Space weather

DTU Space is leading a joint European project tasked with mapping the effect of so-called CMEs (coronal mass ejections) from the Sun on electrical systems on Earth and aboard satellites, and determining whether this phenomenon presents a health hazard to astronauts

The CME project is part of a major joint European collaboration tasked with examining the interaction between the Sun and the Earth in general. This interaction creates the so-called space weather, which is of particular importance to astronauts, satellites and space probes. Among other things, CMEs can affect radio communication and GPS, and present a radiation hazard for airline passengers flying on polar routes.

DTU Space’s project responsibilities centre on collecting data about sunspots and CMEs, and making these data accessible to scientists. Hopefully, data collection and monitoring of sunspots and CMEs will result in a better understanding and better predictions of space weather.

Facts about space weather 

Space weather is a modern term for conditions in space, including the intensity of hard radiation, the strength of electrical and magnetic fields, electrical currents and other disturbances.
