<p>October 31st of 2015 the bolide lightened up the sky above Northern Poland. The main purpose of the project&#160; was to define the place and time of its explosion in Earth&#8217;s atmosphere. To calculate these values and define the velocity of acoustic wave in the air, MATLAB model has been created. The model

One of the interesting applications of a classical problem on movement of a solid body in resistant media is considered which is connected to estimation of trajectories of space bodies such as meteorites in the atmosphere of the Earth (or other planets). One feature of these objects is the absence of their “correct” form.

The Modeling of Bolide Terminal Explosions
Earth, Moon, and Planets, 2004The phenomenon of terminal thermal explosions of bolides is considered and mathematically modeled, using the mechanisms of ablation and fragmentation due to mechanical and thermal stresses. The definition and criterion of thermal explosions are given.

Meteoroid, Bolide and Meteorite «Chelyabinsk»
Materials Science Forum, 2016This paper presents the brief review of Chelyabinsk group of meteoroid, bolide and meteorite "Chelyabinsk" investigations. Height of the maximum of the main flash of Chelyabinsk bolide is 30 km. Only 1% of meteoroid mass arrived to the Earth surface in the form of meteorites while the most part of meteoroid became dust.

The stratigraphic record is punctuated by episodes of mass extinction; these must be accounted for by major changes in the evolution of the Earth. Three groups of forces have acted on the Earth through time and may be adduced as the ultimate causes of many geological phenomena—including extinctions.

Avvistata due sere fa da sette fotocamere della rete Prisma mentre solcava i cieli della Toscana, la meteora si è spenta a circa 80 km di quota. L’alta velocità di ingresso in atmosfera e la significativa eccentricità dell'orbita inducono a ritenere che abbia un’origine ...

IMPACT! - BOLIDES, CRATERS, AND CATASTROPHES
Elements, 2012It is now universally accepted that the impact of planetesimals, asteroids, and comets has been a fundamental process throughout the Solar System. Catastrophic impact events have been instrumental in developing the early history of the planets and have caused environmental disasters throughout Earth history.
