In this special episode of Talking Space, we delve into a rarely discussed, but crucial aspect of living in space: health and sickness. We're putting the spotlight on the unique challenges posed by bacterial and viral infections aboard the International Space Station (ISS) and future long-duration missions.

We're bringing you a deep dive into a groundbreaking experiment, GEARS (Genomic Enumeration of Antibiotic Resistance in Space), recently transported to the ISS. What is the aim of this experiment? How can analyzing the genetic makeup of antibiotic-resistant microbes in space help us on Earth?

Joining us for this insightful conversation are Dr. Sarah Wallace, a NASA microbiologist at the Johnson Space Center’s Biomedical research and Environmental Sciences Division Microbiology Laboratory, and Dr. Christopher Carr, co-director of the Georgia Tech Astrobiology Program. They'll shed light on the history of sickness on the ISS, the precautions in place, and the worst-case scenarios of illness or injury that have occurred.

How do astronauts maintain personal hygiene in space? What kind of medical supplies are available aboard the ISS? Tune in to find out.

We're also discussing the specifics of the GEARS experiment. What unique insights can we glean from the genetic makeup of bacteria in space? How will this knowledge shape the future of long-duration space missions?

With the advent of commercial LEO destinations, how is the space industry preparing for microbial challenges? What discussions are under way to make new stations more resistant to accumulating microbes?

Lastly, we tackle the ultimate Doomsday medical scenario: What would happen in case of a serious illness outbreak on the ISS or during a long-term flight to Mars? We'll discuss how scientists are trying to mitigate the potential dangers of bringing Earth germs to another planet and the risks of bringing something dangerous back to Earth.

Don't miss this episode of Talking Space as we navigate the intriguing world of health and sickness in space.
