COSIMA data analysis using multivariate techniques
Summary: COSIMA, an advanced TOF-SIMS instrument measuring the mass spectrum of dust grains collected at comet P67 by the ROSETTA spacecraft, is predicted to encounter complex mixtures of minerals and organic compounds. To extract information from this data set, we have developed a multivariate technique tested on laboratory measurements made by an identical instrument under controlled conditions. We have shown that minerals can be identified and separated with high level of confidence.

Image georectification and feature tracking toolbox: ImGRAFT
Summary: The use of time-lapse cameras is becoming an ever more popular method of observing changes in the natural environment. This study provides an overview of the newly developed Image GeoRectification And Feature Tracking toolbox (ImGRAFT). The paper outlines the main function of the toolbox and describes each of the key processes needed to transform a pair of terrestrial time-lapse images into a velocity field. The tool is presented using a case study of glacier surface motion at Engabreen, Norway.
Calibration of QM-MOURA three-axis magnetometer and gradiometer
Summary: In situ magnetometry is key for planetary mineralogy. However, since magnetic instrumentation is considered secondary in Mars and Moon landers and rovers, magnetometers have often very restricted envelopes of mass, volume and power, and consequently limited functionality.
In this work, it is presented the capability of MOURA small magnetometer and gradiometer to open a wide and novel scientific research on Mars mineralogy and paleomagnetism through the very complex calibration process.
