5 /PRNewswire-USNewswire/ A NASA-funded study describeshow extreme solar eruptions could have severe consequences for communications,power grids and other technology on Earth.(Logo: http://)The National Academy of Sciences in Washington conducted the study. Theresulting report provides some of the first clear economic data thateffectively quantifies today's risk of extreme conditions in space driven bymagnetic activity on the sun and disturbances in the near-Earth environment.Instances of extreme space weather are rare and are categorized with othernatural hazards that have a low frequency but high consequences. "Obviously, the sun is Earth's life blood," said Richard Fisher, director ofthe Heliophysics division at NASA Headquarters in Washington. "To mitigatepossible public safety issues, it is vital that we better understand extremespace weather events caused by the sun's activity."Besides emitting a continuous stream of plasma called the solar wind, the sunperiodically releases billions of tons of matter called coronal massejections. These immense clouds of material, when directed toward Earth, cancause large magnetic storms in the magnetosphere and upper atmosphere.

Suchspace weather can affect the performance and reliability of space-borne andground-based technological systems. Space weather can produce solar storm electromagnetic fields that induceextreme currents in wires, disrupting power lines, causing wide-spreadblackouts and affecting communication cables that support the Internet. Severespace weather also produces solar energetic particles and the dislocation ofthe Earth's radiation belts, which can damage satellites used for commercialcommunications, global positioning and weather forecasting. Space weather hasbeen recognized as causing problems with new technology since the invention ofthe telegraph in the 19th century. A catastrophic failure of commercial and government infrastructure in spaceand on the ground can be mitigated through raising public awareness, improvingvulnerable infrastructure and developing advanced forecasting capabilities.Without preventive actions or plans, the trend of increased dependency onmodern space-weather sensitive assets could make society more vulnerable inthe future.
