Understanding space suit technology1 min read

When Neil Armstrong set foot on the Moon’s surface in 1969, he was wearing a space suit developed by the US company ILC Dover, which is based in Delaware.

Space suit technology has continued to evolve over the decades since, with ILC Dover at the forefront.

The suit below is designed for use by astronauts at the International Space Station.

It weighs 280lb (127kg), and on Earth astronauts struggle to support the weight of the suit on their own.

 

But because of the weightlessness experienced in orbit, it can be comfortably used for space walks.

It performs a number of functions.

One is to protect astronauts from extreme temperatures. In Earth’s orbit, a surface in the shade can get as low as -129C (-200F) and, in sunlight, as high as 121C (250F).

Space suits provide a supply of oxygen, but they also replace the pressure experienced at low altitude.

Above 63,000ft (19km), exposed human tissue swells and bodily fluids like mouth saliva and water in the eyes start to boil.

Suits like the one above are pressurised to 4.3 pounds per square inch (30 kilopascals).

Bill Ayrey, a tester for ILC Dover, says the company is now working on advanced suit designs for Nasa, using new materials.

He said that should Nasa ever try to send astronauts to Mars, the suit requirements would be completely different from anything they had designed previously.
