Resilient quantum sensor monitors Earth's magnetic field from space for 10 months

Phys · · 562 words · By Sam Jarman

Researchers from Hasselt University developed a diamond-based quantum sensor called OSCAR-QUBE to measure Earth's magnetic field. The device was tested on the International Space Station for 10 months, demonstrating potential for higher resolution geomagnetic mapping in future small satellite constellations.
