Featured Missions & Projects - Planetary Magnetospheres Laboratory (695)
The objective of the RPWS investigation is to study radio and plasma waves in the vicinity of Saturn and during the flight to Saturn. This objective includes studies of radio emissions, plasma waves, lightning, dust impacts, plasma densities and temperatures, and plasma density fluctuations. Regions investigated include Saturn's magnetosphere; Titan's ionosphere; the solar wind; Jupiter's magnetosphere; and Earth, Venus, and the asteroids.
The Autonomic NanoTechnology Swarm (ANTS) is a generic mission architecture consisting of miniaturized, autonomous, self-similar, reconfigurable, addressable components forming structures. The components/structures have wide spatial distribution and multi-level organization.
The Gamma-Ray and Neutron Spectrometer (GRNS) is an instrument aboard the MESSENGER spacecraft, a NASA mission to conduct the first orbital study of Mercury. The purpose of the GRNS is to provide information about the elements that make up Mercury's surface crust. More exactly, it will provide information about the uppermost tens of centimeters of the crust. This instrument measures the numbers and energies of gamma rays and neutrons that reach the MESSENGER probe as it passes near the planet.
The URAP experiment provides electric field measurements from "DC" to 1 MHz and magnetic field measurements from 0.22 to 450 Hz. These bandwidths permit the study of radio emissions from solar ejecta, interplanetary transients, and planetary magnetospheres and of in situ plasma waves associated with interplanetary shocks, coronal mass ejections, and other transients. The radio observations provide an important remote diagnostic of solar flares and shocks. The plasma wave observations are critical to the understanding of instabilities that exist throughout the interplanetary medium (IPM). Furthermore, analyses of the URAP data permit deriving fundamental characteristics of the solar wind, such as electron density and temperature.
