  We describe our ongoing work on, and future plans for, searches in bulk
matter for fractional charge elementary particles and very massive elementary
particles. Our primary interest is in searching for such particles that may
have been produced in the early universe and may be found in the more primeval
matter available in the solar system: meteorites, material from the moon's
surface, and certain types of ancient terrestrial rocks. In the future we are
interested in examining material brought back by sample return probes from
asteroids. We will describe our experimental methods that are based on new
modifications of the Millikan liquid drop technique and modern technology:
micromachining, CCD cameras, and desktop computers. Extensions of our
experimental methods and technology allow searches for very massive charged
particles in primeval matter; particles with masses greater than 10**13 GeV. In
the first such searches carried out on earth there will be uncertainties in the
mass search range. Therefore we will also discuss the advantages of eventually
carrying out such searches directly on an asteroid.
