Astronauts may soon be sporting smart glasses to help with their work on the International Space Station, according to the U.S. space agency.

The agency recently entered into a contract with the Osterhout Design Group to provide smart glasses for training purposes, and eventually for use in space. The smart glasses would have the ability to display a large array of information as one 3D image, as well as monitoring and recording the astronaut’s position, actions, and even attitude while performing routine tasks such as spacewalks. ISS officials hope that the glasses may help enable longer, more in-depth missions in the future.

“As electronic directions and instructions replace paper checklists and longer duration missions are considered, there is a need for tools that can meet evolving demands,” said NASA’s engineering director Lauri Hansen. “ODG’s technology provides an opportunity to increase space mission efficiencies and we are pleased to explore its potential in human spaceflight while also advancing its use here on Earth.”

The glasses will allow astronauts to measure the progress they are making while performing repairs by overlaying a 3D schematic onto reality. The devices would also act as an electronic checklist, as well as issuing important reminders about handling certain pieces of equipment. A camera embedded in the glasses would allow astronauts to take pictures they could immediately transmit to ground control or share with other members of the space station.

According to a statement by the ODG managing team on their website, the “sixth-generation Smart Glasses are the first to be made available to a broader customer set.” They also claim the products are “untethered for the ultimate hands-free experience.” Boasting “military-grade technology,” the glasses run on the Android Jelly Bean operating system.

The glasses took six years and $60 million to perfect. NASA had originally considered putting its own engineers onto developing the project, but eventually decided to rely on an independent commercial contractor. NASA hopes that the new technology will make routine tasks and repairs safer and more practical for astronauts.
