To boldly go where no one has gone before has certain risks, even 'just' staying 240km up there. Should I cancel my reservation for a trip to Mars?
"An Alarming Discovery in an Astronaut’s Bloodstream
A study has turned up a side effect of human spaceflight that no one had observed before.
Astronauts are more than cosmic travelers. They’re also research subjects in the careful study of what exactly outer space does to the human body. On the ground, researchers measure vitals, draw blood, swab cheeks, and more. In orbit around the Earth, the astronauts do the work themselves.
That’s how they found the blood clot.
An astronaut was carrying out an ultrasound on their own body as part of a new study, guided in real time by a specialist on the ground. A similar test before the astronaut launched to space had come back normal. But now the scan showed a clump of blood.
“We were not expecting this,” says Karina Marshall-Goebel, a senior scientist at NASA and the author of the study, published earlier this month. “This has never been reported before.”"
