The Competition to Equip Tomorrow’s Spacefarers

At an altitude of 8,500 meters (28,000 feet), Olympic bronze medalist Matthew Wells pulls with maximum effort on a rowing machine. As the aircraft executes a maneuver to simulate weightlessness, his body begins to lift off the seat for 22 seconds. Instead of water and a hull, he is suspended in the sky, participating in a unique trial for a British invention designed to keep future astronauts physically capable during long-duration missions.

This effort is part of a global competition to develop exercise technology suitable for upcoming lunar bases and space stations. While maintaining muscle mass and bone density is critical for astronauts, existing equipment often demands excessive daily time commitments to achieve adequate fitness levels.

“Isn’t it every kid’s dream to be an astronaut?” Wells remarked. “It’s an opportunity to be able to do something really different.”

Wells, who secured a bronze medal at the Beijing Olympics, described the prospect of contributing to space-bound technology as “out of this world.”

The development and testing of these innovations have involved major space agencies, including NASA, the Canadian Space Agency, the UK Space Agency, and the European Space Agency (ESA). ESA, for instance, facilitated parabolic flight tests, where aircraft climb and dive to generate brief periods of microgravity, allowing researchers 22 seconds to collect data before repeating the cycle for robust analysis.

The British device, known as HIFIm (High-Frequency Impulse for Microgravity), has already undergone testing for various exercises, including a “jumping” configuration. Dr. Meganne Christian, a Senior Exploration Manager at the UK Space Agency and a reserve ESA astronaut, explained that the concept originated from a competition among three European consortia tasked with designing exercise gear for the Gateway Space Station, an orbital platform intended for lunar operations.

Although NASA has effectively paused the Gateway project, Christian noted that the industry is at a “really exciting moment.” These devices remain relevant for new space stations and the lunar surface, particularly as Artemis missions aim to return humans to the moon with the intent of staying permanently.

The HIFIm is not the sole innovation in the pipeline. Globally, various teams are advancing their own projects. The Danish Aerospace Company (DAC), under commission from ESA, is developing the European Enhanced Exploration Exercise Device (E4D). Currently being tested by astronauts, the E4D features four modes: resistive training, cycling, rowing, and rope pulling. It also incorporates motion capture technology to allow users to monitor their performance metrics.

While these systems are optimized for extended missions, shorter trips also require specialized gear. The recent Artemis II lunar flyby utilized a specially engineered flywheel exercise device. NASA emphasizes that advancements in this technology, as well as the next generation of equipment, are crucial for preserving astronaut health.

The focus on exercise equipment serves as a reminder that despite operating in extreme environments, astronauts remain subject to human physiology. The human skeleton and muscles are highly adapted to handle gravitational forces present on Earth.

“In space we don’t experience any forces, our muscles, our bones immediately start to diminish because we’re not being loaded by those forces,” said Dr. Dan Cleather, a professor of strength and conditioning at St Mary’s University and a member of the HIFIm development team. Cleather designed the technology within the device that tracks exercise effectiveness.

Without regular physical activity, astronauts risk losing coordination and cardiovascular fitness, compromising their ability to perform essential functional tasks. However, exercising in the microgravity environment presents significant challenges, including issues related to weight...
