Effects of Low-Temperature Plasma-Sterilization on Mars Analog Soil Samples Mixed with Deinococcus radiodurans

Life, 2016
We used Ar plasma-sterilization at a temperature below 80 °C to examine its effects on the viability of microorganisms when intermixed with tested soil.

Crater Observing Bioinspired Rolling Articulator (COBRA)

Advanced Intelligent Systems, EarlyView.
Crater Observing Bio‐inspired Rolling Articulator (COBRA) is a modular, snake‐inspired robot that addresses the mobility challenges of extraterrestrial exploration sites such as Shackleton Crater. Incorporating snake‐like gaits and tumbling locomotion, COBRA navigates both uneven surfaces and steep crater walls.

Numerical Simulations of the Lunar Penetrating Radar and Investigations of the Geological Structures of the Lunar Regolith Layer at the Chang’E 3 Landing Site

International Journal of Antennas and Propagation, 2017
In the process of lunar exploration, and specifically when studying lunar surface structure and thickness, the established lunar regolith model is usually a uniform and ideal structural model, which is not well-suited to describe the real structure of ...

The Effect of Tip Design on Technological Performance During the Exploration of Earth, Lunar, and Martian Soil Environments

Journal of Field Robotics, EarlyView.
ABSTRACT This paper investigates the penetration performance of soil‐burrowing probes with different tip designs during shallow‐depth penetration in various media, including terrestrial soils (Hostun sand) and well‐characterized planetary soil simulants (LHS‐1 Lunar regolith simulant and MGS‐1 Martian regolith simulant).

Investigation of the melting behavior of laser-melted lunar regolith simulant for in-situ construction

Journal of Materials Research and Technology
Additive manufacturing of lunar regolith is one of the most promising methods for lunar surface construction. In order to obtain excellent formability of lunar regolith, the interaction between laser and lunar regolith has to be studied in detail.

Evidence of Potential Organo-Mineral Interactions during the First Stage of Mars Terraforming

Soil Systems, 2023
Future space missions to Mars will depend on the development of bioregenerative life support systems. Mars regolith contains most of the nutrients needed for plant growth, but not organic matter (OM).

Accessing and assessing lunar resources with PROSPECT [PDF]

, 2014
PROSPECT is a package in development by ESA to assess the in-situ resource potential of lunar regolith. PROSPECT will: obtain sub-surface regolith samples, extract volatiles, identify chemical species, quantify abundances, and characterize ...

Petrography of phosphates in CI and CY carbonaceous chondrites

Meteoritics &Planetary Science, EarlyView.
Abstract Phosphate minerals are significant carriers of volatiles (e.g., OH) and halogens in chondritic material; however, their origin in most groups of carbonaceous chondrites remains poorly characterized. We have determined the abundance, morphology, texture, and composition of phosphate grains in aqueously altered CI chondrites and in hydrated and ...

Scaling forces to asteroid surfaces: The role of cohesion

, 2010
The scaling of physical forces to the extremely low ambient gravitational acceleration regimes found on the surfaces of small asteroids is performed. Resulting from this, it is found that van der Waals cohesive forces between regolith grains on asteroid ...
