The Massalia Asteroid Family As The Origin Of Ordinary L Chondrites
Studies of micrometeorites in mid-Ordovician limestones and Earth’s impact craters indicate that our planet witnessed a massive infall of ordinary L chondrite material 466 million years (My) ago (Heck et […]

Relative Contribution From Comets And Carbonaceous Asteroids To Earth’s Volatile Budget In The Context Of An Early Instability
Recent models of solar system formation suggest that a dynamical instability among the giant planets happened within the first 100 Myr after disk dispersal, perhaps before the Moon-forming impact. As […]

Away Team Idea: New Evidence On The Lost Giant Chinguetti Meteorite
The giant Chinguetti meteorite that Gaston Ripert reported seeing in 1916 has never been found. A radionuclide analysis by Welten et al (2001) of the 4.5kg mesosiderite that Ripert recovered, […]

Chondrule Formation During Low-Speed Collisions of Planetesimals: A Hybrid Splash-Flyby Framework
Chondrules probably formed during a small window of time ∼1-4 Ma after CAIs, when most solid matter in the asteroid belt was already in the form of km-sized planetesimals.
