Demonstrating Martian gravity [PDF]
Physics Education, 2015 The surface gravity on Mars is smaller than the surface gravity on Earth, resulting in longer falling times. This effect can be simulated on Earth by taking advantage of air resistance and buoyancy, which cause low density objects to fall slowly enough to approximate objects falling on the surface of Mars.

A Thermal Plume Model for the Martian Convective Boundary Layer [PDF]
, 2013 The Martian Planetary Boundary Layer [PBL] is a crucial component of the Martian climate system. Global Climate Models [GCMs] and Mesoscale Models [MMs] lack the resolution to predict PBL mixing which is therefore parameterized.

Direct Formation of Structural Components Using a Martian Soil Simulant. [PDF]
, 2017 Martian habitats are ideally constructed using only locally available soils; extant attempts to process structural materials on Mars, however, generally require additives or calcination.

Planetary Bioresources and Astroecology 1. Planetary Microcosm Bioassays of Martian and Carbonaceous Chondrite Materials: Nutrients, Electrolyte Solutions, and Algal and Plant Responses [PDF]
, 2002 The biological fertilities of planetary materials can be assessed using microcosms based on materials in martian and carbonaceous chondrite meteorites.

Dune formation on the present Mars
, 2007 We apply a model for sand dunes to calculate formation of dunes on Mars under the present Martian atmospheric conditions. We find that different dune shapes as those imaged by Mars Global Surveyor could have been formed by the action of sand-moving winds

Martian atmospheric O3 retrieval development for the NOMAD-UVIS spectrometer [PDF]
, 2017 The composition of atmospheric trace gases and aerosols is a highly variable and poorly constrained component of the martian atmosphere, and by affecting martian climate and UV surface dose, represents a key parameter in the assessment of suitability for

Modeling the variations of Dose Rate measured by RAD during the first MSL Martian year: 2012-2014 [PDF]
, 2015 The Radiation Assessment Detector (RAD), on board Mars Science Laboratory's (MSL) rover Curiosity, measures the {energy spectra} of both energetic charged and neutral particles along with the radiation dose rate at the surface of Mars.

Martian meso/micro-scale winds and surface energy budget [PDF]
, 2011 Regional, diurnal and seasonal variations of surface temperature are particularly large on Mars. This is mostly due to the Martian surface remaining close to radiative equilibrium.

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.
