A Spectroscopic Tour of the Solar System with FUSE

Paul Feldman

The spectral band, resolution, and sensitivity of the Far Ultraviolet Spectroscopic Explorer satellite, launched in June 1999, provide a unique capability to study the principal atoms, ions and molecules in a variety of planetary environments. The wavelength region from 905 to 1187 A, which is rich in emissions of H2 and CO as well as many ionic species, is observed at a spectral resolution of 0.3 A or less. This talk will describe recent observations and results on the atmospheres of Earth and Mars, polar aurora on Jupiter and Saturn, the Io plasma torus, and cometary comae.
