A million observers of the superbolide,k scrutinizing the sky; certainly, nobody had a camera at the ready. This explains why there are almost no photographs of the bolide before the moment of its explosion. An exception to this was one resident of Chelyabinsk, Marat Akhmetvaleyev, who was standing with a camera on the bank of the Miass一再遛 发表于 2025-3-29 12:41:37
The fate of the fiery serpent,he dragons were called firedrakes. The Chelyabinsk superbolide absolutely supports such a comparison. In this chapter, we will consider the evolution and features of the bolide caused by the fall of the Chelyabinsk meteorite in more detail.干涉 发表于 2025-3-29 17:14:14

Gorkavyi advised the recipients of those emails that a dust ring from the Chelyabinsk meteoroid’s remnants was forming around the planet. In order to calculate the parameters of that ring correctly, there was an urgent need to collect some du健壮 发表于 2025-3-30 00:02:28

Why the stone exploded,eteorite research indicate that the abrupt increase in energy release at altitudes between 45–25 km (kinetic explosion) was not the reason, but the consequence of its destruction. The destruction occurred because of mechanical stresses in the meteoroid, created by the air pressure and the reduction
