Newly Discovered Hydrothermal Vents At Depths Of 3,000 Meters Off Svalbard

by Keith Cowing

Hydrothermal vents are seeps on the sea floor from which hot liquids escape. “Water penetrates into the ocean floor where it is heated by magma. The overheated water then rises […]

Sustaining Hydrothermal Circulation With Gravity Relevant to Ocean Worlds

by Keith Cowing

Some ocean worlds may sustain active, seafloor hydrothermal systems, but the characteristics and controls on fluid-heat transport in these systems are not well understood.

Hydrothermal Vents On The Seafloors Of Ocean Worlds Could Support Life

by Keith Cowing

We’ve all seen the surreal footage in nature documentaries showing hydrothermal vents on the frigid ocean floor—bellowing black plumes of super-hot water—and the life forms that cling to them. Now, […]

AI in Space for Scientific Missions: Strategies for Minimizing Neural-Network Model Upload

by Keith Cowing

Artificial Intelligence (AI) has the potential to revolutionize space exploration by delegating several spacecraft decisions to an onboard AI instead of relying on ground control and predefined procedures.
