Earlier this week, the High-frequency Active Auroral Research Program (HAARP) antenna arrangement in Alaska transmitted

an alternation of long-wavelength radio signals to an asteroid that was casually aloof two lunar distances abroad from the Earth.

The celebration is that the signals will accept penetrated the asteroid, giving scientists an abstraction of its centralized makeup,

and arming them with an additional allotment of advice that could be analytical in arresting the planet from an anytime collision.

Most asteroid-observing programs actuality on Earth use either beheld studies of asteroids 

Radio waves from Alaska

– such as those provided by observatories beyond the apple to NASA's Center for Near Earth Object Studies (CNEOS)

 – or short-wave radio frequencies including those provided by NASA's Deep Amplitude Network to map the size, positions, and paths of asteroids.

While these programs accommodate acutely admired abstracts apropos any abeyant crisis from an asteroid impact, they are bound in that they alone "see" the appearance of the asteroid.

HAARP, which is operated by the University of Alaska Fairbanks, has commonly been acclimated to backpack out the assay of our ionosphere (and has alike been active in a few cabal theories).

 It additionally has the adeptness to accelerate out long-wavelength radio signals. Such signals are able to access objects, absolution assemblage gets an abstraction of their centralized structure.

In this case, acquirements about the centralized architectonics of an asteroid could accommodate scientists with

a way to one day draft up or avert an amplitude bedrock that's accepting a little too abutting to Earth for comfort.
