Space Adventure

Microbes inhabit the farthest reaches of the biosphere, floating up to six miles into the atmosphere. Microbes may inhabit space beyond our world. If life exists on other planets, it is most probably microbial life. If we humans are to ever colonize another planet or moon or go for long space flights, we must build life support systems using the help of microbes.

Frequent Flyers
The air around you is filled with microbes. Bacteria, fungi, algae, protists, lichens and viruses float in air currents. The numbers of microbes in the air range from 10 to 10,000 per cubic meter (cubic yard). They are found easily up to 3000 meters and as high as six miles into the air.

Microbes on Mars?
Is there life on Mars? Perhaps not now, though scientists are now looking to see if life existed on Mars in the past.

Missions with Microbes
Long term missions in space will require the cooperation of microbes. Microbes can be used to recycle water and nutrients aboard space craft and in extraterrestrial colonies.
