Large impact cratering during lunar magma ocean solidification [PDF]
Nature Communications, 2021 Lunar impact basins formed during the magma ocean solidification should have formed almost unidentifiable topographic and crustal thickness signatures, thus may escape detection.

Constraining surface properties of asteroid (162173) Ryugu from numerical simulations of Hayabusa2 mission impact experiment [PDF]
Nature Communications, 2022 Hayabusa2 mission impact experiment on asteroid Ryugu formed a crater larger than expected. Here, the authors show numerical impact simulations and find that the target cohesion may be very low, indicating the Hayabusa2 impact experiment probably ...

Hydrothermal activity generated by impact melt emplacement on the rim of Ritchey crater, Mars [PDF]
Nature CommunicationsImpact-induced hydrothermal systems have the potential to sustain long-lived aqueous environments throughout the history of Mars, yet their nature and distribution are not well-understood.

Cepstrum Analysis of Terrestrial Impact Crater Records [PDF]
Journal of Astronomy and Space Sciences, 2008 Study of terrestrial impact craters is important not only in the field of the solar system formation and evolution but also of the Galactic astronomy. The terrestrial impact cratering record recently has been examined, providing short- and intermediate ...

Time/Frequency Analysis of Terrestrial Impack Crater Records [PDF]
Journal of Astronomy and Space Sciences, 2006 The terrestrial impact cratering record recently has been examined in the time domain by Chang & Moon (2005). It was found that the ˜ 26 Myr periodicity in the impact cratering rate exists over the last ˜ 250 Myrs.

Self-Secondaries Formed by Cold Spot Craters on the Moon
Remote Sensing, 2021 Self-secondaries are a population of background secondaries, and they have been observed on top of impact melt and ballistically emplaced ejecta deposits on various planetary bodies.

Pluto's Antipodal Terrains Imply a Thick Subsurface Ocean and Hydrated Core
Geophysical Research Letters, 2021 Recent analysis of New Horizons data revealed an ∼1,000‐km‐diameter region of large‐scale lineations antipodal to Sputnik Planitia, the 1,200 × 2,000 km elliptical impact basin on Pluto's anti‐Charon hemisphere.
