Counting impact craters on surfaces of terrestrial bodies is currently the only way to estimate the age of a planetary surface and the duration of geological processes occurred in the past. This approach requires a tedious mapping and morphological inspection of a large number of impact craters. We created a Crater Detection Algorithm trained on Martian orbital imagery in order to compile all...
Introduction: A thin section of howardite Dhofar 018 preserving an pristine radial pyroxene chondrule has been analysed in order to constrain ejecta blanket conditions on asteroid 4 Vesta. This meteorite is known to contain clasts and fragments of exogenic material, including ordinary and chondrites, enstatite meteorites, and ureilites [1]. However, a single intact chondrule has yet to be...
The lunar cratering record is traditionally used to constrain the bombardment history of both the Earth and the Moon. It was suggested from different perspectives, including asteroid dynamics, lunar Apollo samples, impact simulations, and lunar evolution modelling, that the Moon could be missing evidence of its earliest cratering record. Recent studies suggested that lunar magma ocean (LMO)...
Martian meteorites are mostly igneous, with only one notable exception, which still contains igneous clasts. Within the igneous samples that have not undergone brecciation, crystallographic textures can be used to infer the environment of emplacement, such as is commonly applied to terrestrial igneous rocks. Such textures have already been used to deduce the igneous setting for the Martian...
Extremely long-lived fireball events have been described previously in scientific literature, the first of which being the Great Daylight Fireball of 1972 (Ceplecha, 1979; 1994). Since then, there have been several similar grazing events reported. In just four years of operation of the Desert Fireball Network (DFN), the largest fireball network in the world, we have recorded two skipping...
The NASA’s InSight mission has placed the seismometer SEIS less than a year ago on the surface of Mars. SEIS was designed to detect planet’s seismic activity. One of the suspected seismic sources could be meteorite impacts. It was been previously estimated that impacts forming up to 30 m diameter craters could be detected by SEIS. They are large enough yet frequent enough to occur during the...
There are ~130 confirmed Martian meteorites, yet their source craters on Mars still remain unknown. Locating their source craters would be extremely significant in providing geological context to the only samples from Mars that we have. Geological context is essential if we wish to fully develop our understanding of these meteorites, and therefore develop our understanding of Mars and...
The Desert Fireball Network (DFN) is the world’s largest fireball camera network and is located in the Australian outback. It consists of 52 observatories, covering an area of 3 million km$^2$ aimed to detect fireballs, recover meteorites and to calculate their orbits [1]. The observatories are optimised to image 1-100 m size objects having a brightness between 0 to 15 magnitudes [1].
The aim...
