Clues to the formation and early history of the terrestrial planets are locked in the abundances of noble gases and their isotopes on Venus. The abundances of xenon, krypton and other tracers of Venus's past await in-situ atmospheric sampling by a future mission, such as by a probe or balloon-borne science station, depicted on the right.
