The Rosetta lander
The 100-kilogram Rosetta lander is provided by a European consortium under the leadership of the German Aerospace Research Institute (DLR). Other members of the consortium are ESA and institutes from Austria, Finland, France, Hungary, Ireland, Italy and the UK.
ALICE
ALICE (Ultraviolet Imaging Spectrometer) analyses gases in the coma and tail and measures the comet's production rates of water and carbon monoxide/dioxide. It also provides information on the surface composition of the nucleus.
CONSERT
CONSERT (Comet Nucleus Sounding Experiment by Radiowave Transmission) probes the comet's interior by studying radio waves that are reflected and scattered by the nucleus.
