Earth\u2019s orbit is becoming increasingly crowded with dangerous space debris, and engineers warn the problem could keep worsening even if all rocket launches stopped today.<\/p>\n
More than 33,000 tracked objects are currently orbiting Earth at speeds approaching 28,000 km\/h, according to data from Space-Track and the US Space Surveillance Network. Scientists say even tiny fragments can damage spacecraft, satellites, and stations operating in low Earth orbit.<\/p>\n
The growing buildup of debris is raising concerns over a cascading chain reaction known as the Kessler Syndrome, where collisions between objects generate even more debris, increasing the likelihood of future crashes.<\/p>\n
According to the report, Earth\u2019s orbit now contains more than 15,800 tonnes of material, equivalent to roughly 40 jumbo jets fragmented into high-speed objects.<\/p>\n
Orbit risks intensify<\/p>\n
Researchers say nearly half of all tracked objects in orbit are already classified as debris. Out of 33,269 tracked objects, 12,550 are debris fragments while 17,682 are payloads, or satellites.<\/p>\n
This means there are roughly seven tracked debris objects for every 10 satellites currently operating in orbit.<\/p>\n
\u201cThe danger isn\u2019t necessarily how much debris is in space, it\u2019s the density and velocity of the debris,\u201d the report noted.<\/p>\n
Emily Sacchi, Aerodynamics Engineer at Bath University Rocketry Team, warned that the situation may continue deteriorating regardless of future launch activity.<\/p>\n
\u201cEven in a scenario where no further launches take place, debris levels would still increase, as collisions and fragmentation events generate new debris faster than existing objects can naturally re-enter the atmosphere.\u201d<\/p>\n
The report identified China, the CIS, and the United States as the largest contributors to orbital debris. China\u2019s share is linked largely to its 2007 anti-satellite test, while US debris figures include fragments generated by the 2009 collision between Iridium 33 and Kosmos 2251.<\/p>\n
Researchers also highlighted a growing environmental concern linked to debris re-entry. Materials such as aluminium<\/a>, copper, and lithium vaporize into particles that can remain suspended in the upper atmosphere and potentially affect atmospheric chemistry and ozone levels.<\/p>\n Cleanup technologies advance<\/p>\n Governments, space agencies, and private firms are now investing heavily in technologies designed to remove debris from orbit before the problem escalates further.<\/p>\n The European Space Agency is backing the ClearSpace-1 mission, expected to launch in 2029, which aims to capture debris using robotic arms. Other technologies under development include magnetic capture systems,<\/a> electrodynamic tethers, harpoons, drag sails, and laser-based debris removal systems.<\/p>\n \u201cRobotic arms and claw-like mechanisms are adaptable beyond one-off debris removal,\u201d said Surabhi Sathish, Propulsion Engineer at Bath University Rocketry Team.<\/p>\n \u201cThe same technologies can support inspection, in-orbit servicing, refuelling and life-extension, which makes them more commercially sustainable.\u201d<\/p>\n However, experts caution that large-scale debris removal remains technically difficult and extremely expensive.<\/p>\n \u201cActive debris removal has yet to be demonstrated on a commercial level,\u201d said Hrishi Dave, Propulsion Lead at Bath University Rocketry Team.<\/p>\n
