NASA's Asteroid-Smashing Space Debris Spotted By Hubble Telescope
Hubble Telescope Discovers NASA's Space Debris From Smashing An Asteroid
37 rocks, measuring between one and seven meters in diameter, were also sent by the collision, according to new Hubble Space Telescope photos.
NASA's DART probe collided with the far-off asteroid Dimorphos last year. The resultant debris has now been recorded in breathtaking detail by the Hubble Space Telescope. On September 26, 2022, DART purposefully collided with Dimorphos, slightly altering the course of its orbit around the bigger asteroid Didymos.
According to a NASA press release, astronomers have now used the Hubble telescope to find a cluster of rocks that may have been blasted loose from the asteroid by NASA's deliberate collision of the DART impactor spacecraft with Dimorphos at a speed of about 14,000 miles per hour.
New Hubble Space Telescope photos reveal that the impact also launched 37 rocks into space, with sizes ranging from one meter (three feet) to seven meters (22 feet).
According to a recent research, they make up about 2% of the pebbles that were already dispersed throughout the surface of the asteroid's surface.
The discovery implies that potential future attempts to deflect potentially dangerous asteroids approaching for Earth would also launch rocks in our way.
But the Earth is not in danger from these specific rocks; in fact, they have scarcely moved.
According to a statement from Hubble, they are moving away from Dimorphos at a rate of around one kilometer (half a mile) each hour, or about the speed of a gigantic tortoise.
The stones are travelling so slowly that they will even be visible to the European Space Agency's Hera mission, which is scheduled to visit the asteroid in late 2026 to assess the damage.
According to David Jewitt, a planetary scientist at the University of California, Los Angeles and the study's principal author, "the boulder cloud will still be dispersing when Hera arrives."
He described it as "like a very slowly growing swarm of bees."
Hubble's "spectacular observation" It also "tells us for the first time what happens when you hit an asteroid and see material coming out," the speaker continued.
The boulders are among the faintest objects that have ever been captured on camera in our solar system.

According to Jewitt, the dispersion of the stones suggests that DART left a crater on Dimorphos that was about 50 meters (160 feet) broad. The asteroid measures 170 meters wide overall.
