Abstract :
The NASA/DOE LuSEE Night experiment [Bale et al. (2023), arXiv:2301.10345] will be deployed on the lunar farside in late 2026 to make full-Stokes spectral measurements of the radio sky below 50 MHz using a simple crossed-dipole antenna system. LuSEE Night will be a pathfinder for future farside observatories, demonstrating many of the (quite ambitious) technologies required to make synoptic, radio quiet measurements throughout the lunar night.
Additionally, a second experiment LuSEE Lite will make direct measurements of the DC electric field on the lunar surface which is thought to be a controlling factor for the electrostatic dust levitation which gave rise to the lunar ’horizon glow’ observed by the Apollo astronauts.
A ’stretch’ goal of LuSEE Night is the first measurement of the 21cm spectral features associated with very high redshift (z 100) universe. The foregrounds to this signal will be dominant by several orders of magnitude but offer their own novel scientific opportunities.
I will describe some of the unique measurements of solar system radio sources available to LuSEE Night from the lunar farside, including observations of the active Sun, the quiet solar corona, the outer planets, and potentially in situ signatures of the lunar ionosphere. I will also describe LuSEE Lite measurements, which will complement those of LuSEE Night and will include a 20 MHz Nyquist radio measurement from near the lunar South pole
