Keeping clean in space is not straightforward.
But thanks to the efforts of 24-year-old Angelo Grubisic, from Walsall, astronauts on future manned space missions could be taking an in-flight shower.
Mr Grubisic recently completed a zero gravity flight to test a revolutionary shower system - supported by sponsorship from Jonathan Lee Recruitment in Stourbridge.
Having a shower in space is not only hazardous because free-floating water can short electronics equipment, but astronauts also run the risk drowning if they inhale water in zero gravity.
Mr Grubisic, who is a Master of Space Studies and the only British student at the International Space University, fought off international competition to gain a place on the zero gravity test programme on board the European Space Agency's Student Parabolic Flight Campaign.
In parabolic flight, a aeroplane goes temporarily into freefall providing the students with up to 22 seconds of zerogravity.
The shower uses water repellant surfaces to stop water settling on the walls. Then, when the astronaut is finished, a heated cyclone air system quickly dries the inside before the astronaut leaves the cabin.
