Can astronauts on the space station survive an asteroid strong enough to extinction humanity?

The International Space Station orbits the Earth at an altitude between 370 and 460km. Its flight speed is calculated at about 7.7 km / s, completing an orbit every 92.68 minutes – about 15.54 rounds in a day.

Flight trajectory of the International Space Station

The 12km wide meteorite Chicxulub Impactor hit Mexico’s Yucatan peninsula about 66 million years ago crashed into the Earth’s crust at 40 times the speed of sound, creating an explosion equivalent to 100 trillion tons. TNT – simultaneously pushing the ocean floor to a depth of 500m, creating a 180km wide pit with a 300m tsunami. The explosion was so loud that it created a quake of magnitude 10 and fired debris into space. It even causes the foot bones of living things on Earth to crash straight into their bodies – and cause 75% of the organism to become extinct.

Chicxulub Impactor – the reason dinosaurs are living in museums.

If a similar sized meteorite were to hit Earth, it would surely cost billions – but not enough to eradicate humans – with more scientific technology and endurance than dinosaurs from. old time.

With a meteorite sufficient to make humanity extinct, scientists have calculated that it must have a width of at least 96km. Assuming it is made up of rock, and crashes into the sedimentary layer of the earth’s crust at a speed of 20km / s, it can create a crater of more than 800km and more than 2km deep. Even if it is made up of iron – which is denser than rock – the pit has a radius of up to 1200km wide.

The amount of heat generated from this explosion will be enough to completely burn everything within hundreds of kilometers around the impact point, and a magnitude 10 earthquake will flatten everything in sight.

The model simulates the radius of the 800km pit created by a 96km wide rock meteor.

At the speed of the ISS, a collision with the rock thrown from the explosion, if not destroyed, is enough to paralyze the space station. What’s more, with 15.54 revolutions per day, the ISS will always fly over debris clouds – increasing the chance of colliding with those objects.

Many debris will be shot into the air at an altitude of hundreds of kilometers

If that happened, the astronauts would lose consciousness for 11 seconds after the pressure subsided before the body was disgusted:

1. The body will relax.

2. The liquid will turn into gas.

3. Nitrogen in the blood will form bubbles, like when diving into the deep sea, leading to extreme pain.

4. The blood will gradually boil.

5. The lungs will be crushed and bleed because of the difference in pressure between inside and outside the body.

6. Eventually, they will die from suffocation.

If the space station is lucky enough, these astronauts will have to choose between burning Earth or staying in a distant but safe universe.

Naturally, without supplies from NASA or international space centers, they wouldn’t be able to survive long. And of course, if returning to Earth, there is no source of food and water anymore because it was all burnt in the fire.

The ships used to separate from the space station are hidden with the names Soyuz, HTV and Progress.

For now, if that happens to Earth right now, the last humans will be the current ISS crew:
