Constraints on Martian Chronology from Meteorites

Geosciences, 2020
Martian meteorites provide the only direct constraints on the timing of Martian accretion, core formation, magmatic differentiation, and ongoing volcanism. While many radiogenic isotope chronometers have been applied to a wide variety of Martian samples,

Jumping on the moon as a potential exercise countermeasure

Experimental Physiology, EarlyView.
Abstract The Moon's gravitational field strength (17% Earth's gravity) may facilitate the use of bodyweight jumping as an exercise countermeasure against musculoskeletal and cardiovascular deconditioning in reduced gravity settings. The present study characterised the acute physiological and kinetic responses to bodyweight jumping in simulated Lunar ...

Identifying and Interpreting Stratification in Sedimentary Rocks on Mars: Insight from Rover and Orbital Observations and Terrestrial Field Analogs [PDF]

, 2013
Sedimentary rocks on Mars provide insight into past aqueous and atmospheric processes, climate regimes, and potential habitability. The stratigraphic architecture of sedimentary rocks on Mars is similar to that of Earth, indicating that the processes ...

POD-Galerkin modelling of the Martian atmosphere

, 1999
The aim of this thesis is to seek a low-dimensional description of baroclinic instability in general, and of the Martian atmosphere in particular, where both forcing and spatial resonance are relevant to the dynamics of the system being analysed.

Review for the Design and Experimental Study of a Coaxial Twin-rotor Mars Unmanned Aerial Vehicle

Space: Science & Technology
The thin atmosphere of Mars presents a necessary yet challenging flight environment for low-altitude flying vehicles or unmanned aerial vehicles. As a key technology, Martian unmanned aerial vehicles hold marked value and importance for scientific ...

Semantic Segmentation of Martian Landforms with Sparse Scribble Annotations Using a Pseudo-Labeling Strategy [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Deep learning-based semantic segmentation techniques play a crucial role in the rapid mapping of Martian landforms. However, creating an annotated dataset for Martian landforms is a labor-intensive and time-consuming process.

Hyper‐buoyancy flotation increases cervical disc height and reduces vertebral stiffness, with only partial reversal after acute 1 g axial loading

Experimental Physiology, EarlyView.
Abstract Exposure to microgravity is associated with stature increases, moderate‐to‐severe back/neck pain and elevated lumbar and cervical intervertebral disc (IVD) herniation risk post‐flight. Whilst lumbar pathophysiology has been investigated, little attention has been placed on the cervical spine.

Perchlorates on Mars enhance the bacteriocidal effects of UV light

Scientific Reports, 2017
Perchlorates have been identified on the surface of Mars. This has prompted speculation of what their influence would be on habitability. We show that when irradiated with a simulated Martian UV flux, perchlorates become bacteriocidal.

Jumping in simulated lunar gravity with blood flow restriction as a potential exercise countermeasure: The acute physiological effects

Experimental Physiology, EarlyView.
Abstract The present study examined the cardiovascular, metabolic, neuromuscular and perceptual effects of low‐intensity jumping in simulated lunar gravity (∼20% bodyweight) with blood flow restriction (BFR). Fourteen healthy adults (24 ± 4 years; 1.81 ± 0.06 m; 75 ± 12 kg) completed an incremental jumping test in simulated lunar gravity (9.5° head‐up ...
