Description
We've spent over sixty years learning what space does to the human body, and the list is long: bone loss, muscle wasting, vision changes, radiation exposure, immune system disruption, and the psychological toll of isolation. Every one of these is a problem we have to solve before we can send crews on multi-year missions.
The Small Steps & Giant Leaps community is gathering to look at the full arc—where this research started, what decades of orbital medicine have taught us, and what still stands between us and a healthy human presence across the solar system.
Expect conversations on:
The history of space medicine—from the first flights to decades aboard the ISS
What microgravity does to the body—bone, muscle, the cardiovascular system, and more
Radiation and the exposure crews face beyond Earth's protective field
Countermeasures—exercise, pharmaceuticals, artificial gravity, and what actually works
The Mars-mission problem—years in deep space with no resupply and no quick return
Where we go from here to make long-duration human spaceflight survivable and routine
You can't settle the solar system with a crew that can't stand up when they land. Come understand the science of keeping humans alive out there.
