The National Aeronautics and Space Administration highlights vulnerability in the asteroid observation network of our Earth. This vulnerability focuses on a space rock which possesses a caliber to plow into Earth with a little alert.
Lindley Johnson said, “There was only a ‘limited’ chance of spotting asteroids coming from a certain direction in space.” This statement from Lindley Johnson comes ahead in the conference with the journalists. Lindley Johnson is a Planetary Defence Officer from the Space Agency.
The more massive objects in space are more accessible to track while the smaller ones mark their presence on the horizon before its impact.
At the beginning of this month, a tiny space rock exploded over Botswana. The stone is named as 2018 LA. Just before its explosion over Botswana, astronomers succeeded in spotting it. Fortunately, owing to its small size, the rock exploded in the sky itself and caused minimal damage. Instead of this, if the stone would have been comparatively larger, it might have resulted in unexplained damage. The severity of the accident might have wiped out the cities and ultimately gave rise to devastations on a continental scale.
Lindley Johnson conveyed that the NASA uses a ground telescope. With the ground telescope, scientists at the NASA observes the sky at night. It thus says that, if the space asteroids approach from the day side of our planet, the sun might shine extra-ordinarily. The brightly shining Sun might be difficult for us to spot.
Lindley Johnson further adds, ‘If the object is coming into the inner solar system and approaching Earth from the night side, our chances are pretty good of picking up objects of almost any size as they come close to Earth. The smaller it is the closer it would have to come to earth for us to detect it. ‘But we have a vulnerability from the day side if asteroids have already had their closest approach to the sun, which is called their perihelium, then coming back out of the Solar System and approaching earth from the day side our capability to detect them ahead of time right now is very limited.”
