Abstract: A new era of exploration of the low radio frequency Universe from the Moon will soon be underway with landed payload missions facilitated by NASA’s Commercial Lunar Payload Services (CLPS) program. CLPS landers are scheduled to deliver two radio science experiments, ROLSES to the nearside and LuSEE to the farside, beginning later this year. These instruments will be pathfinders for a 21-cm Global Signal Cosmology telescope (DAPPER) and a 10-km diameter interferometric array, FARSIDE, composed of 128 pairs of dipole antennas. ROLSES and LuSEE, operating at frequencies from ~100 kHz to a few tens of MHz, will investigate the plasma environment above the lunar surface and measure the fidelity of radio spectra on the surface. ROLSES will measure the photoelectron sheath density to better understand the charging of the lunar surface. LuSEE will measure the local magnetic field and exo-ionospheric density, interplanetary radio bursts, and the galactic synchrotron spectrum. DAPPER is designed to open a new window to the cosmos, the Dark Ages and Cosmic Dawn, using the highly redshifted hyperfine line of neutral hydrogen observed from 10-110 MHz. FARSIDE will break new ground by imaging radio emission from Coronal Mass Ejections (CME) beyond two solar radii, and detect auroral radio emission from the magnetic fields of nearby potentially habitable exoplanets.
