Space Wants to Kill Us

Posted by on November 8th, 2009

In Michael Crichton’s 1969 novel Andromeda Strain (and subsequent film and recent TV mini-series) the premise is about an extra-terrestrial microorganism that threatens to wipe humanity off the planet through truly horrific blood clotting. It was an interesting take on the threat from outer space scenario.

So if we earthbound humans have to worry about space organisms turning our blood into dust, what do astronauts on long term space missions have to stress out about? According to a report in the Journal of Leukocyte Biology (via PopSci): Earthborn bacteria mutating into killer diseases.

It turns out that bacteria that we’ve evolved pretty good defenses for could overwhelm our immune systems if we’re cooped up together on long term space voyages. So add that to the already growing list of space hazards including radiation, zero-g bone loss, space madness and your holodeck trying to kill you.
