NASA's DART spacecraft changed a binary asteroid's orbit around the sun, in a first for a human-made object
When NASA crashed a spacecraft into the asteroid moonlet Dimorphos in 2022, it altered both Dimorphos' orbit around its parent asteroid, Didymos, and the two objects' orbit around the sun, according to new research. NASA's Jet Propulsion Laboratory (JPL) said in a press release that this "marks the first time a human-made object has measurably altered the path of a celestial body around the Sun." It's a promising result as scientists work to find a feasible method of defending Earth from hazardous space objects.

The Double Asteroid Redirection Test (DART) mission was designed to demonstrate one possible way of deflecting such an object, targeting the non-threatening moonlet Dimorphos, which is about 560 feet wide. NASA quickly declared it a success after its initial analysis showed the planned collision shortened Dimorphos' orbit around Didymos, the larger of the two objects in the binary asteroid system. In a follow-up study published in 2024, a team at NASA's JPL reported that Dimorphos' orbital period had been trimmed by about 33 minutes, as its path was nudged roughly 120 feet closer to Didymos than before. The latest study now indicates that the whole binary system was affected, not just Dimorphos. 

Didymos and Dimorphos have a 770-day orbital period around the sun, which lead author Rahil Makadia said has been changed by "about 11.7 microns per second, or 1.7 inches pe

Anthropic gives its flagship generative AI models a facelift
One of the hottest startups in the generative AI (genAI) market, Anthropic, has updated its flagship models to a new 3.0 standard, bringing improvements across a range of common tasks and faster processing speeds.

The improvements in Claude 3 are broad-based, according to Anthropic. The model now offers fewer "incorrect" refusals to process harmless requests, better accuracy in its answers, fewer  hallucinations, and better accuracy in processing visual information such as pictures and diagrams.

Anthropic now offers three versions of the Claude AI: the fully-featured Opus, middle-ground Sonnet, and lightweight Haiku. Each version offers different average benchmark scores across various tasks, with the lower-scoring Sonnet and Haiku trading off accuracy for lower costs, in the formeof cheaper tokens for AI calls, and faster response time.
