Dry Downhill Particle Motion on Mars
The Planetary Science JournalWe recently flew a new setup on parabolic flights for the first time to study particle motion on Martian slopes under Martian gravity. Here, we describe the initial experiments. We used dust/sand beds at varying ambient pressure of a few hundred pascals.

Attitudes towards Autonomous Data Collection and Analysis in the Planetary Science Community
Galaxies, 2013 As missions are planned to targets further away from Earth, it becomes all but required to increase the role of autonomy in the mission. An investigation of what aspects of mission operations and decision making autonomy will be accepted in by the ...

Advanced Functional Materials, EarlyView.The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.

Long Period Seismology on Titan in the Presence of a Methane Clathrate Lid
Earth and Space SciencePrevious 1‐D spherically symmetric seismic modeling studies have shown that in the presence of a clathrate lid on Titan significant thermal profile differences result, particularly in comparison to a pure water ice shell.
