Thirteen companies are competing to cover the entire Earth with high-speed wireless Internet from low-orbit satellites within one to two years. This would be an ecological and public health nightmare. The biggest players are SpaceX (12,000 satellites), OneWeb (4,560 satellites) and Boeing (2,956 satellites).
The recent finding, in 2018, that stratospheric ozone is still declining despite the Montreal Protocol took everyone by surprise. The increasing pace of ever-more-powerful rocket launches is a likely factor. Imminent plans for beaming high-speed Internet from space would require the launching of large rockets almost daily. This is expected to alter, if not destroy, the ozone layer and contribute significantly to climate change. Although many new rockets burn liquid fuel containing no ozone-destroying chlorine, the assumption that this is environmentally friendly is proving wrong.
Martin Ross and colleagues at the Aerospace Corporation have been sounding the alarm. Their 2009 paper, “Limits on the Space Launch Market Related to Stratospheric Ozone Depletion,” pointed out that although liquid fuels do not contain chlorine, they produce significant amounts of nitrogen and hydrogen oxides, as well as water vapor and soot, when burned. All of those destroy ozone.
Martin Ross of the Aerospace Corporation was also the lead author of a paper published in 2010 titled “Potential climate impact of black carbon emitted by rockets.” The authors developed a computer model to predict what would happen in different parts of the planet if the number of launches burning kerosene (then 25 annually) increased by a factor of ten. His model predicts as much as a 4% loss of ozone over the tropics and subtropics, as much as a 3-degree Celsius summertime increase in temperature over the South Pole, more than a one-degree overall increase in Antarctic temperature, and a decrease in Antarctic sea ice by 5% or more.
