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."

After #NASA’s #DART mission slammed into #asteroid #Dimorphous in September 2022, #scientists determined the impact caused tons of rock to be ejected from the small asteroid’s surface. But more importantly, DART’s impact altered Dimorphos’ #orbital period, decreasing it by about 33 minutes.

lol, search for "chicxulub impactor" on google and this whizzes across the screen! Has this always been there? #google

The scale of things out there …

“For Jupiter this was a small impact event. Large collisions, like from Comet Shoemaker-Levy 9 in 1994, left dark splotches on the Jovian surface, including one the diameter of Earth.”

“It sounds like something out of Deep Impact, Armageddon, or Don’t Look Up. But it’s possible that a small but dangerously sized asteroid could evade detection until it’s mere weeks away, rather than years or decades.”

#NASA to test potential 400Mbps laser link for #Mars
The Deep Space Optical Communications (#DSOC) experiment will head off into the void with #Psyche, an #asteroid-chasing probe that is scheduled to blast off on October 5. While they journey toward #16Psyche, a metal-rich asteroid, the DSOC system will spend two years attempting to communicate via laser with two ground stations in Southern California.

#University of #California 📆 August 17, 2023 “The boulder swarm ☄️☄️☄️ is like a cloud of #shrapnel expanding from a hand grenade. Because those big boulders basically share the #speed of the targeted #asteroid, they’re capable of doing their own damage.” A 15-foot (5m) boulder hitting #Earth would deliver as much energy as the atomic bomb 💥 that was dropped on #Hiroshima https://www.universityofcalifornia.edu/news/planetary-defense-test-deflected-asteroid-unleashed-boulder-swarm

Prediction · #ElonMusk was the #Chicxulub #asteroid that #doomed the #socialmedia #dinosaurs. They’re still vertical, but staggering. A few misguided souls are trying to breed new dinosaurs with the hope of owning and monetizing the world’s conversations.

#Mastodon(s) are mammals; unlike mastodons, the players in the Fediverse aren’t huge, they are the little furry mammals scurrying around those unsteady dinosaur feet. #Federation is the only #plausible way forward.
