Astronaut Blood May Not Act Weird in Space After All – Space.com

Read article - Quotes Jay Buckey, professor of medicine and adjunct professor of engineering, about a new study that shows that astronauts might not be anemic at all while in space — instead, it's a condition that develops when they land. The finding could mean more time safely spent in space, such as a mission to Mars or colonizing the moon would require. "The thing is, they're going to have a little adaptation to go through to go from being weightless to being back in a gravity field again," says Buckey, who was not involved in the study.
