Scientists Build Exercise Gear For Future Astronauts

Scientists are working on exercise equipment for future astronauts. On long space missions, the body does not work the same way as on Earth. Without gravity, muscles can weaken and bones can lose strength. That can make it harder for astronauts to function when they return. Researchers are now testing new gym tools designed for spacecraft. These devices must fit in limited space, be reliable, and keep astronauts safe while they train. Engineers also consider how the equipment will be used in microgravity, where normal movement feels different. The project is part of a wider effort to support long-duration travel. If the equipment works well, astronauts can keep exercising and protect their health during the mission.
