Lunar Super Low-Frequency Atomic Seismometer

The Lunar Super Low-Frequency Atomic Seismometer is a completed NASA DALI technology project for lunar landers and seismic networks. It uses atom interferometry with laser-cooled atomic test masses as the inertial reference to target unusually stable seismic measurements from hertz frequencies down to microhertz, enabling long-period lunar seismic waves, normal modes, and tidal measurements beyond Apollo-era instrument capability.
