NASA believes an Asteroid could crash into Earth in your lifetime

NASA believes an Asteroid could crash into Earth in your lifetime”

Specifically, they will participate in a fictional scenario in which an asteroid has an impact trajectory with the Earth.

The five-day conference, being held in Maryland, is the sixth by the International Academy of Astronautics (IAA) on planetary defence and reflects the increasing recognition of the potential threat posed by objects in near- Earth orbit.

A U.S. conference that opened in Washington Monday will include an exercise to test how Nasa and the global community would respond to an asteroid found to be on a collision course with Earth.

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

"These events are not rare; they happen", said Bridenstine.

That's the ominous disclaimer and motto for an global conference involving NASA's Jet Propulsion Laboratory (JPL) and other groups underway in Washington, D.C. this week.

Bridenstine knows the perils of asteroid strikes all too well.

More than 1,600 people were injured by the shock wave triggered by the explosion which was equivalent to 20 times the size of the atomic bomb that fell on Hiroshima.

NASA is preparing for the end of the world with a "doomsday" rehearsal playing out this week.

Lindley Johnson, the space agency's planetary defense officer, said at the time that the country "already has significant scientific, technical and operational capabilities" to help with NEOs, but implementing the new plan would "greatly increase our nation's readiness and work with worldwide partners to effectively respond should a new potential asteroid impact be detected".

Davide Farnocchia, an astronomer at the JPL's Centre for Near Earth Objects Studies (CNEOS), for his part, cited 15 years of optical and radar tracking data on Apophis, which he said helps researchers have "a very precise estimate of its orbit through the 2029 encounter with the Earth".

According to NASA Administrator Jim Bridenstine, these sorts of meteor impacts could happen much more frequently than we might realize.

NASA however has detailed plans to track the movements of as many as 90 percent of asteroids near earth, sizes 140 meters or larger.

There are approximately 18,000 known NEOs and that number is constantly growing.
