alteration of Natural Compositions and disrupt their delicate ecosystems. Developing sustainable practices and establishing regulations to ensure responsible resource extraction are crucial to mitigate the potential ecological impact.  Preserving the space environment is crucial for the long-term sustainability of space exploration and utilization. Space pollution presents complex challenges, but with international collaboration, technological advancements, and regulatory frameworks, we can address these issues. By promoting responsible space practices, implementing debris mitigation strategies, and minimizing pollution, we can protect the space environment and ensure its availability for future generations of explorers and scientists. |

Hello Cheryl! This is your mentor Yewon.
Before I start, I apologize for the late comment.
You have written a report about the space environment and pollution, which was our theme for June!
Beginning with the definition of space pollution, your report contains lots of informative knowledge that helps the readers to understand the space environment well.
Thank you for your meaningful report! Great job!

Hello Cheryl! This is your mentor James.
In this report, you've explained the main causes of space pollution and its dangerous consequences. Among the results of constant debris accumulation, I think the increased risk of collisions during future missions and expeditions is the most detrimental effect. As you've mentioned, presently operational satellites may also collide with the fragments, which would harass its functions of information transmittance. Also, chemical contamination is a great point to make since chemical species like fuel, battery acid, and engine oil may be spilt from broken satellites.
Thank you for your fantastic work! Let's keep it up with your next report as well.
