Abstract From 1974 to 1975, the Mariner 10 spacecraft studied Mercury's environment during three flybys and detected hydrogen, helium, and possibly atomic oxygen in the exosphere using its ultraviolet spectrometer, but no molecular hydrogen. Based on the sensitivity of the occultation instrument, an upper limit for the H2 ${\mathrm{H}}_{2}$ surface ...

Measuring the meteoroid environments of the planets with meteor detectors on Earth
We describe how meteors recorded at the Earth can be used to partly reconstruct the meteoroid environments of the planets if a large sample (i.e. millions of orbits at a minimum) is available.

Abstract The flux of solar system meteoroids is dominated by objects less than 1 mm in diameter whose impact effects play a major role in the space weathering of airless body surfaces. These effects remain poorly characterized with respect to their dependence on the range of impact speeds for meteoroids across the inner solar system.

Abstract The study of terrestrial lava tubes is essential for understanding geological processes occurring during volcanic activity on other planetary bodies, such as Mars. These processes lead to the formation of minerals analogous to those found on other planets.

Drelów, the 13th and latest meteorite fall in Poland—A typical L6 chondrite with shock veins
Abstract On Tuesday, February 18, 2025, at 18:04:14 local time, residents of Poland observed a bright fireball registered by many Polish fireball stations belonging to the Skytinel Network established a few months before by Mateusz Żmija. Thus, the meteoroid's orbit, atmospheric trajectory, and the strewn field were calculated, and over 70 fragments ...

Al‐Khadhaf: The first camera‐observed (H5–6) meteorite fall from Oman
Abstract A fireball camera system installed in 2022 by the Oman Meteorite Monitoring Project (OMMP) as part of the Global Fireball Observatory (GFO) recorded a 3.2 s fireball on March 8, 2022 at 8:15 p.m. UTC. A meteoroid of 4 ± 2 kg entered the atmosphere at 14.0 km/s.
