On the persistency of crater assignment criteria for Stromboli explosion-quakes
Annals of Geophysics, 1996 On the basis of the results of previous works by our group, this paper aims to investigate the correlation between features of a kind of seismic events recorded at Stromboli (the so called explosion-quakes) and the source of such explosions, i.e.

A Multi-Annotator Survey of Sub-km Craters on Mars
Data, 2020 We present here a dataset of nearly 5000 small craters across roughly 1700 km2 of the Martian surface, in the MC-11 East quadrangle. The dataset covers twelve 2000-by-2000 pixel Context Camera images, each of which is comprehensively labelled by six ...

Geology of the Debussy quadrangle (H14), Mercury
Journal of Maps, 2021 Mercury’s Debussy Quadrangle (H14) lies between 0–90° E and 22.5–65° S. Here we use MESSENGER data to produce the first geological map of this quadrangle at a scale of 1:3,000,000, based on linework completed at a scale of 1:300,000.

Vision‐based crater and rock detection using a cascade decision forest
IET Computer Vision, 2019 Both crater and rock detection are components of the autonomous landing and hazard avoidance technology (ALHAT) sensor suite, as craters and rocks represent the majority of landing hazards.

Impact crater degradation, Oxia Planum, Mars
Journal of Maps, 2021 The main goal of the European Space Agency (ESA) and Roscosmos ExoMars rover mission is to collect samples from the near-subsurface of Mars. The rover will look for any physical or chemical evidence of ancient life in the near subsurface.

Determination of the Size and Depth of Craters on the Moon
Center for Educational Policy Studies Journal, 2018 Experimental work in the research of astronomical phenomena is often difficult or even impossible because of long-lasting processes or too distant objects and correspondingly too expensive equipment.

Characterization of the Candidate Landing Region for Tianwen‐1—China's First Mission to Mars
Earth and Space Science, 2021 This paper presents our efforts to characterize the candidate landing region (109°–133°E, 23°–30°N) for Tianwen‐1, China's first mission to Mars, in terms of engineering safety and scientific significance. Topographic analysis reveals that the region has

A Machine Learning Approach to Crater Classification from Topographic Data
Remote Sensing, 2019 Craters contain important information on geological history and have been widely used for dating absolute age and reconstructing impact history. The impact process results in a lot of ejected fragments and these fragments may form secondary craters ...

Pitted terrains on (1) Ceres and implications for shallow subsurface volatile distribution
Geophysical Research Letters, 2017 Prior to the arrival of the Dawn spacecraft at Ceres, the dwarf planet was anticipated to be ice‐rich. Searches for morphological features related to ice have been ongoing during Dawn's mission at Ceres.
