**Space Nations Urgently Race to Clean 6,000 Tons of Orbital Junk**
*“Debris removal or in‑orbit servicing also will become something like a rocket industry,” Dr. Phanindra explains.*

### Introduction
Low‑Earth orbit is filling up faster than ever. With more than 6,000 metric tons of defunct satellites, spent rocket stages and fragments circling the planet, the risk of collisions threatens both current missions and the future of space economy that once focused national space agencies and private firms are now accelerating efforts to clear the clutter before a cascade of impacts makes key orbital lanes unusable.

### Key Developments
Recent months have seen a flurry of activity. The United States’ Orbital Sustainability Act, passed in late 2023, earmarks $1.2 billion for active debris removal (ADR) demonstrations over the next five years. Europe’s Clean Space Initiative has funded three prototype “space tugs” designed to capture and de‑orbit large objects using robotic arms and nets. In Asia, Japan’s JAXA and India’s ISRO announced a joint mission slated for 2026 that will test a laser‑based nudging system on mid‑size debris. Meanwhile, commercial players such as Astroscale and ClearSpace have secured multi‑year contracts with national agencies, signaling a shift from purely governmental projects to market‑driven services.

### Industry Analysis
The emerging debris‑pains of the orbital environment are creating a new sector that mirrors the early days of launch services. Analysts note that the economics of debris removal hinge on three factors: cost per kilogram removed, reliability of capture mechanisms, and regulatory incentives. Current estimates place the price of removing a ton of junk between $5 million and $10 million, but economies of scale and reusable servicing vehicles could drive that figure down by 40 % within a decade.
