Space Radiation Environment & Biological Effects

Beyond low Earth orbit, crews are exposed to galactic cosmic rays and solar particle events that are difficult to shield and raise long-term health concerns.

SMF-C-0009 · topic · draft

Space pharmacy & drug stability

What astronauts actually take, whether drugs still work in space, what happens to medications stored for months to years, and how to plan a formulary for missions far from resupply.

SMF-C-0001 · standard · draft

Medical standards overview

What NASA's crew health standard actually requires, how astronauts are medically selected and recertified, and what that means for a clinician who sees space travelers.

Postflight recovery & surveillance

A timeline of what to expect after landing — day 0 to day 45 and beyond — what NASA measures and when, which problems can persist for months or years, and how lifelong occupational surveillance works.

Clinician quick-start

A one-page orientation for GPs, emergency physicians, nurses and flight/aviation doctors: what to ask, what to check, the red flags, and where to find the details — before and after spaceflight.

Radiation limits & monitoring

NASA's radiation limits in plain clinical terms, how crew dose is monitored, what shielding can and cannot do, and what it means for a patient's lifetime cancer screening.

How evidence works

Why space medicine evidence is thin, what analogs and models can and can't tell us, how NASA rates risk, and how to read SMF's certainty grades.

Radiation & cancer

Space radiation may raise an astronaut's lifetime chance of cancer. There are no human data for this kind of radiation, so the risk is modeled, with wide uncertainty.

Risk & Gap Atlas

One plain-language page for each of NASA's 21 active human-system risks, grouped by hazard, with current ratings, knowledge gaps and research.

Behavioral health & cognition

Long missions can strain mental health and thinking. Problems in flight have so far stayed below diagnostic levels, but analog data suggest risk grows with mission length and isolation.

Medical conditions in flight

Illness and injury will happen on long missions. Far from Earth, the crew must handle them with limited supplies and no quick evacuation.

Cardiovascular adaptations

Weightlessness shifts fluids toward the head and deconditions the heart and vessels, causing light-headedness on landing. Whether space radiation adds long-term heart disease risk is unresolved.

Immune changes

The immune system becomes dysregulated in flight, which can reactivate dormant viruses and cause rashes. These changes persist through 6-month missions.
