Unveiling Hidden Microbial Diversity in Mars 2020 Mission Assembly Cleanrooms with Molecular Insights into the Persistent and Perseverance of Novel Species Defying Metagenome Sequencing
Due to strict cleaning procedures and nutrient-scarce conditions, aerospace industrial cleanrooms – which are essential for assembling space mission components – contain low microbial burdens but are tough to eradicate.
Planetary Protection: Extremophilic Bacteria Isolated from the NASA Phoenix Mission Spacecraft Assembly Cleanrooms
Human-designed oligotrophic environments, such as cleanrooms, harbor unique microbial communities shaped by selective pressures like temperature, humidity, nutrient availability, cleaning reagents, and radiation. During the Phoenix spacecraft mission, genomes of […]
Giant Viruses Have Been Found On Greenland’s Ice Sheet
Every spring when the sun rises in the Arctic after months of darkness, life returns. The polar bears pop up from their winter lairs, the arctic tern soar back from […]
Host-associated Phages Disperse Across The Extraterrestrial Analogue Antarctica
Extreme Antarctic conditions provide one of the closest analogues of extraterrestrial environments. Since air and snow samples, especially from polar regions, yield DNA amounts in the lower picogram range, binning […]
