Martian Golf Ball

open access: yes
This golf ball is designed to be used in Martian gravity. As Martian gravity is weaker than Earths, this golf ball feels heavy when held on Earth. It forms part of an ongoing project by Bethany Rigby on Golf and outer space, developing a speculative ...

Modern Challenges and Legal Innovations in Satellite Law [PDF]

open access: yesAdvanced Space Law
From the battlefields of Earth to the dusty plains of Mars, the law follows humanity into new frontiers. This research blends Martian – Martial Convergence – the interplay between Martian Law and Martial Law – with the introduction of the neologism ...

How to Search for Life in Martian Chemical Sediments and Their Fluid and Solid Inclusions Using Petrographic and Spectroscopic Methods

open access: yesFrontiers in Environmental Science, 2019
Abundant resources and efforts have been employed in the search for life on Mars. Satellites, landers, and rovers have tested atmospheric gases, general sediment and rock compositions, and images of Mars surface in an effort to detect biosignatures left ...

Tidal disruptions of rubble piles: The case of Phobos

open access: yesAstronomy & Astrophysics
Context. Many small satellites in the Solar System have sub-synchronous orbits, meaning their orbits are decaying due to tidal dissipation. Unless they have substantial material strength, they will eventually tidally disrupt before reaching their planet ...

A Simulation of Contact Graph Routing for Mars–Earth Data Communication

open access: yesAlgorithms
In this study, we develop a simulation of Contact Graph Routing (CGR) for data communication between Mars, Earth, and relay satellites. Due to the changing of the satellites’ distances to Mars and Earth, respectively, there are specific contact windows ...

Trajectory Design of Perseus: A CubeSat Mission Concept to Phobos

open access: yesAerospace, 2020
The Martian satellites Phobos and Deimos hold many unanswered questions that may provide clues to the origin of Mars. These moons are low Δv stopover sites to Mars.

Spontaneous Cyclic Levitation of Glycerol‐Water Droplets at Low Pressures

open access: yesAdvanced Science, EarlyView.
Under low pressure, a minute glycerol addition transforms the chaotic dynamics of freezing water droplets into cyclic levitation. Freeze‐concentration preserves liquid pathways that relax expansion‐induced stress, while freezing point depression weakens asymmetric vaporization recoil.

Computer modeling and experimental work on the astrobiological implications of the martian subsurface ionising radiation environment [PDF]

open access: yes, 2008
Any microbial life extant in the top meters of the martian subsurface is likely to be held dormant for long periods of time by the current permafrost conditions.

Water Electrolysis Technologies for Extraterrestrial Water Resource Conversion

open access: yesEcoEnergy, EarlyView.
This paper reviews four water electrolysis technologies for extraterrestrial water conversion: alkaline water electrolysis, proton exchange membrane water electrolysis, solid oxide water electrolysis, and anion exchange membrane water electrolysis. It elaborates on their mechanisms, components, and integration, highlighting challenges such as water ...
