Mixed Reality headsets aren’t only for playing VR games on Earth: The astronauts aboard the International Space Station are making use of an Augmented Reality (AR) system based on commercial Microsoft HoloLens hardware with custom-designed software. Recently, NASA astronaut Megan McArthur used a HoloLens headset to perform a hardware replacement on a highly complex piece of equipment: The station’s Cold Atom Lab.
The ISS’s Cold Atom Lab is a particle physics instrument that chills atoms down to almost absolute zero, or minus 459 degrees Fahrenheit (minus 273 degrees Celsius), at which temperature atoms move much more slowly than usual and can be studied in greater detail.
This technology is complex, and so maintaining the instrument or replacing parts requires careful instructions sent to the ISS crew from Earth. With the mixed reality headset, astronaut Megan McArthur could see an overlay of text and information when she looked at hardware like cables. And the team on Earth could even use an arrow in her vision to point to particular cables she needed to unplug.
“Cold Atom Lab is investing in the use of this technology on the space station not just because it’s intriguing, but because it could provide additional capabilities for these complex tasks that we rely on astronauts to perform,” said Kamal Oudrhiri, Cold Atom Lab’s project manager at NASA’s Jet Propulsion Laboratory, in a statement. “This activity was a perfect demonstration of how Cold Atom Lab and quantum science can take advantage of mixed reality technology.”
With the replacement hardware, the instrument now has a new capability: Producing ultracold potassium atoms. The Cold Atom Lab team on the ground says this means it can be used in a whole variety of new particle physics experiments.
“This repair activity allows potassium gases to also be studied in Cold Atom Lab, which will enable scientists to perform dozens of new experiments in quantum chemistry and fundamental physics using multi-species gases where the atoms interact with each other in interesting ways at the ultra-low temperatures only achievable in microgravity,” said Jason Williams, Cold Atom Lab’s project scientist.
“Our goal is for Cold Atom Lab to become an evolving science facility so we can quickly build on our research and work with the astronauts to add new hardware capabilities without the need to build and launch new facilities each step of the way.”
