in firstPlanets forever defense testNASA hit Monday’s target point when it hit an asteroid 11.27 million kilometers (7 million miles) away in in order to deflect its orbit.
Historical test adds to me humanity’s ability To prevent a celestial body from destroying life on a land.
Double Asteroid Redirection Test (DART) Collider hit its target space Rock Dimorphos, 7:14 PM ET (11:14 PM GMT), 10 months after the bombing off from California on its leadership mission.
“We’re about to get started on a new era, era in That we probably have the ability to protect ourselves from something like Laurie Gillies said, director of NASA Planets science division.
Dimorphos – A 160-meter (530-foot) asteroid roughly comparable in Size of the Egyptian pyramid – orbits A half- a long mile big brother It is called Didymus. Never seen before, the ‘moon’ appeared in the form of a spot of light about an hour ago collision.
her egg-like shape Finally he entered the rocky surface full of boulders clear view in The last A few minutes later, as DART sprinted toward it at 23,500 kph (14,500 mph).
NASA scientists and engineers broke out in Applause as the screen froze on a final Picture, indicating that signal Lost and take effect place.
is being surethe husband of Asteroids do not pose any threat to our planet because they revolve around the sun every Monday of our years.
But NASA considered the experiment important out before the actual need was discovered.
Hit Dimorphos head-onNASA hopes to push it into a smaller orbit, and fly for 10 minutes off The time taken to encircle Didymos, which is currently 11 hours and 55 minutes.
Ground-based telescopes – that can’t see the asteroid system directly But the transformation can be detected in patterns of light coming from him – should Provides a final orbital period in the coming days and weeks.
the proof-ofHe has a concept made a reality of What has been tried before? in science Fantasy – in particular in Movies like “Armageddon” and “Don’t Look Up”.

Minutes after the collision, a toaster-sized satellite called LICIACube, which already I broke up with DART a few weeks ago, and was expected to end pass of site for capture Pictures of The collision And tossing – crushed rocks thrown off by strike.
LICIACube photos will be sent back in The next weeks and months.
as watching event: Collection of Telescopes, both on earth and in space – including recently turned on James Webb – who may be able to see a bright cloud of soil.
The mission she has set The global astronomy community sizzling with more More than thirty ground-based telescopes participate, including optical, radio and radar telescopes.
“There is a lot of Dart said: mission Planetary astronomer Christina Thomas.
Finally, a full picture of what system look like It will be revealed when the European Space Agency mission four years down The font named Hira arrives To survey the surface of Dimorphos and measure its mass, which scientists can do currently Just guess at.
Earthlings can sleep better
A little bit of billions of asteroids and comets in Our solar energy system They are considered dangerous to our planet, and none of them are expected in The next A hundred years or so.
But wait too long, and it will happen.
we know That’s geology record – for For example, the 9.65 kilometers (6 miles) wide asteroid Chicxulub hit Earth 66 million years ago, sinking world In a long winter that led to a mass extinction of dinosaurs all along with 75% of all types.
asteroid size of By contrast, only Dimorphos cause Regional influence, such as Terminator A citylo with Larger force From which nuclear bomb? in history.
How Much Momentum Does DART Give? on Dimorphos will adopt on Whether the asteroid is a solid rock, or more like “trash heap” of Rocks related to mutual gravity – A property This is not yet known.
If she had missed it, NASA would have had another chance in two years time, with spaceship containing just enough fuel for else pass.
but it success classify the first step towards a world able of defending himself from future existential threat.
“I think Earthlings can sleep better, for sure I will,” DART said. mission Systems Engineer Elena Adams.
