Projected Increase in Space Travel May Damage Ozone Layer

SILVER SPRING, Md. (NOAA PR) — Projected growth in rocket launches for space tourism, moon landings, and perhaps travel to Mars has many dreaming of a new era of space exploration. But a NOAA study suggests that a significant boost in spaceflight activity may damage the protective ozone layer on the one planet where we live. 

Kerosene-burning rocket engines widely used by the global launch industry emit exhaust containing black carbon, or soot, directly into the stratosphere, where a layer of ozone protects all living things on the Earth from the harmful impacts of ultraviolet radiation, which include skin cancer and weakened immune systems in humans, as well as disruptions to agriculture and ecosystems.

A wave of new applications submitted to the Federal Communications Commission (FCC) last week for approval for communications satellites operating in the V band has sent the number of spacecraft in large constellations soaring to nearly 100,000.

A list compiled by Parabolic Arc shows that 94,255 satellites are included in the constellations. That number includes 29,439 satellites approved by the FCC or in development in China. The FCC has applicants pending before it for another 64,816 satellites.
