NASA satellite collided with the asteroid – NRK Nordland

Sometimes Hollywood comes out before NASA.

Like in the 1998 movie Armageddon with Bruce Willis and Ben Affleck. So a Texas-sized asteroid is on a collision course with Earth.

Of course, that’s no good – and the only thing that can save humanity is for NASA to send Harry S. Stamper, played by Bruce Willis, to try to destroy the threat.

You almost have to see for yourself how it goes.

Now, 24 years later, NASA will do almost the same thing as Armageddon.

NASA calls it planetary defense

Tonight, now in Norway, a satellite will crash into a 140-meter asteroid with a name Abode.

The satellite, launched 11 months ago, weighs 570 kilograms and will strike at a speed of 22,000 kilometers per hour.

It has now flown 11 million kilometers away from Earth.

The aim is to find out if it is possible to change the orbit of the asteroid.

For those who are more interested, it is possible follow the event live here.

NASA itself calls it planetary defense.

– The biggest difference from Armageddon is that this asteroid is not on a collision course with Earth, reassures Yngvild Linnea Andalsvik.

He is in charge of space monitoring at the Norwegian Space Center and one of those who will stay awake tonight to follow the drama live.

– It’s the first time it’s done, he says.

The threat from an asteroid is one of the few natural disasters we can predict, says the specialist.

– So it is important to perform some tests before eventually discovering an asteroid that will hit the Earth.

– Many unknown asteroids

But how big is the chance that a large asteroid will hit the Earth?

In 2005, NASA received a mandate from Congress to find 90 percent of the near-Earth asteroids that are large enough to destroy a city – those that are 140 meters or more in diameter, he writes. New York Times.

But Congress never gave NASA the money to finish, so the task is only half done, with about 15,000 more asteroids to discover.

– You have good control over the larger asteroids – and the smaller ones aren’t too dangerous – but it’s the intermediate ones that worry you the most, says Andalsvik.

He says the researchers have made good calculations of the asteroids that are already known and their trajectories 100 years into the future – and none of them pose much of a danger.

– Those who have not yet been discovered are the big question.

1200 injured when the meteoroid hit Russia

And we don’t actually have to go back many years to find a celestial body that has damaged the Earth.

In 2013, one arrived

A meteoroid is a relatively small object in the solar system. The size can range from the size of a grain of sand and up to 900 meters in diameter. Meteoroids are fragments of asteroids or dwarf planets, particularly from the asteroid belt between Mars and Jupiter, which break free from the parent body and enter orbit around the Sun. The orbit can be irregular and cross or collide with the orbits of the planets .

“data-term =” meteoroid “> meteoroid in the Earth’s atmosphere over the Ural region in Russia.

According to Russo authorities, about 1,200 people were injured.

Russian scientists estimated the meteorite to weigh around ten tons, reports the AP news agency.

The researchers also believed that the meteorite hit the atmosphere at a speed of about 54,000 kilometers per hour.

The pressure wave from the fireball spread to the ground where extensive damage to buildings occurred.

A quarter of an hour after the meeting, earthquakes were also recorded in Norway.

The energy released is estimated to be between 26 and 33 times the power of the US atomic bomb used on the Japanese city of Hiroshima in 1945.

He has to take measurements

Yngvild Linnea Andalsvik says that the measurements will be made already tonight, to find out how great the impact of the satellite was on Abode.

– But later ESA, the European Space Agency, of which Norway is a part, will send a satellite that will make more accurate measurements.

The most exciting thing now is if the satellite manages to hit. It has an automatic navigation system that guides it to the asteroid.

– This is one of the few times it is a good sign that you are no longer receiving signals from a satellite, concludes Andalsvik.
