CoCa
The Comet Comera (CoCa) is the imaging system on Comet Interceptor's primary spacecraft and is provided by a consortium led by the University of Bern. It is designed to provide high resolution imaging of the nucleus of the selected comet in four filters at selected broadband optical wavelengths. CoCa is based on the stereographic camera Colour and Stereo Surface Imaging System (CaSSIS) on the ExoMars Trace Gas Orbiter mission to Mars, which was also developed at the University of Bern. The system is constructed to provide over 2500 images during the fly-by and can allow saturation on the nucleus to provide optimum signal-to-noise on the dust coma at all times through the fly-by.
MANiaC
The Mass Analyzer for Neutrals in a Coma (MANiaC) instrument, also located on the primary spacecraft, is made up of a time-of-flight mass spectrometer and a neutral density gauge, both attached to an electronics unit. The combination of the two sensors enables measurements of the absolute neutral gas densitites of different volatile species along the fly-by trajectory of the Comet Interceptor spacecraft. MANiaC is set to measure the abundances of the major volatile species in the cometary coma (atoms, molecules and small ice particles), their mass and chemical make-up, and may also be able to measure minor species such as organic molecules and optain information on the composition of dust grains.
