Earth’s biodiversity is increasingly threatened and at risk. We propose a passive lunar biorepository for long-term storage of prioritized taxa of live cryopreserved samples to safeguard Earth’s biodiversity and to […]
Planetary Protection & Biosafety
Simple Lipids Form Stable Higher-order Structures In Concentrated Sulfuric Acid
Venus has become a target of astrobiological interest because it is physically accessible to direct exploration, unlike exoplanets. So far this interest has been motivated not by the explicit expectation […]
Antioxidant Defense in the Toughest Animals on the Earth: Its Contribution to the Extreme Resistance of Tardigrades
Tardigrades are unique among animals in their resistance to dehydration, mainly due to anhydrobiosis and tun formation. They are also very resistant to high-energy radiation, low and high temperatures, low […]
Insights Into The Synthesis, Engineering, And Functions Of Microbial Pigments In Deinococcus Bacteria
The ability of Deinococcus bacteria to survive in harsh environments, such as high radiation, extreme temperature, and dryness, is mainly attributed to the generation of unique pigments, especially carotenoids.
Design, Development, And Operation Of An ISO Class 5 Cleanroom For Planetary Instrumentation And Planetary Protection Protocols
Cleanrooms are controlled environments where the number of airborne particles is reduced to a level defined by an International Organization for Standardization (ISO) standard. These facilities have applications in different […]
Microorganisms Can Travel Vast Distances In Earth’s Troposphere
Analysis of air samples taken at altitudes of up to 3,000 metres above Japan has revealed the presence of a vast range of viable bacteria and fungi transported by air […]
Science Community Virtual Workshop: MSR Sample Receiving Project Science Objectives
Date: Wednesday September 11, 9-11 am PDT/12 pm EDT/ 6 pm CEST
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 […]
Oxygen Produced In The Deep Sea Raises Questions About Extraterrestrial Life
Over 12,000 feet below the surface of the sea, in a region of the Pacific Ocean known as the Clarion-Clipperton Zone (CCZ), million-year-old rocks cover the seafloor. These rocks may […]
Call for Abstracts: NASA SMD Virtual Workshop on Planetary Protection
Our second Science Mission Directorate virtual event, a three-day workshop, will take place from October 30th – November 1st. We are currently accepting abstracts from the community to introduce mission […]
