The atmosphere is composed of molecular oxygen gas O 2 produced when ultraviolet light from the Sun interacts with water ice in the rings. Two small saucer-shaped moons, Pan and Atlas, have ridges along their equators. But the Saturn V just sat there. Olaf's diagrams are an insightful resource and they can also help to illustrate those areas of planetary research which are currently being neglected such as the Uranian and Neptunian systems and prominent asteroids such as Pallas, Hygiea, Euphrosyne, Europa and Interamnia, for example.

Maize said there is a small chance Cassini could run out of rocket fuel before Sept. Farther out is the G ring, and finally the E ring, which is made up of very fine almost microscopic particles.

Nature Geoscience. Earlier Voyager observations of density waves in the A and B rings and an optical depth profile had yielded a mass of about 0. Nevertheless, the Cassini imaging team kept looking for spokes in images of the rings, and they were next seen in images taken on 5 September People were surprised to learn that the various stages had never seen each other until they were introduced in the VAB drydock.
