NASA is preparing for Armageddon with planetary defense exercises on a table



NASA conducts planetary defense exercises to see what happens if the apocalyptic space rock hits directly on Earth.

Participants will discuss potential preparations for studying an asteroid or comet, as well as how to repel and reduce damage caused by any impact.

The space agency has been scanning the sky for more than 20 years, searching for what it calls objects near Earth (NEOs).

NEOs are asteroids and comets orbiting the sun and coming within 30 million kilometers of orbit on Earth.

The threat of the impact of asteroids in recent years has increased, especially after the fiery ball in Chelyabinsk since 2013.

The meteor, which flashed across the southern Ural Mountains in February 2013, was the largest recorded meteor strike in more than a century after the 1908 event in Tunguska.

More than 1,600 people were injured by a blast from a blast that is estimated to be as strong as 20 atomic bombs in Hiroshima.

In preparation for a possible impact, NASA and other international scientific organizations will participate in the planetary defense conference 2019 next week.

A "mass exercise" will perform realistic, but imaginary scenarios for the asteroid and comet on a shock trajectory with the Earth.

The NEO impact scenario has been developed by the NEO (CNEOS) Center for Testing at NASA's Laser Reaction Center.

The asteroid scenario begins with the assumption that on March 26, astronomers discovered "an asteroid that they think potentially dangerous to the Earth.

After a "couple of months" of monitoring, observers predict that this NEO – called 2019 PDC – will pass through 0.05 Earth's aurora units (AU).

One AU is the distance between the Earth and the Sun and is equal to 92,955,807 miles (149,597,871 km).

In a fictional simulation, NASA claims that the asteroid is one of the 100 chances of colliding with Earth and that it can land on April 29, 2027.

First, it is 57 million kilometers from Earth and approaches 31,000 km / h (14 kilometers per second) and gradually becomes brighter.

Observing weeks have found it more and more likely that it will affect the Earth in 2027, but the details of the shape, size and composition of the asteroid remain unattainable.

It's all known that the average size of the asteroid can be anywhere from 330 meters to 1000 meters (100 meters to 300 meters).

More than a month after the first observed, it continues to fly to Earth and passes through the Earth at a distance of 0.13 au on May 13, 2019. The next one is expected to return near Earth in 2027.

The conference will take the event at this time and decide on the best way of doing it.

Experts will discuss the dangers posed by NEOs and activities that could be taken to deflect the threatening object.

"These exercises really helped us in the planetary defense community to understand what our colleagues should know on the disaster management side," said Lindley Johnson, NASA's Planetary Defense Director.

"This exercise will help us develop more effective communications between ourselves and our governments."

This diagram zooms into the intersection point of the orbits and shows the uncertainty in the predicted position of the asteroid (red spots reveal potential sites where the asteroid passes through the Earth). The region of uncertainty is several times longer than the diameter of the orbit of the moon but will decrease as more data on the path and trajectory of the asteroid

The conference will also discuss a hypothetical comet scenario.

This fictional event states that the comet was spotted on April 4, 2019 and could collide with the Earth on February 28, 2021.

It has an orbital period believed to be several thousand years old and astronomers speculate that its core is probably only about 0.62 miles (1 km) in size.

NASA has announced in recent weeks measures of hope to help combat the threat posed by NEO.

On April 11, the space agency announced that its radical mission to fire small spacecraft directly into the asteroid now has SpaceX on the list.

He chose Elon Mask's airline to launch its mission for a double diverting asteroid (DART), which will be erected in June 2021.

The wonderful mission will be the first demonstrated attempt to deter an asteroid by deliberately breaking the object into it at high speed.

Following the launch of Vandenberg's base in California at the Falcon 9 airborne base in 2021, Dartsoft is expected to reach the Didimos facility in October 2022, when it is 11 million kilometers from Earth.

The DART mission relies on what is known as "kinetic blow" – in this case, eight meters long (2.4m) craft with a solar electric drive.

DART will be directed to the binary asteroid Dodimos close to the Earth, which measures about 800 meters.

WHAT CAN WE REJECT THE ASTESTOID COMPLETED WITH THE COUNTRY?

At the moment, NASA will not be able to deflect the asteroid if it goes to Earth, but it can mitigate the impact and take measures to protect lives and property.

This would involve the evacuation of the area of ​​impact and the movement of key infrastructure.

Knowing the trajectory of the orbit, size, shape, mass, composition, and rotational dynamics will help experts determine the severity of the potential impact.

However, the key to mitigating the damage is to find any potential threat as early as possible.

Nasa is currently moving forward with spacecraft-size spacecraft capable of preventing asteroids from clashing with the Earth. For the year 2024, a small asteroid-free asteroid test is planned.

This is the first mission to demonstrate the asteroid deflection technique for planetary defense.

A Dual Asteroid Diversion Test (DART) will use what is known as a kinetic stroke technique – a stroke of the asteroid to shift its orbit.

The impact will change the speed of the threatening asteroid with a small fraction of its total speed, but with this before the predicted impact, this small incline will increase over time to the great shift of the asteroid path away from Earth.

The largest NASA scientist recently said that the best way to defend the Earth from the asteroids is to build a new telescope that will reveal it as soon as possible.

Dr Emmy Minner of the laboratory for a NASA dip laboratory in Pasadena, California, said that trying to spot asteroids with current telescopes is like trying to spot a "lump of coal in the night sky".

In April 2019, its team proposed a new system designed to notice large meteors that could cause significant damage.

It will identify incoming asteroids capable of causing huge loss of life – just like a meteor that wiped out dinosaurs 66 million years ago.

They argue that this will give scientists more time to come up with a strategy for intercepting the rock.

A NASA scientist said that to defend Earth from dangerous asteroids is to detect them by heat with an infrared telescope called Camera Object Near Camera (NEOCam). The Catalina comet (in the photo) in 2015 was captured by a telescope called NEOWISE

Dr Emi Minner said that trying to spot asteroids through their "low light" is how to try to spot a "lump of coal in the sky of the night," but that the proposed mission from near the Earth will make a mission that will detect heat waves it is much more precise

However, incoming space rocks are not noticeable always before their arrival.

Amazing images published in March 2019 discovered a meteor that exploded in the Earth's atmosphere in December with ten times more force than the Hiroshima bomb – but nobody discovered it.

The incident occurred at 11:50 pm (18:30 EST) on December 18, 2018, over the Bering Sea – between Russia and Alaska – but has just been discovered.

It is believed to be the second largest meteor explosion in the last 30 years, and the largest of the high-profile Chelyabinsk incident.
