Human increases in carbon dioxide emissions are thinning the Earth's outer atmosphere, making it easier to keep the space station aloft but prolonging the life of dangerous space debris.
New research indicates that global warming is decreasing atmospheric density in low-earth orbits which will accelerate the orbit of existing space debris and significantly increase the risk of collisions.
New research shows that the sun is more active now than it has been for over 1100 years. The increase in solar activity will have an impact on satellites, energy grids, and the current debate over global warming.
