Polyextremophilic Bacteria in Al Wahbah Crater: A Terrestrial Model for Life On Enceladus
The study of extremophilic microorganisms has sparked interest in understanding extraterrestrial microbial life.
NASA’s SWIM Robot on Glacial Ice in Alaska
A model of a tiny, wedge-shaped robot designed to explore subsurface oceans of icy moons, right, sits beside a large waterproof capsule containing electronics and sensors for testing below glacial […]
NASA’s SWIM Submersible Droid Prototypes
Two prototypes for a NASA mission concept called SWIM (short for Sensing With Independent Micro-swimmers) are arranged beside a much smaller nonfunctioning model representing the final envisioned size of the […]
Tricorder Tech: Chemistry Modeling Software Used To Detect Conditions For Microbial Life On Icy Worlds
Southwest Research Institute is working to expand software normally used to model electrolytes and predict corrosion and turn it into a tool that can help determine whether ice-covered worlds have […]
Ocean Weather Systems On Icy Moons With Application To Enceladus
We explore ocean circulation on a rotating icy moon driven by temperature gradients imposed at its upper surface due to the suppression of the freezing point of water with pressure, […]
Dale Andersen’s Astrobiology Antarctic Status Report: 14 November 2024: The Plumes of Enceladus
Keith’s note: Astrobiologist Dale Andersen is back in Antarctica at Lake Untersee in October-December 2024 for another field season of research (preview). Dale’s work is coordinated through the SETI Institute. We’ll be posting […]
Distinguishing Potential Organic Biosignatures on Ocean Worlds from Abiotic Geochemical Products using Thermodynamic Calculations
The search for life in our solar system often involves efforts to detect organic molecules, which have been found on many extraterrestrial bodies, including planets, moons, meteorites, comets, and asteroids. […]
Modifications Of SPH Towards Three-dimensional Simulations Of An Icy Moon With Internal Ocean
There are some traces of the existence of internal ocean in some icy moons, such as the vapor plumes of Europa and Enceladus. This implies a region of liquid water […]
Sealing Europa’s Vents By Vapor Deposition: An Order Of Magnitude Study
Fractures and vents in the ice crust of Europa, exposing the sub-surface ocean to the vacuum, might be responsible for the generation of planetary-scale water-vapor plumes.
