Interactive NASA Space Physics Ionosphere Radio Experiments (INSPIRE)

Main Project Information
Task Use build-it-yourself kits to record low frequency emissions.
Where anywhere

INSPIRE volunteers use build-it-yourself kits to measure and record very low frequency radio emissions. These include naturally occurring "sferics" (short for "atmospherics") often generated by lightning and known as "tweeks," "whistlers," and "chorus" as well as man-made emissions.

There is a great deal of scientific curiosity about the nature and generation mechanisms of natural very low frequency radio emissions and how they interact with the Earth's ionosphere and magnetic fields. INSPIRE is taking an active role in furthering the investigation of very low frequency emissions by involving citizen volunteers in its research.

INSPIRE represents a rare opportunity to work with real NASA space scientists on real scientific problems.
