š„CO2, Thermosphere Contraction, and Space Collision Risks
A recent study indicates that increased greenhouse gas emissions are causing Earth's upper atmosphere to contract.Ā This contraction reduces atmospheric drag on satellites and space debris in low Earth orbit.Ā Consequently, defunct objects will remain in orbit longer, elevating the risk of collisions with operational satellites.Ā Simulations project a significant decrease in orbital carrying capacity by 2100, particularly during solar minimums.Ā This overcrowding increases the potential for Kessler syndrome, a cascade of collisions that could severely limit future space activities.Ā The findings underscore the interconnectedness of climate change and space sustainability, necessitating urgent action on both fronts.
