Asteroids have the potential to wipe out all life on Earth and even destroy the planet, just like the dinosaurs 65 million years ago. Fortunately, however, technology and science have advanced a lot since the dinosaurs were wiped out millions of years ago.
We now have technologies that scan the sky to detect potentially dangerous asteroids to Earth. Of course, it’s not just about detecting asteroids: As those of you who watched Don’t Look Up will remember, if we were to detect an asteroid on a collision course with our planet, we probably wouldn’t have enough time to respond to it. That’s why NASA is conducting research for a defense system that can destroy an asteroid that could destroy the Earth days or weeks before.
Existing asteroid destruction systems remain ‘insufficient’
NASA’s Near-Earth Object Observations (NEOO) Program has so far 28 it has detected a thousand celestial bodies; however, detecting these objects alone is not enough. If we are going to detect a huge asteroid heading towards our planet, we need systems to defend ourselves to get rid of it. NASA’s DART mission is working on exactly this right now. It aims to change the direction of the asteroid named Didymos B, which does not pose any threat to the Earth with its DART mission, for testing purposes.
However, there is a problem that for this method to work, we need to know about the existence of the asteroid months or even years ago. Considering that our discovery of asteroids is usually only after huge rocks get close to our planet, this means that the DART system is insufficient at some point.
Here’s the new Terminal Defense method for Humanity, named ‘Pi’, and aims to eliminate this time constraint. Designed by Philip Lubin, an engineer at the University of California Santa Barbara, the project, unlike DART, aims to ‘destroy’ the asteroid rather than deflect it. With the
Pi system, it is aimed to destroy asteroids in a much shorter time
Pi, a series of small sticks fired at the asteroid and the asteroid that will burn harmlessly in the Earth’s atmosphere. It is based on the principle of breaking down into much smaller parts. Depending on the size of the asteroid, these piercing rods could be sent in 10 x 10 arrays each with a mass of 100 kg (220 lb) or in 50 x 50 arrays of 40 kg (88 lb) each, launching several waves of missiles at an asteroid, and the system’s nuclear It is stated that it can be strengthened with weapons. On the other hand, Lubin notes that the Pi can be deployed to the Moon in order to reach the target quickly.
According to Lubin’s calculations, a 50-metre asteroid could be stopped only five hours before it hit the Earth; It is stated that the destruction of a 100-meter asteroid can be destroyed within 1 day. In fact, it is claimed that it will take 10 days to destroy the 370-meter-long Apophis asteroid, which is expected to pass by the Earth in 2029 and that conspiracy theorists claim will bring the end of the world.
Of course, it should be noted that the Pi system is still just a concept. However, with NASA’s increased interest in the project, Pi could be of great importance for the defense of our planet in the future.
