NASA’s ICON Mission Ends with Several Ionospheric Breakthroughs

After contributing to many important findings on the boundary between Earth’s atmosphere and space — an area where space weather can interfere with both satellites and communications signals — NASA’s ICON (Ionospheric Connection Explorer) mission has come to an end.

Watch Carbon Dioxide Move Through Earth’s Atmosphere

What we’re looking at This global map shows concentrations of carbon dioxide as the gas moved through Earth’s atmosphere from January through March 2020, driven by wind patterns and atmospheric circulation. Because of the model’s high resolution, you can zoom in and see carbon dioxide emissions rising from power plants, fires, and cities, then spr
