Space is a cold-blooded killer.

It’s the largest thing in existence, and it wants you dead. We technically live in it, and it wants you dead. The ways one could meet an untimely demise in the vastness of space can be assorted and ultimately macabre. If you’re living the dream in orbit, without a spacesuit, you’ve only got a couple of minutes to beam that selfie back to Earth.

Always wear your spacesuit, your personal spacecraft.

Tell a friend. Save a life.

And don't forget to visit the interactive Astronaut Database, the most complete record of spacesuit wearers.
