NASA’s Cold Atom Lab studies the quantum nature of atoms, the building blocks of our universe, in a place that is out of this world – the International Space Station. This animated explainer explores what quantum science is and why NASA wants to do it in space.

Quantum science has revolutionized our understanding of the physical world and led to new technologies including cellphones, computers, medical devices, and GPS. However, Earth’s gravity poses challenges for studying the quantum behaviors of atoms.

To overcome those challenges, Cold Atom Lab operates in microgravity. Using lasers and magnetic fields, scientists run the lab remotely from Earth, cooling groups of atoms to temperatures colder than any naturally occurring matter in the universe. Cold atoms, nearly motionless, reveal their behaviors more clearly. The absence of Earth’s gravity allows for prolonged atom study, opening new avenues in quantum exploration.
