Today's scenery in space is not a pretty picture.

With the rate at which orbital launches are now occurring, some Earth orbits are so crowded and carry so many potentially dangerous, high-velocity pieces of defunct satellite litter and spent rocket stages that they could jeopardize humanity's future in space. That's the output from experts at the European Space Agency (ESA), waving a number of cautionary flags in its new Space Environment Report 2026. In brief, this disquieting appraisal from ESA points out that the number and scale of commercial satellite constellations continues to increase each year.

The report estimates that the casualty risk from reentering rocket upper stages alone was over four percent in 2024, having doubled since 2020, points out space environment specialist, Ewan Wright from the University of British Columbia, Vancouver, British Columbia, Canada. About 124 rocket stages reentered the atmosphere uncontrolled in 2024; over two per week, Wright told Space.com. "If that level is sustained for the next decade, the risk of someone somewhere being killed by rocket debris alone is 33 percent," he said.
