NASA warns that 87 million tons of apocalypse asteroid & # 39; 80,000 times more energy than the atomic bomb of Hiroshima when it collides with the earth
- If the asteroid, named Bennu, hit the earth, it would be 80,000 times more powerful than the nuclear bomb of Hiroshima, which was dropped by the US in August 1945
- A probe captured an astonishing picture this week and showed the earth and the moon as a dot in the distance to the asteroid of 87 million tons
- NASA says there is a probability of 2,700 that the & apos; apocalypse asteroid & # 39; the next century with the earth collides
- The OSIRIS-Rex probe will land on the surface of Bennu in 2020, where scientists hope to unlock the secrets behind the formulation of human life.
NASA has warned that the giant "apocalypse asteroid & # 39; which he recorded on an astonishing photo could give off 80,000 times more energy than the atomic bomb of Hiroshima if it collided with the earth – which could possibly put an end to life as we know it.
Nominated Bennu, the 500 foot rock is longer than the Empire State Building and is estimated at 1,664 times heavier than the Titanic.
And scientists say that a collision with the earth can have a cataclysmic effect on millions of lives.
But the space agency insists that no more doom thinking preparations will be necessary, because the rock is not expected to fly close to the planet until the next century.
In the meantime, NASA & # 39; s OSIRIS-Rex probe is currently revolving around the asteroid during an observation mission, with plans to land on the surface in 2020.
The probe captured an astonishing picture this week and showed the earth and the moon as a dot in the distance to the asteroid of 87 million tons.
OSIRIS-Rex collects samples from the rock before returning to earth, hopefully helping to unlock some of the secrets behind the origins of human existence.
Scientists hope that the asteroid will help to prove a theory that billions of years ago asteroids colliding with our planet transferred essential chemicals to the surface of the earth, inducing living organisms to formulate.

WHAT TO FIND NASA?
Data obtained from the two spectrometers of the spacecraft, the OSIRIS-REx Visible and Infrared Spectrometer (OVIRS) and the OSIRIS-REx Thermal Emission Spectrometer (OTES), reveal the presence of molecules that contain oxygen and hydrogen atoms that are bound together, also well & # 39; hydroxyls & # 39; called. & # 39;
The team suspects that these hydroxyl groups exist globally over the asteroid in water-bearing clay minerals, which means that Bennot's rocky material interacted with water at one point.
Although Bennu itself is too small to ever receive liquid water, the finding does indicate that at some point liquid water was on Bennu's parent body, a much larger asteroid.
But Bennu, also called the apocalypse asteroid & # 39; a potential threat of extinction.
Scientists say that if Bennu hits the earth, the impact would release more energy than all nuclear weapons that have exploded in history.
But reassuringly, NASA maintains that the probability that it clashes – around one at 2,700 – is very small, and that people will probably see another day, even if that is the case.
But on the contrary, if the rock proves the contrary, experts say that the spacecraft designed by NASA to stop asteroids are not likely to be effective against Bennu.
There is hope for their newest venture, the HAMMER or Hyper-velocity Asteroid Mitigation Mission for Emergency Response Vehicle – designed to inflate asteroids with atomic bombs or to steer the asteroid on a different path.
However, experts say that only one HAMMER is probably as ineffective as its predecessor against Bennu – unless the less favorable nuclear option is used.
"The consequences would be terrible," said Kirsten Howley, a physicist from the Lawrence Livermore National Laboratory who is part of the planetary defense team.
HOW WILL THE NASIRIS OSIRIS REX MISSION SAMPLE TAKE OFF A ASTEROID WORK?
Osiris-Rex is the first American mission designed to bring a piece of asteroid to Earth.
Scientists say that the old asteroid could contain clues about the origin of life.
It is thought that it was formed 4.5 billion years ago, a remnant of the building blocks of the solar system.
The spacecraft was launched on board an Atlas V rocket on September 8, 2016 at 7:05 pm EST.
After a careful study by Bennu to characterize the asteroid and localize the most promising sample sites, Osiris-Rex will collect surface material with its robotic arm between 2 and 70 ounces (about 60 to 2,000 grams) and the sample via a removable capsule in 2023 .
In order to catch samples on the surface, the vessel floats over a certain area and it becomes' with a very slow and gentle & # 39; speed of 10 centimeters per second down.
The spacecraft will also carry a laser altimeter, a series of cameras supplied by the University of Arizona, spectrometers and lidar, similar to radar, with light instead of radio waves to measure the distance.
The rock has a 2700 chance to collide with the planet between 2175 and 2199, according to NASA
Current defense methods designed by the aerospace company would probably not be effective against the giant Bennu according to experts
For scientists, the launch of only one deflector boat to Bennu could take up to seven and a half years.
And Howley is of the opinion that it is better to take precautionary preparations earlier than in the past.
• The nudge you need to give it is very small when you divert the asteroid 50 years.
The probability of a Bennu impact can be 1 in 2700 today, but that will almost certainly change – in a positive or negative sense – as we gather more data about his job.
"Delay is the biggest enemy of any asteroidal deflection mission," she said.
