Voyager 2 was one of a pair of spacecraft launched to explore the planets of the outer solar system and the interplanetary environment: Each Voyager had as its major objectives at each planet to: (1) investigate the circulation, dynamics, structure, and composition of the planet's atmosphere; (2) characterize the morphology, geology, and physical state of the satellites of the planet; (3) provide improved values for the mass, size, and shape of the planet, its satellites, and any rings; and (4) determine the magnetic field structure and characterize the composition and distribution of energetic trapped particles and plasma therein.

"The atmosphere of Uranus is composed of 83% hydrogen, 15% helium, 2% methane and small amounts of acetylene and other hydrocarbons." (Hamilton, 2003)
