Danish ISS astronaut trials Australian designed SkinSuit

14 October 2015

An innovative SkinSuit designed to reduce the debilitating physical effects of space flight has been trialled for the first time on the International Space Station.

The SkinSuit is the brainchild of Dr James Waldie, aerospace engineer and senior research associate at RMIT University in Melbourne, Australia. Denmark’s first astronaut, Andreas Mogensen, spent ten days in the ISS last month and pulled on the SkinSuit to test its effectiveness in the weightless conditions.

Inspired by a striking bodysuit worn by Australian gold medallist Cathy Freeman at the 2000 Sydney Olympics, Waldie and his collaborators have spent more than 15 years getting the suit into space.

“Seeing live video of Andreas wearing SkinSuit on board the ISS was thrilling - I felt an enormous sense of achievement that my concept was finally in orbit,” says Waldie.

Skin-tight and made of bi-directional elastics, SkinSuit has been designed to mimic the impact of gravity on the body to reduce the debilitating physical effects space flights have on astronauts’ bodies.

In the weightless conditions in space, astronauts can lose up to 2 percent bone mass per month.  Their spines can also stretch by up to 7cm, with most suffering mild to debilitating pain.  Following flight, astronauts have four times the risk of herniated discs as the general population.

“Given the impact of atrophy on astronauts in space, I wondered if a suit like the one worn by Freeman could fool the body into thinking it was on the ground rather than in space, and therefore stay healthy,” says Waldie.

The special design of the suit means it can impose a gradual increase in vertical load from the wearer’s shoulders to their feet, simulating the loading regime normally imposed by bodyweight standing on earth.

For the ISS flight, the European Space Agency wanted to explore if the suit could counteract the effects of spaceflight on the spine. 

“We believe if we can reduce spinal elongation in space, we can reduce the stress on the intervertebral discs.  This should help with pain in-flight, and the chances of slipped discs post-flight.”

SkinSuit has been developed in collaboration with scientists from the Massachusetts Institute of Technology, Kings College London and the European Space Agency.  It was manufactured by Italian firm Dainese, best known for producing motorbike leathers for racing.

Mogensen has since returned to Earth but is yet to publicly report his findings as he undergoes extensive de-briefing.
