Space junk and climate change are two sides of the same coin.
The New York Times published an article about the consequences of increasing carbon dioxide. Major emission could produce a 3 percent reduction in the density of Earth’s upper atmosphere, a potential danger for satellites.
At the end of operation life, a satellite incinerates in the thicker lower atmosphere thanks to deorbiting, but a lowering density will diminish this effect.
In a possible scenario, access to space could become more difficult with the space junk increased 50 times by 2100 and carbon dioxide levels double the actual level.
That’s why it’s necessary to adopt debris mitigation practices with technical innovation like a more efficient propulsion system, to simplify and cut the time of deorbiting maneuvers.
