Where Are the Electrical Currents in the Enceladus Plume?

by Mark Zastrow 7 July 20172 February 2022

A plume of water ice that escapes Saturn’s moon Enceladus should be coursing with electrical currents, but data are mixed. Now simulations suggest that a sticky dust cloud may shield signals.

Retracing the First Spaceborne Electric Field Measurement

by Mark Zastrow 4 January 201710 February 2017

Fifty years ago, a sounding rocket made history by taking the first measurement of an electric field in space. What techniques were used to capture this data?

Half of Atmospheric Joule Heating Is Due to Small Oscillations

by A. K. Higginson 29 February 201629 February 2016

Scientists use sounding rockets to show that small oscillations in electric fields can be just as important for atmospheric Joule heating as the presence of the electric field itself.
