From the famous Mercury Seven astronauts to the spacemen and women on the ISS, what these pioneers wear is absolutely critical when it comes to coping with life at Zero-G.

Much of the technology that Nasa develops for space flight eventually makes it into the products that we all use here on Earth, but what about wearables in space? We’ve pulled together some of the space-aged kit that astronauts wear in space and a few things they might wear in future…

Space watch

While the first watch to make it into space was a Sturmanskie, worn by cosmonaut Yuri Gagarin, the official watch of the Apollo moon landings was the Omega Speedmaster. But it was the Timex Datalink that was arguably the first smartwatch in space as it was also the very first watch capable of downloading information from a computer.

Made in conjunction with Microsoft, the watch has been approved by Nasa for space travel and has been worn by many astronauts since, but the Speedmaster remains the only watch certified for spacewalks.

Health monitoring

Wearable health monitors have been a big part of human spaceflight from the start, with all of the Mercury, Gemini and Apollo astronauts wearing biosensors ranging from a belt-like harness to a full biosuit comprising heart rate, body temperature and blood pressure monitors.

Nasa recently tested out Google Glass and Bluetooth heart rate monitors during simulated space walks on its Neemo (Nasa Extreme Environment Mission Operations) underwater facility for potential use on the ISS in future.

GoPro

Action cam specialist GoPro was named ‘official on-board camera of Nasa’ in 2011. Used by astronauts on the International Space Station (ISS), and famously by Felix Baumgartner in his epic space jump, the brand’s Hero 3 is compatible with a huge selection of mounts, ideal for keeping the action steady in zero gravity.
