NASA and Other Space Agencies Deploy Largest Planetary Defense Drill in History as Interstellar Comet 3I/ATLAS Approaches Planet Earth
The ‘visitor from outside’ is near us.
And so, we come to the moment in which 3I/ATLAS, the third interstellar object ever to be observed, is making its closest approach to Planet Earth.
Leaving aside the multitude of UFO theories that have been splashed on MSM headlines, there is no doubt that the Manhattan-sized comet is of great scientific interest – including to train Space Agencies around the world on how to operate if some day – God forbid – the human race is faced with an object like that on a collision course.
And for that, a major planetary defense drill is ongoing.
Daily Mail reported:
“The European Space Agency (ESA), NASA, and more than 23 nations have launched the largest drill in history which will run through January 2026, using the suspected comet’s harmless passage through the solar system as a test for tracking future threats from space.
3I/ATLAS is expected to come within 170 million miles of Earth on Friday, and space agency officials have said there is no risk of a potential collision with the interstellar object.”

The objective is to learn more about high-velocity near-Earth objects (NEOs) that could one day impact the planet.
DON’T MISS OUT: Rare interstellar comet 3I/ATLAS will make its closest pass to Earth yet on Friday, Dec. 19 and can be seen by ground-based telescopes, according to NASA .

European Space Agency: “‘Hazards originating in space carry the risk of sudden disaster and potentially derailing everyday life, from natural threats like asteroids and solar storms to the human-made one of space debris,’ ESA wrote in a statement’.”
[…] At the heart of their plans, space agency officials said that Earth needs an asteroid deflection system, meaning a way of shifting the course or destroying space rocks projected to hit our world.
‘It is no longer sci-fi, it is a skill we must hone before it is needed,’ the agency added.”
