Apollo Astronauts' Health Issues Reveal A Hurdle To Deep-Space Travel
When astronauts left the protection of Earth's magnetic field, it apparently increased their risk of cardiovascular problems.By Evan Thomas | July 28, 2016
Even with 55 years of practice, there's a risk to deep space travel we still don't know how to counter: radiation.
A new study shows Apollo astronauts — who were subjected to the radiation of deep space — die of cardiovascular diseases four or five times more often then the rest of the astronaut corps.
The study is the first to examine mortality among those who were on the Apollo missions, which isn't the largest sample size to work with, but it found 43 percent of Apollo astronauts who've died, died of cardiovascular problems.
