Spaceflight and sport science: Physiological monitoring and countermeasures for the astronaut–athlete on Mars exploration missions

Experimental Physiology, EarlyView.
Abstract Long‐duration spaceflight impacts essentially every system in the human body, resulting in multisystem deconditioning that might impair the health and performance of crewmembers, particularly on long‐duration exploration missions to Mars. In this review, we apply the sport science model of athlete monitoring, testing and training to astronauts;

A new model describing Forbush Decreases at Mars: combining the heliospheric modulation and the atmospheric influence

Earth and Planetary Physics, 2020
Forbush decreases are depressions in the galactic cosmic rays (GCRs) that are caused primarily by modulations of interplanetary coronal mass ejections (ICMEs) but also occasionally by stream/corotating interaction regions (SIRs/CIRs).

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 ...

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

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.

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 ...

Super‐Resolution of Planetary Images Based on Generative Adversarial Network

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Currently, satellite imagery serves as the primary means of observing terrestrial planets such as the Mars, the Moon, and Mercury. Enhancing the resolution and quality of these images can provide more detailed insights into planetary surfaces. However, improvements in image quality are often limited by the constraints of sensor technology and ...

Alteration of a Mantle‐Derived Dunite Boulder in Jezero Crater, Mars

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract In 2023, the Mars 2020 Perseverance rover explored the youngest preserved deposits on the Western fan of Jezero crater, Mars: a field of meter‐scale boulders dispersed above the previously explored sandstone and siltstone units. Reflectance spectra of the boulders delineated two classes, one olivine‐bearing and one pyroxene‐bearing.

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

ALERA‐V Version 1.0: An Objective Analysis Dataset of the Venus Atmosphere

Geoscience Data Journal, Volume 13, Issue 3, July 2026.
Using observations from the Venus orbiter Akatsuki, we present the first objective analysis dataset of the Venus atmosphere. ALERA‐V, generated with the ALEDAS‐V system using the LETKF, is expected to support studies of atmospheric dynamics and the planning of future satellite missions.
