Earth’s orbit is becoming increasingly crowded with dangerous space debris, and engineers warn the problem could keep worsening even if all rocket launches stopped today,El.kz cites Interesting Engineering.
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.
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.
According to the report, Earth’s orbit now contains more than 15,800 tonnes of material, equivalent to roughly 40 jumbo jets fragmented into high-speed objects.
Orbit risks intensify
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.
This means there are roughly seven tracked debris objects for every 10 satellites currently operating in orbit.
“The danger isn’t necessarily how much debris is in space, it’s the density and velocity of the debris,” the report noted.
Emily Sacchi, Aerodynamics Engineer at Bath University Rocketry Team, warned that the situation may continue deteriorating regardless of future launch activity.
“Even 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.”
The report identified China, the CIS, and the United States as the largest contributors to orbital debris. China’s 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.
Researchers also highlighted a growing environmental concern linked to debris re-entry. Materials such as aluminium, copper, and lithium vaporize into particles that can remain suspended in the upper atmosphere and potentially affect atmospheric chemistry and ozone levels.
