What is the most critical creature on Earth? Hint: It is invisible to the naked eye; 99% of the people never heard about it; 200 years ago we didn't even know it existed, yet it produces over 50% of the Earth's oxygen. Despite being invisible, it can be seen from space! For this reason, NASA just put into orbit a new satellite specifically dedicated to this creature: phytoplankton. Join the conversation with an award-winning NASA and Harvard scientist on how we can see the invisible by leveraging breakthrough space technology and AI.
