The last frontier: washing clothes in space

Must Read

The space agency is planning to conduct a series of experiments using specially designed detergents from Procter and Gamble (PG.N) to find a long-term solution to the problem, the U.S. consumer goods giant said on Tuesday. The vital nature of water on space missions has meant that astronauts have simply jettisoned used clothes, happy in the knowledge they will disintegrate as they re-enter the atmosphere.

As a result, NASA sends 160 pounds of clothing per crew member to the International Space Station per year. Identical experiments will be conducted on Earth at the same time, using the same materials in order to study the differences, P&G said.

P&G will also send some additional equipment for treatment and image analysis, even though the ISS has most of the equipment necessary for the experiments. Reporting by Siddharth Cavale; Editing by Patrick Graham and Saumyadeb Chakrabarty

Labeled NASA Tide after P&G’s main washing powder, the first tests on the new detergent to evaluate the effects of micro-gravity and radiation will take place on a cargo flight to the ISS next year and, subsequently, in the space station itself. For the longer run, with the U.S. agency and Elon Musk’s Space X eyeing manned missions to Mars, there needs to be a more sustainable solution.
