This is the ground support equipment from the DUCMA (Dust Counter and Mass Analyzer) instrument. The DUCMA was designed to measure the masses and fluxes of impacting dust particles. The instrument flew onboard the Vega spacecraft that flew by the comet Halley in March 1986. The DUCMA used a polarized polymer film to detect particle impacts and measure the particle’s mass and velocity. A second detector collected acoustic information from the impacts. The Vega encounters with comet Halley allowed the first direct measurements of the dust particles originating from the nucleus of a comet.
NASA transferred this equipment to the Museum in 1992.
