In the opening hours of its surprise attack in early October, Hamas executed coordinated drone strikes against Israeli watchtowers and security cameras. These attacks were designed to blind the Israel Defense Forces’ surveillance of Gaza, clearing the way for armed assailants to infiltrate Israel and attack civilians with impunity.Such ad hoc fleets of low-cost drones have played prominent roles in other recent conflicts, including Ukraine’s fight against Russian forces and Azerbaijan’s strategy in the Nagorno-Karabakh…

Flow chart showing the workflow followed in this study. Credit: Geochemistry, Geophysics, Geosystems (2023). DOI: 10.1029/2023GC010867 Most of the earthquakes rumbling under the West's Great Basin come in surges, clustered together in time and place. Scientists call these seismic groups "swarms," which are a distinct category from the numerous aftershocks following a big shake, such as the 5.7 magnitude Magna quake of 2020 on…

Center of mass trajectories of different attractors for N=128, R0=v0=1, η=0 and different β. (a) Period 2 (β=60000) and period 4 (β=300) attractors. (b) Quasiperiodic attractor that appears at β=2N=256. (c) Periodic solutions with larger periods: 6 (β=N=128), 5 (β≈177), and 13 (β≈225). (d, e) Torus-like chaotic attractor for β=1 depicted for a long and a shorter time interval. (f) Chaotic attractor for β=0.01 : the center-of-mass trajectory will fill a…

In an autonomous orbital ballet, Lockheed Martin's In-space Upgrade Satellite System (LM LINUSS) completed a demonstration of how highly automated CubeSats can upgrade and service increasingly common constellations of small satellites.One constant of commercial space operations is that launching satellites is always expensive and that it is often cost effective to simply abandon an otherwise perfectly good orbital asset because of a malfunction.That attitude has been changed in recent years with companies like Northrop…

NASA’s Lucy spacecraft is still millions of miles from its destination, where it will study the Trojan asteroids. Despite that distance, the Lucy mission has captured a first glimpse of these mysterious asteroids in a new video, which NASA shared on Twitter. The Trojan asteroids are some of the more mysterious asteroids that humanity has discovered. These asteroids are made up of two swarms, trapped both in front of and behind Jupiter as it orbits our star. Lucy will study the Trojan asteroids to discover if…

Swarm tells the tale of a young woman named Dre (Dominique Fishback), just one of the countless fans who see global megastar Ni’Jah (Nirine S. Brown) as their lord and savior as well as a multiplatinum artist. As part of the “swarm” — Ni’Jah’s legion of dedicated fans who consume her music with a religious fervor — Dre isn’t used to feeling utterly alone. But when Dre’s sister and fellow fan Marissa (Chloe Bailey) begins to pull back, Dre’s relationship with the concept of Ni’Jah starts to shift, and Swarm’s new trailer…
