“Near-Earth objects” are’hurtling toward Earth, and NASA and the White House recently released an action plan for how to address them.

Jumping ahead.

“Near-Earth objects” are’hurtling toward Earth and NASA has a plan to make sure they don’t land in your lawn.’

No, we’re not talking UFOs. Near-Earth objects are’comets (cosmic snowballs of frozen gases, rock and dust the size of a small town)’and asteroids (basically, space rocks smaller than planets)’that pass within 28 miles of Earth’s orbit.

NASA asteroid warning: Could space agency NUKE near-Earth object hazards into oblivion?

The Interagency Working Group for Detecting and Mitigating the impacts of Earth-bound Near-Earth Objects, or DAMIEN, drafted an 18-page document on the risks posed by NEOs.

The proposal suggests using nuclear explosives as the “only feasible option” to protect the planet from impact.

NEOs are comets or asteroids attracted to Earth’s gravitational field and potentially headed for impact.

NEOs larger than 140 metres in diameter have the potential to cause irreparable damage to entire regions or continents – striking with the power of more than 60 megatons of TNT.

NASA outlines its plan to defend the Earth from asteroids

NASA knows how damaging a potential impact from smaller asteroids might be, highlighting the Tunguska event in its report. That incident refers to an asteroid, “approximately 40-60 meters in size” exploding over a Russian town in 1908, “levelling over 2,000 square kilometers of forest.”

It goes on to say that “there are over 300,000 objects larger than 40 meters that could pose an impact hazard and would be very challenging to detect more than a few days in advance.”

Jumping ahead.

NASA will continue to develop its capabilities to detect, track and remotely characterize NEOs, to provide “critical improvements” allowing for better understanding of asteroids ranging from 50 to 140 meters in size while also improving its capability to more accurately model and analyse NEOs and the effects they may have if they were to slam into the Earth.
