A search for life on Earth from the Galileo spacecraft
- C. Sagan, W. R. Thompson, R. Carlson, D. Gurnett, C. Hord
- Physics, Medicine
- Nature
- 21 October 1993
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… Expand
An update to a Saturnian longitude system based on kilometric radio emissions
- W. Kurth, T. Averkamp, D. Gurnett, J. Groene, A. Lecacheux
- Physics, Geology
- 1 May 2008
[1] 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… Expand
In Situ Observations of Interstellar Plasma with Voyager 1
- D. Gurnett, W. Kurth, L. Burlaga, N. Ness
- Materials Science, Medicine
- Science
- 27 September 2013
Finally Out Last summer, it was not clear if the Voyager 1 spacecraft had finally crossed the heliopause—the boundary between the heliosphere and interstellar space. Gurnett et al. (p. 1489,… Expand
The Earth as a radio source: Terrestrial kilometric radiation
- D. Gurnett
- Geology
- 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… Expand
Spatio-temporal structure of storm-time chorus
- O. Santolík, D. Gurnett, J. Pickett, M. Parrot, N. Cornilleau-Wehrlin
- Physics
- 1 July 2003
[1] 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… Expand
Discovery of a north-south asymmetry in Saturn's radio rotation period
- D. Gurnett, A. Lecacheux, +5 authors J. Carbary
- Physics
- 1 August 2009
[1] For many years it has been known that Saturn emits intense radio emissions at kilometer wavelengths and that this radiation is modulated by the rotation of the planet at a rate that varies by up… Expand
The reversal of the rotational modulation rates of the north and south components of Saturn kilometric radiation near equinox
- D. Gurnett, J. Groene, +5 authors A. Lecacheux
- Physics, Geology
- 1 December 2010
[1] It has been known for many years that Saturn emits intense radio emissions at kilometer wavelengths and that this radiation is modulated by the rotation of the planet at a rate that varies slowly… Expand
CRRES plasma wave experiment
- R. Anderson, D. Gurnett, D. Odem
- Physics
- 1 August 1992
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… Expand
The Variable Rotation Period of the Inner Region of Saturn's Plasma Disk
- D. Gurnett, A. Persoon, +4 authors D. Southwood
- Physics, Medicine
- Science
- 20 April 2007
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… Expand
Titan's magnetospheric interaction
- F. Neubauer, D. Gurnett, J. Scudder, R. Hartle
- Physics
- 1 December 2007
Voyager 1 encounter data are used to theoretically examine the interaction of Titan with the solar wind, the Saturn magnetosheath and the Saturn magnetosphere. The spacecraft data comprised… Expand
