Introduction
Rosetta is an interplanetary spacecraft whose main objective is to rendezvous with Comet 67P/Churyumov-Gerasimenko. In order to investigate the comet nucleus and the gas and dust ejected from the nucleus as the comet approaches the Sun, Rosetta carries a suite of eleven instruments on the comet orbiter and Philae, a lander equipped with a further ten instruments which perform surface measurements. The orbiter instruments combine remote sensing techniques, such as cameras and radio science measurements, with direct sensing systems such as dust and particle analysers. The instruments are provided by collaborative efforts between scientific institutes in ESA member states and the USA. Principal investigators in different European countries and America lead the nationally funded collaborations. | Rosetta Orbiter Instruments | | Instrument | Principal Investigator | | ALICE | Ultraviolet Imaging Spectrometer | Alan Stern,
