....Orbiting Trouble: The Rising Threat of Space Junk Around Earth"<br>By: - YAGAY andSUN<br>Environmental Law<br>Dated:- 31-5-2025<br>High above the Earth's surface, far beyond the range of commercial airliners and weather systems, a silent crisis is unfolding. Orbiting our planet is a growing cloud of man-made debris-fragments of defunct satellites, spent rocket stages, and bits of broken spacecraft....

..... Collectively known as space junk, this debris poses an increasingly serious threat to the future of space exploration, satellite communication, and even life on Earth. What Exactly Is Space Junk? Space junk, also referred to as orbital debris, includes any non-functional, human-made object left in Earth's orbit. It can be as large as an abandoned satellite or as small as a flake of paint. ....

....Though tiny fragments may seem harmless, their danger lies in speed. Objects in low Earth orbit (LEO) travel at speeds exceeding 27,000 kilometers per hour (about 17,000 miles per hour). At such velocity, even a millimeter-sized fragment can damage or destroy active satellites or spacecraft. This junk is scattered across different orbital zones, including LEO (up to 2,000 km above Earth), medium ....

....Earth orbit (MEO), and geostationary orbit (GEO, about 35,786 km above Earth). Each zone serves specific purposes-such as Earth observation, GPS navigation, or telecommunications-and all are increasingly crowded. How Did It Get There? Space junk has accumulated over decades of human activity in space. Since the launch of Sputnik 1 in 1957, thousands of satellites and missions have been sent into....

.... orbit. While many satellites are operational, a significant number have reached the end of their lifespans and remain as lifeless objects circling the Earth. Key contributors to space debris include: * Explosions of fuel tanks or batteries left on defunct spacecraft. * Collisions between satellites, both accidental and intentional (such as anti-satellite weapon tests). * Rocket stages jett....

....isoned after launches, which sometimes fragment. * Microscopic particles like bolts, insulation, and even astronaut tools that drift away during spacewalks. A notable example is the 2009 collision between a defunct Russian satellite and a functioning U.S. Iridium communications satellite, which produced thousands of debris pieces. Similarly, in 2007, China tested an anti-satellite missile on on....

....e of its weather satellites, generating over 3,000 large debris fragments. Why It's a Growing Threat As space becomes more accessible and the number of launches increases-driven by commercial satellite constellations, private companies, and national space programs-the risk of collisions escalates dramatically. Each new piece of debris adds to a chain reaction known as the Kessler Syndrome, a sce....

....nario where debris collisions generate more debris, further increasing the likelihood of additional collisions. The consequences are wide-reaching: * Damage to Satellites: Communications, weather forecasting, navigation, and Earth observation depend on satellites that are increasingly at risk. * Threats to Space Missions: Crewed missions, such as those aboard the International Space Station, ....

....must regularly adjust orbits to avoid potential collisions. * Economic Impact: Damaged satellites lead to service outages and costly replacements. Insurance premiums for satellite operators are also rising. * Barrier to Future Exploration: Launching new missions becomes more dangerous and expensive as orbits become more congested. What's Being Done to Address It Governments, space agencies, ....

....and private firms are recognizing the urgency of managing orbital debris and are exploring several strategies: * Passive Measures: Designing satellites with shorter operational lifespans and systems to deorbit them safely at the end of their use. * Active Debris Removal (ADR): Innovative technologies such as space nets, harpoons, robotic arms, and even lasers are being tested to capture or red....

The Role of Policy and Global ....

....Cooperation Managing space junk is not merely a technological challenge but also a diplomatic one. Earth's orbit is a shared domain, and cooperation across borders is essential. Binding international agreements, akin to maritime or aviation regulations, may be necessary to enforce responsible behavior and prevent activities that generate unnecessary debris. Private companies launching large sate....

....llite constellations also have a role to play. Transparent practices, proper end-of-life planning, and compliance with debris mitigation standards must become the industry norm. Conclusion Space junk may be invisible to the naked eye, but its impact is tangible and escalating. As humanity becomes more dependent on space for communication, navigation, and research, the orbital environment must be....
