Summary

The ExoMars rover will launch in 2020, with the aim of looking for evidence of extinct life on Mars. This project will combine laboratory, remote sensing and field studies to help different ExoMars instruments prepare for the surface mission. The overall goal is to determine the geology of Mars from both orbital and rover data, with particular emphasis on developing techniques that will maximise the rover science return.

Description

The key science objectives of the ExoMars rover, that will launch in 2020, are to:
(1) search for signs of past and present life on Mars;
(2) investigate the water/geochemical environment as a function of depth in the shallow subsurface (Vago et al., 2017).

On board the rover is a suite of instruments that will be used to first identify suitable geological targets for in situ investigation. A deep drill core will then be obtained and returned to the rover analytical laboratory, to look for indicators of past life using complementary techniques including assessment of morphology (potential fossil organisms), mineralogy (past environments and water-rock reaction) and organic molecules and other biomarkers.

An important part of preparing for the ExoMars mission is to understand the data that will be returned, not only in terms of improving processing techniques and maximising the science return, but also in determining the possible limitations of different approaches. Fundamental to this task is being able to relate the vast quantities of orbital data with any rover data from the surface, in addition to exploring the type of data that will be returned.

As part of the preparation for the ExoMars 2020 mission, this project will use a range of different techniques and approaches to
(1) help validate interpretations and hypotheses made from orbital data, previous surface rover missions and fieldwork, and
(2) use ExoMars instrument emulators to test the capability of different observation techniques.

The results will be important for landing site interpretation and mission planning when on the surface, but also of particular relevance to the ExoMars PanCam (Coates et al., 2017), ISEM (Korablev et al., 2017), CLUPI (Josset et al., 2017), and MicrOmega (Bibring et al., 2017) instruments. Therefore, the objectives of this project are to help determine the geology of Mars with orbital and rover data, specifically:

(1) Conduct visible and near-infrared analyses of martian meteorites to determine the spectral response of different instruments.
(2) Compare and contrast geological interpretations of the martian surface from orbital and rover data.
(3) Determine the difference between field-based observations and interpretations from a human with that expected with ExoMars.

This project will use techniques from different disciplines, providing the student with training in the use of GIS software (e.g. ArcGIS, ENVI, SocetSet), analytical facilities (e.g. near-infrared spectrometers, CT scanners), with the potential for geological fieldwork in the UK and overseas.

The project will use the world-class meteorite collection at the Natural History Museum, London, and would suit an enthusiastic individual with a background in geosciences in general, and geology and/or planetary science in particular.
