Astronauts typically need a couple of days to get used to microgravity. But as Tim Peake demonstrates in this new video, astronauts eventually develop an extreme tolerance to all that spinning and floating.
We all dream of journeying (or living) among the stars. But space is a spectacularly awful place for humans, and we’re not suited for life there at all. And yet, it doesn’t have to be that way. Here are all the ways we’ll need to re-engineer the human body, in order to make space our home.
This image of blood vessel cells stained for identification is a stunning reminder: We are made of star stuff.
As if astronauts didn't already have enough health-related concerns to be worried about, a new study shows that microgravity environments speed up biological aging and the onset of cardiovascular disease by affecting blood vessel cells.
Back in November 2011, a multinational crew of six ended their 17-month long simulation to Mars and back. Confined to a trailer for 520 days, the pretend-astronauts had every detail of their lifestyle tracked, including their sleep-wake cycles, physical movements, intellectual activities, and light exposure. Now,…
While we have a pretty good idea what the first humans will eat on Mars, we're a little less certain about what their meals will look like on the way there. Alas, because there are no drive-throughs between Earth and the red planet, food scientists are having to come up with innovative, healthy, and tasty food…
