Lunar Degree-2 Tidal Love Number Determination Based on Combination of Four-way Radiometric Tracking and LLR Data

The Astronomical Journal
Lunar tidal Love numbers ( ${k}_{2}$ , ${h}_{2}$ , and ${l}_{2}$ ), critical for understanding lunar interior structures, are traditionally derived from methods such as lunar spacecraft radiometric tracking, Lunar Laser Ranging (LLR), and laser altimetry.

Evidence for Fine-grained Material at Lunar Red Spots: Insights from Thermal Infrared and Radar Data Sets

The Planetary Science Journal, 2023
Lunar red spots are small spectrally red features that have been proposed to be the result of non-mare volcanism. Studies have shown that a number of red spots are silicic, and are spectrally distinct from both highlands and mare compositions.

Space Weathering Properties of Chang’e-6 Soils and Implication for Regolith Evolution of Young Lunar Maria

The Astrophysical Journal Letters
Lunar soil samples from young maria (formed 3.0 Ga) and higher than the ∼21% found in the Chang’e-5 soils from younger mare (∼2.0 Ga). However, our spectroscopic study reveals that the Chang’e-6 soils are well developed, with high maturity, weak ...

The scientific case for renewed human activities on the Moon [PDF]

, 2004
It is over 30 years since the last human being stood on the lunar surface and this long hiatus in human exploration has been to the detriment of lunar and planetary science. The primary scientific importance of the Moon lies in the record it preserves of

Properties of Lunar Dust and Their Migration on the Moon

Space: Science & Technology
Lunar dust, the finest fraction of lunar regolith, has undergone important space weathering on the Moon. It not only serves as a record of the evolution of the lunar surface environment and the modification of mineral properties, but also influences the ...

Application of Machine Learning Techniques to Distinguish between Mare, Cryptomare, and Light Plains in Central Lunar South Pole−Aitken Basin

The Planetary Science Journal
We apply machine learning techniques to identify and map resurfacing units in the central South Pole−Aitken (SPA) basin using three Lunar Reconnaissance Orbiter (LRO) mission data sets: 321/415 nm and 566/689 nm band reflectance ratios from Hapke ...
