Microgravity effects refer to the changes that occur in the human body and other materials when exposed to a low-gravity environment, such as that found in space. In microgravity, the force of gravity is significantly reduced, leading to various physiological changes, including muscle atrophy, bone density loss, and fluid redistribution. These changes can impact astronauts' health during long-duration missions aboard the International Space Station. Additionally, microgravity affects physical processes, such as combustion and fluid dynamics. For example, flames behave differently in space, forming spherical shapes instead of the typical teardrop shape seen on Earth. Understanding these effects is crucial for ensuring the safety and well-being of astronauts and for advancing space exploration technologies.
