TL;DR: A global survey of airbursts of a kiloton or more is performed, and it is found that the number of impactors with diameters of tens of metres may be an order of magnitude higher than estimates based on other techniques, which suggests a non-equilibrium in the near-Earth asteroid population.

TL;DR: In this paper, the authors predict the rate at which meteoroids impact and damage spacecraft, using environment models that describe the environment conditions and meteoroid trajectories in low Earth orbit (LEO).

TL;DR: In this paper, the mass index of the Camelopardalid meteor shower was found to be 2.17 ± 0.04, indicating that large Camelopardalids are weak agglomerations of more refractory grains, which are easily disrupted in space and keep the shower supplied with small material and depleted in large material.

TL;DR: In this article, the authors measured optical meteor fluxes for the 2015 Perseid meteor shower as seen by the Meteoroid Environment Office's eight wide-field cameras and reported that the peak Perseid flux on the night of August 13, 2015, was measured to be 0.002989 meteoroids/km2/hr down to 0.00051 grams, corresponding to a ZHR of 100.7.

TL;DR: The Chelyabinsk superbolide of February 15, 2013, was caused by the atmospheric entry of a ~19 m asteroid with a kinetic energy of 500 kT TNT just south of the city of Chelyabainsk, Russia as discussed by the authors.
