For this special episode of STEM-Talk, IHMC Research Scientist and STEM-Talk Host Dawn Kernagis sits on the other side of the microphone. This summer, Dawn was one of six divers selected for NASA’s NEEMO (NASA Extreme Environment Mission Operations) 21 mission, and we were able to talk to her live from the Aquarius Reef Base, located 62 feet below the surface of the Atlantic Ocean in the Florida Keys National Marine Sanctuary.

During the 16-day mission, Dawn and her colleagues performed field research designed to test operations and equipment for future space exploration. In particular, the international crew of aquanauts performed research both inside and outside the habitat. During simulated spacewalks carried out underwater, they evaluated tools and mission operation techniques that could be used in future space missions. Inside the habitat, the crew’s objectives include testing a DNA sequencer, a medical telemetry device, and HoloLens operational performance for human spaceflight cargo transfer.

In many ways, the NEEMO mission crystalizes Dawn’s career. Her research expertise has been focused on human performance, risk mitigation and resilience in extreme environments—namely undersea and in space. In addition to her accomplishments as a scientist, Dawn is also a long-standing diver, and this year was inducted into the Women Divers Hall of Fame.

Conducting the interview is IHMC Senior Research Scientist and former NASA astronaut Tom Jones. Dawn shares aspects of her daily life in the undersea habitat, from eating freeze dried food to watching thousands of fish from the galley window every night before bed. She also delves into the research that she conducted, which included testing a mini DNA sequencer and deep water dives to collect samples of several coral species and weighted walks on the ocean floor to simulate space walks.

STEM-Talk’s Billy Howell and Jason Conrad, key players in the production of each episode, also join the impromptu conversation with “fanboy” questions for Dawn.
