Scientific paper

We propose to observe with the planetary camera (PC) of HST the short-period comet P/Faye at its closest approach to the Earth (0.6 AU). The high spatial resolution (40 km) over a large field will allow to image the dust and gas jets "down to the nucleus" and to follow their temporal evolution over a period of approximately 10 days. Combined with ground-based observations as a model of the dust/gas expansion, it will be possible to map the discrete sources of emission on the nucleus and study its rotational properties. HST will extend the present insight we have of comet Halley to another comet, an important step in the current exploration and understanding of primitive bodies in the solar system.
