The ISSI international study team on the martian PBL – status report and plan [PDF]
, 2008 Dynamical processes in the Martian boundary layer provide the means of communication between surface ice deposits and the free atmosphere, and the means of lifting dust from the surface.

Geophysical Research Letters, 1979 During the Viking mission to Mars, the seismometer on Lander II collected approximately 0.24 Earth years of observational data, excluding periods of time dominated by wind‐induced Lander vibration. The “quiet‐time” data set contains no confirmed seismic events.

Hypogravity simulation using the Variable Gravity Suspension System: A technical report
Experimental Physiology, EarlyView.Abstract Human movement has evolved within Earth's gravitational environment (1 g; −9.81 m s−2). Future human exploration of terrestrial bodies, including the Moon (0.17 g; −1.62 m s−2) and Mars (0.38 g; −3.71 m s−2), will require astronauts to live and work within reduced gravitational environments (hypogravity).

New approaches to the exploration: planet Mars and bacterial life
, 2011 Planet Mars past environmental conditions were similar to the early Earth, but nowadays they are similar to those of a very cold desert, irradiated by intense solar UV light. However, some terrestrial lifeform showed the capability to adapt to very harsh

Scattering matrices and expansion coefficients of Martian analogue palagonite particles
, 2008 We present measurements of ratios of elements of the scattering matrix of Martian analogue palagonite particles for scattering angles ranging from 3 to 174 degrees and a wavelength of 632.8 nm.

On the Impact Origin of Phobos and Deimos I: Thermodynamic and Physical Aspects
, 2017 Phobos and Deimos are the two small moons of Mars. Recent works have shown that they can accrete within an impact-generated disk. However, the detailed structure and initial thermodynamic properties of the disk are poorly understood.

Improving the Accuracy of the Martian Ephemeris Short-Term Prediction
Advances in Astronomy, 2018 The Chinese Mars exploration mission is planned to be launched in 2020, which includes an orbiter, a lander, and a rover. High precision Martian ephemeris is very important in Mars exploration, especially for the Martian orbit insertion and the Martian ...

Martian north polar cap summer water cycle
, 2016 A key outstanding question in Martian science is 'are the polar caps gaining or losing mass and what are the implications for past, current and future climate?' To address this question, we use observations from the Compact Reconnaissance Imaging ...
