New Study Confirms Solid Core of Moon, Raises Questions on Disappearance of Magnetic Field
Utilizing Monte Carlo algorithmic modelling technique, drawing from Apollo seismic and GRAIL gravity field data, researchers at CNRS, Paris Observatory and other French institutions conclude Moon contains solid inner core ~516 km diameter with ~7,822 kg / m3, likely composed of Fe, representing ~15% relative to total size (by comparison, Earth’s inner core is ~20%); Findings concur with 2011 NASA study, and suggest mantle overturn activity as mechanism; Authors stress ramifications for ‘evolution of the Moon magnetic field’; Farside Seismic Suite to further investigate structure of Moon on Draper CLPS CP-12 mission lander NET 2025
Selected from 62,719 submissions across South Korea by a 1000-person focus group, Korea Pathfinder Lunar Orbiter, now Danuri (Moon Enjoy), set for launch on 2 Aug (19:37 EDT) to 100-km Moon orbit on SpaceX Falcon 9 via ballistic lunar transfer; 678-kg spacecraft is outfitted with 6 instruments – KARI-built Lunar Terrain Imager, Wide-Angle Polarimetric Camera, Magnetometer, Gamma-Ray Spectrometer, Disruption Tolerant Network Experiment Payload and NASA provided ShadowCam; NASA will also assist Danuri with ground station / comms / navigation support and 9-member KPLO Participating Scientist Program
First space debris to strike Moon, likely upper stage of LM-3C used to deliver Chang’e-5 T1 to lunar free return trajectory, will “use its cameras to attempt to identify the impact site”; LRO 20x165km eccentric polar selenocentric orbit is calibrated to reach perilune over the Moon South Pole (now pinpointed to “halfway between 10 and 11 o’clock” of an imaginary clock superimposed over Shackleton Crater), requiring “weeks to months” to achieve favorable conditions; Impact may be visible in Release 50C (15 June) or 51A (15 July) 
As prospects of sustained operations on the Moon nears, unique orbital mechanics of Earth-Moon system draw attention of mission planners and
