Astronaut tests non-smelly space pants

A Japanese astronaut on the International Space Station is testing a pair of special non smell underwear.

Koichi Wakata, 48, will wear the special antibacterial polymer pants for seven days on the STS-119 mission to test their effectiveness.

The underwear has been developed by Japanese researchers in a bid to create clothing that reduces smells, absorbs sweat and provides insulation.

Most astronauts change their clothes after three days and NASA are said frown on those who opt to turn them inside out.

Why the pants are being tested in space is not clear ... but at least it means we won't be stood next to someone on the tube who has been wearing the same undies for seven days.
