NASA’s Cold Atom Lab (CAL) is a groundbreaking research setup that introduces a new frontier of quantum science to the International Space Station (ISS). At the heart of this lab’s innovative observations is an atom interferometer, a quantum measurement tool capable of detecting gravity, magnetic fields, and other forces. Using this device, scientists have achieved a series of first-of-its-kind observations.
“It took dedication and a sense of adventure by the team to make this happen,” said Jason Williams, the Cold Atom Lab project scientist at NASA’s Jet Propulsion Laboratory in Southern California. “Reaching this milestone was incredibly challenging, and our success was never guaranteed.”
Bringing Quantum Technology to Space
The atom interferometer, developed in 1991 and based on earlier research dating back to the 1930s, has previously been used in experiments testing general relativity at extremely small scales. A 2009 measurement of gravitational redshift and a 2020 test of the principle of equivalence reinforced our current understanding of relativity. Sending the device into orbit is a novel application scientists have long been eager to explore. The microgravity environment of space enhances measurement time and sensitivity, offering new opportunities for discovery…
