NASA wants space washing machine for ISS ........ NASA have moved at last to tackle the problem of dirty astronauts by commissioning a microwave with air-jets to clean underwear in space. There are no washing machines on the International Space Station so grime-encrusted nauts will wear underwear for 3-4 days and other items of clothing for months, before disposing of the dirty laundry by hurling it into the atmosphere to burn up in old Progress cargo capsules, attempting to wash it in a plastic bag or even - yuck - using it to grow plants in...... NASA have selected small disinfectant business UMPQUA to make a prototype of a low-water, low-power washing machine that could enable the laundry to be done 250 miles above the earth's surface - or much further afield, on deep space craft or in bases on the Moon or Mars.
