Do we need Space Defence Program?

It bothered me for a long time, and it still does, that what will happen if an asteroid would come to earth to destroy us like the one destroyed the whole species of Dinasours and it gives me great relief that our Government had not done a single thing about it.

Well in 2018, NASA, National Nuclear Security Administration collaborated to produce Hypervelocity Asteroid Mitigation Mission for Emergency Response (HAMMER) satellite to deflect a big asteroid or chunk it into small asteroids. But this strategy wouldn’t work for big asteroids that appear out of the cosmic gloom with little warning; there wouldn’t be enough time for the missiles to take effect.

NASA is considering asteroid 101955 Bennu, which has a diameter of 246 meters and 1.15 gigaton impact.

Just because these plans now exist does not mean the spacecraft will ever get built. NASA scientists declined to give a cost estimate for a mission.

Earth has been hit by asteroids with regularity for the last 4.6 billion years, from the 6-mile-wide(10 km) one blamed for the end of the dinosaur era 66 million years ago. If you don’t believe you can ask Dinosaurs, oh wait you can’t, they are extinct because asteroid collison.

Here are some stats to show my concern, the closest encounters of asteroids.

It's not that we haven’t figured out the way for deflecting or destroying asteroids, I disagree that we lack the technology to build such devices, it’s the matter of will and determination, that we lack and the reason being some political issues or unable to imagine the world in far future.

The fear of human extinction by the virtue of meteorites or asteroid collision also advocates the fact that we should start to take planetary travel seriously. It can save humanity or if I may say human species (cause humanity is long lost) from extinction.

Some people say that earth is our home, and we can’t find another one like this, well that might not be all wrong, but eventually, we will exhaust our precious resources which we are using relentlessly, what will happen then?

We don’t know what future holds for us, we can just learn from the past, appreciate present, and prepare for the future.
