NASA warns that 87 million tonnes of apocalyptic asteroids could release 80,000 times more energy than the atomic bomb of Hiroshima if it collided with the Earth

  • If the asteroid, called Bennu, collided with the Earth, would be 80,000 times more powerful than the nuclear bomb of Hiroshima, fallen by the USA in August 1945
  • A probe captured a surprising image this week, showing that the Earth and the Moon are similar to a single point in the distance to asteroids of 87 million tons
  • NASA says there is one of 2,700 possibilities that the asteroid apocalypse collide with Earth in the next century
  • The OSIRIS-Rex probe will reach the surface of Bennu in 2020, where scientists hope to unlock the secrets of the formulation of human life

NASA has warned that the gigantic "apocalyptic asteroid" that captured in an impressive photograph could release 80,000 times more energy than the Hiroshima atomic bomb if it collides with the Earth, which can end such a life. as we know it

Named Bennu, the 500 foot rock is taller than the Empire State Building and it is estimated to be larger than 1,664 times the Titanic.

And scientists say that a collision with the Earth could have a cataclysmic effect on millions of lives.

But the space agency insists that immediate preparations will not be necessary, since it is not expected that the rock will fly near the planet until the next century.

Meanwhile, the NASA OSIRIS-Rex probe is orbiting the asteroid on an observatory mission, with plans to land on the surface in 2020.

The probe captured a surprising image this week, showing the Earth and the Moon similar to a single point in the distance to the asteroids of 87 million tons.

OSIRIS-Rex will collect samples from the rock before returning to the Earth, with the intention of helping to unlock some of the secrets behind the origins of human existence.

Scientists hope that the asteroid will help demonstrate a theory that billions of years ago that asteroids place with our planet transfer vital chemicals to the surface of the Earth, which causes them living organisms will formulate.

WHAT IS THE NASA FOUND?

The data obtained from the two spectrometers of the spacecraft, the visible and infrared spectrum OSIRIS-REx (OVIRS) and the OSIRIS-REx thermal emission spectrometer (OTES) reveal the presence of molecules containing atoms of & # Hydrogen oxygen and hydrogen, known as "hydroxyls." & # 39;

The team suspects that these hydroxyl groups exist globally through the asteroid in clay minerals with water, which means that at some time, the rocky material of Bennu interacted with the water.

While Bennu is too small to have liquid water lodged, the finding indicates that liquid water was present at some time in the primary body of Bennu, a much larger asteroid.

But Bennu, called "asteroid apocalypse", also poses a potential threat of extinction.

Scientists say that if Bennu collided with the Earth, the impact would release more energy than all detonated nuclear weapons in history.

However, NASA insists that the chances of colliding – around a 2.700 – are very thin, and humans probably live another day, even if they do.

But, on the contrary, if the rock challenges the odds, experts say that spacecraft designed by NASA to stop asteroids will probably not be effective against Bennu.

There may be hopes for his new adventure, the HAMMER – or the Asteroid Mitigation Mission with speed speed for the emergency response vehicle – that is designed to fly asteroids with nuclear bombs or direct the asteroid to another course.

However, experts say that probably a HAMMER is as ineffective as its predecessor against Bennu, unless you use the least favorable nuclear option.

"The consequences would be terrible," said Kirsten Howley, a physicist at the Lawrence Livermore National Laboratory, which is part of the planetary defense team.

The rock has a 2,700 chances of colliding with the planet between 2175 and 2199, according to NASA

For scientists, the launch of a deflector boat in Bennu could take up to seven and a half years.

And Howley thinks it is better to act before and after in precautionary preparation.

"The push you need to give is very small if you divert the asteroid for 50 years.

"The probability of a Bennu impact can be 1: 2,700 today, but this will change almost, better or worse, as we accumulate more data on its orbit.

"The delay is the greatest enemy of any asteroid diversion mission," he said.

HOW IS THE MISSION OF OSIRIS-REX OF NASA WHAT IS THE WORK OF ASTEROID?

Osiris-Rex is the first US mission designed to return an asteroid piece on Earth.

Scientists say that the old asteroid could have clues about the origin of life.

It is believed to have formed 4,500 million years ago, a remnant of the building blocks of the solar system.

The spacecraft launched on September 8, 2016 at 19:05 EST aboard an Atlas V rocket.

After a careful Bennu study to characterize the asteroid and locate the most promising sample sites, Osiris-Rex will collect between 2 and 70 ounces (approximately 60 to 2,000 grams) of surface material with the Its robotic arm will return the sample to the Earth through a removable capsule in 2023.

To capture samples on the surface, the boat will scroll over a specific area and will ship it very slowly and smoothly & # 39; 4 centimeters (10 cm) per second.

The ship will also carry a laser altimeter, a set of cameras provided by Arizona University, spectrometer and lidar, which is similar to radar, which uses radio waves instead of radio waves to measure the distance.
