GALILEO DUST DETECTION SYSTEM (GDDS) Data Set Version 2.0 - Reviewed Mar 9, 1999

In December 1989, two months after the launch of Galileo, the Dust Detection System began its ongoing mission to directly measure the dust environment of interplanetary space and around Jupiter. GDDS works by detecting the charged plasma that results when a dust particle impacts the instrument at hypervelocites. From these measurements, particle mass, speed and direction can be constrained. GDDS can identify particles having masses between 10^-16g and 10^-6g traveling at relative speeds of up to 70 km/s. GDDS has detected interplanetary dust from asteroids and comets, interstellar dust, and streams of dust originating from Io volcanic activity.
