I am Project Manager for the Comet Camera (CoCa), the imaging system on ESA's future Comet Interceptor mission. This goal of this mission is to send a spacecraft to a, yet unselected, long-period comet, or interstellar object, intercepting it as it passes close to the inner solar system. The CoCa instrument will provide high resolution imaging of the nucleus of the selected comet in 4 filters at specific broadband optical wavelengths. To provide high performance at low cost, it relies on designs successfully developed for previous flight programs, such as CaSSIS (see below). During a 1000 km fly-by, CoCa will provide 8 m per pixel images at a repetition frequency of 1 image per second. CoCa will therefore provide the highest quality imaging of the surface and the dust in the near-nucleus environment over a range of phase angles. Check out the Comet Interceptor website for more details.
In addition, I am part of the science teams of two remote sensing instruments in orbit around Mars: The University of Arizona's High Resolution Imaging Science Experiment (HiRISE) on board NASA's Mars Reconnaissance Orbiter (MRO), and The University of Bern's Colour and Stereo Surface Imaging System (CaSSIS) on board ESA's ExoMars Trace Gas Orbiter (TGO). Both instruments are taking spectacular images of the red planet, which the scientific community can then use to understand the history and current state of Mars, and its connection to solar system history.
CaSSIS reveals the beautiful sedimentary beds of a mound in Juventae Chasma, just north of Vallis Marineris near the Martian equator. Similarly to the Polar Layered Deposits, sedimentary deposits like these also record variations in climate or environmental properties that led to the accumulation of individual layers, but at much more ancient times than the polar record. This mound has been found by other instruments to contain sulfates, which are minerals that indicate the past presence of water.
You can follow the operations and see many of the images taken by these instruments through our Instagram (@uahirise and @cassis_unibe) and Twitter (@HiRISE and @ExoMars_CaSSIS) accounts.
