Propellants, Explosives, Pyrotechnics, Volume 51, Issue 3, Page 446-455, March 2026.A low‐speed impact (around one meter per second) of a metallic tip on an explosive confined by a thin plate is simulated. The heat due to friction between the tip and the plate and the one due to the deformation of the plate are not transfered to the ignited zone.

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.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.

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract Previous observations have demonstrated that rocket exhaust can trigger ionospheric electron density holes and cause electron temperature enhancements during launches. Using high‐precision measurements from the Sanya incoherent scatter radar, we discovered a previously overlooked decrease in electron temperature.
