Crop growth and viability of seeds on Mars and Moon soil simulants

open access: yesOpen Agriculture, 2019
If humans are going to establish a base on the Moon or on Mars they will have to grow their own crops. An option is to use Lunar and Martian regolith. These regoliths are not available for plant growth experiments, therefore NASA has developed regolith ...

Investigating Terrestrial and Extraterrestrial Bioremediation through Microbial Action Using Raman Spectroscopy

open access: yesChallenges
Sodium perchlorate is a toxic salt-based compound found both terrestrially, (due to pollution) and extraterrestrially on the surface of Mars. Perchlorate pollution poses a risk to agricultural-based activities as once it enters soils/waterways it can be ...

Establishment of the Coast Range ophiolite microbial observatory (CROMO): drilling objectives and preliminary outcomes [PDF]

open access: yesScientific Drilling, 2013
This project aimed to establish a subsurface microbial observatory in ultramafic rocks, by drilling into an actively serpentinizing peridotite body, characterizing cored rocks, and outfitting the boreholes for a program of long-term observation and ...

Methanogens Through Time and Space: Impact on Earth’s Planetary Evolution and Biogeochemistry

open access: yesGeosciences
Methanogens, or methanogenic archaea (MA), are among the most ancient and widely distributed microorganisms, characterized by a unique metabolism that generates methane (CH4) as the terminal product of anaerobic respiration.
