A giant fire exploded in December with a force 10 times higher than the energy released by Hiroshima's atomic bomb. The information was now published by NASA at a US conference.

A massive fireball exploded in the Earth's atmosphere in December
NASA This is the second largest collapse in 30 years ago, and the largest from the one happened in Chelyabinsk, Russia, six years ago.

However, there was no awareness of the event so far as it happened across the Bering Sea, on the Russian peninsula of Kamchatka.

When it erupted, the space rock generated 10 times more energy released by Hiroshima's atomic bomb. Lindley Johnson, the NASA planet protection officer, said less explosions only do two or three times every 100 years.

Water shield

Around midday, on the local occasion, on December 18, the asteroid went over the water at a distance of 32 km / s, on a seven-legged path.

The meteor exploded, from a meter-reach, 25.6 km from the Earth's surface, with an impact of 173 kilotons. "That's equal to 40% of the energy released in Chelyabinsk, but as it happened over the Bering Sea, it didn't have the same effect and it didn't appear in the news," said Kelly. T Fast in the visual program near Earth. of NASA.

"That's another thing we have for our protection: the planet is full of water." Fast talked about the event during the 50th Lunar and Science Science Conference that is taking place in Woodlands, USA, between 18 March and 22.

"Problems without passports"

Military satellite found the explosion last year and the US Air Force sent this information to NASA.

Johnson explained that the fireball had spread through an area near the routes that commercial planes travel between North America and Asia.

For this reason, researchers have been in contact with various aircraft to check whether or not they have seen the event.

In 2005, Congress called NASA to find out about 2020 90% of the asteroids near Earth, reaching 140 meters or more.

Rock rocks of this size have been called "rocks without pastes" as they are predicted to affect whole regions if they fall into Earth. However, scientists believe this work will take at least another 30 years.

Once something is near to be identified, NASA has succeeded where it is happening, based on accurate data on its orbit.

For example, in June 2018 the observatory was found in Arizona, the United States, eight hours that was in 2018, before it affected it.

The Center correctly located near Land Surveys at NASA's Jet Wash Laboratory (JPL), and its data was used to determine the most likely habitat for operations.

The information showed that rock could have an effect on southern Africa. As calculations appear, the fireball was recorded with farm security cameras above the Botswana air. Later, pieces of the space were found in the area.

Examination

The most recent explosion, however, demonstrates that large particles can hit the Earth without warning, which highlights the need to improve monitoring methods.

In 2005, Congress asked NASA to reach by 90% of the asteroids near Earth, reaching 140 meters or more.

A stronger vision network will rely only on telescopes on Earth but also on watch areas in a locality. A project developing it is calling for a telescope to be launched called NeoCam to the point where hazardous asteroids greater than 140 meters can be identified and celebrated.

"The idea of ​​getting as much as possible is the goal that Congress has proposed NASA 90% of the asteroids near the Earth to find 140 meters or more," said Amy Mainzer, prime minister. scientist NeoCam JPL project.

If the microscope does not fit into space, projections show it will take decades to reach this goal with the devices now available in the region. Although the researcher is adding to it, it may be faster with undercurrent telescope.
