The head of NASA warns that a great asteroid could fall to Earth during his lifetime, and calls for a global study on the threat to our planet.
- Bridenstine spoke at a conference in Washington, DC, of the planetary defense.
- He said catastrophic asteroids could potentially collide with Earth in our lives
- Comes when NASA performs a defense exercise simulating an asteroid collision.
NASA Administrator Jim Bridenstine believes that the prospect of a killer asteroid colliding with Earth is not just science fiction is reserved.
Bridenstine argued why the US should step up its defense against meteorite events Monday at the 2019 Planetary Defense Conference in Washington, DC.
It happens that NASA, the Federal Emergency Management Agency and other parties will be conducting an organization defense exercise at the conference that simulates what it would be like when an asteroid headed straight for Earth.

"We need to make sure people understand that it's not Hollywood, it works not about movies, "said Bridenstine at the conference.
"It's about protecting the only planet we know at the moment to host life, and that's the planet earth."
He pointed to the Chelyabinsk event as evidence of the increasing seriousness and potential of these events.
The meteor that fluttered across the Southern Ural Mountains in February 2013 was the largest meteorite strike in more than a century after the Tunguska event of 1908.
Over 1,600 people were injured by the shockwave The explosion was estimated at 20 Hiroshima nuclear bombs.
Although these events occur once every 60 years, Bridenstine claims to have occurred three times in the last 100 years.
Bridenstine's comments come from NASA, the Federal Emergency Management Agency and other parties at the conference's defense exercise, which simulates what it would be like if an asteroid were heading straight for Earth
After this mindset, this means another Event during the Chelyabinsk event during our lifetime.
"I wish I could tell you that these events are exceptionally unique," said Bridenstine. "But they are not."
Bridenstine said that planetary defense is as critical as other NASA targets, such as the landing of humans on the moon.
He added that NASA is working to detect and track 90 percent of nearby asteroids that could cause 459 feet or more, possibly deadly impact damage.
One of NASA's efforts to defend the Earth against asteroids is the Double Asteroid Redirection Test (DART) mission, which is scheduled to take off in June 2021 and includes the help of Elon Musk's SpaceX.
The groundbreaking mission will be the first demonstrated attempt to distract an asteroid by intentionally nudging an object at high speed.
The launch of Californian Vandenberg Air Force base on a Falcon 9 rocket in 2021 sees the arrival of the DART vehicle The Didymos object is expected to arrive in October 2022, when it is 11.8 km from Earth.
The DART mission is based on a so-called "kinetic impactor" – in this case a 2.4-meter-long, solar-powered vehicle.
DART will aim at the binary near-Earth asteroid Didymos, which measures about 800 meters.
WHAT WE CAN DO THAT WE CAN COLLID ONE ASTEROIDS WITH THE EARTH?
Currently, NASA could not distract an asteroid when it targets Earth, but it could mitigate the effects and take action to protect lives and property.
These include the evacuation of the impact area and the displacement of the key infrastructure.
Determining the trajectory, size, shape, mass, composition, and rotational dynamics of the orbit could help the experts to determine the severity of a potential impact.
The key to mitigation is finding a potential threat as early as possible.
NASA is making progress with a refrigerator-sized spaceship that can prevent the collision of asteroids with the Earth. A test with a small, non-threatening asteroid is scheduled for 2024.
This is the first mission to demonstrate an asteroid diversion technique for planetary defense.
The Double Asteroid Redirection Test (DART) would use what is known as a kinetic impactor technique – hit the asteroid to shift its orbit.
The impact would change the speed of a threatening asteroid by a small fraction of its overall speed, but if he does so before the predicted impact, this small impetus will over time contribute to a large shift of the asteroid's path from Earth ,
