Nature, 1878 I was much interested in the account which your last number (vol. xviii. p. 197) contained of the presumably new lunar crater discovered by Dr. Klein in the Mare Vaporum. Is it really necessary to ascribe the formation of such a crater to present volcanic action?

The effect of craters on the lunar neutron flux [PDF]
Journal of Geophysical Research: Planets, 2015 AbstractThe variation of remotely sensed neutron count rates is measured as a function of cratercentric distance using data from the Lunar Prospector Neutron Spectrometer. The count rate, stacked over many craters, peaks over the crater center, has a minimum near the crater rim, and at larger distances, it increases to a mean value that is up to 1 ...

The Evolution of Autonomous Systems for Planetary Cave Exploration: A Review
Journal of Field Robotics, Volume 43, Issue 6, Page 4094-4115, September 2026.ABSTRACT The exploration of Subsurface Access Points (SAPs), such as lava tubes on the Moon and Mars, has gained significant interest due to their potential as stable environments shielded from surface radiation and temperature extremes. These sites are considered high‐value targets for detecting water and signs of ancient life, and assessing their ...

Corundum Discovered by SuperCam and the Perseverance Rover at Jezero Crater, Mars
Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.Abstract Mars is primarily composed of mafic mineral assemblages and their alteration products, but small, scattered rocks strewn across the landscape offer clues to greater petrological diversity. While traversing the Jezero crater rim, the Perseverance rover encountered several plagioclase‐rich light‐toned float rocks.

YOLO-SCNet: A Framework for Enhanced Detection of Small Lunar Craters
Remote SensingThe study of impact craters is crucial for understanding planetary evolution and geological processes, particularly small craters, which are key to reconstructing the lunar impact history. Detecting small craters, with diameters ranging from 0.2 to 2 km,

Identification of Multiscale Spatial Structure of Lunar Impact Crater: A Semivariogram Approach
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021 Identifying the spatial structure of lunar impact craters is necessary to increase our understanding of past geologic processes on the Moon. However, detecting multiscale spatial structures of craters in images in appropriate resolutions using optimum ...

Updated Interior Structure of Callisto From a Reanalysis of Galileo Data
Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.Abstract The internal structure of Callisto has been a long‐standing question since the Galileo mission. Previous analyses suggested a largely undifferentiated interior. We present an updated interior structure for Callisto derived from a reanalysis of Galileo's Doppler tracking data using new signal processing techniques.
