digquickly say: Yes, ..., by the fact that we are growing plants in space means that bacterium are in space.

We also accidentally sent microbes to the moon in 1967 (after a technision had sneezed on a Surveor3 TV Camera), and then harvested them 2 years later when we brought the camera back on Apollo 12. The microbes revived after living in and airless vacuum, intense radiation from the sun, extreme heating and cooling conditions. This actuall created a new study in science known as "Extremophiles".

BTW, I should note that any time we send a Human or Animal into space we send bacteria into space. However, even inanimate objects like satellites, probes, and etc. receive earth based bacteria despite our best clean room efforts during assembly. It's just a given that once you are in Earth's bisos-phere, microbes are going to find you. You just can't get rid of them.

tham153 say: Any launch with living creatures, whether USSR's dogs, humans, etc, will necessarily have bacteria aboard, since dogs, humans, etc are not sterile

Brigalow Bloke say: A large proportion of any astronaut's body is bacteria. Some biological experiments have been does on the ISS.
Google ISS experiments.

quantumclaustrophobe say: Not on purpose... When Apollo 12 landed on the moon, it was 600 yards away from the unmanned Surveyor III probe that had been on the moon for 18 months. They returned some of it's parts - and discovered some still living bacteria on those parts.

James say: Yep. Some folks call us Bacteria. I prefer to think of us as a nasty disease. Seriously, when we sent astronauts into space, their bacteria went along for the ride.
