Rosetta lander instruments

The Rosetta lander has many instruments that it will use to make measurements when it lands on Comet Churyumov-Gerasimenko. The instruments carried by the lander are described in the table below. The instruments on the Rosetta orbiter are described on a separate page.

Instrument Purpose
ALICE Analyzes gases in comet's coma and tail
CONSERT Uses radio waves to probe comet's interior
COSIMA Chemical analysis of dust grains
GIADA Dust velocity and impact measurement - number, masses, and velocities of dust grains coming from the comet
MIDAS Micro-imaging dust analysis - physical analysis (size, shape, etc.) of dust grains
MIRO Measures major gases and sub-surface temperature of the comet
OSIRIS Wide-angle and narrow-angle cameras
ROSINA Chemical analysis of comet's atmosphere
RPC Plasma measurements - 5 sensors measure physical properties of the nucleus, the structure of the coma, and the comet's interaction with the solar wind
RSI Spacecraft's radio signals are used to measure the mass & density of the nucleus and to define the comet's orbit
VIRTIS Maps the temperature on the surface of the nucleus & identifies gases
