What did NASA find at the bottom of the ocean?

NASA's underwater discoveries focus on using space tech (like satellites and rovers) to map the ocean floor, find analogs for alien life on ocean worlds (like Europa), and develop deep-sea robots, revealing thousands of hidden seamounts, vast microbial ecosystems in basalt, and new volcanic activity, all while studying deep-sea resources and supporting missions like SWOT for better seafloor imaging, revealing a mysterious, life-filled deep ocean vital for Earth's climate.
 

How to tell if a beach has sand fleas?
