The Martian surface radiation environment – a comparison of models and MSL/RAD measurements

Journal of Space Weather and Space Climate, 2016
Context: The Radiation Assessment Detector (RAD) on the Mars Science Laboratory (MSL) has been measuring the radiation environment on the surface of Mars since August 6th 2012. MSL-RAD is the first instrument to provide detailed information about charged

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 ...

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.

Catalytic/Protective Properties of Martian Minerals and Implications for Possible Origin of Life on Mars

Life, 2018
Minerals might have played critical roles for the origin and evolution of possible life forms on Mars. The study of the interactions between the “building blocks of life„ and minerals relevant to Mars mineralogy under conditions mimicking the

The Evolution of Autonomous Systems for Planetary Cave Exploration: A Review

Journal of Field Robotics, Volume 43, Issue 6, Page 4094-4115, September 2026.
ABSTRACT The exploration of Subsurface Access Points (SAPs), such as lava tubes on the Moon and Mars, has gained significant interest due to their potential as stable environments shielded from surface radiation and temperature extremes. These sites are considered high‐value targets for detecting water and signs of ancient life, and assessing their ...
