Preventing Sick Spaceships

An anonymous reader writes "The official NASA home page has a writeup on one of the lesser-known dangers of living on a Space Station: space germs. 'Picture this: You're one of several astronauts homeward bound after a three-year mission to Mars. Halfway back from the Red Planet, your spacecraft starts suffering intermittent electrical outages. So you remove a little-used service panel to check some wiring. To your unbelieving eyes, floating in midair in the microgravity near the wiring is a shivering, shimmering globule of dirty water larger than a grapefruit. And on the wiring connectors are unmistakable flecks of mold.' The article goes on to describe the unlikely circumstances that form these micro-ecologies, and what astronauts do to deal with the situation."

Bottom Line

Eight year round trips to Mars are never going to work. Name me one voyage that lasted longer than even one year without having to dock in some fashion.

We will never be able to fully explore, experiment and gather resources in out solar system if trips between planets take 5+ years. We need to look into saner proplusion systems that seperate the ground to orbit engine from the interplanetary engine. Even sci-fi shows seem to have grasped that fact.

Perhaps microbe contamination is a good thing

Before anyone mods me down for trolling consider this: do you really think it would be a good idea for astronauts to exist in a completely sterile enviroment for years on end? What do you think this would do for their immune systems? At the very least they'd be seriously impaired by the time they came back to earth and possibly they could even die of some common microbe that is of no concern to people with healthy immune systems. At the worst their immune system could go into auto immune disease mode and then you could well end up with your spacecraft arriving at mars with just corpses strapped in the seats.
