Rise of atmospheric CO2 can cause more space junk collisions

Rise of atmospheric CO2 can cause more space junk collisions

Rise of atmospheric carbon dioxide in upper level of Earth’s atmosphere is expected to gradually result in a cooler, more contracted high-altitude atmospheric layer or thermosphere, and a consequent reduction in the atmospheric drag experienced by satellites,

Ground-Based Lasers Vie With Satellites To Map Earth’s Magnetic Field

Mapping the Earth’s magnetic field – to find oil, track storms or probe the planet’s interior – typically requires expensive satellites. University of California, Berkeley, physicists have now come up with a much cheaper way to measure the Earth’s magnetic field
