Which new exercise methods can be developed under microgravitation conditions for astronauts in space? This is a recently carried out study that was submitted to the Wearables Workshop and the University Challenge of the 2025 Technology Collaboration Center (TCC) when a team from Rice University Engineering student who developed a new type of space training cable tree that could make training under microgravity easier and comfortably.
For the study, the students designed and developed an adaptable astronaut training cable tree, which measures the load distribution to pressure points (shoulders, hips, etc.) to alleviate injuries caused by body shifts during training and temperature and humidity changes during training. Together with an improved technology compared to current belts, the new wiring harness also offers an improved level of comfort that prevents unnecessary skin trees.
“This challenge gave us the freedom to be innovative and to explore opportunities that go beyond the current cable harvest technology,” said Emily Yao, a rice bachelor and part of the team of five, which from four students and a doctoral student who developed the cable harness. “I am particularly proud of how our team worked together to build a functioning prototype that not only has real effects, but also offers a basis on which NASA and space companies can build and repeat. This makes the entire experience incredibly worthwhile. They are moments like this that remind me of why I love to design with and for people.”

In the end, the wiring harness was selected as the winner of the Best Challenge Response Award, which enables the way for this wiring harness to improve the function and use and possibly use real use by astronauts in space. In addition to improving movement and physical health, this wiring harness could be a thrust for the mental health of astronauts due to its simplicity and customizable design.
Astronauts who train in space have been taking place since the beginning of space age, since Gemini astronauts did not use exercise equipment to combat the effects of microgravity. From Apollo 7, NASA started with the exer-genius trainer, since Apollo 7 was the first mission to be enough space in the spaceship for astronauts to carry out exercises.
The exer genius consisted of a metal wave and nylons rope that the astronauts could adjust to their preferences. To use the exer genius, astronauts would put on the rope, which led to friction and resistance so that they can carry out more than 100 basic exercises in order to maintain muscle mass when combating microgravity. The exer genius was equipped with all crewed Apollo missions (Apollo 7 to 17), but was actually used by the astronauts on Apollo 7, 8, 9, 11. 12. And 16.
This study comes when NASA plans to send astronauts back to the moon for the first time since Apollo 17 in 1972 to create a permanent human settlement on the surface of the lunar. One of the goals of a moon settlement will be to test technologies for a future mission to Mars as part of the NASA moon architecture for a future occupation mission. After the successful mission of Artemis I in November 2022, the Mission Crewed Artemis II is planned for early 2026 and will send four astronauts around the moon to reflect the historical flight of Apollo 8. This is followed by Artemis III, which appears in mid-2027 with a four-person crew and landed on the surface of the moon.
Sending astronauts to the moon and Mars shows how people can endure longer periods with reduced gravity on both the moon and on the Mars with a sixth or a third of the earth. Although this is not the full microgravity, as experienced on the International Space Station (ISS), a reduced gravity still leads to a reduced muscle mass and bone loss, the astronauts have to maintain to continue their mission, especially if they touch the earth's gravity.
How will this new exercise belt help the astronauts in space in the coming years and decades? Only time will say it, and that's why we know!
As always, they continue and continue looking!
