Lead story
Despite its awe-inspiring beauty, space is an incredibly hostile environment. Humans who leave Earth must work to manage a myriad of threats to their health, from muscle and bone deterioration to cosmic radiation exposure. Spending a long time in an environment without gravity can even cause your brain to sit higher in your skull.
Rachael Seidler is a kinesiologist from the University of Florida who’s spent years working with astronauts to study the health effects of going to space. She’s part of a NASA team that’s trying to understand what health challenges the agency needs to overcome before humans take the long journey to Mars. Seidler outlines some of the key hazards her colleagues are hoping to mitigate and some of the innovations that might make space a little more habitable.
If you find this work as fascinating as I do, I hope you will support the work we do by donating to our brief back-to-school fundraising drive. Thank you!
