SOHO MDI Continuum Latest Image

The Space Radiation Group (SRG) at NASA Langley Research Center is concerned with protecting humans and electronics from the harmful effects of space radiation. This web site contains links to publications, including journal articles and NASA technical papers, that have been produced by the group (and some collaborators) since the year 2000. There are also links to two important radiation analysis software tools called OLTARIS (On-Line Tool for the Assessment of Radiation in Space) and NAIRAS (Nowcast of Atmospheric Ionizing Radiation System), which predict radiation environments for spacecraft and aircraft respectively. The picture to the right shows a SOHO real time image of the Sun.
