Astronaut Fashion: Spacesuits Through the Years
Imagining what the iconic picture of Buzz Aldrin on the moon might look like if he weren’t wearing a space suit can be stomach churning when you think about all of the elements that the personal space ship protects against. Without the pressurised gas to maintain internal pressure, all of the gases in his body would expand at a rapid rate, causing his blood to boil, and he would have no oxygen to breathe. NASA has a great interactive that shows a friendlier cartoon version where Andy the Astronaut demonstrates what would happen to a human in space without protection, then you can take a virtual tour of the space suits that have made history. Enjoy watching the evolution of the space suit as you scroll through this collection.

If Martian life exists, its higher forms might look somewhat like these, [Carl Sagan] conjectures. Shielded from ultraviolet radiation by a glassy shell, an animal gorges on mossy ground cover among plants with cabbagelike tops. Outer leaves close at night to protect buds from cold. Like the ground cover, these plants have developed an ultraviolet tolerance. Others, lacking such immunity, wear transparent bubbles.
Man, I can’t wait for Curiosity to come across these guys!](http://24.media.tumblr.com/tumblr_m82cdjjxvR1rp3sedo1_500.jpg)
