Chelyabinsk Meteorite in a spherical glass box.
For exactly 32.5 seconds, this spacecraft travelled through the atmosphere at a speed of about 19 km/s (68,400 km/h), ignited and consumed to a large extent, then exploded violently in the form of an intense flash of blinding light, even more luminous than the Sun. It then disintegrated into pieces that exploded themselves. It weighed 13,000 tonnes and was 20 metres long. Only 4 to 5 tons reached the ground, making more than 1,000 injured! This fragment is oriented: it has melted into space, becoming more pointed at the front. as it broke on the ground, we see the inside with many darker veins: a first collision probably torn it off the asteroid belt of Flora between Mars and Jupiter. It’s the first meteorite of the Youtube era!
