In situ observations of interstellar dust in the heliosphere by the Ulysses and Galileo satellites yield a different (by a factor of 4- 5) determination of the gas-to-dust mass ratio in the interstellar cloud surrounding the solar system than do remote astronomical observations by the Hubble Space Telescope. This paper grew out of discussions held at a series of workshops at the International Space Sciences Institute in 1997 and 1998.
