Space base: 20 years of life on the ISS

Two decades ago, on November 1, 2000, three humans left Earth for a new life in space. Since Then the International Space Station has been home to a rotating international crew of six astronauts. Metro finds out how they’ve survived

The ISS is the biggest human-made structure in space, measuring 358ft in length, which is about as long as a football pitch. A collaboration between Nasa, Russia’s Roscosmos, Japan’s Jaxa, the Canadian Space Agency (CSA) and the European Space Agency (ESA), the ISS essentially acts as a unique orbiting laboratory where astronauts test out new technologies and carry out scientific experiments in microgravity.

Around 250 to 300 scientific investigations are carried out at any given time and help prepare for future space missions — as well as helping us. For example, the first UK-led experiment on the ISS recently studied a horde of worms to test the effect of muscle loss in space. That could also help us to understand muscle loss in old age….

How VR and AR could turn you into a bona fide space explorer

12444-c9a15545b69790cfe97a93810d1c1e12Mainstream virtual reality is still in its infancy but it’s been tackling the final frontier – space – for years. Now the latest hardware, such as the Oculus Rift, HTC Vive and Samsung Gear VR headsets, combined with sophisticated 360-degree filming techniques, is finally bringing space exploration to the masses.

VR’s ability to produce large-scale 3D environments not only offers armchair astronauts a glimpse of what life is like in space, it is now also more helpful than ever at aiding real-life astronauts in their jobs both on Earth and out there. 

What’s more, augmented reality can offer spacemen and women a new perspective by merging the worlds of Earth and space. Compared to VR, though, augmented reality still has some way to go before we start to see smartglasses and AR helmets both on our faces and in our homes.

Training astronauts

While virtual reality has been relatively slow to catch on in the mainstream, NASA has been using it for more than 25 years because it’s simply one of the best ways to replicate space while remaining safely on home soil.

“Simulated environments have always been important in astronaut training,” explains Jason Crusan, director of NASA’s Advanced Exploration Systems Division.

The Mercury, Gemini and Apollo astronaut crews all spent at least one third of their training time in simulators and contemporary crews use VR simulations to train for tasks on the International Space Station (ISS).

Early NASA headsets were improvised affairs – the first prototype of the Virtual Environment Workstation headset was built from a motorcycle helmet – and the American space agency has continued to update the tech involved. Astronauts now use NASA’s Virtual Reality Lab (VRL), located at the Johnson Space Center, to train for missions aboard the ISS. Using a headset, real-time graphics and motion simulators, astronauts train to carry out tasks during microgravity spacewalks.

A vital part of the training involves using their powered jetpack – the Simplified Aid For EVA Rescue (SAFER) – which carries very limited fuel, to navigate their way back to the ISS should they get stranded in space. 

The ability to recreate a life-size 3D environment makes VR ideal for astronaut training and now NASA is looking at using augmented reality to keep reality in the frame.
