Abstract

Neutral oxygen in the saturnian system shows variability, and the total number of oxygen atoms peaks at 4 x 10/34. Saturn´s aurora brithtens in response to solar-wind forcing, and the auroal spectrum resembles Jupiter´s. Phoebe´s surface shows variable water-ice content, and the data indicate it originated in the outer solar system. Saturn´s rings also show variable water abundance, with the purest ice in the outermost A ring. This radial variation is consistent with initially pure water ice bombarded by meteors, but smaller radial structures may indicate collisional transport and recent renewal events in the past 10/7 tp 10/8 years.
