Similar instruments to the Dust Flux Monitor Instrument (DFMI) developed by the University of Chicago have flown on other missions, including the former Soviet Union's Vega missions to Comet Halley in 1986, the ERIS Observer instrument; the Space Dust (SPADUS) instrument for the Advanced Research and Global Observation Satellite (ATGOS) in Earth orbit, and the High Rate Detector (HRD) on the Cassini mission to Saturn launched in 1997.

The Cassini instrument will study the mass distribution of particle fluxes during a four-year orbital tour of Saturn's ring system and conduct measurements during the Jupiter flyby. A similar instrument is being considered for other NASA missions.

These instruments make exclusive use of the polyvinylidene fluoride (PVDF) dust sensor developed at University of Chicago's Laboratory for Astrophysics and Space Research of the Enrico Fermi Institute. Professor John Simpson and Dr. Anthony Tuzzolino, Stardust's Principle Investigator for the DFMI, have spent almost two decades focused on developing instruments for dust particle measurement in space. Dr. Tuzzolino,a Senior Scientist at the laboratory, is also Co-Investigator for the Cassini Mission's Cosmic Dust Analyzer.
