Asteroid behaving unexpectedly after Nasa's deliberate Dart crash

"However, using their school telescope, a team of children and their teacher Jonathan Swift at Thacher School in California have found that more than a month after the collision, Dimorphos' orbit continuously slowed after impact... which is unusual and unexpected."

Hubble ziet rotsblokken van Dimorphos wegdrijven

Eigenzinnige asteroïden vormen een reëel botsingsgevaar voor de Aarde. Wetenschappers schatten dat een asteroïde van enkele kilometers in doorsnee 65 miljoen jaar geleden op de Aarde insloeg en de dinosaurussen, naast andere levensvormen, uitroeide in een massale uitsterving.

Gizmodo: Hubble Spots ‘Boulder Cloud’ From NASA’s Asteroid-Smashing DART Mission https://gizmodo.com/hubble-spots-boulder-cloud-from-nasa-s-dart-mission-1850660574 #planetarydefensecoordinationoffice #doubleasteroidredirectiontest #solarsystemexplorationprogram #asteroidimpactavoidance #planetarydefense #inspaceflight #65803didymos #environment #davidjewitt #dimorphos #asteroids #lander #nasa #hera

Astronomers using #Hubble have discovered a swarm of boulders were shaken off the asteroid #Dimorphos when NASA deliberately slammed the half-ton DART impactor probe into the asteroid as a test of asteroid deflection in 2022: https://bit.ly/3pTqLw5

The five Nature papers about the outcome of the #impact of #DART into #Dimorphos are now available open access *and* in the final layout through links in the box at the top of https://www.nature.com/nature/volumes/616/issues/7957

The outcome of the #DART impact into #Dimorphos is discussed everywhere right now: https://www.youtube.com/watch?v=h7HJj-X-tyM = the recording of a press conference at #LPSC2023

Best presentation - IMHO :-) - of selected #Hubble images of #Dimorphos' ejecta after the #DART impact from the press release https://www.psi.edu/news/dartimpactejecta which also comes with a 19-second video. Also at https://www.nature.com/articles/s41467-022-35561-2 an article about the observations and their implications.

This time-lapse from Hubble shows rapid changes to the asteroid Dimorphos after it was deliberately hit by the 1,200-pound NASA DART spacecraft in September. This impact was a test to see if asteroids could be deflected away from Earth: http://bit.ly/3ZK1zVh

‘Puin’-asteroïden zijn verrassend lastig te vernietigen

Een onderzoeksteam denkt dat zogenaamde puin-asteroïden lastig zijn te vernietigen en dat ze zeer algemeen in ons zonnestelsel voorkomen.

In case you wondered ... YES, the man-made tail of asteroid-turned-not-so-temporary-comet #Dimorphos is still strong three full months after the impact of #DART that created it: https://www.facebook.com/photo/?fbid=5808460945911327 (the general thinking seems to be that a substantial debris cloud was formed around the poor moon of #Didymos which is constantly feeding this dust tail thanks to solar radiation pressure - but AFAIK nobody had predicted such a long persistence of this effect).

What Kind of an Impact did DART Have on Dimorphos? The Science Results are Here

On September 26th, NASA’s Double Asteroid Redirection Test (DART) spacecraft collided with Dimorphos, the small moonlet that orbits the larger Near-Earth Asteroid (NEA) Didymos. The purpose was to test a planetary defense technique known as the kinetic impact method.

What we learned from the #DART impact into the asteroid moon #Dimorphos in September was discussed Thursday at the #AGU press conference https://www.youtube.com/watch?v=FF-5B7_FMfY and in the press release https://www.nasa.gov/feature/early-results-from-nasa-s-dart-mission - the key result is that 1000+ metric tons of mass were ejected in the direction from where the spacecraft had come which led to a momentum enhancement factor of roughly 3.6. Good for an actual planetary defense application ... if one is ever needed.
