I didn't realize that being an astronaut was such a dirty job since it seems fairly sterile but since they have to exercise at least 2 hours per day they get sweaty which isn't a problem here on Earth,but there are no laundry facilities in space so they literally wear there clothes,socks and underwear included,until they can't stand them. NASA has finally teamed with Procter & Gamble to come up with a solution, at the current time they are sending 150 lbs of clothes per person per year which are disposed of when they can no longer be worn. Since water is at a premium in space it would have to be reused but I was wondering whatever happened to the silicone beads that were supposed to be the next laundry breakthrough? It seems like they would be the perfect fit for this dirty job.
