ULYSSES DUST DETECTION SYSTEM (UDDS) Data Set Version 2.0 - Reviewed Mar 9, 1999

In October 1990, three weeks after the launch of Ulysses, the Dust Detection System began its ongoing mission to directly measure the dust environment of the inner solar system, from Venus to Jupiter, and particularly at high solar latitudes. UDDS 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. UDDS 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.
