Let's Talk Space Medicine – Details, episodes & analysis

During this orbit we look ahead to AsMA 2023 in New Orleans with special guest Daniel Kaganov!

During Orbit 12 I chat with Dr. Michael Pohlen, MD about Space Radiology!

During this orbit we gained a new space-nerd-friend Vienna (@Vistronaut), an Australian medical student, to help us answer the question of whether muscle or bone presents a more pressing challenge for human spaceflight! Astronauts lose significant muscle bulk and bone mass during stays in microgravity but which is more important in terms of astronaut health and can a new device to help us jump in space be a novel solution (@Perform_Science)?

During this orbit I worked with my space-nerd-friend Ryan on how we can make space for everyone! Disability presents unique questions to the spaceflight community especially with routine civilian-spaceflight on the horizon. So what are some medical considerations for these "parastronauts" and could an earthly disability actually be of benefit during space travel?

During this episode I explored the question: when attempting to mitigate radiation concerns for astronauts on long duration space missions, what will be better, engineering solutions or precision medicine?

During this episode, I was joined by my space-nerd friends Ryan and Vlad to discuss everything under the sun about the stuff that comes from the sun, radiation! Radiation presents perhaps the most significant risk to astronauts trying to live in space as well on the Moon and Mars. So what types of radiation will be encountered, what are some of the medical consequences, and what role could precision medicine play?

During this episode I explored the question: what are the likely causes of space motion sickness, and could a surgical intervention be necessary for future Martian colonists?

Astronauts experience significant challenges when returning from an extended stay in space. What does this mean for when humans land on Mars, and what are the medical hurdles to overcome to take that first step?

Instead of an episode it's an orbit! The name for our longer form podcast cast content. Here we discuss what we hope to accomplish!

During this episode I was joined by my space nerd friend Ryan to try and explore the question, what are the medical consequences of chronic high levels of CO2 when aboard the ISS and does simply having medical grade oxygen on hand fix this?
