Abstract The identification of lobate debris deposits in Arabia Terra, along the proposed paleoshoreline a former northern ocean, has renewed questions about existence and stability ocean‐sized body water early geologic history Mars. potential occurrence impact‐generated tsunamis ocean was investigated by comparing geomorphologic characteristics Martian with predictions well‐validated terrestrial models (scaled to Mars) tsunami wave height, propagation direction, runup elevation, distance...
Direct links between carbonaceous chondrites and their parent bodies in the solar system are rare. The Winchcombe meteorite is most accurately recorded chondrite fall. Its pre-atmospheric orbit cosmic-ray exposure age confirm that it arrived on Earth shortly after ejection from a primitive asteroid. Recovered only hours falling, composition of largely unmodified by terrestrial environment. It contains abundant hydrated silicates formed during fluid-rock reactions, carbon- nitrogen-bearing...
Context . The source regions of ordinary chondrites (~80% all falls) and large S-type near-Earth objects (NEOs; ~30%) have recently been identified with three young asteroid families (Karin, Koronis, Massalia) being at the origin most chondrite falls. Aims present work is a continuation our previous studies aims to determine remaining meteorite NEO classes, an emphasis on carbonaceous (CM, CI, CO, CV, CK, CR, CH, CB, or C-ungrouped). Methods We studied 38 individual families, including old...
Context. Since August 2014, the OSIRIS Narrow Angle Camera (NAC) onboard Rosetta spacecraft has acquired high spatial resolution images of nucleus comet 67P/Churyumov-Gerasimenko, down to decimeter scale. This paper focuses on Imhotep region, located largest lobe nucleus, near equator.
Context. Asteroid modeling efforts in the last decade resulted a comprehensive dataset of almost 400 convex shape models and their rotation states. These already provided deep insight into physical properties main-belt asteroids or large collisional families. Going finer detail (e.g., smaller families, with sizes ≲20 km) requires knowledge parameters more objects.
In the eastern part of Arabia Terra cratered boundary, lobate deposits are observed on top north-sloping highland mesas. Our previous studies (Rodriguez et al., 2016; Costard 2017) suggest that most plausible origin for these morphologies tsunami associated with Lomonosov impact event in an Hesperian age ocean (Costard 2019). Tsunami Earth serve as valuable analogs interpreting possible tsunami-related features Mars, especially regarding hypothesized ancient oceans. this study, we examine...
Farside Explorer is a proposed Cosmic Vision medium-size mission to the farside of Moon consisting two landers and an instrumented relay satellite. The unique scientific platform in that it shielded from terrestrial radio-frequency interference, recorded primary differentiation evolution Moon, can be continuously monitored Earth–Moon L2 Lagrange point, there complete lack reflected solar illumination Earth. will exploit these properties make first radio-astronomy measurements most...
Abstract The formation and differentiation of the crust Mars in first tens millions years after its accretion can only be deciphered from incredibly limited records. martian breccia NWA 7034 paired stones is one them. This meteorite contains oldest igneous material ever dated: ~4.5 Ga old. However, source geological context have so far remained unknown. Here, we show that was ejected 5–10 Ma ago north-east Terra Cimmeria—Sirenum province, southern hemisphere Mars. More specifically, belongs...
What was the nature of Late Hesperian climate? Warm and wet or cold dry? Formulated this way question leads to an apparent paradox since both options seem implausible. A warm climate would have produced extensive fluvial erosion but few valley networks been observed at age late Hesperian. too kept any northern ocean frozen most time. moderate transferred water from land in form snow ice. But prevent tsunami formation, for which there is some evidence. Here, we provide new insights numerical...
Abstract This work in Utopia Planitia is the first continuous regional mapping of ice‐related landforms integrated into an effort to study three main basins (Arcadia, Acidalia, and Planitiae) northern plains. The distribution morphotypes these landforms, SHAllow RADar detections, crater size‐frequency measurements (>50 m diameter) were used understand permafrost cryolithology its past evolution relation climate Planitia. Three assemblages identified based on their spatial correlation with...
ABSTRACT Two meteorite pieces have been recovered in Italy, near the town of Cavezzo (Modena), on 2020 January 4th. The associated fireball was observed evening New Year’s Day by eight all-sky cameras PRISMA network, a partner FRIPON. computed trajectory had an inclination angle approximately 68° and velocity at infinity 12.8 km s−1. Together with relatively low terminal height, estimated as 21.5 km, those values were indicating significant possibility dropping event, additionally confirmed...
Determining the source regions of meteorites is one major goals current research in planetary science. Whereas asteroid observations are currently unable to pinpoint most meteorite classes, meteors with camera networks and subsequent recovery may help make progress on this question. The main caveat such an approach, however, that rate falls low, implying meteoritic analogues at least 80% observed remain unknown. Aims: Spectroscopic bolides have potential mitigate problem by classifying...
Abstract Recent research suggests that major meteorite impact events into a Late Hesperian/Early Amazonian ocean likely produced mega‐tsunami would have resurfaced coastal areas in northwestern Arabia Terra. The orientations of the associated lobate deposits, conspicuous type landforms called Thumbprint Terrain, if an event triggered mega‐tsunami, most location source crater is within northern plains regions situated north This study focuses on identification craters impacted and are to...
