Quick Summary

Microgravity refers to a condition of near-weightlessness experienced in space, where accelerations are minuscule, about one-millionth of Earth's gravity. This environment is crucial for materials science research, allowing scientists to study how substances like metals, alloys, and polymers behave without the influence of gravity.1234

This unique setting enables the creation of materials, such as highly ordered protein crystals and tissue-like structures, that are difficult or impossible to produce on Earth. Research also extends to fluid physics, combustion science, and fundamental physics, offering insights that can benefit manufacturing processes and improve human health on Earth.34

Microgravity research
A spacecraft orbiting Earth is essentially in a continuous state of free fall. All objects associated with the spacecraft, including any crew and other contents, are accelerating—i.e., falling freely—at the same rate in Earth’s gravitational field (see Earth: Basic planetary data). As a…
