Need to Test a Space Suit? Head to Iceland – WIRED

How do you prepare for a mission to the moon or Mars? You cant take a quick jaunt to get the lay of the land, so you need to find the next best thing. And there isnt much better than our very own slice of an alien world right here on Earth: Iceland.

Famously used by the Apollo astronauts in the 1960s to prepare for their historic lunar excursions, Icelands unique features and terrain make it an ideal testbed for missions to other worlds. You have subsurface ice. You have lava tubes. You have areas of intense volcanic activity, says Daniel Leeb, executive mission director of the Iceland Space Agency (ISA), a private research organization not affiliated with the Icelandic government. Iceland has the most diverse set of terrestrial analogs in close proximity to one another that exist anywhere on Earth.

In 2019, researchers with the ISA made use of these traits to perform a dry run for a mission to Mars. Participants donned a spacesuit called Mars Suit 1 (MS1), made by the Rhode Island School of Design (RISD), and performed activities that future astronauts might one day have to contend with on the Red Planet. The suit provided that otherworldly experience, with feet very much on terra firma.

Now researchers have returned to Iceland with an upgraded version of the suit, dubbed the MS1.5, to be put through its paces too. This time the goal of the research, conducted by the ISA in partnership with the private company AdventureX, was to test some of the suits components with NASAs Artemis program in mind, which is hoped to send humans back to the lunar surface later this decade.

Activities included climbing in and out of lava tubes and collecting samples from the walls, such as bacteria, that might be a staple of lunar missions. The upgraded suit also tested new carbon dioxide sensors and a biometric undergarment that recorded data from the astronauts, including their heart rate and breathing rate. Some issues arose; the visor experienced condensation from the temperature swings, for example, which will likely be more extreme on the moon.
