Question

Different between codita and non codita

Answer 1

The CODITA project was designed to answer two overarching questions: how much cosmic dust enters the Earth’s atmosphere every day, and what impact does the dust have throughout the atmosphere? Estimates of the rate of input of cosmic dust into the Earth’s atmosphere vary from about 3 to 300 tonnes per day, depending on how this is measured. The highest values tend to come from spaceborne measurements and the accumulation rates of “cosmic” elements such as Iridium, Platinum and Osmium in deep-sea sediments and ice cores.
