Shockingly fast way to deflect asteroids found

Hollywood has always fantasized about the end of the world caused by malicious asteroids. Apocalyptic movies like Deep Impact, Armageddon and Don't Look Up have explored the ‘What Ifs' of world destruction, with the most famous means of world destruction being asteroids crashing into Earth. If you've ever wondered what would happen if such an asteroid headed for Earth, then NASA already has an answer for you with its DART Mission. NASA successfully deflected an asteroid of its course in a first-of-its-kind mission just months ago. But what if an asteroid comes suddenly out of nowhere and gives us no warning or time to prepare? Scientists they can build a rapid-response kinetic impactor mission quickly. Their focus was on developing a Guidance, Navigation, and Control (GNC) system for a Kinetic Impact mission.

A recent study was conducted by Adalberto Dominguez, Víctor M. Moreno, and Francisco Cabral, three researchers working with Spanish satellite developer GMV. According to the study, the team have devised a Guidance, Navigation, and Control system required for an immediate kinetic impact mission to deflect an asteroid off its course. According to Universe Today, space agencies have 3 contingency plans in case of a potential asteroid impact – gravity tractor, nuclear standoff and kinetic impactor.

Speaking to Universe Today via email, Dominguez said, "The applicability of the nuclear standoff is still to be demonstrated, and their target would be asteroids with a diameter in the order of several km. Those asteroids are not a threat nowadays, as the great majority are monitored. Moreover, the Outer Space Treaty of 1967 banned nuclear detonations in outer space. The gravity tractor targets more interesting asteroids in the
