Spatio-temporal structure of storm-time chorus
 We discuss chorus emissions measured by the four Cluster spacecraft at close separations during a geomagnetically disturbed period on 18 April 2002. We analyze the lower band of chorus below one…
An update to a Saturnian longitude system based on kilometric radio emissions
 The period of Saturn kilometric radiation modulation as determined by Voyager forms the basis for a longitude system (SLS) recognized by the International Astronomical Union. However, Ulysses and…
A search for life on Earth from the Galileo spacecraft
In its December 1990 fly-by of Earth, the Galileo spacecraft found evidence of abundant gaseous oxygen, a widely distributed surface pigment with a sharp absorption edge in the red part of the…
In Situ Observations of Interstellar Plasma with Voyager 1
Electron densities detected by Voyager 1 show that the spacecraft is in the interstellar plasma, and other observations provide strong evidence that Voyager 1 has crossed the heliopause into the nearby interstellar plasma.
The Earth as a radio source: Terrestrial kilometric radiation
- D. Gurnett
- 1 October 1974
Radio wave experiments on the Imp 6 and 8 satellites have shown that the earth emits very intense electromagnetic radiation in the frequency range of about 50–500 kHz. At peak intensity the total…
Variation of the Martian Ionospheric Electron Density from Mars Express Radar Soundings
 The Mars Advanced Radar for Subsurface and Ionospheric Sounding aboard Mars Express has been in operation for over 2 years. Between 14 August 2005 and 31 July 2007, we obtain 34,492 ionospheric…
Subsurface Radar Sounding of the South Polar Layered Deposits of Mars
The ice-rich south polar layered deposits of Mars were probed with the Mars Advanced Radar for Subsurface and Ionospheric Sounding on the Mars Express orbiter, suggesting a composition of nearly pure water ice.
The Variable Rotation Period of the Inner Region of Saturn's Plasma Disk
We show that the plasma and magnetic fields in the inner region of Saturn's plasma disk rotate in synchronism with the time-variable modulation period of Saturn's kilometric radio emission. This…
CRRES plasma wave experiment
The CRRES plasma wave experiment is designed to provide information on the plasma wave environment and the total plasma density in the Earth's radiation belts and throughout the CRRES orbit. This…
The Cassini Radio and Plasma Wave Investigation
The Cassini radio and plasma wave investigation is designed to study radio emissions, plasma waves, thermal plasma, and dust in the vicinity of Saturn. Three nearly orthogonal electric field antennas…
