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.

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.

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.

We present a new instrument for measuring surface runoff rates ranging from very low (~0.05L min-1) to high (300L min-1, with much higher rates possible depending on the device configuration). The device is economical, simple, rugged, accurate and requires little maintenance (the system is self-emptying and contains no moving parts). We have successfully used this instrument in long-term monitoring studies and expect that it will appeal to other scientists studying runoff processes.

This paper discussed the effect of temperature on the accuracy of submersible strain gauge pressure transducers. The results show that rapid change of temperature introduces errors in the water level reading while the absolute temperature is also related to the sensor errors. The former is attributed to venting and the latter is attributed to temperature compensation effects in the strain gauges. Performance tests are necessary before field deployment to ensure the data quality.

We present the high-frequency properties of the eight electric field sensors as proposed to be launched on the spacecraft “RESONANCE” in the near future. Due to the close proximity of the conducting spacecraft body, the sensors (antennas) have complex receiving features and need to be well understood for an optimal mission and spacecraft design. In particular techniques like wave polarization analysis and incident direction finding depend crucially on the presented antenna characteristics.

The PICARD Bolometric Oscillation Sensor experiment was the first experiment to simultaneously measure the solar and terrestrial radiation with a single detector. It is a powerful tool for exploring thermal properties of a planetary body. The sensor has high repeatability due to its simplified design. Thus, it has the potential to payload on several microsatellites or even CubeSats and form a consultation array to track small energy exchange of the planet.

Seafloor drill rigs are remotely operated systems that provide a cost-effective means to recover sedimentary records of the upper sub-seafloor deposits. Recent increases in their payload included downhole logging tools or autoclave coring systems. Here we report on another milestone in using seafloor rigs: the development and installation of shallow borehole observatories for the MARUM-MeBo seafloor drill developed at University of Bremen, Germany.

We present a new real-time experimental setup for analysing in continuum radon emissions over variable stress-strain regimes. The setup consists of a radon accumulation chamber that can host large cylindrical rock samples and is connected to a RAD7 radon monitor. The radon signal is enhanced using a heating system. The accumulation chamber is then placed into a uniaxial testing apparatus that allows obtaining a variety of deformation conditions.

Multiobjective optimization is used to design Pareto optimal greenhouse gas (GHG) observing networks. A prototype GHG network is designed to optimize scientific performance and measurement costs. The Pareto frontier is convex, showing the trade-offs between performance and cost and the diminishing returns in trading one for the other. Other objectives and constraints that are important in the design of practical GHG monitoring networks can be incorporated into our method.
